HESI A2 Math

Correct Answer: B

Rationale: To find the total feed weight, we multiply the weight of one bag by the number of bags. 50 kg x 3 bags = 150 kg. Therefore, the correct answer is B (150 kilograms). Option A (100 kg) is incorrect as it represents the weight of 2 bags only. Option C (200 kg) and Option D (250 kg) are incorrect as they miscalculate the total weight by either adding or multiplying the weights incorrectly.

Correct Answer: A

Rationale: To find the area of a rectangle, you multiply its length by its width. In this case, the length is 12 meters and the width is 10 meters. So, Area = Length x Width = 12m x 10m = 120 square meters. Choice A is correct as it correctly calculates the area. Choices B, C, and D are incorrect as they do not correctly calculate the area based on the given dimensions.

Correct Answer: A

Rationale: To find Andy's daily mileage, we first calculate Jake's daily mileage: 24.5 miles / 7 days = 3.5 miles/day. Since Andy runs five times as much, he runs 3.5 * 5 = 17.5 miles/day. Therefore, the correct answer is A. Choice B (17.7) is incorrect because it is not the result of the calculation in this scenario. Choice C (16.5) is incorrect as it does not account for Andy running five times as much as Jake. Choice D (18.2) is incorrect because it does not align with the correct calculation based on the information provided.

Correct Answer: B

Rationale: To calculate the interest earned on a principal of $1,000 with a 5% annual interest rate, you multiply the principal by the interest rate: $1,000 x 0.05 = $50. Therefore, the correct answer is B, $50. Choice A is incorrect as it miscalculates the interest. Choice C overestimates the interest earned. Choice D is close, but $55 is not the correct calculation based on the given information.

Correct Answer: A

Rationale: To convert grams to pounds, divide the weight in grams by 453.592 (1 pound is approximately equal to 453.592 grams). Therefore, to convert 1,500 grams to pounds, you would do 1500 / 453.592 = 3.30693393, which rounds down to 3.3 pounds (Answer A). The other choices are incorrect as they do not provide the accurate conversion from grams to pounds. Answer A is the correct choice as it is the result of the precise calculation.
