TEAS 7 Math Practice Test

Correct Answer: A

Rationale: To find the number of respondents who use smartphones for email, we multiply the percentage (60%) by the total number of respondents (5,000). 60% of 5,000 = 0.60 * 5,000 = 3,000 respondents. Therefore, choice A (3,000 respondents) is the correct answer. Choices B, C, and D are incorrect because they do not reflect the correct calculation based on the given percentage and total number of respondents.

Correct Answer: A

Rationale: To simplify the expression, you first add the numbers together: 1.034 + 0.275 = 1.309. Then, subtract 1.294 from the result: 1.309 - 1.294 = 0.015. Therefore, the correct answer is A (0.015). Choices B, C, and D are incorrect as they do not match the calculated result of 0.015.

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: To calculate the increased dosage, we first find 30% of the current dosage: 270 mg x 0.30 = 81 mg. Then, we add this to the current dosage: 270 mg + 81 mg = 351 mg. Therefore, the correct answer is D. Choice A is incorrect as it is less than the current dosage. Choice B is incorrect as it does not account for the increase. Choice C is incorrect as it does not include the correct percentage increase.

Correct Answer: B

Rationale: The correct answer is B: 23%. To calculate this, we add up the percentages of the other three options (49% + 18% + 10% = 77%) and subtract it from 100% (100% - 77% = 23%). This gives us the percentage of funds donated to support construction costs. The rationale is that the sum of percentages of all options must add up to 100%. Choice A, C, and D are incorrect as they do not add up to 100% when combined, making B the correct answer.
