Practice Math TEAS TEST

Correct Answer: D

Rationale: To find the answer, calculate the volume of the room: 9 ft * 9 ft * 9 ft = 729 cubic feet. Then, calculate the volume of one box: 2 ft * 2 ft * 2 ft = 8 cubic feet. Divide the room's volume by the box's volume: 729 cubic feet / 8 cubic feet = 91.125. Since we can't have a fraction of a box, the maximum number of whole boxes that can be stored is 91, which is closest to option D: 92. Option A (125) is too high, option B (64) is too low, and option C (18) is also too low.

Correct Answer: A

Rationale: The correct answer is A: A shared multiple of two denominators. In order to add or subtract fractions, they must have a common denominator. This means they need to have the same bottom number. By finding the least common multiple of the denominators, you ensure that the fractions have the same base for accurate calculations. Choice B is incorrect because the common denominator is related to the denominators, not the numerators. Choice C is incorrect as the common denominator specifically refers to the bottom number in fractions. Choice D is incorrect as a common denominator may not necessarily divide evenly into both fractions, but it must be a multiple of both denominators.

Correct Answer: C

Rationale: The data set has two distinct peaks at values 2 and 8, making it bimodal. This is evident as there are two modes in the data set. The frequencies of 2 and 8 are higher compared to the other values, creating the bimodal distribution. Choices A, B, and D are incorrect. A uniform distribution would have equal frequencies for all values, which is not the case here. Right-skewed distribution would have a long tail on the right side, which is also not observed. Left-skewed distribution would have a long tail on the left side, which is not the case here.

Correct Answer: D

Rationale: To find the teacher's total earnings after deductions for 4 weeks, we first calculate the total deductions per week: $72 + $35 + $65 = $172. Then, subtract this total from the teacher's weekly earnings: $730 - $172 = $558. Multiply this by 4 weeks: $558 * 4 = $2,232. Therefore, the correct answer is D. Option A is too low, as it does not account for the deductions. Option B is too high, as it overestimates the earnings. Option C is also incorrect, as it does not consider the deductions accurately.
