TEAS Test Math Questions

Correct Answer: A

Rationale: The perimeter of a square is calculated by adding up all four sides. Since all sides of a square are equal, the perimeter is 4 times the length of one side. In this case, the side length is 6 cm, so the perimeter would be 4*6 = 24 cm. Therefore, choice A (24 cm) is correct. Choices B, C, and D are incorrect because they do not correctly calculate the perimeter of a square with a side length of 6 cm. Choice B (12 cm) is half the correct answer, choice C (18 cm) is three-quarters of the correct answer, and choice D (36 cm) is double the correct answer.

Correct Answer: A

Rationale: To find how many feet of wood remain, subtract the length cut off from the original length. 7 1/2 - 3 1/4 = 4 1/4. Therefore, the correct answer is A: 4 1/4 feet. Choice B, 4 1/2 feet, is incorrect as it does not match the subtraction result. Choice C, 3 1/2 feet, is incorrect as it does not account for the fraction left after subtracting. Choice D, 3 3/4 feet, is incorrect as it overestimates the amount left after the cut.

Correct Answer: D

Rationale: To determine the correct answer, we need to find the value of x in each proportion. For choice A, x = 4; for choice B, x = 8; for choice C, x = 6; and for choice D, x = 10. So, the correct answer is D because it yields a different value for x compared to the other choices. Choices A, B, and C all have x values that are multiples of 2, whereas choice D has a different x value. Therefore, choice D is the only proportion that yields a different number for the unknown compared to the others.

Correct Answer: C

Rationale: The correct answer is C: Zero. When two numbers are equal, their difference is always zero. This is because the distance between two equal numbers on the number line is zero. Any other choice is incorrect because a negative or positive difference implies inequality, which contradicts the premise that the numbers are equal. Choice D is also incorrect as there is sufficient information to determine the difference between two equal numbers.

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.
