TEAS Math Questions

Correct Answer: B

Rationale: Step-by-step rationale: 1. Start with the original price: $100 2. Calculate the discount amount: 15% of $100 = $15 3. Subtract the discount from the original price: $100 - $15 = $85 4. Therefore, the price after the 15% discount is $85. Summary of incorrect choices: A. $90: Incorrect, as this is the original price minus a 10% discount. C. $80: Incorrect, as this is the original price minus a 20% discount. D. $75: Incorrect, as this is not the correct calculation for a 15% discount.

Correct Answer: A

Rationale: To find the perimeter of a rectangle, you add all four sides. Given the width is 4 inches, and the length is 3 times the width (12 inches), the perimeter would be 2(4 + 12) = 2(16) = 32 inches. Therefore, the correct answer is A (28 inches). The other choices are incorrect because they do not match the calculated perimeter based on the given dimensions of the rectangle.

Correct Answer: C

Rationale: The correct order is C: Group Gamma, Group Alpha, Group Beta. Step-by-step rationale: First, calculate the fraction of patients in each group: 1/2 for Alpha, 1/3 for Beta, and 1/6 for Gamma. Next, convert the fractions to a common denominator: 6. This gives 3 patients in Alpha, 2 in Beta, and 1 in Gamma. Therefore, the correct order is Group Gamma (1 patient) < Group Alpha (3 patients) < Group Beta (2 patients). Other choices are incorrect because they do not follow the correct order based on the fraction of patients assigned to each group.

Correct Answer: B

Rationale: To find the percentage of trips that are the longest route, divide the number of longest route trips (3) by the total number of trips (9) and multiply by 100. So, (3/9) * 100 = 33.33% ≈ 33% which corresponds to choice B. Option A (0.25) is incorrect as it represents 25%, not 33%. Option C (0.5) represents 50%, which is incorrect as well. Option D (0.75) represents 75%, which is also incorrect.

Correct Answer: A

Rationale: To find the percentage of the total staff that is certified and available to work in the neonatal unit during the holiday, we need to multiply the percentages of staff available and certified. First, calculate the percentage of staff available: 100% - 35% (staff on vacation) = 65% available. Then, calculate the percentage of staff certified among those available: 65% (staff available) * 20% (certified) = 13%. Therefore, the correct answer is B: 0.13, representing 13% of the total staff that is certified and available to work in the neonatal unit during the holiday. The other choices are incorrect because they do not accurately represent the calculated percentage.
