TEAS Test Practice Math

Correct Answer: B

Rationale: To calculate 80% of 30 questions, multiply 30 by 0.80, which equals 24. Joshua needs to answer at least 24 questions correctly to meet the 80% threshold for the scholarship. Therefore, the correct answer is B. Choice A (23) is incorrect because it falls short of 80% of 30 questions. Choices C (26) and D (27) exceed the minimum requirement, making them unnecessary.

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: 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: C

Rationale: Correct Answer: C Rationale: 1. Kyle wants to donate one-fifth of his $950 savings to 8 charities. 2. One-fifth of $950 is $190 ($950 / 5 = $190). 3. If he donates $30 to each charity, $30 x 8 charities = $240. 4. His estimate of donating $240 is more than $190 (one-fifth of $950). 5. Hence, the estimate is not reasonable as $240 exceeds one-fifth of his total savings.
