Practice Math TEAS TEST

Correct Answer: A

Rationale: To find the length of the unknown leg, we can use the Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of a right triangle. Given a = 9 feet and c = 19 feet, we can solve for b: 9^2 + b^2 = 19^2 81 + b^2 = 361 b^2 = 280 b ≈ √280 ≈ 16.7 feet Therefore, the correct answer is A (16.7 feet). Choice B (16.0 feet) is incorrect as it does not account for rounding to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value.

Correct Answer: C

Rationale: The correct answer is C (12.325 mL). To calculate this, first, convert 2.5 teaspoons to mL by multiplying by 4.93: 2.5 * 4.93 = 12.325 mL. Choice A (5.33 mL) is incorrect because it is less than the correct amount. Choice B (7.43 mL) is also incorrect as it is lower than the correct value. Choice D (0.507 mL) is incorrect because it is significantly lower than the correct amount. Therefore, the correct answer is C as it accurately reflects the conversion of teaspoons to milliliters based on the given conversion rate.

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.
