TEAS Practice Math Test

Correct Answer: C

Rationale: To find the percentage of times Cora did not slip and fall, subtract the times she fell (20) from the total times around the rink (27): 27 - 20 = 7. Then, divide the times she did not fall (7) by the total times (27): 7 / 27 ≈ 0.259 or 26%. The correct answer is C (26%), as it represents the approximate percentage of times Cora did not slip and fall. Explanation for other choices: A: 37% - Incorrect. This percentage does not accurately represent the times Cora did not slip and fall. B: 74% - Incorrect. This percentage is too high and does not align with the calculation. D: 15% - Incorrect. This percentage is too low and does not align with the calculation.

Correct Answer: B

Rationale: The best estimate of the total number of pounds of potatoes on the farmer's trailer can be calculated by finding the average weight per bag and then multiplying it by the total number of bags. Since each bag contains between 23 to 27 pounds, we can estimate the average weight per bag to be around 25 pounds. With 150 bags, the total weight would be approximately 150 bags * 25 pounds per bag = 3,750 pounds. Therefore, the best estimate is 3,700 pounds (Choice B). Choice A (3,000 pounds) is too low as it assumes the lowest possible weight per bag consistently. Choice C (4,100 pounds) is too high as it assumes the highest possible weight per bag consistently. Choice D (5,000 pounds) is also too high and overestimates the total weight based on the given information.

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.

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: A

Rationale: The correct answer is A (35). To find the number of students who chose blue, multiply the total number of students by the percentage that chose blue: 100 x 0.35 = 35. This calculation gives us the number of students who said blue is their favorite color. The other choices are incorrect because they do not correctly calculate the number of students who chose blue based on the given percentage. Choice B (25), C (20), and D (10) do not accurately represent 35% of the total number of students. Therefore, choice A is the correct answer based on the calculation method provided.
