TEAS Exam Math Practice

Correct Answer: B

Rationale: To convert 8 pounds and 8 ounces to kilograms, first convert pounds to kilograms (1 lb = 0.453592 kg) and ounces to kilograms (1 oz = 0.0283495 kg). So, 8 lbs + 8 oz is approximately 3.9 kg. Therefore, choice B (3.9 kilograms) is the correct equivalent. Choice A (3.6 kg) is too low, and choices C (17.6 kg) and D (18.7 kg) are too high based on the conversion rates.

Correct Answer: C

Rationale: To find the perimeter of the square, we first need to find the side length. Since the area of a square is side length squared (5625 = side length x side length), the side length is √5625 = 75 feet. The perimeter of a square is 4 times the side length, so 4 x 75 = 300 feet. Therefore, Melissa needs 300 feet of fencing. Summary: A) 75 feet - Incorrect. This is the side length, not the perimeter. B) 150 feet - Incorrect. This is half the perimeter. C) 300 feet - Correct. The perimeter of the square. D) 5,625 feet - Incorrect. This is the total area, not the perimeter.

Correct Answer: B

Correct Answer: B

Rationale: To find the total area to be painted, calculate the area of each wall in square feet and convert to square meters. Add all areas together. Then divide by 32 to get the number of gallons. For this case, the correct answer is B: 1.43 gallons. This is calculated by first finding the total area to be painted which is 15x9 + 15x9 + 12.5x9 + 12.5x9 = 337.5 square feet. Converting this to square meters gives 31.36 square meters. Dividing by 32 (the coverage per gallon) gives approximately 1.43 gallons. The other choices are incorrect because they do not reflect the accurate calculation based on the given information.

Correct Answer: D

Rationale: To determine the order from least to greatest, we need to evaluate each expression. First, calculate each expression: 2^-1 = 1/2 -(4/3) = -4/3 (-1)^3 = -1 (2/5) = 2/5 Now, compare the values: -4/3 is the smallest, followed by -1, then 2/5, and finally 1/2. Therefore, the correct order is -(4/3), (-1)^3, (2/5), 2^-1. Option D correctly lists the expressions in this order. Option A is incorrect because it has the wrong order of the expressions. Option B is incorrect as it has a different order compared to the correct one. Option C is incorrect as it also has a different order than the correct one.
