TEAS Math Questions

Correct Answer: C

Rationale: To determine the number of male patients NOT overweight as children, calculate the total number of male patients: 30% of 100 patients = 30 male patients. Then, find the number of overweight male patients: 10% of 30 male patients = 3 overweight males. Subtract the overweight males from the total male patients to get the number of male patients NOT overweight: 30 - 3 = 27. Therefore, the correct answer is C (27). Choice A (3) is incorrect because it represents the number of overweight male patients, not the number of male patients NOT overweight. Choice B (10) is incorrect as it does not consider the calculation of overweight male patients and total male patients. Choice D (30) is incorrect as it represents the total number of male patients, not the number of male patients NOT overweight.

Correct Answer: C

Rationale: To calculate the correct dosage for the child, we divide the required dosage (240 mg) by the concentration of acetaminophen in the drops (20 mg/mL). This gives us 12 mL as the correct amount. Therefore, the child should receive 2.4 mL (12 mL divided by 5) of concentrated infant drops. Option C is correct because it accurately represents the calculated dosage. Options A, B, and D are incorrect as they do not reflect the correct calculation based on the concentration and required dosage.

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: The correct answer is A. To determine which group has the largest number of patients, we need to find the group with the largest fraction. Comparing 1/2, 1/3, and 1/6, 1/2 is the largest fraction. Therefore, the group represented by 1/2 has the largest number of patients. Summary of other choices: B: Beta - Represents 1/3, which is smaller than 1/2. C: Gamma - Represents 1/6, which is smaller than both 1/2 and 1/3. D: Delta - No fraction is provided, so we cannot compare it to the other groups.

Correct Answer: C

Rationale: To find how many questions the student answered correctly: 1. Calculate 85% of 50: 0.85 * 50 = 42.5 2. Since the student can't answer half a question, round down to the nearest whole number: 42 Therefore, the student answered 42 questions correctly. Option C is correct. Incorrect options: A: 40 questions - Too low, as the student scored above 40. B: 42 questions - Close but not rounded correctly. D: 45 questions - Too high, as the student's score was 85%.
