HESI A2 Math Practice Exam

Correct Answer: B

Rationale: To find the total number of games played, we divide the number of games won (72) by the percentage of games won (90%). This gives us 72 / 0.90 = 80 games played. Therefore, choice B is correct. Choice A (75) is incorrect because it does not account for the percentage of games won. Choice C (85) is incorrect as it overestimates the total number of games played. Choice D (100) is incorrect as it does not reflect the fact that the team won only 90% of the games played.

Correct Answer: B

Rationale: To find the total number of staff working, calculate 68% of the total staff. Total staff = 25 (RN) + 75 (assistants) + 5 (phlebotomists) + 6 (receptionists) + 45 (physicians) = 156 68% of 156 = 0.68 x 156 = 106.08 Rounded to the nearest whole number, the total staff working that day is 106. Therefore, the correct answer is B: 106. Summary: A: 102 - Incorrect, not the nearest whole number. C: 98 - Incorrect, below the calculated total. D: 110 - Incorrect, above the calculated total.

Correct Answer: A

Rationale: To convert ounces to pints, we know that 1 pint is equal to 16 ounces. Therefore, to find how many pints are in 56 ounces, we divide 56 by 16. 56 ÷ 16 = 3.5 pints. So, the correct answer is A: 3.5 pints. Choices B, C, and D are incorrect because they do not accurately represent the conversion of 56 ounces to pints based on the conversion factor of 1 pint = 16 ounces.

Correct Answer: D

Rationale: The correct answer is D: 16. A perfect square is a number that can be expressed as the product of an integer multiplied by itself. In this case, 16 is a perfect square because it can be written as 4 x 4. Choices A, B, and C are not perfect squares because they cannot be expressed as the product of an integer multiplied by itself. Thus, 16 is the only number among the choices that fits the definition of a perfect square.
