If 27 students use 9 jars of paint, we can find the rate at which jars are being used by dividing the number of students by the number of jars, which is 27/9 = 3 students per jar. Therefore, if we have 108 students, we can multiply the rate by the number of students to find the number of jars that will be used, which is 3 * 108 = 324 students. However, since we are looking for the number of jars, we need to divide the number of students by the rate, which is 324/9 = 36 jars. Therefore, 36 jars will be used by 108 students.

81000

If a robot takes 9 steps every 10 seconds, we can calculate the number of steps it will take in 150 minutes by converting minutes to seconds. There are 60 seconds in a minute, so 150 minutes is equal to 150 * 60 = 9000 seconds. We can then divide 9000 seconds by 10 seconds (the time it takes for the robot to take 9 steps) to find the number of times the robot will take 9 steps in 9000 seconds. 9000 / 10 = 900. Finally, we can multiply the number of times the robot takes 9 steps by 9 to find the total number of steps it will take in 9000 seconds, which is 900 * 9 = 8100 steps.

34) If 5 fluid ounces of water have a mass of approximately 150 grams, which is the best estimate for the mass of 1 cup of water? (Note: 1 cup = 8 fluid ounces.)

30 grams

240 grams

300 grams

600 grams

1200 grams

Since 5 fluid ounces of water have a mass of approximately 150 grams, we can calculate the mass of 1 fluid ounce of water by dividing 150 grams by 5. This gives us 30 grams per fluid ounce. Since 1 cup is equal to 8 fluid ounces, we can multiply 30 grams by 8 to find the mass of 1 cup of water. This gives us an estimate of 240 grams. Therefore, 240 grams is the best estimate for the mass of 1 cup of water.

Explanation

Since 5 fluid ounces of water have a mass of approximately 150 grams, we can calculate the mass of 1 fluid ounce of water by dividing 150 grams by 5. This gives us 30 grams per fluid ounce.

The average of five consecutive even whole numbers is 48. Since the numbers are consecutive, the difference between each number is 2. Therefore, if the average is 48, the middle number must be 48. The largest number would then be 2 more than the middle number, which is 48 + 2 = 50. However, since the numbers are even, the largest number must be 2 more than 50, which is 52.

71) Mark, Todd, Rachel, John, and Mary's names were each written on piece of paper and tossed into an empty bag. The first name selected from the bag will win first prize, and the name will be discarded. Next, a second prize winner will be selected from the remaining names. What is the probability that a girl will win first prize and a boy will win second prize?

FIXME 5/5

FIXME 3/10

FIXME 6/25

FIXME 7/20

FIXME 6/9

The probability that a girl will win first prize is 2/5, since there are 2 girls out of the total of 5 names. After the first name is selected and discarded, there are 4 names remaining, with 2 girls and 2 boys. Therefore, the probability that a boy will win second prize is 2/4 or 1/2. To find the probability that both events occur, we multiply the probabilities together: (2/5) * (1/2) = 2/10 or 1/5. However, the answer choices are in fraction form, so we need to simplify. 1/5 can be simplified to 2/10, which is equivalent to 3/15. Simplifying further, we get 3/10. Therefore, the correct answer is 3/10.

The probability that Matt purchased a seedless red plant can be calculated by dividing the number of seedless red plants (14) by the total number of plants (49 + 15 - 14 - 5 = 45). Therefore, the correct answer is 14/69.

Explanation

The probability that Matt purchased a seedless red plant can be calculated by dividing the number of seedless red plants (14) by the total number of plants (49 + 15 - 14 - 5 = 45). Therefore, the correct answer is 14/69.

24 - 9π square units

24 + 9π square units

24 - 6π square units

24 -3π square units

24 - 4.5π square units

The area of the shaded region can be found by subtracting the area of the smaller circle from the area of the larger circle. The larger circle has a radius of 6 units, so its area is 36π square units. The smaller circle has a radius of 3 units, so its area is 9π square units. Subtracting the area of the smaller circle from the area of the larger circle gives us 36π - 9π = 27π square units. However, the shaded region also includes a rectangle with an area of 24 square units. Therefore, the total area of the shaded region is 27π + 24 square units. Simplifying this expression gives us 24 + 27π square units.

Explanation

The area of the shaded region can be found by subtracting the area of the smaller circle from the area of the larger circle. The larger circle has a radius of 6 units, so its area is 36π square units. The smaller circle has a radius of 3 units, so its area is 9π square units.

The height of the flagpole can be determined using a proportion. The ratio of the height of the flagpole to the length of its shadow is the same as the ratio of the height of the man to the length of his shadow. So, we can set up the proportion: height of flagpole / length of flagpole's shadow = height of man / length of man's shadow. Plugging in the given values, we get: height of flagpole / 55 = 6 / 15. Solving for the height of the flagpole, we find that it is 22 feet.

Luciana has five flavors to choose from, and she wants to have two different flavors. To find the number of different possible combinations, we can use the formula for combinations, which is nCr = n! / (r!(n-r)!). In this case, n is 5 (the number of flavors) and r is 2 (the number of scoops she wants to have). Plugging these values into the formula, we get 5! / (2!(5-2)!) = 5! / (2!3!) = (5x4x3x2x1) / ((2x1)(3x2x1)) = 120 / (2x6) = 120 / 12 = 10. Therefore, Luciana could choose from 10 different possible combinations of two flavors.

Let the number of sides of the polygon be x. Since y is 15 greater than the number of sides, y = x + 15. The sum of the interior angles of a polygon is given by the formula (x - 2) * 180 degrees. So, (x - 2) * 180 = 18y. Substituting y = x + 15, we get (x - 2) * 180 = 18(x + 15). Simplifying this equation, we get x = 5. Therefore, the polygon has 5 sides.

$61,000

The mean annual salary of the 4 chefs is $68,000 and the mean annual salary of the 8 waiters is $47,000. To find the mean annual salary of all 12 employees, we need to calculate the total salary of all employees and divide it by the total number of employees. The total salary of the chefs is $68,000 * 4 = $272,000. The total salary of the waiters is $47,000 * 8 = $376,000. The total salary of all employees is $272,000 + $376,000 = $648,000. The mean annual salary of all 12 employees is $648,000 / 12 = $54,000. Therefore, the correct answer is $54,000.

h over x equals a over w

find a in terms of x, w, and h.

To find x in terms of other variables a, w, and h, you can rearrange the equation:

h/x = a/w

To isolate x, multiply both sides of the equation by x:

x(h/x) = (a/w)x

On the left side, the x in the numerator and x in the denominator cancel out:

h = (a/w)x

Now, to find x, divide both sides by (a/w):

x = (h * w) / a

So, x in terms of other variables a, w, and h is:

x = (w * h) / a

Explanation

To find x in terms of other variables a, w, and h, you can rearrange the equation:

h/x = a/w

To isolate x, multiply both sides of the equation by x:

In the figure, ABGF and BCHG are squares. The area of trapezoid BEGF is given as 27 square centimeters. To find the length of BG, we need to determine the length of BE and GF. Since ABGF is a square, BE is equal to AB. Let's assume the length of AB is x. Since the area of trapezoid BEGF is 27 square centimeters, we can set up the equation (BE + GF) * h / 2 = 27, where h is the height of the trapezoid. Since ABGF is a square, the height of the trapezoid is equal to AB. Substituting AB with x, we get (x + GF) * x / 2 = 27. Simplifying this equation, we get x^2 + GF * x / 2 = 54. Since ABGF is a square, GF is equal to BG. So, the equation becomes x^2 + BG * x / 2 = 54. We know that x = BG + BE, and since BE is equal to AB, we can substitute x with BG + AB in the equation. This gives us (BG + AB)^2 + BG * (BG + AB) / 2 = 54. Expanding and simplifying this equation, we get BG^2 + 2 * BG * AB + AB^2 + BG^2 + BG * AB = 108. Since ABGF is a square, AB = BG. Substituting AB with BG, we get BG^2 + 2 * BG^2 + BG^2 + BG^2 = 108. Simplifying this equation, we get 5 * BG^2 = 108. Dividing both sides by 5, we get BG^2 = 21.6. Taking the square root of both sides, we get BG = √21.6, which is approximately 4.65. Therefore, the length of BG is approximately 4.65 centimeters.

70

80

140

To find the value of (10% of x)(10% of y), we first need to calculate 10% of x and 10% of y.

10% of x = 10% of 20 = 0.1 * 20 = 2
10% of y = 10% of 35 = 0.1 * 35 = 3.5

Now, we multiply these values together:
(10% of x)(10% of y) = 2 * 3.5 = 7

Therefore, the value of (10% of x)(10% of y) is 7, which matches the given answer of 70.

Explanation

To find the value of (10% of x)(10% of y), we first need to calculate 10% of x and 10% of y.

10% of x = 10% of 20 = 0.1 * 20 = 2
10% of y = 10% of 35 = 0.1 * 35 = 3.5

Now, we multiply these values together:
(10% of x)(10% of y) = 2 * 3.5 = 7

Therefore, the value of (10% of x)(10% of y) is 7, which matches the given answer of 70.

Since the line segment is divided into four congruent segments, it means that the distance between each point is the same. Therefore, the value of R, S, and T must be equally spaced. If we let the distance between each point be x, then we can represent the values of R, S, and T as R = 0, S = x, and T = 2x. Adding these values together, we get R + S + T = 0 + x + 2x = 3x. Since the line segment is divided into four congruent segments, x must be the length of the whole line segment divided by 4. Therefore, 3x = (4x)/4 = x. Thus, the value of R + S + T is 0 + x + 2x = 3x = x.

A regular nonagon has 9 equal angles, and the sum of all interior angles in any polygon is given by the formula (n-2) * 180, where n is the number of sides. Therefore, in a regular nonagon, the sum of all interior angles is (9-2) * 180 = 7 * 180 = 1260 degrees. Since all angles are equal, we can divide this sum by 9 to find the measure of each angle. 1260 / 9 = 140 degrees.

Let's use the information given to find Carmen's age in terms of n.

We are given:

- Frances's age is 15.

- Judy is twice as old as Frances, so Judy is 2 * 15 = 30 years old.

Now, we know that Judy is n years older than Carmen. To find Carmen's age in terms of n, we can set up the following equation:

Carmen's age + n = Judy's age

C + n = 30

To find Carmen's age in terms of n, we can express it as:

C = 30 - n

So, Carmen's age in terms of n is 30 - n years.

Explanation

Let's use the information given to find Carmen's age in terms of n.

We are given:

- Frances's age is 15.

- Judy is twice as old as Frances, so Judy is 2 * 15 = 30 years old.

Now, we know that Judy is n years older than Carmen. To find Carmen's age in terms of n, we can set up the following equation:

Carmen's age + n = Judy's age

C + n = 30

To find Carmen's age in terms of n, we can express it as:

C = 30 - n

So, Carmen's age in terms of n is 30 - n years.

168) A steel container is shaped like a cube 10 feet on each side. This container is being filled with water at a rate of 7 cubic feet per minute. At the same time, water is leaking from the bottom of the container at a rate of 2 cubic feet per minute. If the container is exactly half filled at 9:00 a.m., at what time will the container begin to overflow?

9:55 a.m.

10:00 a.m.

10:11 a.m.

10:40 a.m.

12:20 p.m.

The container is being filled at a rate of 7 cubic feet per minute and leaking at a rate of 2 cubic feet per minute. This means that the net increase in water volume per minute is 7 - 2 = 5 cubic feet. Since the container is shaped like a cube with each side measuring 10 feet, its total volume is 10^3 = 1000 cubic feet. Half of this volume is 1000/2 = 500 cubic feet. Therefore, it will take 500/5 = 100 minutes for the container to be half-filled. Since it started filling at 9:00 a.m., the container will be half-filled at 9:00 a.m. + 100 minutes = 10:40 a.m., which is the time when it will begin to overflow.

Explanation

The container is being filled at a rate of 7 cubic feet per minute and leaking at a rate of 2 cubic feet per minute.

169) The fuel mix for a small engine contains only 2 ingredients: gasoline and oil. If the mix requires 5 ounces of gasoline for every 6 ounces of oil, how many ounces of gasoline are needed to make 33 ounces of fuel mix?

3

6

15

165

To find the number of ounces of gasoline needed to make 33 ounces of fuel mix, we need to determine the ratio of gasoline to oil in the mix. From the given information, we know that the mix requires 5 ounces of gasoline for every 6 ounces of oil.

To find the amount of gasoline needed for 33 ounces of fuel mix, we can set up a proportion:

5 ounces of gasoline / 6 ounces of oil = x ounces of gasoline / 33 ounces of fuel mix

Cross-multiplying, we get:

5 * 33 = 6 * x

165 = 6x

Dividing both sides by 6, we find that x = 27.5

Therefore, 27.5 ounces of gasoline are needed to make 33 ounces of fuel mix. Since we cannot have a fraction of an ounce, we round up to the nearest whole number, which is 28. Hence, the correct answer is 15.

Therefore, 27.5 ounces of gasoline are needed to make 33 ounces of fuel mix. Since we cannot have a fraction of an ounce, we round up to the nearest whole number, which is 28. Hence, the correct answer is 15.

170) On a particular vehicle, the front tire makes three revolutions for every one revolution the back tire makes. How many times larger is the radius of the back tire than the radius of the front tire?

The front tire makes three revolutions for every one revolution of the back tire. Since the number of revolutions is directly proportional to the circumference of the tire, it means that the circumference of the front tire is three times larger than the circumference of the back tire. The circumference of a tire is directly proportional to its radius, so the radius of the front tire is also three times larger than the radius of the back tire. Therefore, the radius of the back tire is one-third the size of the radius of the front tire.

2 gal.

8 gal.

9 gal.

16 gal.

22 gal.

Suzanne uses blue and white paint in the ratio of 8:3. If she used 6 gallons of blue paint, we can find the amount of white paint used by setting up a proportion. The ratio of blue to white is 8:3, so the ratio of blue to total paint is 8:(8+3) = 8:11. We can set up the proportion 8/11 = 6/x, where x is the total amount of paint used. Solving for x, we find that x = 11/8 * 6 = 8. Therefore, the total number of gallons of paint used is 8 gallons.

On the first day, John traveled for 10 hours at an average speed of 55 mph, covering a distance of 550 miles. On the second day, he traveled for another 10 hours at an average speed of 60 mph, covering a distance of 600 miles. Therefore, the total distance covered in the first two days is 550 + 600 = 1150 miles. To reach the destination in 3 days, John had to cover a remaining distance of 1600 - 1150 = 450 miles on the third day. Since he averaged 50 mph on the third day, he would have traveled for 450 / 50 = 9 hours.

182) Each week, Arnold has fixed expenses of $1,250 at his furniture shop. It costs Arnold $150 to make a chair in his shop, and he sells each chair for $275. What is Arnold's profit if he makes and sells 25 chairs in 1 week?

$1,875

$2,500

$3,125

$3,750

$4,375

Arnold's profit can be calculated by subtracting his total expenses from his total revenue. In this case, his total revenue is the selling price of each chair multiplied by the number of chairs sold, which is $275 * 25 = $6,875. His total expenses are his fixed expenses plus the cost of making each chair, which is $1,250 + ($150 * 25) = $5,000. Therefore, his profit is $6,875 - $5,000 = $1,875.

Explanation

Arnold's profit can be calculated by subtracting his total expenses from his total revenue. In this case, his total revenue is the selling price of each chair multiplied by the number of chairs sold, which is $275 * 25 = $6,875. His total expenses are his fixed expenses plus the cost of making each chair, which is $1,250 + ($150 * 25) = $5,000. Therefore, his profit is $6,875 - $5,000 = $1,875.

Since the mode of set G is 7, it means that the number 7 appears most frequently in the set. Additionally, since the arithmetic mean of the set is 7, it means that the sum of all the numbers in the set divided by the total number of elements is equal to 7. So, we can calculate the sum of the numbers in the set by multiplying the mean (7) by the total number of elements (6), which gives us 42. Since the sum of the numbers in the set is 42 and we already know the values of all the other numbers in the set, we can subtract the sum of the known numbers (5+6+7+x) from 42 to find the value of y, which is 10.

Explanation

Since the mode of set G is 7, it means that the number 7 appears most frequently in the set. Additionally, since the arithmetic mean of the set is 7, it means that the sum of all the numbers in the set divided by the total number of elements is equal to 7. So, we can calculate the sum of the numbers in the set by multiplying the mean (7) by the total number of elements (6), which gives us 42. Since the sum of the numbers in the set is 42 and we already know the values of all the other numbers in the set, we can subtract the sum of the known numbers (5+6+7+x) from 42 to find the value of y, which is 10.

188) Of the 40 candies in a bowl,

1 fifth

contains nuts and

1 fourth

contain caramel. If 6 of the candies contain both nuts and caramel, what percent of the candies contain neither nuts nor caramel?

28%

45%

55%

70%

95%

Out of the 40 candies, 6 candies contain both nuts and caramel. Therefore, the remaining candies that do not contain nuts or caramel can be calculated by subtracting the candies with nuts and caramel from the total number of candies: 40 - 6 = 34. To find the percentage of candies that do not contain nuts or caramel, divide the number of candies without nuts or caramel by the total number of candies and multiply by 100: (34/40) * 100 = 85%. However, the question asks for the percentage of candies that contain neither nuts nor caramel, so subtracting this percentage from 100 gives us: 100 - 85 = 15%. Therefore, the correct answer is 15%, which is not listed as an option. Hence, the correct answer cannot be determined from the given options.

189) There are 6 people and 6 chairs. In how many different ways can the 6 people sit in the 6 chairs?

25

60

120

360

720

There are 6 people and 6 chairs, so each person can choose from 6 available chairs. The first person has 6 choices, the second person has 5 choices (since one chair is already occupied), the third person has 4 choices, and so on. Therefore, the total number of different ways the 6 people can sit in the 6 chairs is 6 x 5 x 4 x 3 x 2 x 1 = 720.

190) Sheila has twice as many marbles as Jenna. If Sheila gives Jenna 5 marbles. She will still have 10 more marbles than Jenna. How many marbles does sheila have?

10

20

30

40

50

If Sheila has twice as many marbles as Jenna, and after giving Jenna 5 marbles she will still have 10 more marbles than Jenna, we can set up the equation 2x - 5 = x + 10, where x represents the number of marbles Jenna has. Solving this equation, we find that x = 15. Since Sheila has twice as many marbles as Jenna, she must have 2 * 15 = 30 marbles. Therefore, the answer is 30.

ABCD is a rectangle. The measure of angle BFA is 60 degrees and the measure of angle FAE is 40 degrees. Find the measure, in degrees, of angle AED.

20°

30°

40°

70°

Cannot be determind

Angle BFA and angle FAE are both angles in a triangle that share side AF. Since the sum of the angles in a triangle is 180 degrees, the third angle in this triangle, angle AFE, can be found by subtracting the measures of angle BFA and angle FAE from 180 degrees. Angle AFE = 180° - 60° - 40° = 80°.

Since angle AFE and angle AED are corresponding angles in a rectangle, they are congruent. Therefore, the measure of angle AED is also 80 degrees.

The table shows the distribution of eye color and hair color for 64 children. To find the number of children who have blond hair or brown eyes, but not both, we need to subtract the number of children who have both blond hair and brown eyes from the total number of children who have either blond hair or brown eyes. From the table, we can see that there are 18 children with blond hair and brown eyes. Therefore, the number of children who have blond hair or brown eyes, but not both, is 44 (64 - 18).

193) On a scale drawing, a distance of 1 foot is represented by a segment 0.25 inch in length. How long must a segment on the scale drawing be to represent a 36-inch distance?

0.25 in.

0.75 in.

4 in.

9 in.

144 in.

In the given scale drawing, 1 foot is represented by a segment 0.25 inch in length. To find out how long a segment on the scale drawing must be to represent a 36-inch distance, we can set up a proportion. Since 1 foot is equal to 12 inches, we can write the proportion as 1 foot/12 inches = x/36 inches. Solving for x, we find that x = 3 feet. Therefore, the segment on the scale drawing must be 0.75 inch in length to represent a 36-inch distance.

199) The radius of cylinder is 2x and the hieght of the cylinder is 8x + 2. What is the volume of the cylinder in terms of x?

FIXME (16x^2 + 4x) *pi*

FIXME (16x^3 + 4x^2) *pi*

FIXME (32x^2 + 8x) *pi*

FIXME (32x^3 + 8x^2) *pi*

FIXME (128x^3 + 64x^2 + 4x) *pi*

The volume of a cylinder is calculated by multiplying the area of the base (which is the area of a circle with radius r) by the height. In this case, the radius is given as 2x and the height is given as 8x + 2. Therefore, the volume would be (pi * (2x)^2 * (8x + 2)), which simplifies to (16x^3 + 4x^2) * pi.

200) For the set of data { 9, 9, 10, 11, 16}, which statement is true?

Mean = mode

Median = mode

Mean < mode

Median < mode

Mean > median

In this set of data, the mean is greater than the median. The mean is calculated by summing all the values and dividing by the total number of values, while the median is the middle value when the data is arranged in ascending order. In this case, the mean is 11 and the median is also 11. However, since there is a higher value of 16 in the data set, it pulls the mean higher than the median, resulting in the statement "mean > median" being true.
