TEAS Practice Math Test

Correct Answer: C

Rationale: To find the number of hairs used for the drug test, we need to calculate 1/7 of 100 hairs. 1/7 * 100 = 100/7 ≈ 14.29 hairs were used for the drug test. Therefore, the correct answer is C (14.29). Option A (14) is incorrect as it does not accurately represent 1/7 of 100. Option B (14.2) is also incorrect as it is not the exact result of the calculation. Option D (14.3) is incorrect as it rounds up the result, which is not necessary based on the question's requirement to round to the nearest hundredth.

Correct Answer: C

Rationale: To convert meters to centimeters, we know that 1 meter is equal to 100 centimeters. So, to find how many centimeters are in 7 meters, we multiply 7 by 100, which equals 700 centimeters. Therefore, the correct answer is C. Choice A is incorrect because it doesn't account for the conversion factor between meters and centimeters. Choice B is incorrect as it only considers 1 meter as 10 centimeters instead of 100. Choice D is incorrect as it overestimates the conversion, as 7 meters is not equal to 7000 centimeters.

Correct Answer: C

Rationale: To find the percentage of times Cora did not slip and fall, subtract the times she fell (20) from the total times around the rink (27): 27 - 20 = 7. Then, divide the times she did not fall (7) by the total times (27): 7 / 27 ≈ 0.259 or 26%. The correct answer is C (26%), as it represents the approximate percentage of times Cora did not slip and fall. Explanation for other choices: A: 37% - Incorrect. This percentage does not accurately represent the times Cora did not slip and fall. B: 74% - Incorrect. This percentage is too high and does not align with the calculation. D: 15% - Incorrect. This percentage is too low and does not align with the calculation.

Correct Answer: A

Rationale: The correct answer is A: x + 4 = (1/3)y - 2. To break down the equation: 1. "Four more than a number, x" can be represented as x + 4. 2. "2 less than 1/3 of another number, y" can be represented as (1/3)y - 2. 3. Combining the two expressions gives x + 4 = (1/3)y - 2, which correctly represents the given sentence. Other choices are incorrect because they do not accurately capture the relationship between x and y as described in the sentence. Choice B incorrectly sets 4x equal to 2 minus 1/3 of y, while choices C and D have incorrect signs and placements of terms.
