TEAS Math Questions

Correct Answer: C

Rationale: The correct order is C: Group Gamma, Group Alpha, Group Beta. Step-by-step rationale: First, calculate the fraction of patients in each group: 1/2 for Alpha, 1/3 for Beta, and 1/6 for Gamma. Next, convert the fractions to a common denominator: 6. This gives 3 patients in Alpha, 2 in Beta, and 1 in Gamma. Therefore, the correct order is Group Gamma (1 patient) < Group Alpha (3 patients) < Group Beta (2 patients). Other choices are incorrect because they do not follow the correct order based on the fraction of patients assigned to each group.

Correct Answer: A

Rationale: To find the total height of the stacked boxes, we simply add the heights of the two boxes together. So, 4 inches (height of the first box) + 6 inches (height of the second box) = 10 inches. Therefore, the correct answer is A: 10 inches. Explanation of other choices: B: 12 inches - Incorrect because adding the heights of 4 inches and 6 inches does not equal 12 inches. C: 8 inches - Incorrect as the total height of the stacked boxes is not 8 inches. D: 9 inches - Incorrect because adding 4 inches and 6 inches does not result in 9 inches.

Correct Answer: C

Rationale: To calculate the total time, first find the time for the first segment: 305 miles / 65 mph = 4.69 hours. Then, add the 15-minute stop: 15 minutes / 60 = 0.25 hours. Next, find the time for the second segment: 162 miles / 80 mph = 2.025 hours. Add up all the times: 4.69 + 0.25 + 2.025 = 6.965 hours. Since this is closest to 6.69 hours (choice C), that is the correct answer. Choices A, B, and D are incorrect because they do not accurately represent the total time elapsed since the trip began.

Correct Answer: C

Rationale: To determine the number of male patients NOT overweight as children, calculate the total number of male patients: 30% of 100 patients = 30 male patients. Then, find the number of overweight male patients: 10% of 30 male patients = 3 overweight males. Subtract the overweight males from the total male patients to get the number of male patients NOT overweight: 30 - 3 = 27. Therefore, the correct answer is C (27). Choice A (3) is incorrect because it represents the number of overweight male patients, not the number of male patients NOT overweight. Choice B (10) is incorrect as it does not consider the calculation of overweight male patients and total male patients. Choice D (30) is incorrect as it represents the total number of male patients, not the number of male patients NOT overweight.

Correct Answer: B

Rationale: To find the percentage of trips that are the longest route, divide the number of longest route trips (3) by the total number of trips (9) and multiply by 100. So, (3/9) * 100 = 33.33% ≈ 33% which corresponds to choice B. Option A (0.25) is incorrect as it represents 25%, not 33%. Option C (0.5) represents 50%, which is incorrect as well. Option D (0.75) represents 75%, which is also incorrect.
