HESI A2 Math Practice Exam

Correct Answer: B

Rationale: To convert inches to feet, divide the number of inches by 12 since there are 12 inches in a foot. 72 inches divided by 12 equals 6 feet. Therefore, the correct answer is B: 6 feet. Choice A (12 feet) is incorrect as it is the conversion of 144 inches, not 72 inches. Choice C (4 feet) and Choice D (17 feet) are also incorrect as they do not accurately represent the conversion of 72 inches to feet.

Correct Answer: C

Correct Answer: A

Rationale: Certainly! To compare, we need to convert both fractions to a common denominator. LCM of 8 and 100 (8*25) is 100. Sally ate (5/8)*100 = 62.5%. John ate 75%. Clearly, 75% is more than 62.5%. So, John ate more. Other choices are incorrect as they do not consider the actual percentages consumed by Sally and John.

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.

Correct Answer: C

Rationale: To find the number of customers served, we add the incidents that delayed the server's service time: 43 customers + 2 broken glasses + 5 slips = 50 incidents Given that the server breaks 10 glasses the next day, we double the incidents: 50 incidents x 2 = 100 incidents Each incident corresponds to serving a customer, so the server served 100 customers in total. Thus, the correct answer is C (86 customers). Choices A, B, and D are incorrect because they do not account for the additional incidents affecting the service time.
