TEAS 7 Math Practice Test

Correct Answer: C

Rationale: To determine the amount of blood used for further tests, we first find 1/6 of 500 ml: 1/6 * 500 = 83.33 ml. Therefore, the correct answer is C (83.33 ml), rounded to the nearest hundredth. Choice A (83) is incorrect as it does not account for the decimal value. Choices B (83.3) and D (83.34) are also incorrect as they do not accurately round the calculated value to the nearest hundredth.

Correct Answer: A

Rationale: The correct answer is A: Shifts = (2)(5) + 4. 1. Nurse Cameron worked 5 shifts in week 1. 2. In week 2, she worked twice as many shifts as in week 1, which is 2 * 5 = 10 shifts. 3. In week 3, she added 4 shifts to the number of shifts worked in week 2, which is 10 + 4 = 14 shifts. 4. Therefore, the equation describing the number of shifts Nurse Cameron worked in week 3 is (2)(5) + 4 = 10 + 4 = 14 shifts. Summary of incorrect choices: B: Shifts = (4)(5) + 2 - Incorrect because it does not account for the doubling of shifts in week 2 and the addition of 4 shifts in week 3. C: Shifts = 5 + 2 + 4 - Incorrect as it

Correct Answer: C

Rationale: To determine the number of male patients not overweight as children, we first find the total number of male patients by calculating 30% of 100, which equals 30. Then, we find the number of overweight men (10% of 30), which is 3. Subtracting 3 from the total number of male patients gives us the number of male patients not overweight as children, which is 27 (30 - 3 = 27). Therefore, the correct answer is C. Option A is too low, B does not account for the overweight men, and D is too high based on the calculations.

Correct Answer: A

Rationale: To calculate the percent increase, subtract the initial value from the final value (2219 - 1432 = 787). Then, divide the increase by the initial value and multiply by 100 to get the percentage increase [(787/1432) x 100 ≈ 55%]. Therefore, choice A (55%) is correct. Choice B (36%) is incorrect because it underestimates the actual increase. Choice C (64%) and choice D (42%) are also incorrect as they overestimate the percentage increase.
