HESI A2 Practice Test Math

Correct Answer: A

Rationale: To change 1/6 to a percent, first divide 1 by 6 to get 0.1667. Then, multiply by 100 to convert it to a percentage, which equals 16.67%. Choice A is correct because it accurately represents the conversion. Choices B, C, and D are incorrect as they do not reflect the accurate calculation for converting 1/6 to a percentage.

Correct Answer: A

Rationale: To calculate the nurse's earnings for the week, we first find her total hours worked: 2(12 hours) + 2(8 hours) = 40 hours. Then, multiply her hourly rate of $22 by the total hours worked: $22/hour x 40 hours = $880. Therefore, the nurse earned $880 for the week. The correct answer is A ($960) because it is the only amount greater than $880, which is the actual amount earned. Choices B, C, and D are incorrect as they are higher or lower than the calculated amount of $880.

Correct Answer: C

Rationale: The correct answer is C (150cm). To calculate the perimeter of the stop sign, you add up the length of all five sides, which is 25cm each. So, 25cm x 5 = 125cm. The rationale behind this is that the perimeter of any polygon is the sum of all its sides. Therefore, the correct perimeter of the stop sign is 125cm. The other choices are incorrect because they do not result from the correct calculation based on the dimensions given. Option A (100cm) is too small, Option B (125cm) is the result of calculating one side only, and Option D (175cm) is too large.
