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: D

Rationale: The correct answer is D: 75%. To convert a fraction to a percentage, you multiply the fraction by 100. So, 3/4 x 100 = 75%. This makes choice D the correct answer. Option A (57%) is incorrect because it is not equivalent to 3/4. Option B (7.50%) is also incorrect as it does not represent 3/4. Option C (65%) is incorrect as it is not the equivalent percentage of 3/4.

Correct Answer: C

Rationale: To determine the force needed to stretch the coil by 0.1 meters, we use the formula F = kx, where F is the force, k is the constant of proportionality, and x is the stretch distance. First, calculate k by dividing the given force by the stretch distance: k = 132 N / 0.07 m = 1885.7 N/m. Then, plug in the values: F = 1885.7 N/m * 0.1 m = 188.6 N. Therefore, the correct answer is C (188.6 Newtons). Choice A (92.4 N) is incorrect because it does not consider the direct proportionality between force and stretch. Choice B (1885.7 N) incorrectly assumes the force remains constant regardless of the stretch distance. Choice D (136.0 N) is not rounded to the nearest tenth as requested.

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: 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).
