HESI A2 Math Practice Test 2024

Correct Answer: D

Rationale: To calculate the total days off, add Bill's remaining vacation days (2.5) and sick days (1.25): 2.5 + 1.25 = 3.75 days. Since Bill is using all his sick days and vacation days, he will have 3 full days off work. Therefore, the correct answer is D (4 days). Choices A, B, and C are incorrect as they do not consider the combination of remaining days and assume a different outcome.

Correct Answer: A

Rationale: Step-by-step rationale: 1. An even number is divisible by 2. 2. 12 is divisible by 2 (12 ÷ 2 = 6). 3. Therefore, 12 is an even number (Choice A). Summary: B: Incorrect - Odd numbers are not divisible by 2. C: Incorrect - Prime numbers have only 2 factors. D: Incorrect - Composite numbers have more than two factors.

Correct Answer: A

Rationale: To find the correct answer, we need to set up a proportion: 4 cups of sugar for 120 cookies is equivalent to x cups of sugar for 90 cookies. Cross multiply to get 4*90 = 120*x, which simplifies to 360 = 120x. Divide by 120 to get x = 3 cups. Therefore, the correct answer is A: 3 cups of sugar. The other choices are incorrect because they do not align with the proportional relationship between the amount of sugar and the number of cookies in the recipe. Choice B, 2 cups, is too few as it would be for fewer than 90 cookies. Choice C, 1.5 cups, is even less than 2 cups and doesn't fit the ratio. Choice D, 4 cups, is the amount needed for 120 cookies, not 90.

Correct Answer: A

Rationale: The nurse's schedule rotates every 4 days, working 3 days and having 1 day off. If the first day off is Monday, the next day off will be on the 4th day, which is Friday. The pattern is: Work - Work - Work - Off. Therefore, the correct answer is A: Friday. Other choices are incorrect because the pattern of the nurse's schedule clearly indicates that the second day off falls on the 4th day, which is Friday in this case.

Correct Answer: B

Rationale: To convert milligrams to grams, divide by 1000 since 1 gram = 1000 milligrams. 150 milligrams ÷ 1000 = 0.15 grams. Therefore, the correct answer is B. Explanation for other choices: A: 0.015 grams = Incorrect, a decimal point is missing. C: 1.5 grams = Incorrect, this would be the result if the milligrams were converted to grams as if they were micrograms. D: 15 grams = Incorrect, this would be the result if the milligrams were mistakenly multiplied by 100 instead of divided by 1000.
