TEAS Math Practice Test

Correct Answer: A

Rationale: To express 0.0523 as a fraction, we need to consider the decimal places. Since 0.0523 has 4 decimal places, we place the digits after the decimal point over the place value of the last digit, which is 10000. Therefore, the fraction is 523/10000, making choice A the correct answer. Choices B, C, and D are incorrect as they do not reflect the correct placement of decimal digits relative to the decimal point and the corresponding place value.

Correct Answer: D

Rationale: Correct Answer: D (1 apple) Rationale: 1. Xavier starts with 20 apples. 2. He gives half to Emma, leaving him with 10 apples. 3. He gives 6 apples to Jim, leaving him with 4 apples. 4. He uses 3/4 of his remaining 4 apples for the pie, leaving him with 1 apple. Summary: - Choice A (4 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie. - Choice B (6 apples) is incorrect because Xavier gives 6 apples to Jim. - Choice C (2 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie.

Correct Answer: A

Rationale: To find the sum of 3/8 and 5/8, you add the numerators together which gives you 3 + 5 = 8. The denominator remains the same (8). So, the sum is 8/8 which simplifies to 1 whole. Therefore, the correct answer is A: 1. Choice B is incorrect as 1 1/4 is greater than 1. Choice C is incorrect as 01-Feb is not a valid fraction. Choice D is incorrect as 03-Apr is not a valid fraction.

Correct Answer: C

Rationale: The correct answer is C: x = y^2. This equation does not represent a function because it fails the vertical line test, where any vertical line intersects the graph at more than one point. In this case, for each x value, there are two corresponding y values (positive and negative square roots), violating the definition of a function where each input can only have one unique output. Choices A, B, and D all represent functions as each x value corresponds to only one y value, satisfying the function criteria.

Correct Answer: A

Rationale: The mode is the number that appears most frequently in a set. In this case, the number 4 appears twice, which is more frequent than any other number in the set. Therefore, the mode of {4, 4, 5, 7, 8} is 4. Choice B (5), C (7), and D (8) are incorrect because each of these numbers appears only once in the set, making them less frequent than 4. The mode must be the number that appears most often in the set, which is 4.
