TEAS Test Math Questions

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.

Correct Answer: C

Rationale: To determine the smallest decimal, compare the digits from left to right. In choice C (2.002), the first non-zero digit is in the thousandths place, making it smaller than choices A, B, and D. Choice A (2.22) has the first non-zero digit in the tenths place, making it larger than choice C. Choice B (2.02) has a smaller tenths place digit than choice A but a larger hundredths place digit, still making it larger than choice C. Choice D (2.2) has the first non-zero digit in the tenths place, which is larger than choice C. Therefore, the correct answer is C (2.002) as it has the smallest value among the given options.

Correct Answer: D

Rationale: The correct answer is D: (7, 8). To find the fourth vertex of the parallelogram, we can use the property that opposite sides of a parallelogram are parallel and equal in length. By calculating the vector between the points (1, 2) and (3, 4) as (2, 2), we can extend this vector from the point (5, 6) to find the fourth vertex at (5 + 2, 6 + 2) = (7, 8). Option A is incorrect as it does not satisfy the parallelogram property. Option B does not maintain the same distance between points. Option C does not form a parallelogram with the given points.

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: B

Rationale: To find the difference between two negative numbers, we subtract the second negative number from the first. When we subtract a negative number from another negative number, it is equivalent to adding the positive value of the second number to the first number. This results in a positive number as the answer, making choice B (Positive number) the correct answer. Choices A, C, and D are incorrect because the result of subtracting two negative numbers is always a positive number, not another negative number, zero, or not enough information.
