TEAS Test Math Questions

Correct Answer: D

Rationale: To convert a percentage to a fraction, we divide the percentage by 100. So, 290% is equal to 290/100. Simplifying this fraction gives us 29/10. Therefore, the correct answer is D. Option A (29/10) is the simplified form of the correct answer. Option B (58/20) and Option C (145/50) are incorrect as they are not equivalent to 290%.

Correct Answer: D

Rationale: To find the rate of change in height per month, we multiply the daily growth rate by the number of days in a month. 4.2 inches/day * 30 days = 126 inches/month. Therefore, the correct answer is D. Choice A is incorrect as it is the daily growth rate, not the monthly rate. Choice B is incorrect as it is the same as the daily growth rate, not the monthly rate. Choice C is incorrect as it is not the result of the correct calculation.

Correct Answer: A

Rationale: To simplify (x^2 - y^2) / (x - y), we recognize it as a difference of squares, (x^2 - y^2) = (x + y)(x - y). Therefore, the expression simplifies to (x + y). The correct answer is A because when we divide (x + y)(x - y) by (x - y), the (x - y) terms cancel out, leaving us with x + y. Choices B, C, and D are incorrect because they do not consider the factorization of the numerator as a difference of squares, leading to incorrect simplifications.

Correct Answer: A

Rationale: To calculate how many times larger the first cell is compared to the second, we divide the diameter of the first cell by the diameter of the second cell: 0.1 / 0.05 = 2. Therefore, the correct answer is A: 2. Option B, C, and D are incorrect because they do not accurately represent the ratio between the two cell sizes based on the given diameters.

Correct Answer: A

Rationale: To solve |x| = 10, we consider both possibilities: x = 10 and x = -10 since the absolute value of x is always positive. So, the correct answer is A: -10, 10. Choice B, C, and D are incorrect because they do not reflect the correct solutions to the absolute value equation given.
