TEAS Practice Test Math

Correct Answer: A

Rationale: The correct answer is A: One. When the number 1 is raised to any power, the result is always 1. This is because any number raised to the power of 1 is equal to that number itself. In this case, 1 raised to any power will always be 1. Summary: Choice B (Itself) is incorrect because raising 1 to any power does not result in the number itself, but always in 1. Choice C (Zero) is incorrect as any number raised to the power of 0 is 1, not 0. Choice D (Two) is incorrect as it is not possible for 1 raised to any power to equal 2.

Correct Answer: A

Rationale: To simplify 3.45 * 0.53, multiply the numbers together: 3.45 * 0.53 = 1.8285 (Answer A). This is correct because when multiplying decimals, you multiply as if they were whole numbers and then place the decimal point in the answer based on the total number of decimal places in the factors. Summary of other choices: B: 18.285 - Incorrect as it is the result of adding the two numbers. C: 0.18285 - Incorrect as it is the result of placing the decimal point incorrectly. D: 182.85 - Incorrect as it is the result of ignoring the decimal places in the factors.

Correct Answer: D

Rationale: To calculate the increased dosage, we first find 30% of 270 mg by multiplying 270 by 0.30, which equals 81 mg. Then, we add the increase to the current dosage: 270 mg + 81 mg = 351 mg. Therefore, the correct answer is D. Choice A (81 mg) is incorrect because that is only the increase, not the total dosage. Choice B (270 mg) is the current dosage, not the increased dosage. Choice C (300 mg) is also incorrect as it does not account for the 30% increase.

Correct Answer: A

Rationale: To determine the amount of yogurt, we first find the total parts in the ratio (4+3=7 parts). Since toppings are 3 parts, we divide 4.5 oz by 3 to find 1 part equals 1.5 oz. Then, multiply 1.5 oz by 4 (yogurt parts) to get 6 oz of yogurt. Choice A is correct because it correctly calculates the amount of yogurt based on the given ratio. Choices B, C, and D are incorrect as they do not follow the correct calculation based on the ratio provided.
