TEAS Practice Math Test

Correct Answer: C

Rationale: To find the number of students who passed the exam, we first need to determine the total number of students who took the exam. Since half of the nursing students took the exam, the number of students who took the exam is 200/2 = 100. Then, three-fifths of those who took the exam passed, which is 3/5 * 100 = 60 students. Therefore, the correct answer is C (60). Choice A (120) is incorrect because it represents the total number of nursing students, not the number of students who passed the exam. Choice B (100) is incorrect because it represents the total number of students who took the exam, not the number who passed. Choice D (50) is incorrect because it does not consider the percentage of students who passed the exam.

Correct Answer: A

Rationale: To calculate Jonathan's monthly bill for x roaming minutes, we need to add the flat rate of $65 to the charge per minute of $0.12 multiplied by the number of roaming minutes x. Therefore, the correct expression is 65 + 0.12x. Choice A (65 + 0.12x) is correct because it accurately represents the total bill by adding the flat rate and the variable charge for roaming minutes. Choices B (65x + 0.12), C (65.12x), and D (65 + 0.12x) are incorrect because they do not correctly combine the flat rate and the charge per minute for roaming. Choice B incorrectly multiplies the flat rate by the variable x, Choice C combines the flat rate and the charge incorrectly, and Choice D does not account for the flat rate in the correct way.

Correct Answer: C

Rationale: To calculate the total square inches of wrapping paper needed, we first find the surface area of the box. The surface area of a rectangular box is calculated by adding the areas of all its faces. For this box, the surface area is 2(14x8) + 2(14x6) + 2(8x6) = 224 + 168 + 96 = 488 square inches. Therefore, the correct answer is C (488). Choice A (56) is incorrect because it is too small and does not account for all sides of the box. Choice B (244) is also incorrect as it is not the total surface area of the box. Choice D (672) is incorrect as it is too large and does not accurately represent the wrapping paper needed.

Correct Answer: C

Rationale: To find the percentage of times Cora did not slip and fall, subtract the times she fell (20) from the total times around the rink (27): 27 - 20 = 7. Then, divide the times she did not fall (7) by the total times (27): 7 / 27 ≈ 0.259 or 26%. The correct answer is C (26%), as it represents the approximate percentage of times Cora did not slip and fall. Explanation for other choices: A: 37% - Incorrect. This percentage does not accurately represent the times Cora did not slip and fall. B: 74% - Incorrect. This percentage is too high and does not align with the calculation. D: 15% - Incorrect. This percentage is too low and does not align with the calculation.

Correct Answer: C

Rationale: The mean time for the women who ran the 200m event at the 2008 Olympic Games can be calculated by summing all the times and dividing by the total number of times. Sum of times = 22.33 + 22.50 + 22.50 + 22.61 + 22.71 + 22.72 + 22.83 + 23.22 = 182.42 Total number of times = 8 Mean time = 182.42 / 8 = 22.8025 ≈ 22.68 sec (Choice C) Therefore, the correct answer is C (22.68 sec) as it is the closest to the calculated mean time. Incorrect choices: A: 22.50 sec - This is not the mean of the given times. B: 22.66 sec - Not the mean. D: 22.77 sec - Not the mean.
