TEAS Test Math Questions

Correct Answer: A

Rationale: The perimeter of a square is calculated by adding up all four sides. Since all sides of a square are equal, the perimeter is 4 times the length of one side. In this case, the side length is 6 cm, so the perimeter would be 4*6 = 24 cm. Therefore, choice A (24 cm) is correct. Choices B, C, and D are incorrect because they do not correctly calculate the perimeter of a square with a side length of 6 cm. Choice B (12 cm) is half the correct answer, choice C (18 cm) is three-quarters of the correct answer, and choice D (36 cm) is double the correct answer.

Correct Answer: A

Rationale: To multiply fractions, you simply multiply the numerators and denominators separately. So, (3/5) * (5/8) = (3*5)/(5*8) = 15/40. However, it can be simplified to 3/8 by dividing both numerator and denominator by 5. Thus, the correct answer is A: 3/8. Choice B (3/5) is the first fraction, not the result. Choice C (15/40) is the intermediate result before simplification. Choice D (3/30) is incorrect as the numerator should be 15, not 3.

Correct Answer: D

Rationale: To simplify the expression 3x - 5x + 2, we first combine like terms. 3x - 5x = -2x, so the expression becomes -2x + 2. Thus, the correct answer is D: -2x. Choice A is incorrect as it incorrectly combines the x terms without changing their signs. Choice B is incorrect as it only considers the x terms and ignores the constant term. Choice C is incorrect as it incorrectly combines the x terms without changing their signs.

Correct Answer: D

Rationale: To find the area of a circle, we use the formula A = πr^2, where r is the radius. Since the diameter is 16 cm, the radius is half of that, which is 8 cm. Plugging this into the formula, A = 3.14 * 8^2 = 3.14 * 64 = 200.96 cm^2. Therefore, the correct answer is D. Choice A: 25.12 - This is incorrect as it is much smaller than the correct answer. Choice B: 50.24 - This is incorrect as it is also smaller than the correct answer. Choice C: 100.48 - This is incorrect as it is still smaller than the correct answer.

Correct Answer: B

Rationale: To find the area that needs weeding, we first calculate the area of the entire circle using the formula A = πr^2. Substituting the radius (11.5 feet) into the formula gives A = 3.14 * 11.5^2 ≈ 415.49 sq ft. Since only half needs weeding, we divide this by 2 to get 207.74 sq ft, which rounds to 207.64 sq ft (Option B). Other choices are incorrect because they either don't consider halving the area or use incorrect calculations.
