Correct Answer: D

Rationale: To solve the equation (5/4)x = 20, we first multiply both sides by 4/5 to isolate x. So, x = 20 * 4/5 = 16. Therefore, the correct answer is D. Option A, 8, is incorrect because x is not equal to 8. Option B, 24, and option C, 32, are also incorrect as they do not satisfy the given equation.

Correct Answer: C

Rationale: To calculate the total cost: 1. Convert all weights to kilograms: - Apples: 1.2 kg - Bananas: 0.8 kg - Strawberries: 0.3 kg 2. Calculate the total weight: 1.2 + 0.8 + 0.3 = 2.3 kg 3. Multiply total weight by the flat rate: 2.3 kg x $4/kg = $9.20 Therefore, the correct answer is C: $9.20. Other choices are incorrect because they do not follow the correct calculation based on the flat rate per kilogram.

Correct Answer: C

Rationale: To find the total potential savings, we first calculate the 20% discount on the car price: 20% of $26,580 = $5,316. Next, we calculate the total monthly payments saved: 3 payments x $250 = $750. Adding the discount and saved payments gives us a total potential savings of $5,316 + $750 = $6,066. Therefore, choice C is correct. Choice A is incorrect because it does not account for the monthly payments saved. Choice B is incorrect as it only considers the discount on the car price, ignoring the saved payments. Choice D is incorrect as it overestimates the savings by combining the discount and payments saved twice.

Correct Answer: A

Rationale: To find the diameter of a circle from its circumference, we use the formula: Diameter = Circumference / π. Given the circumference is 49 feet, we can calculate the diameter by dividing 49 by π (approximately 3.14), resulting in 15.6 feet, which is choice A. Option B, 17.8 feet, is incorrect as it does not match the calculation. Option C, 49 feet, is the circumference, not the diameter. Option D, 153.9 feet, is incorrect as it is not the result of dividing the circumference by π. Therefore, choice A is the correct answer based on the formula for finding the diameter of a circle.

Correct Answer: D

Rationale: The correct answer is D: The median is less than the mean. To find the median, first arrange the set in ascending order {5, 11, 18, 20, 37, 37, 60, 72, 90}. The median is the middle value, which is 37 here. To find the mean, add up all numbers and divide by the total count (sum/9). The mean is (60+5+18+20+37+37+11+90+72)/9 = 41.67. Since 37 (median) is less than 41.67 (mean), the statement is true. Other choices are incorrect because A is false as median ≠ mean, B is false since mean > mode, and C is false since mode ≠ median.
