Math HESI A2 Practice Test

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 subtract 9.99 from 12.02, we need to align the decimal points. 12.02 minus 9.99 equals 2.03. So, the correct answer is A. Choice B, 2.21, is the result of adding the numbers. Choice C, 3.17, is the result of adding 9.99 and 2.03. Choice D, 7.97, is the result of subtracting 12.02 from 9.99.

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: B

Rationale: To express 0.75 as a fraction, first note that 0.75 is equivalent to 75/100. Simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 25, gives 3/4. Therefore, the correct answer is B: 3/4. Option A (4/5) is incorrect as it does not represent 0.75. Option C (1/2) is incorrect as it is not equal to 0.75. Option D (1/4) is incorrect as it is not the equivalent fraction of 0.75.

Correct Answer: A

Rationale: To calculate the profit, we first find the total cost of cultivation: 240 acres * $188.99/acre = $45,357.60. Then, we find the total revenue from selling the yield: 240 acres * 60 bushels/acre * $5.67/bushel = $81,648. Finally, we subtract the cost from the revenue to get the profit: $81,648 - $45,357.60 = $36,290.40. Therefore, the correct answer is A. Choice B is incorrect because it miscalculates the profit by not subtracting the cost from the revenue. Choice C is incorrect as it overestimates the profit. Choice D is incorrect as it is not the accurate profit value based on the given information.
