Math HESI A2 Practice Test

Correct Answer: A

Rationale: To calculate average speed, divide total distance by total time. In this case, 5 miles in 45 minutes equals 5/0.75 = 6.67 mph. Choice A is correct because it correctly calculates the average speed based on the given information. Choices B, C, and D are incorrect as they do not accurately calculate the average speed.

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: D

Rationale: To find 75% of 80, you multiply 80 by 0.75 (which represents 75%). 80 * 0.75 = 60. Therefore, the correct answer is D: 60. Choice A (35) is incorrect because it is not 75% of 80. Choice B (45) is also incorrect as it is not the correct calculation for 75% of 80. Choice C (70) is incorrect as well since it does not represent 75% of 80.

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: 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.
