HESI A2 Practice Test Math

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: A

Rationale: The correct answer is A: 579 copies. To find the number of copies each person made, divide the total number of copies (3,475) by the number of people who used the copier (6). 3,475 ÷ 6 = 579. Each person made 579 copies. Summary: - Choice B (680 copies) is incorrect because it does not evenly divide into the total number of copies. - Choice C (670 copies) is incorrect because it is not an even division of the total number of copies. - Choice D (585 copies) is incorrect because it is not the result of dividing the total number of copies by the number of people who used the copier.

Correct Answer: A

Rationale: To solve 4/5 + 6/7, find a common denominator: 35. 4/5 = 28/35 and 6/7 = 30/35. Adding these gives 28/35 + 30/35 = 58/35 = 1 23/35. Therefore, the correct answer is A (1 23/35). The other choices are incorrect as they do not correctly calculate the sum of the fractions. B (2 5/7), C (1 1/7), and D (1 3/4) are not the result of the given expression.

Correct Answer: C

Rationale: To calculate 0.9 divided by 3, we divide 0.9 by 3, which equals 0.3. This is the correct answer (C) because dividing 0.9 by 3 results in 0.3. Option A (0) is incorrect as the division does not equal 0. Option B (3) is incorrect as the result is not equal to 3. Option D (9) is incorrect as the division does not equal 9. Therefore, the correct answer is C (0.3).
