TEAS Practice Test Math

Correct Answer: C

Rationale: To convert milliliters to liters, divide by 1000 since there are 1000 mL in 1 L. Here, 2500 mL ÷ 1000 = 2.5 L. Therefore, the correct answer is C (2.5 L). Choice A (0.25 L) is incorrect because the decimal point is in the wrong place. Choice B (25 L) and D (250 L) are incorrect as they are significantly higher than the actual conversion.

Correct Answer: C

Rationale: The correct answer is C: 1.2 hours. To find the combined time it takes for both A and B to mow the lawn together, we use the formula: 1/(1/A + 1/B). Substituting A=2 and B=3 into the formula, we get 1/(1/2 + 1/3) = 1/(5/6) = 6/5 = 1.2 hours. This is the time it would take for both A and B to mow the lawn together. Summary of other choices: A: 5 hours - Incorrect. This answer is obtained by simply adding the individual times of A and B, which is not the correct method for combining their work rates. B: 2.5 hours - Incorrect. This choice is halfway between the individual times of A and B, which is not the correct way to calculate the combined time. D: 1 hour - Incorrect. This choice is

Correct Answer: A

Rationale: The correct answer is A because an exponent is a number that indicates how many times a base number is multiplied by itself. For example, in 2^3, 3 is the exponent telling us to multiply 2 by itself 3 times. Choice B is incorrect because an exponent is not the number being multiplied, but the number indicating how many times to multiply. Choice C is incorrect as an exponent does not involve division. Choice D is incorrect as it refers specifically to squaring a number, whereas exponents can apply to any power beyond just squaring.

Correct Answer: A

Rationale: The correct answer is A because the greatest common factor is the largest factor that divides all the given numbers without a remainder. This factor is common to all numbers and is the greatest among all the common factors. Choice B is incorrect because the smallest factor does not account for all numbers. Choice C is incorrect as the greatest common factor is not a multiple, but a factor. Choice D is incorrect since the smallest multiple does not necessarily divide all the numbers without a remainder.

Correct Answer: C

Rationale: To find the amount the friend paid for their car, we need to set up an equation. Let x be the friend's car price. The consumer paid $48,000, which is $2,000 less than twice the friend's car price, so 2x - $2,000 = $48,000. Solving for x, 2x = $48,000 + $2,000 = $50,000, therefore x = $25,000. Choice C is correct. Choices A, B, and D do not satisfy the given condition in the question. A is less than $25,000, B is greater than $25,000 but not $2,000 less than twice, and D is greater than $25,000.
