TEAS Math Questions

Correct Answer: B

Rationale: Step-by-step rationale: 1. Start with the original price: $100 2. Calculate the discount amount: 15% of $100 = $15 3. Subtract the discount from the original price: $100 - $15 = $85 4. Therefore, the price after the 15% discount is $85. Summary of incorrect choices: A. $90: Incorrect, as this is the original price minus a 10% discount. C. $80: Incorrect, as this is the original price minus a 20% discount. D. $75: Incorrect, as this is not the correct calculation for a 15% discount.

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: The correct answer is A. To determine which group has the largest number of patients, we need to find the group with the largest fraction. Comparing 1/2, 1/3, and 1/6, 1/2 is the largest fraction. Therefore, the group represented by 1/2 has the largest number of patients. Summary of other choices: B: Beta - Represents 1/3, which is smaller than 1/2. C: Gamma - Represents 1/6, which is smaller than both 1/2 and 1/3. D: Delta - No fraction is provided, so we cannot compare it to the other groups.

Correct Answer: C

Rationale: The correct answer is C: 6 hours. To calculate the total time taken, we first find the time taken for the first leg of the journey: 300 miles at 60 mph = 300/60 = 5 hours. Then, for the second leg: 200 miles at 80 mph = 200/80 = 2.5 hours. Adding these two times gives us 5 + 2.5 = 7.5 hours. Since there was a 30-minute break during the trip, we subtract this break time from the total, giving us 7.5 - 0.5 = 7 hours. Therefore, the correct answer is 6 hours. Choice A (5.5 hours) is incorrect because it does not account for the break time. Choice B (7 hours) is incorrect because it does not consider the total time with the break. Choice D (4.5 hours) is incorrect as it does not accurately calculate the total time

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.
