Practice Math TEAS TEST

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: 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: A

Rationale: Correct Answer: A Rationale: To convert Fahrenheit to Celsius, you first subtract 32 from the Fahrenheit temperature and then divide by 1.8. This is because the conversion formula is (F - 32) / 1.8. To convert Celsius to Fahrenheit, you multiply the Celsius temperature by 1.8 and then add 32. The formula for this conversion is (C * 1.8) + 32. Therefore, choice A is correct as it follows the correct conversion formulas for both Fahrenheit to Celsius and Celsius to Fahrenheit. Summary of other choices: B: Incorrect because dividing by 2 in Fahrenheit to Celsius conversion is incorrect. C: Incorrect because multiplying by 2 in Fahrenheit to Celsius conversion is incorrect. D: Incorrect because subtracting 30 in Fahrenheit to Celsius conversion is incorrect.

Correct Answer: A

Rationale: The correct answer is A because a prime number is defined as a number that is divisible by only 1 and itself. This means prime numbers have exactly two factors, 1 and the number itself, making them indivisible by any other number. Choice B is incorrect because prime numbers are not divisible by any other numbers except 1 and themselves. Choice C is incorrect because prime numbers are not divisible by any number, only by 1 and themselves. Choice D is incorrect because prime numbers actually have exactly two factors, not three.

Correct Answer: A

Rationale: The correct answer is A because to find the least common multiple (LCM) of two numbers, you need to list all the multiples of each number and then identify the smallest common multiple. This method ensures that you consider all possible common multiples and select the smallest one. Explanation for other choices: B: Listing factors and finding the largest common factor would result in the greatest common divisor, not the least common multiple. C: Dividing the largest number by the smallest does not give the LCM; it may give a different value altogether. D: Multiplying the two numbers together gives the product of the numbers, not the LCM.
