Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.

Correct Answer: D

Rationale: To calculate a 10% tip on a $28.40 bill, you multiply $28.40 by 0.10, which equals $2.84. Rounding up to the nearest dollar gives an estimated gratuity of $3.00. Choice D is correct because it accurately represents a 10% tip on the bill. Choices A, B, and C are incorrect as they do not reflect the correct calculation for a 10% tip on the given bill amount.

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: Eritrea. To determine the largest increase in healthcare spending per capita from 2013 to 2015, we need to calculate the difference between the spending in 2015 and 2013 for each country. By comparing the dollar amount increase for each country, it is evident that Eritrea experienced the largest increase. This is because the dollar amount increase for Eritrea is greater than that of the other countries listed. Sudan, Tanzania, and Kenya had smaller increases in dollars spent per capita during the same period. Therefore, A is the correct answer.

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).
