HESI A2 Math Practice Exam

Correct Answer: A

Rationale: To calculate the nurse's take-home pay, we need to first calculate the total earnings for the week: Total earnings = (Hourly rate x total hours) = ($17.81 x (3 x 8 + 1 x 12)) = $17.81 x 36 = $641.16. Then deduct the total deductions for the week: Total deductions = Federal tax + State tax + Federal insurance + Family health insurance = $102.80 + $24.58 + $18.13 + $52.15 = $197.66. Finally, calculate the nurse's take-home pay: Take-home pay = Total earnings - Total deductions = $641.16 - $197.66 = $443.50. Therefore, the correct answer is A: $443.50, as it accurately reflects the nurse's take-home pay after all deductions. Option B, C, and D are incorrect as they do not reflect the accurate calculations based on the given information.

Correct Answer: A

Rationale: To find the weight of a 7 lb. baby in grams, multiply 7 (lbs) by the conversion factor 453.59 (grams/lb). 7 lbs x 453.59 = 3175.13 grams. Therefore, the correct answer is A. Choice B (4000 grams) is incorrect as it does not consider the precise conversion factor. Choice C (4535 grams) is incorrect as it simply multiplies 7 by 1000. Choice D (3500 grams) is incorrect as it uses a different conversion factor.

Correct Answer: B

Rationale: To find the percentage of band members who missed practice, we need to calculate the ratio of band members who missed practice to the total band members. 9 out of 75 band members missed practice, so the ratio is 9/75 = 0.12 or 12%. Therefore, the correct answer is B (12%). Choice A (10%) is incorrect as 9 out of 75 is not equivalent to 10%. Choice C (15%) is incorrect as 9 out of 75 is not equivalent to 15%. Choice D (18%) is incorrect as 9 out of 75 is not equivalent to 18%.

Correct Answer: C

Rationale: To convert 2 teaspoons to milliliters, we need to know that 1 teaspoon is approximately 4.93 milliliters. Therefore, 2 teaspoons would be 2 * 4.93 = 9.86 milliliters. The correct answer is C (9.86 milliliters). Choice A (4.3 milliliters) is incorrect because it is too low based on the conversion factor. Choice B (9 milliliters) is close but not accurate, as the exact conversion gives 9.86 milliliters. Choice D (4 milliliters) is also incorrect as it is lower than the actual conversion.

Correct Answer: B

Rationale: To find 2/3 of 60, multiply 60 by 2/3, which gives 40. Next, find 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Adding 40 and 15 gives us 55. Therefore, the correct answer is B (55). Choice A (45) is incorrect as it only considers 2/3 of 60 without adding 1/5 of 75. Choices C (15) and D (50) also do not account for both parts of the equation.
