ATI TEAS Math Practice Test

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.

Correct Answer: A

Rationale: The correct answer is A: $2,500. To calculate the total monthly earnings, first determine the commission earned on sales: $5,000 * 3% = $150. Add this to the base salary of $2,000: $2,000 + $150 = $2,150. Therefore, the total monthly earnings will be $2,150.

Correct Answer: C

Rationale: To convert kilometers to miles, we can use the conversion factor of 1 kilometer is approximately 0.621 miles. Therefore, to find the distance in miles, we multiply 45 kilometers by 0.621, which equals approximately 28 miles. Choice C is correct because it correctly converts the distance from kilometers to miles. Choice A (42 miles), Choice B (37 miles), and Choice D (16 miles) are incorrect because they do not correctly convert kilometers to miles. Choice A overestimates the distance, Choice B underestimates it, and Choice D significantly underestimates it.

Correct Answer: A

Rationale: To convert 56 kilograms to pounds, we use the conversion factor that 1 kilogram is approximately 2.2 pounds. So, 56 kg x 2.2 = 123.2 pounds. Since we are asked for the approximate weight in pounds, we round it to the nearest whole number, which is 123 pounds. Summary: - A (123 pounds) is correct because it is the accurate conversion of 56 kilograms to pounds. - B (110 pounds), C (156 pounds), and D (137 pounds) are incorrect as they do not correctly convert 56 kilograms to pounds using the conversion factor.

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.
