Correct Answer: B

Rationale: To calculate average speed, you divide the total distance by the total time. In this case, 150 miles divided by 3 hours equals 50 mph. Therefore, choice B is correct. Choice A is incorrect as it is too low. Choice C and D are incorrect as they are too high.

Correct Answer: D

Rationale: To find the number of nights Sarah needs to read 140 pages, we first calculate her rate: 21 pages / 4 nights = 5.25 pages/night. Then, we divide 140 pages by her rate: 140 pages / 5.25 pages/night ≈ 26.67 nights. Since she can't read a fraction of a night, she would need 27 nights to read 140 pages. A: Incorrect. 6 nights is too short based on the rate calculation. B: Incorrect. 26 nights is close, but rounding up is necessary. C: Incorrect. 8 nights is too short based on the rate calculation.

Correct Answer: B

Rationale: To round 89632 to the nearest hundred, we look at the digit in the hundreds place, which is 6. Since 6 is greater than or equal to 5, we round up the hundreds place to the next hundred, making it 900. The correct answer is B. Choice A: 847.9 - Incorrect. This is not a correct rounding of 89632 to the nearest hundred. Choice C: 847.89 - Incorrect. This answer is not related to the rounding of 89632 to the nearest hundred. Choice D: 847.896 - Incorrect. This answer is not related to the rounding of 89632 to the nearest hundred.

Correct Answer: B

Rationale: To maintain an overall average of at least 90, Dwayne needs to aim for the highest possible score. If he scores 98 on his next test, it will help balance any lower scores he may have received previously and ensure his average remains above 90. Choosing option B (98) is the best strategy as it allows for a margin of error while still meeting the target average. Options A, C, and D would not guarantee maintaining the required average as they are below 90.

Correct Answer: C

Rationale: The correct answer is C (4). Sarah buys one red can of paint every month for four months. So, she buys 1 can each month, totaling 4 cans over 4 months. To find the total number of cans, we add 1 + 1 + 1 + 1 = 4. Therefore, Sarah bought 4 red cans in total. Choices A, B, and D are incorrect because they do not accurately reflect the total number of cans Sarah bought. Choice A (2) is incorrect because it only represents half of the cans she actually bought. Choice B (3) is incorrect because it does not account for the full four months. Choice D (5) is incorrect because it overestimates the number of cans purchased.
