ATI TEAS Math Practice Test

Correct Answer: C

Rationale: To determine the correct answer, we use the ratio of mg to mL in the concentrated drops. 80 mg is in 0.8 mL, so the concentration is 100 mg per 1 mL. Since the child needs 240 mg, we divide 240 by 100 to find the volume needed, which is 2.4 mL. Therefore, the correct answer is C. Choice A (0.8 mL) is incorrect because that is the original volume, not the calculated dosage. Choice B (1.6 mL) is incorrect as it is half the correct dosage, not the full dosage of 240 mg. Choice D (3.2 mL) is incorrect as it is double the correct dosage, exceeding the required 240 mg for the child.

Correct Answer: C

Rationale: To find the number of students who will complete the nursing program, we first calculate the number of students majoring in nursing: 100 students * 3/4 = 75 nursing majors. Then, we determine how many of these nursing majors will complete the program: 75 nursing majors * 1/5 = 15 students. Therefore, the correct answer is C (15). Choice A (75) is incorrect because it represents the total number of nursing majors, not the number completing the program. Choice B (20) is incorrect as it does not consider the completion rate. Choice D (5) is incorrect as it is too low and does not account for the proportion of nursing majors who actually complete the program.

Correct Answer: C

Rationale: To find the number of data analysis problems, first, determine the total ratio parts: 4 + 2 = 6. Then, calculate the number of parts for algebra problems: 2/6 * 18 = 6. Finally, find the number of data analysis problems: 4/6 * 18 = 12. Therefore, the correct answer is C (36). Option A (24) is incorrect as it miscalculates the ratio. Option B (28) and Option D (38) do not consider the given ratio and total number of algebra problems.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. The total cost is directly proportional to the number of hours rented. 2. The cost per hour is $3.60, so multiplying the number of hours (h) by the cost per hour will give the total cost. 3. Therefore, the equation C = 3.60h correctly represents this relationship. Summary: B: Incorrect, as it incorrectly adds the number of hours to the cost per hour. C: Incorrect, as it unnecessarily adds a fixed cost of $10.80 to the total cost equation. D: Incorrect, as it incorrectly assumes a fixed cost per hour of $10.80.

Correct Answer: C

Rationale: The perimeter of a hexagon is 6 times the length of one side. So, for a side length of 320 feet, the perimeter is 6 * 320 = 1920 feet. The cost of fencing is $1.75 per foot, so the total cost will be 1920 * $1.75 = $3360. Choice A is incorrect as it does not consider the correct perimeter calculation. Choice B is incorrect as it underestimates the total cost. Choice D is incorrect as it overestimates the total cost.
