TEAS Math Practice Test

Correct Answer: D

Rationale: To find the sum of 3/4 and 5/8, we need a common denominator, which is 8. 3/4 is equivalent to 6/8, so the sum becomes 6/8 + 5/8 = 11/8. 11/8 can be simplified to 1 3/8, which is answer choice A. Therefore, the correct answer is D, 1 5/8. Choices A, B, and C are incorrect as they do not represent the correct sum of the fractions.

Correct Answer: A

Rationale: The correct answer is A: 75 dollars per gigabyte. The slope of the equation represents the rate of change in cost per unit change in data usage. In this case, for every additional gigabyte of data used (D), the cost of the phone bill (C) increases by $75. This interpretation aligns with the equation C = 50 + 75D, where 75 is the coefficient of D, indicating the cost per gigabyte. Summary of other choices: B: 75 gigabytes per day - This is incorrect as it does not reflect the cost per gigabyte relationship in the equation. C: 50 dollars per day - This is incorrect as it does not account for the cost associated with data usage. D: 50 dollars per gigabyte - This is incorrect because the correct cost per gigabyte is $75, not $50.

Correct Answer: A

Rationale: To round 8.067 to the nearest tenth, we look at the hundredth place, which is 6. Since 6 is equal to or greater than 5, we round the digit in the tenths place up by 1. Therefore, 8.067 rounded to the nearest tenth is 8.1. Choice A is correct because it correctly follows the rounding rule. Choice B is incorrect as it is a duplicate of Choice A. Choice C is incorrect as it rounds down to the nearest whole number, not the nearest tenth. Choice D is incorrect as it rounds up to the hundredth place, not the nearest tenth.
