### In trail mix, the ratio of cups of peanuts to chocolate candies is 3 to 2. How many cups of chocolate candies would be needed for 9 cups of peanuts?

• A.

6 cups

• B.

3 cups

• C.

4 cups

• D.

8 cups

A. 6 cups
Explanation
The ratio of cups of peanuts to chocolate candies is 3 to 2. This means that for every 3 cups of peanuts, there are 2 cups of chocolate candies. If we have 9 cups of peanuts, we can determine the number of cups of chocolate candies needed by setting up a proportion. 3 cups of peanuts is to 2 cups of chocolate candies as 9 cups of peanuts is to x cups of chocolate candies. Solving this proportion, we find that x = (2/3) * 9 = 6 cups of chocolate candies. Therefore, 6 cups of chocolate candies would be needed for 9 cups of peanuts.

### Which of the following has a unit rate of 17 miles per hour?

• A.

60 miles in 2 hours

• B.

85 miles in 5 hours

• C.

90 miles in 10 hours

• D.

120 miles in 15 hours

B. 85 miles in 5 hours
Explanation
The unit rate of 17 miles per hour means that for every hour, the object is traveling 17 miles. To determine which option has a unit rate of 17 miles per hour, we need to calculate the rate for each option. For 60 miles in 2 hours, the rate is 60/2 = 30 miles per hour. For 85 miles in 5 hours, the rate is 85/5 = 17 miles per hour. For 90 miles in 10 hours, the rate is 90/10 = 9 miles per hour. Finally, for 120 miles in 15 hours, the rate is 120/15 = 8 miles per hour. Therefore, the option with a unit rate of 17 miles per hour is 85 miles in 5 hours.

• C.

4m + 4

• D.

2(1 + m) + m + 6 + m

C. 4m + 4
Explanation
The expression 4m + 4 is not equivalent to the others because it does not have any terms with the coefficient of m greater than 1. The other expressions have terms with coefficients of m greater than 1, such as 3m and 2m. Therefore, 4m + 4 is the only expression that does not have this property and is not equivalent to the others.

• B.

100 + 5n

• C.

5(n + 100)

• D.

5(n â€“ 100)

B. 100 + 5n
Explanation
The expression 100 + 5n represents the cost for any number of people. The initial cost to reserve the rink is \$100, and then an additional \$5 is charged per person. By multiplying the number of people (n) by 5 and adding it to the initial cost of \$100, we get the total cost for any number of people.

### The seventh grade class is going on a trip to the state fair. The trip costs \$52. Included in that price is \$11 for a concert ticket and the cost of two passes, one for rides and one for game booths. Each of the passes cost the same price. Write an equation representing the cost of the trip and determine the price of one pass.

• A.

2x â€“ 11 = 52; \$31.50

• B.

3x = 52; \$17.33

• C.

2x = 52; \$26

• D.

52 = 11 + 2x; \$20.50

D. 52 = 11 + 2x; \$20.50
Explanation
The equation 52 = 11 + 2x represents the cost of the trip. The left side of the equation, 52, represents the total cost of the trip. The right side of the equation, 11 + 2x, represents the sum of the concert ticket cost (\$11) and the cost of two passes (2x). By solving the equation, we can determine the value of x, which represents the cost of one pass. In this case, the value of x is \$20.50.

### A rectangle has vertices P(1, 0), Q(6, 0), R(6, 6), and S(1, 6).What is the area of rectangle PQRS?

C.
Explanation
To find the area of a rectangle, we can use the formula: Area = length Ã— width. In this case, we can find the length by calculating the distance between points P and Q, which is 6 - 1 = 5 units. The width can be found by calculating the distance between points P and S, which is 6 - 0 = 6 units. Therefore, the area of rectangle PQRS is 5 Ã— 6 = 30 square units.

### Determine the surface area of rectangular prism with height 5 inches, width 7 inches, and length 12 inches.

B.
Explanation
To determine the surface area of a rectangular prism, we need to find the area of each face and then add them together. The prism has 6 faces: 2 bases and 4 lateral faces. The area of each base is equal to the length multiplied by the width, so in this case, it would be 12 inches multiplied by 7 inches. The area of each lateral face is equal to the height multiplied by the width, so it would be 5 inches multiplied by 7 inches. Adding the areas of all the faces together gives us the total surface area of the rectangular prism.

### If a rectangle, measuring 2 in. by 7 in., is enlarged by using a scale factor of 2, what will the area be of the new rectangle?

• A.

56

• B.

28

• C.

14

• D.

98

A. 56
Explanation
When a rectangle is enlarged by a scale factor of 2, both the length and width of the rectangle are multiplied by 2. In this case, the original rectangle measures 2 in. by 7 in. When we multiply both the length and width by 2, we get a new rectangle that measures 4 in. by 14 in. The area of a rectangle is calculated by multiplying the length by the width. Therefore, the area of the new rectangle is 4 in. multiplied by 14 in. which equals 56.

### Solve the following inequality. -0.5x - 5  -1.5

• A.

X   -7

• B.

X   7

• C.

X   7

• D.

X   -7

D. X   -7
Explanation
The given inequality is -0.5x - 5 â‰¤ -1.5. To solve this inequality, we can add 5 to both sides of the inequality to isolate the variable. This gives us -0.5x â‰¤ -1.5 + 5, which simplifies to -0.5x â‰¤ 3.5. Now, we can divide both sides of the inequality by -0.5, remembering to reverse the inequality sign since we are dividing by a negative number. This gives us x â‰¥ -7. Therefore, the correct answer is x â‰¥ -7.

### The Irrational Club wants to build a tree house. They have a 13-foot ladder that must be propped diagonally against the tree. If the base of the ladder is 5 feet from the bottom of the tree, how high will the tree house be off the ground?

• A.

12 feet

• B.

144 feet

• C.

169 feet

• D.

14 feet

A. 12 feet
Explanation
The height of the tree house can be determined using the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (the ladder) is equal to the sum of the squares of the other two sides. In this case, the ladder is the hypotenuse, and the base of the ladder is one side of the triangle. The other side represents the height of the tree house. Using the given information, we can calculate the height as follows: (5^2) + (x^2) = (13^2). Solving for x, we find that the height of the tree house is 12 feet.

### What table of ordered pairs corresponds to the function y =  -3x + 1?

C.
Explanation
The table of ordered pairs corresponds to the function y = -3x + 1 can be generated by substituting different values of x into the equation and solving for y. The x-values can be chosen arbitrarily, and then the corresponding y-values can be calculated using the equation. For example, if we choose x = 0, then y = 1. If we choose x = 1, then y = -2. By continuing this process, we can generate a table of ordered pairs that corresponds to the given function.

### Write the equation of a line, in slope-intercept form, passing through the points (6, 2) and (3, 0).

A.
Explanation
To find the equation of a line in slope-intercept form, we need to determine the slope and the y-intercept. The slope can be found using the formula: slope = (change in y) / (change in x). By substituting the coordinates of the two points, we can calculate the slope as (0 - 2) / (3 - 6) = -2/3. The y-intercept can be found by substituting the coordinates of one of the points into the equation y = mx + b, where m is the slope. Using the point (6, 2), we can substitute the values to find the y-intercept: 2 = (-2/3)(6) + b. Solving for b, we get b = 6. Therefore, the equation of the line is y = (-2/3)x + 6.

Rate this question:

• 35.

### Which is the graph of the function y = 4x – 1?
