TEAS Math Questions

Correct Answer: A

Rationale: To find the percentage of staff that is certified and available, we first calculate the percentage of staff on vacation: 35% of the total staff. The remaining staff available to work is 65%. Then, we find 20% of the remaining staff that are certified, which is 20% of 65% = 0.2 * 0.65 = 0.13. Therefore, the correct answer is B: 0.13, as it represents the percentage of staff that is certified and available. Choice A: 0.07 is incorrect because it does not accurately represent the percentage of certified and available staff. Choice C: 0.65 is incorrect as it represents the percentage of staff remaining after vacation, not the percentage that is certified and available. Choice D: 0.8 is incorrect as it does not accurately reflect the calculated percentage of certified and available staff.

Correct Answer: A

Rationale: To find the number of hours spent sleeping, we need to calculate 1/4 of a day. Since a day has 24 hours, 1/4 of 24 is 24/4 = 6 hours. Therefore, the correct answer is A: 6 hours. Choice B (8 hours) is incorrect as it is not 1/4 of a day. Choices C (4 hours) and D (5 hours) are also incorrect as they do not represent 1/4 of a day.

Correct Answer: C

Rationale: To find the number of male patients who were not overweight as children, we first calculate the total number of male patients. Since 70% of the patients were women, 30% were men. This means there were 30 men in the study. Out of these men, 10% were overweight as children, which is 10% of 30, equaling 3 men. Therefore, the remaining men who were not overweight would be 30 - 3 = 27. Therefore, choice C (27) is the correct answer. Choices A, B, and D are incorrect as they do not accurately represent the calculation based on the given information.

Correct Answer: C

Rationale: To find the new perimeter after scaling the rectangle by a factor of 2, we multiply the original dimensions by 2. The original perimeter is 2(5+10) = 30 inches. After scaling, the new width is 5*2 = 10 inches and the new length is 10*2 = 20 inches. The new perimeter is 2(10+20) = 60 inches. Therefore, the correct answer is C. Choice A (30 inches) is incorrect because that is the original perimeter, not the new perimeter after scaling. Choice B (40 inches) is incorrect because it does not consider the correct scaling factor. Choice D (50 inches) is incorrect as it miscalculates the new perimeter after scaling.

Correct Answer: A

Rationale: The correct answer is A: 3 hours. Since the car travels 60 miles in 1 hour, its speed is 60 miles per hour. To travel 180 miles at the same speed, it will take 180 miles / 60 miles per hour = 3 hours. Choice B, C, and D are incorrect because they do not accurately calculate the time required based on the given speed of the car. Choice B is too high, choice C is too low, and choice D is also too high.
