Correct Answer: C

Rationale: The correct answer is C: 8 pints. There are 8 pints in a gallon because 1 gallon is equivalent to 8 pints. This conversion is based on the fact that a gallon is defined as 128 fluid ounces and a pint is 16 fluid ounces, so 128/16 = 8 pints in a gallon. Choice A (2 pints) is incorrect because it does not correspond to the correct conversion. Choice B (4 pints) is incorrect as it is half of the correct answer. Choice D (16 pints) is incorrect as it represents the total number of fluid ounces in a gallon, not the number of pints.

Correct Answer: A

Rationale: The correct answer is A: y = 3x. To find the relationship between x and y, we can observe that y is always 3 times the value of x in each row. For example, when x = 2, y = 6 (6 = 3 * 2). This pattern holds true for all data points provided. Therefore, the correct equation is y = 3x. Choice B (x = 3y) is incorrect because it suggests that x is 3 times the value of y, which is not the case based on the given data. Choice C (y = x/3) is incorrect as it implies that y is one-third of x, which does not match the relationship shown in the table. Choice D (y = x + 3) is incorrect as it simply adds 3 to x to get y, which is not consistent with the provided data points.

Correct Answer: B

Rationale: To find the total height when stacked, we add the heights of the two bookcases. 32.75 inches + 17.25 inches = 50 inches Therefore, the correct answer is B (50 inches). Explanation for incorrect choices: A: 49.5 inches is incorrect because the heights are added, not averaged. C: 48 inches is incorrect as it's less than the sum of the two heights. D: 51 inches is incorrect as it's greater than the sum of the two heights.

Correct Answer: B

Rationale: The correct answer is B: 5,280 ft. There are 5,280 feet in a mile because a mile is defined as 5,280 feet. This standard measurement is widely accepted in the United States. The other choices (A, C, D) are incorrect because they do not correspond to the precise conversion factor for a mile. Choice A (1,000 ft) is too small, Choice C (2,000 ft) is also too small, and Choice D (10,000 ft) is too large. Therefore, B is the correct answer as it accurately reflects the established conversion of feet in a mile.

Correct Answer: D

Rationale: The correct answer is D: 4 quarts. There are 4 quarts in a gallon. This is because a gallon is a unit of volume equal to 128 fluid ounces, and each quart is equal to 32 fluid ounces. Therefore, to find out how many quarts are in a gallon, you divide the total number of fluid ounces in a gallon by the number of fluid ounces in a quart (128 ÷ 32 = 4). Choice A (1 quart) is incorrect because a quart is smaller than a gallon. Choice B (2 quarts) is incorrect as it is half of the correct amount. Choice C (3 quarts) is also incorrect as it is three-quarters of the correct amount. The correct answer is D (4 quarts) because it accurately represents the conversion of fluid ounces from gallons to quarts.
