Practice Math TEAS TEST

Correct Answer: B

Rationale: To find the sale price of the sweater marked 15% off, you first calculate the discount amount by multiplying $78 by 15% (0.15), which equals $11.70. Then deduct this discount from the original price: $78 - $11.70 = $66. Therefore, choice B ($66) correctly estimates the sale price. Choice A ($12) is too low and does not consider the 15% discount. Choice C ($22) is also too low and does not account for the correct discount amount. Choice D ($69) is close but does not reflect the correct calculation after the 15% discount.

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: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.

Correct Answer: A

Rationale: The correct answer is A because in a proper fraction, the numerator (top number) is less than the denominator (bottom number). This indicates a fraction that is less than 1. In an improper fraction, the numerator is greater than the denominator, representing a fraction that is equal to or greater than 1. Choice B is incorrect because it reverses the definitions of proper and improper fractions. Choice C is incorrect because it suggests that a fraction is proper if the numerator is equal to the denominator, which is incorrect. Choice D is incorrect because it defines an improper fraction as having a numerator equal to the denominator, which is not the case.

Correct Answer: C

Rationale: The independent variable is the variable that is manipulated or changed in an equation. In the equation f(t)=4t+9, 't' is the independent variable because it represents the input value that we can freely choose or vary. We can substitute different values for 't' to see how it affects the output 'f(t)'. On the other hand, 'f' is the dependent variable as it depends on the value of 't'. The constant term '9' and the coefficient '4' are not variables, so they cannot be independent variables. Therefore, choice C (t) is the correct answer. Choices A, B, and D are incorrect because they do not represent the independent variable in the given equation.
