Practice Math TEAS TEST

Correct Answer: C

Rationale: To convert 45 kg to pounds, multiply by the conversion factor 2.2 lbs/kg. So, 45 kg * 2.2 lbs/kg = 99 lbs. Therefore, the correct answer is C. Choice A (120 lbs) is incorrect as it is not the result of the conversion calculation. Choice B (89 lbs) is also incorrect as it does not match the conversion result. Choice D (90 lbs) is incorrect because the correct equivalent weight is 99 lbs, not 90 lbs.

Correct Answer: B

Rationale: To solve the equation 3(2x+5)=11x+5 for x, first distribute the 3 on the left side to get 6x+15=11x+5. Next, move all terms with x to one side by subtracting 6x from both sides to get 15=5x+5. Then, subtract 5 from both sides to get 10=5x. Finally, divide by 5 to solve for x, giving x=2. Therefore, the correct answer is B. Choice A is incorrect because x is not equal to 1. Choice C is incorrect because x is not equal to -1. Choice D is incorrect because x is not equal to -2.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Given equation: D = 2R 2. To find the relationship between D and R, we see that D is equal to 2 times R. 3. Thus, D is twice as much as R, making choice A the correct answer. 4. Other choices are incorrect: - B: R is twice as much as D (incorrect as the equation shows D is twice R). - C: R is two times D (incorrect as the equation states D is two times R). - D: D is two more than R (incorrect as D is actually two times R).

Correct Answer: C

Rationale: The independent variable is the variable that is manipulated or changed in an equation. In the equation f(t)=4t+9, 't' is the independent variable because it represents the input value that we can freely choose or vary. We can substitute different values for 't' to see how it affects the output 'f(t)'. On the other hand, 'f' is the dependent variable as it depends on the value of 't'. The constant term '9' and the coefficient '4' are not variables, so they cannot be independent variables. Therefore, choice C (t) is the correct answer. Choices A, B, and D are incorrect because they do not represent the independent variable in the given equation.

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.
