TEAS Practice Math Test

Correct Answer: D

Rationale: To convert grams to milligrams, you need to multiply by 1000 because 1 gram = 1000 milligrams. Therefore, to find how many milligrams are in 5 grams, you would multiply 5 grams by 1000, resulting in 5000 milligrams. Option D is correct. Option A is incorrect as it represents a conversion from grams to micrograms, not milligrams. Option B is incorrect as it is a tenth of the correct answer. Option C is incorrect as it is only a hundredth of the correct answer.

Correct Answer: A

Rationale: The correct answer is A: 3600 cubic inches. To calculate the volume of the aquarium, you multiply the length, width, and height: 30 x 10 x 12 = 3600 cubic inches. This is the total capacity of the aquarium when filled completely. Choice B (52 cubic inches) is too small as it doesn't consider the full dimensions of the aquarium. Choice C (312 cubic inches) and Choice D (1144 cubic inches) are incorrect because they do not accurately calculate the volume based on the given dimensions.

Correct Answer: B

Rationale: The correct answer is B: b = 5w + 10. To determine the correct equation, we can analyze the data in the table given. We can observe that when the number of weeks increases by 1, the number of books checked out increases by 5. This indicates a constant rate of increase of 5 books per week, which aligns with the equation b = 5w + 10. The initial value of 10 represents the number of books already checked out before week 1. Choices A, C, and D do not exhibit a constant rate of increase or the correct initial value based on the data provided.

Correct Answer: B

Rationale: To simplify 0.0178 * 2.401, multiply the numbers to get 0.0427378. This is the correct answer (B). The other choices are incorrect because they do not result from the correct multiplication of the given numbers. Option A, 2.0358414, is the sum of the two numbers rather than the product. Option C, 0.2341695, and option D, 0.348324, are not the correct results of multiplying 0.0178 and 2.401.

Correct Answer: C

Rationale: To calculate the total square inches of wrapping paper needed, we first find the surface area of the box. The surface area of a rectangular box is calculated by adding the areas of all its faces. For this box, the surface area is 2(14x8) + 2(14x6) + 2(8x6) = 224 + 168 + 96 = 488 square inches. Therefore, the correct answer is C (488). Choice A (56) is incorrect because it is too small and does not account for all sides of the box. Choice B (244) is also incorrect as it is not the total surface area of the box. Choice D (672) is incorrect as it is too large and does not accurately represent the wrapping paper needed.
