HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To convert centimeters to inches, we use the conversion factor 1 inch = 2.54 centimeters. Therefore, to convert 65.4 centimeters to inches, we divide 65.4 by 2.54. The calculation is 65.4 / 2.54 = 25.74 inches. This is why choice A (25.74) is correct. Choices B, C, and D are incorrect as they do not correctly convert centimeters to inches.

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 calculate the total number of people working that day, we need to find 68% of the total staff. First, calculate 68% of each category: - Registered nurses: 25 * 0.68 = 17 - Unlicensed assistants: 75 * 0.68 = 51 - Phlebotomists: 5 * 0.68 = 3 - Receptionists and office staff: 6 * 0.68 = 4 - Physicians: 45 * 0.68 = 31 Add these numbers together: 17 + 51 + 3 + 4 + 31 = 106 people (Option A). This is the correct answer as it represents 68% of the total staff. Other options are incorrect as they do not accurately represent 68% of the total staff.

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: To convert a decimal to a percent, you multiply by 100. In this case, 0.09 * 100 = 9%. Therefore, the correct answer is A: 9%. Choice B (90%) is incorrect as it would be the result of multiplying by 1000, not 100. Choice C (1%) is incorrect as it would be the result of moving the decimal point two places to the right without multiplying by 100. Choice D (0%) is incorrect as the number is not zero, it's 0.09.
