Practice Math TEAS TEST

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.

Correct Answer: B

Rationale: To calculate the percentage increase, subtract the initial value from the final value, then divide by the initial value and multiply by 100. Percentage Increase = [(1072-841)/841] x 100 ≈ 27% Therefore, choice B (27%) is the correct answer as it represents the approximate percentage increase in client volume. Choice A (22%) is incorrect because it does not accurately reflect the calculated percentage increase. Choice C (127%) is incorrect as it is way too high and does not align with the actual increase. Choice D (78%) is incorrect as it is also significantly off from the calculated percentage increase.

Correct Answer: B

Rationale: The correct answer is B: Stocks. In this scenario, stocks are the independent variable because they are being manipulated or controlled to observe the effect on other variables like production, sales, and investments. Increasing stocks is the action taken, which then leads to the changes in production, sales, and investments. On the other hand, choices A, C, and D are dependent variables as they are influenced by the changes in stocks. Sales, production, and investments are all outcomes or results of the changes in stocks. Therefore, stocks are the independent variable in this situation.

Correct Answer: D

Rationale: To find the portion each of the other three friends received, we first calculate what fraction of the pizza was left after one friend ate half. Half of the pizza is 1/2, so 1 - 1/2 = 1/2 is left. Then, we divide 1/2 equally among the three friends, giving each 1/2 ÷ 3 = 1/6. Therefore, each of the other three friends received 1/6 of the pizza. Summary: A: 1/5 - Incorrect. Not the correct division after one friend ate half. B: 1/3 - Incorrect. The correct division is not one-third after one friend ate half. C: 1/4 - Incorrect. The correct division is not one-fourth after one friend ate half.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.
