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: The correct answer is B: Stocks. In this scenario, stocks are the independent variable because they are being manipulated or controlled to observe the effect on other variables like production, sales, and investments. Increasing stocks is the action taken, which then leads to the changes in production, sales, and investments. On the other hand, choices A, C, and D are dependent variables as they are influenced by the changes in stocks. Sales, production, and investments are all outcomes or results of the changes in stocks. Therefore, stocks are the independent variable in this situation.

Correct Answer: C

Rationale: The correct answer is C (12.325 mL). To calculate this, first, convert 2.5 teaspoons to mL by multiplying by 4.93: 2.5 * 4.93 = 12.325 mL. Choice A (5.33 mL) is incorrect because it is less than the correct amount. Choice B (7.43 mL) is also incorrect as it is lower than the correct value. Choice D (0.507 mL) is incorrect because it is significantly lower than the correct amount. Therefore, the correct answer is C as it accurately reflects the conversion of teaspoons to milliliters based on the given conversion rate.

Correct Answer: A

Rationale: The correct answer is A: 1000 mL. This is because there are 1000 milliliters in a liter based on the metric system conversion. 1 liter is equal to 1000 milliliters. Therefore, to convert liters to milliliters, you simply multiply the number of liters by 1000. Choice B: 100 mL is incorrect because it is not the standard conversion factor for liters to milliliters. Choice C: 10 mL is incorrect as it is too small of a quantity to be equivalent to a liter. Choice D: 1 mL is incorrect as it is significantly less than a liter.

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.
