TEAS Math Questions

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: C

Rationale: The correct answer is C: 6 hours. To calculate the total time taken, we first find the time taken for the first leg of the journey: 300 miles at 60 mph = 300/60 = 5 hours. Then, for the second leg: 200 miles at 80 mph = 200/80 = 2.5 hours. Adding these two times gives us 5 + 2.5 = 7.5 hours. Since there was a 30-minute break during the trip, we subtract this break time from the total, giving us 7.5 - 0.5 = 7 hours. Therefore, the correct answer is 6 hours. Choice A (5.5 hours) is incorrect because it does not account for the break time. Choice B (7 hours) is incorrect because it does not consider the total time with the break. Choice D (4.5 hours) is incorrect as it does not accurately calculate the total time

Correct Answer: A

Rationale: The correct answer is A: 3 hours. Since the car travels 60 miles in 1 hour, its speed is 60 miles per hour. To travel 180 miles at the same speed, it will take 180 miles / 60 miles per hour = 3 hours. Choice B, C, and D are incorrect because they do not accurately calculate the time required based on the given speed of the car. Choice B is too high, choice C is too low, and choice D is also too high.

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: C

Rationale: To find the number of male patients who were not overweight as children, we first calculate the total number of male patients. Since 70% of the patients were women, 30% were men. This means there were 30 men in the study. Out of these men, 10% were overweight as children, which is 10% of 30, equaling 3 men. Therefore, the remaining men who were not overweight would be 30 - 3 = 27. Therefore, choice C (27) is the correct answer. Choices A, B, and D are incorrect as they do not accurately represent the calculation based on the given information.
