TEAS Test Practice Math

Correct Answer: C

Rationale: To find the total percent deducted, you add the percentages taken for taxes and insurance. 35% + 4% = 39%. Therefore, the correct answer is C (39%). Choice A (20%) is too low, as it only considers the tax deduction. Choice B (31%) and Choice D (42%) are incorrect because they don't account for both deductions.

Correct Answer: A

Rationale: To simplify the given expression, combine like terms with the same variables. The expression 5x - 2y + 4x + y simplifies to 9x - y. Combine the x terms (5x + 4x = 9x) and the y terms (-2y + y = -y) to get 9x - y. This is the simplest form of the expression. The other choices are incorrect because they do not correctly combine the like terms or do not simplify the expression to its simplest form. Option B incorrectly subtracts 3y instead of y. Option C incorrectly adds 3y. Option D is not a simplified form of the expression as it lists x and y separately without combining like terms. So, the correct answer is A: 9x - y.

Correct Answer: B

Rationale: To determine the total liquid in the pot, we add the volume of chicken broth (4 containers x 410ml) to the volume of water (1 liter = 1000ml). Total liquid = (4 x 410) + 1000 = 1640 + 1000 = 2640ml = 2.64 liters. Therefore, the correct answer is B. Choice A is incorrect as it miscalculates the total liquid. Choice C and D are significantly higher than the correct answer, indicating an error in calculation.

Correct Answer: C

Rationale: To find the dimensions of the dilated triangle, we multiply each side length by the scale factor x. Given the original triangle has sides 9 cm, 4 cm, and 7 cm, the scale factor x is the ratio of the corresponding sides of the original and dilated triangles. Calculating the ratios for each side: 9/x = 6.75, 4/x = 3, 7/x = 5.25. Solving for x, we get x = 1.33. Multiplying each side by the scale factor gives the dimensions of the dilated triangle as 6.75 cm, 3 cm, and 5.25 cm, which matches option C. Option A, B, and D have incorrect dimensions as they do not match the correct calculations.

Correct Answer: B

Rationale: To find the square root of 1296, we look for a number that, when multiplied by itself, equals 1296. The square root of 1296 is 36 because 36 * 36 = 1296. Choice A (24) is incorrect since 24 * 24 is not equal to 1296. Choice C (31) and Choice D (12) are also incorrect as neither of them results in the square of 1296 when multiplied by themselves. Therefore, the correct answer is B (36).
