HESI A2 Math Practice Exam

Correct Answer: C

Rationale: To convert 5 3/4 to a decimal, first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. Rounding to the nearest tenth gives 5.8, which is choice C. Choices A, B, and D are incorrect because they do not accurately represent the decimal equivalent of 5 3/4 rounded to the nearest tenth.

Correct Answer: B

Rationale: The correct answer is B: $19.60. To calculate profit, we subtract the distribution cost from the total revenue. If the distribution cost is $10, and profit is the remainder, then profit = total revenue - distribution cost. Let's denote total revenue as TR. Therefore, profit = TR - $10. Since the distribution cost is $10, the profit will be TR - $10. To find TR, we add the distribution cost to the profit: TR = profit + $10. If we substitute $10 for the distribution cost and $19.60 for profit, we get TR = $19.60 + $10 = $29.60. This means that the correct answer for the profit will be $19.60. Summary: A: $10.40 - Incorrect. This choice is lower than the distribution cost, so it cannot be the profit. C: $14.90 - Incorrect. This choice is also lower than the distribution cost, ruling

Correct Answer: A

Rationale: To find the total days off work, we add Bill's remaining vacation days (5.5) and sick days (3.25). 5.5 + 3.25 = 8.75 Therefore, Bill will have 8.75 days off work if he uses all of his remaining vacation and sick days. Choice A (8.75) is correct because it accurately represents the total days off. Choices B, C, and D are incorrect as they do not correctly calculate the total days off based on the given information.

Correct Answer: A

Rationale: The correct answer is A: 1,760 yards in a mile. This is because 1 mile is equal to 1,760 yards. To convert miles to yards, you multiply the number of miles by 1,760. The other choices (B, C, D) are incorrect as they do not represent the accurate conversion factor for miles to yards. Option B (1,700) is too low, option C (1,800) is too high, and option D (1,750) is also incorrect. Therefore, the correct answer is A, 1,760 yards in a mile.

Correct Answer: A

Rationale: To find the number of days to use 500 labels, first calculate the total labels used daily: 25 boxes/day * 3 labels/box = 75 labels/day. Then, divide the total labels (500) by labels used per day (75): 500 / 75 = 6.67 days. Since we need to round to the nearest whole number, it will take 7 days (Answer A) to use up the inventory. Choice B is incorrect as it doesn't account for rounding. Choice C is incorrect as it overestimates the number of days. Choice D is incorrect as it underestimates the number of days.
