The word "superstar" has 9 letters. Out of these 9 letters, there are 3 vowels (u, e, a). Therefore, the probability of randomly choosing a vowel from the word "superstar" is 3/9, which simplifies to 1/3.

Since half of the basketball court is an exact square, we can determine the length of one side of the square by dividing the length of the court by 2. Therefore, the length of one side of the square is 100ft / 2 = 50ft. The area of a square is calculated by multiplying the length of one side by itself, so the area of the square is 50ft * 50ft = 2500 sqft. Therefore, the area of one half-court is 2500 sqft.

In a regular deck of 52 cards, there are 12 face cards (4 jacks, 4 queens, and 4 kings). The probability of picking a face card from a regular deck can be calculated by dividing the number of face cards by the total number of cards in the deck. Therefore, the probability is 12/52, which simplifies to 3/13.

The volume of a cube is calculated by multiplying the length, width, and height of the cube. In this case, the volume is given as 125cm3. Since all sides of a cube are equal, we can find the length of one side by taking the cube root of the volume. The cube root of 125 is 5. Therefore, the length of one side of the cube is 5cm. The area of one face of the cube is found by squaring the length of one side. The square of 5 is 25. Therefore, the area of one face of the cube is 25 sqcm.

The sum of the first five terms of a geometric sequence can be found using the formula S = a(r^n - 1) / (r - 1), where S is the sum, a is the first term, r is the common ratio, and n is the number of terms. In this case, we are given that S = 93, r = 2, and n = 5. Plugging these values into the formula, we can solve for a.

The bus fare for the first 5 km is P20.00. For every additional kilometer after the first 5 km, the fare is P3.50. Since the bus trip is 45 km, we need to calculate the fare for the additional 40 km. 40 km multiplied by P3.50 gives us P140.00. Adding this to the initial fare of P20.00, we get a total fare of P160.00.

When rolling a pair of 6-sided dice, there are a total of 36 possible outcomes (6 outcomes for the first die multiplied by 6 outcomes for the second die). To get a sum of 10, there are only 3 possible outcomes: (4,6), (5,5), and (6,4). Therefore, the probability of getting a sum of 10 is 3/36, which simplifies to 1/12.

.

The probability of getting a ball divisible by 6 can be calculated by finding the number of balls divisible by 6 and dividing it by the total number of balls. In this case, there are 16 balls (6, 12, 18, ..., 96, 100) that are divisible by 6, out of a total of 100 balls. Therefore, the probability is 16/100, which simplifies to 4/25.

In a geometric progression, each term is obtained by multiplying the previous term by a constant called the common ratio. In this case, we can find the common ratio by dividing the fifth term (162) by the second term (6). 162 divided by 6 equals 27. Therefore, the common ratio is 27.

The x-intercept of a line is the point where the line crosses the x-axis. To find the x-intercept, we set y=0 in the equation of the line and solve for x. In this case, when we substitute y=0 into the equation 2x + 7y + 15 = 0, we get 2x + 15 = 0. Solving for x, we find x = -15/2. Therefore, the x-intercept of the line is -15/2.

There are four students and four chairs, so the first student has four choices for a seat. After the first student is seated, there are three remaining seats for the second student to choose from. Once the second student is seated, there are two remaining seats for the third student, and finally, the last student has only one seat left to choose from. Therefore, the total number of ways the four students can sit in a row of four chairs is 4 x 3 x 2 x 1 = 24.

The maximum rectangular area that can be enclosed in a wire of length 8m is 4 sqm. This can be achieved by creating a square with sides measuring 2m each. The perimeter of this square would be 8m, and the area would be 4 sqm.

A regular pentagon has five equal sides and five equal interior angles. To find the measure of an interior angle, we can use the formula (n-2) * 180 / n, where n is the number of sides of the polygon. Plugging in the values, we get (5-2) * 180 / 5 = 3 * 180 / 5 = 540 / 5 = 108 degrees. Therefore, the measure of an interior angle of a regular pentagon is 108 degrees.

The sum of the first 40 multiples of 4 can be found by using the formula for the sum of an arithmetic series. The formula is given by S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, the first term is 4 and the last term is 160. Plugging these values into the formula, we get S = (40/2)(4 + 160) = 20(164) = 3280. Therefore, the correct answer is 3280.

To find the number of 3-digit numbers that can be formed without repeating the digits, we need to calculate the number of permutations. We have 5 digits to choose from for the hundreds place, 4 digits for the tens place (as one digit has already been used), and 3 digits for the units place. Therefore, the total number of permutations is 5 x 4 x 3 = 60. Hence, the correct answer is 60.

To find the remainder when the sum of twelve consecutive integers is divided by 4, we can start by denoting the first integer as n. The twelve consecutive integers would then be:

n, n+1, n+2, n+3, n+4, n+5, n+6, n+7, n+8, n+9, n+10, n+11

Next, we can calculate the sum of these integers:

Sum = n + (n+1) + (n+2) + (n+3) + (n+4) + (n+5) + (n+6) + (n+7) + (n+8) + (n+9) + (n+10) + (n+11)

This simplifies to:

Sum = 12n + (0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11)

The sum of the integers from 0 to 11 is:

0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 = 66

So, we can rewrite the total sum:

Sum = 12n + 66

Next, we need to find the remainder of this sum when divided by 4. To do that, we will evaluate each part of the expression modulo 4.

12n mod 4: Since 12 is a multiple of 4, 12n mod 4 = 0 for any integer n.

66 mod 4: Now we calculate the remainder of 66 when divided by 4:

66 divided by 4 equals 16.5 (the integer part is 16)

16 times 4 equals 64

66 minus 64 equals 2

Thus, 66 mod 4 = 2.

Now, combining the two parts:

(12n + 66) mod 4 = (0 + 2) mod 4 = 2

Therefore, the remainder when the sum of twelve consecutive integers is divided by 4 is:

The original price of calamansi was 8 for P2.00, which means each calamansi cost P0.25. After the price change, the new price is 10 calamansi for P3.00, which means each calamansi now costs P0.30. To find the percent increase, we calculate the difference between the new and old prices, which is P0.30 - P0.25 = P0.05. Then we divide this difference by the old price, P0.05 / P0.25 = 0.2. Finally, we multiply this result by 100 to find the percentage increase, 0.2 * 100 = 20%.

When two coins are tossed, each coin has two possible outcomes: heads or tails. Since we are interested in the probability of getting tails on both coins, we need to consider the probability of getting tails on the first coin (1/2) multiplied by the probability of getting tails on the second coin (1/2). Multiplying these probabilities gives us 1/4, which is the probability of getting tails on both coins.

The given statement does not provide enough information to determine the relationship between x and z. Therefore, none of the options can be definitively concluded based on the given information.

The statement "none of the above" is not true because all of the statements given are true. The slope of a vertical line is undefined because it does not have a defined rise over run. The slope of a line from left to right, going upwards is positive because it has a positive rise over run. The slope of a line from left to right, going downwards is negative because it has a negative rise over run. Therefore, all of the statements given are true.

When the height of a triangle is halved and its base is doubled, the area of the new triangle remains the same as the area of the old one. This is because the formula for the area of a triangle is 1/2 * base * height. When the height is halved, the factor of 1/2 is compensated by doubling the base, resulting in the same area. Therefore, the ratio of the area of the new triangle to the area of the old one is 1:1.

To find the sale price of a can with a 10% profit, we need to calculate the cost price of the can. Since the supermarket makes a 40% profit when selling the can at P16.80, the cost price can be calculated as follows:

Cost Price = Selling Price / (1 + Profit %)
Cost Price = P16.80 / (1 + 40/100)
Cost Price = P16.80 / 1.40
Cost Price = P12

Now, to make a 10% profit, we can calculate the sale price as follows:

Sale Price = Cost Price + (Cost Price * Profit %)
Sale Price = P12 + (P12 * 10/100)
Sale Price = P12 + P1.20
Sale Price = P13.20

Therefore, the sale price of a can should be P13.20.

We have a right triangle with sides of 2 inches and 9 inches, and we’re solving for the hypotenuse, which is the radius of the table.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as:

a²+b²=c²

In this case, a is 2 inches, b is 9 inches, and c is the radius of the table we’re trying to find.

So, we can set up the equation as follows:

22+92=r²

4+81=r²

85=r²

Taking the square root of both sides to solve for r gives us:

√r²=√85​

To get the decimal approximation of the square root of 85, we can use a calculator. The square root of 85 is approximately 9.219544457292887.

So, when rounded to two decimal places, the radius of the table is approximately 9.22 inches.

The minute hand of a clock makes one complete revolution every 60 minutes. Since it has made sixteen complete revolutions since noon, it means that 16 hours have passed. The hour hand moves 30 degrees per hour, so in 16 hours, it has moved 16 * 30 = 480 degrees. The minute hand moves 360 degrees in one complete revolution. Since the hour hand is at 480 degrees and the minute hand has made 16 complete revolutions, it means that the minute hand is at 480 + (16 * 360) = 6120 degrees. The angle between the minute hand and the hour hand is the difference between their positions, so it is 6120 - 480 = 5640 degrees. However, we only need to consider the angle within one complete revolution, so we subtract 360 degrees from 5640, resulting in 5280 degrees. Finally, we subtract 5280 degrees from 6120 degrees to find the angle between the minute hand and the hour hand, which is 6120 - 5280 = 840 degrees. However, we only need to consider the smaller angle within one complete revolution, so we subtract 360 degrees from 840, resulting in 480 degrees. Therefore, the angle the minute hand makes with the hour hand is 480 degrees.

The total surface area of a rectangular solid can be found by adding up the areas of all six faces. In this case, the length is 7 meters, the width is 6 meters, and the depth is 3 meters. The formula for the surface area of a rectangular solid is 2lw + 2lh + 2wh. Plugging in the given values, we get 2(7)(6) + 2(7)(3) + 2(6)(3) = 84 + 42 + 36 = 162 square meters.

Let's assume the length of the rectangle is L. According to the given information, the width of the rectangle is 4/5 of its length, which means the width is (4/5)L.
The perimeter of a rectangle is given by the formula P = 2(L + W), where P is the perimeter, L is the length, and W is the width.
Substituting the given values, we have 72 = 2(L + (4/5)L).
Simplifying the equation, we get 72 = 2(9/5)L.
Dividing both sides by 2, we get 36 = (9/5)L.
Multiplying both sides by 5/9, we get L = 20.
Therefore, the length of the rectangle is 20 units and the width is (4/5)(20) = 16 units.
The area of a rectangle is given by the formula A = L * W.
Substituting the values, we get A = 20 * 16 = 320.
Hence, the area of the rectangle is 320.

The car first traveled 3 miles south, then 9 miles east, and finally another 9 miles south. If we draw a straight line from the starting point to the stopping point, it would form a right-angled triangle. The distance traveled south can be considered as the height of the triangle, which is 3 + 9 = 12 miles. The distance traveled east can be considered as the base of the triangle, which is 9 miles. Using the Pythagorean theorem, we can calculate the hypotenuse (the straight-line distance) as the square root of (12^2 + 9^2) = 15 miles. Therefore, the correct answer is 15.

When the radius of a circle is increased by 30%, the new radius becomes 1.3 times the original radius. The area of a circle is calculated using the formula A = πr^2, where r is the radius. If we substitute the new radius into the formula, we get A' = π(1.3r)^2 = π(1.69r^2). Comparing this to the original area, the area increase is 69% (1.69 - 1 = 0.69 or 69%).
