Practice Math TEAS TEST

Correct Answer: D

Rationale: To convert yards to feet, you multiply by 3 since 1 yard = 3 feet. Therefore, 9 yards x 3 feet/yard = 27 feet. Option D is correct. Option A is incorrect as it miscalculates the conversion. Option B and C are also incorrect due to incorrect conversion.

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

Correct Answer: A

Rationale: The correct answer is A: 2W + 2(W + 3). To find the perimeter of a rectangle, you add up all its sides. Given that the length is 3 units greater than the width, the length is represented as W + 3. So, the expression for the perimeter is 2W (for the width) + 2(W + 3) (for the length). This simplifies to 2W + 2W + 6, which further simplifies to 4W + 6, representing the correct perimeter expression. Summary: B: W + W + 3 is incorrect as it only adds the width twice and does not account for the length. C: W(W + 3) is incorrect as it represents the area of the rectangle, not the perimeter. D: 2W + 2(3W) is incorrect as it incorrectly combines the width and length terms in the expression.
