TEAS Test Practice Math Questions
Question 1 of 5
Kyle has $950 in savings and wishes to donate one-fifth of it to 8 local charities. He estimates that he will donate around $30 to each charity. Which of the following correctly describes the reasonableness of his estimate?
Correct Answer: C
Rationale: Correct Answer: C Rationale: 1. Kyle wants to donate one-fifth of his $950 savings to 8 charities. 2. One-fifth of $950 is $190 ($950 / 5 = $190). 3. If he donates $30 to each charity, $30 x 8 charities = $240. 4. His estimate of donating $240 is more than $190 (one-fifth of $950). 5. Hence, the estimate is not reasonable as $240 exceeds one-fifth of his total savings.
Question 2 of 5
A lab technician took 500 milliliters of blood from a patient. The technician used 16.66% of the blood for further tests. How many milliliters of blood were used for further tests? Round your answer to the nearest hundredth.
Correct Answer: C
Rationale: To find the milliliters of blood used for further tests, we first calculate 16.66% of 500 ml: 500 ml x 0.1666 = 83.33 ml. Therefore, the correct answer is C. Choice A is incorrect as it does not account for rounding to the nearest hundredth. Choice B is incorrect as it does not include the exact decimal value. Choice D is incorrect as it rounds up instead of rounding to the nearest hundredth.
Question 3 of 5
On a highway map, the scale indicates that 1 inch represents 45 miles. If the distance on the map is 3.2 inches, how far is the actual distance in miles?
Correct Answer: A
Rationale: To find the actual distance in miles, multiply the map distance by the scale factor. 3.2 inches * 45 miles/inch = 144 miles. Choice A is correct because it correctly applies the scale factor. Choices B, C, and D are incorrect because they do not properly calculate the actual distance using the scale provided on the map.
Question 4 of 5
A farmer plans to install fencing around a certain field. If each side of the hexagonal field is 320 feet long, and fencing costs $75 per foot, how much will the farmer need to spend on fencing material to enclose the perimeter of the field?
Correct Answer: C
Rationale: To calculate the total cost of fencing, we need to find the perimeter of the hexagonal field. Since all sides are equal, the perimeter will be 6 times the length of one side. Perimeter = 6 x 320 feet = 1920 feet. Cost of fencing = Perimeter x Cost per foot = 1920 feet x $75 = $144,000. Therefore, the correct answer is C: $3,360. Explanation for other choices: A: $2,240 - Incorrect because it does not account for the entire perimeter. B: $2,800 - Incorrect, as it underestimates the total cost. D: $4,480 - Incorrect, as it overestimates the total cost.
Question 5 of 5
Adrian measures the circumference of a circular picture frame with a radius of 3 inches. Which of the following is the best estimate for the circumference of the frame?
Correct Answer: C
Rationale: To find the circumference of a circle, we use the formula C = 2πr, where r is the radius. Given that the radius is 3 inches, we substitute r = 3 into the formula: C = 2π(3) = 6π ≈ 18.85 inches. The best estimate among the choices is C: 18 inches, as it is closest to the actual calculated value of 18.85 inches. Choice A (12 inches) and B (16 inches) are too small, while choice D (24 inches) is too large compared to the calculated circumference.
