If four apples cost 20 cents, then the cost of each apple is 20 cents divided by 4, which is 5 cents. To find the cost of ten apples, we multiply the cost of one apple (5 cents) by ten, which gives us 50 cents. Therefore, ten apples would cost $.50.

If y% of 50 is 32, it means that y is equal to 64. To find 200% of y, we multiply y by 2, which gives us 128. Therefore, the answer is 128.

The given sequence consists of three repeating terms: -1, 1, and 2. The sum of these three terms is 2. Since there are 25 terms in total, we can divide 25 by 3 to find the number of complete repetitions of the sequence, which is 8. Therefore, the sum of the first 24 terms (8 complete repetitions) is 8 multiplied by 2, which equals 16. Finally, adding the 25th term, which is -1, to the sum gives us a total of 15.

The area of a right triangle is given by the formula (1/2) * base * height. In this case, we are given that the area is 10 square centimeters. Since both the base and height are positive integers, we need to find two integers that multiply to give 20. The possible pairs of integers are (1, 20), (2, 10), and (4, 5). Using the Pythagorean theorem, we can calculate the length of the hypotenuse for each pair. The pair (4, 5) gives us a hypotenuse length of the square root of 41, which is the smallest possible length among the given options.

The equation m/n = 8 implies that m = 8n. Substituting this into the inequality 0

The probability of choosing a white marble from the jar at random is 1/4. Since the ratio of white marbles to blue marbles is 4 to b, this means that out of every 4 + b marbles, 4 are white. Therefore, the value of b must be 12 in order for the probability of choosing a white marble to be 1/4.

When y is a number less than 0 but greater than -1, y^2 will always be positive because squaring a negative number gives a positive result. On the other hand, 100y will be negative since y is negative. Since y^2 is positive and 100y is negative, y^2 will have the greatest value among the given expressions.

If the first day of the month is Tuesday, and there are 31 days in the month, then we can count that there are 4 complete weeks in the month. Since each week has 7 days, we subtract 28 days from the 31st day, which leaves us with 3 remaining days. Therefore, the 31st day of the month will be three days after Tuesday, which is Thursday.

The volume of a cylinder is directly proportional to the square of its radius and its height. Since the volume of cylinder A is twice the volume of cylinder B, and the height of cylinder B is twice the height of cylinder A, we can set up the following equation: (πrA^2)(2hA) = (πrB^2)(hB). Simplifying this equation, we get rA^2 * 2 = rB^2 * 1. Since the height ratio is not mentioned, we can assume it cancels out. Therefore, the ratio of the radius of cylinder A to the radius of cylinder B is 2 to 1.

Since every number in the set is even and/or a multiple of 3, the numbers that are both even and multiples of 3 are multiples of 6. We are given that there are 22 even numbers and 15 multiples of 3. However, some of these numbers may be counted twice since they can be both even and multiples of 3. To find the number of multiples of 6, we need to subtract the overlap. The overlap can be found by taking the smaller number, which is 15 in this case. Therefore, the number of multiples of 6 is 15 - (22 - 15) = 7.

If no fuzzle is lumpy, then no wuzzle is grumpy. This can be inferred from the original statement. If at least one wuzzle is grumpy, then some fuzzles are lumpy. Therefore, if no fuzzles are lumpy, it means that there are no grumpy wuzzles.
