Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: Feet are larger; 1 foot is 0.3048 meters. To determine which is larger, we need to compare the conversion factor. 1 foot is equal to 0.3048 meters, indicating that a foot is smaller than a meter. Therefore, meters are larger than feet. Choice B is incorrect because 1 meter is equivalent to 3.28 feet, showing that a meter is larger. Choice C is incorrect as 1 foot is not 0.5 meters, and Choice D is incorrect as 1 meter is not 2 feet.

Correct Answer: B

Rationale: The correct answer is B: Low positive correlation. This is because the data shows a general increasing trend, but the points are scattered and do not form a tight linear relationship. The correlation coefficient would be closer to 0 than to +1, indicating a weak positive correlation. Choices A and C are incorrect as they suggest stronger correlations, which is not supported by the data. Choice D is incorrect as there is some level of relationship between the variables, even if it is weak.

Correct Answer: A

Rationale: The correct answer is A: 2.54 centimeters in an inch; 0.393 inches in a centimeter. The conversion factor between inches and centimeters is 2.54, derived from the definition of an inch. To convert inches to centimeters, you multiply by 2.54. Conversely, to convert centimeters to inches, you divide by 2.54. The other choices are incorrect because they do not reflect the accurate conversion factor between inches and centimeters. B and C have incorrect conversion ratios, while D has an incorrect relationship between inches and centimeters.

Correct Answer: B

Rationale: The correct answer is B (0.23). To find the percentage donated to support construction, we need to subtract the percentage that went towards construction costs from 100% (total). Therefore, 100% - 23% = 77%. This means that 77% of the funds were donated to support construction. Choice A (0.49), C (0.18), and D (0.1) are incorrect because they do not represent the correct percentage of funds donated to support construction after deducting the construction costs.

Correct Answer: A

Rationale: To solve for x in the equation x + 5 = x - 3, we need to isolate x. Subtract x from both sides to get 5 = -3. This is not possible, so the equation has no solution. Therefore, the correct choice is A: x = -5. This is because when x = -5, -5 + 5 = -5 - 3 simplifies to 0 = -8, which is false. Choices B, C, and D are incorrect because they do not satisfy the original equation when substituted back in.
