Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A: Itself. Any number raised to the power of 1 remains the same number. This is because any number to the power of 1 is equivalent to multiplying that number by 1, which does not change the value of the number. Therefore, when a number is raised to the power of 1, the result is the number itself. Summary of incorrect choices: B: One - Raising any number to the power of 1 does not always result in 1, it results in the original number itself. C: Zero - Raising any non-zero number to the power of 1 does not result in 0. D: The number multiplied by 2 - Raising a number to the power of 1 does not double the number, it remains the same.

Correct Answer: D

Rationale: To find the teacher's total earnings after deductions for 4 weeks, we first calculate the total deductions per week: $72 + $35 + $65 = $172. Then, subtract this total from the teacher's weekly earnings: $730 - $172 = $558. Multiply this by 4 weeks: $558 * 4 = $2,232. Therefore, the correct answer is D. Option A is too low, as it does not account for the deductions. Option B is too high, as it overestimates the earnings. Option C is also incorrect, as it does not consider the deductions accurately.

Correct Answer: A

Rationale: The correct answer is A: A shared multiple of two denominators. In order to add or subtract fractions, they must have a common denominator. This means they need to have the same bottom number. By finding the least common multiple of the denominators, you ensure that the fractions have the same base for accurate calculations. Choice B is incorrect because the common denominator is related to the denominators, not the numerators. Choice C is incorrect as the common denominator specifically refers to the bottom number in fractions. Choice D is incorrect as a common denominator may not necessarily divide evenly into both fractions, but it must be a multiple of both denominators.

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.
