Math HESI A2 Practice Test

Correct Answer: A

Rationale: To find the rate of calories burned per mile, divide the total calories burned (2276) by the total miles ran (21.4). So, 2276 / 21.4 = 106.4. This means the runner burns approximately 106.4 calories per mile. Choice A (106.4) is correct as it represents the correct calculation result. Choices B, C, and D are incorrect as they do not match the calculated value based on the given information.

Correct Answer: B

Rationale: The correct answer is B (2.8 liters) because 1 quart is equivalent to 0.946 liters. Therefore, 3 quarts would be 3 * 0.946 = 2.838 liters, which is closest to 2.8 liters. Choice A (3.0 liters) is incorrect because it does not accurately convert quarts to liters. Choice C (2.5 liters) is incorrect as it underestimates the conversion. Choice D (3.5 liters) is incorrect as it overestimates the conversion. The most accurate conversion is 2.8 liters, making it the correct answer.

Correct Answer: A

Rationale: To calculate 54% of $789.56, you multiply 789.56 by 0.54. This gives you $426.36, which is option A. The correct answer is A because multiplying the percentage (54%) by the total amount ($789.56) gives the accurate result. Option B, $426.37, is incorrect as it is a slightly higher amount due to rounding off. Option C, $363.20, and option D, $526.38, are incorrect because they are not the result of calculating 54% of $789.56 accurately.

Correct Answer: D

Rationale: To solve x/5 = 3/10, first cross multiply to get 10x = 15. Then divide both sides by 10 to isolate x, giving x = 1.5. This is the correct answer as it satisfies the original equation. Choices A, B, and C are incorrect as they do not match the result obtained from solving the equation step by step.

Correct Answer: A

Rationale: To find the result of subtracting 4.7 from 9.5, we need to subtract 4.7 from 9.5. This can be calculated as 9.5 - 4.7 = 4.8. Therefore, the correct answer is A. Choice B (4.9) is incorrect because it is not the result of the subtraction operation provided in the question. Choice C (4.6) is incorrect because it is the result of subtracting 5.1 from 9.7, not 4.7 from 9.5. Choice D (4.7) is incorrect because it is the number being subtracted and not the final result of the subtraction.
