Practice Math TEAS TEST

Correct Answer: D

Rationale: To find the cost of 1 syringe, divide $660 by 55 (55 syringes in a box) = $12 per syringe. To find the cost of 4 syringes, multiply $12 by 4 = $48. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not correctly calculate the cost based on the given information.

Correct Answer: D

Rationale: To calculate a 10% tip on a $28.40 bill, you multiply $28.40 by 0.10, which equals $2.84. Rounding up to the nearest dollar gives an estimated gratuity of $3.00. Choice D is correct because it accurately represents a 10% tip on the bill. Choices A, B, and C are incorrect as they do not reflect the correct calculation for a 10% tip on the given bill amount.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.

Correct Answer: A

Rationale: To find the length of the unknown leg, we can use the Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of a right triangle. Given a = 9 feet and c = 19 feet, we can solve for b: 9^2 + b^2 = 19^2 81 + b^2 = 361 b^2 = 280 b ≈ √280 ≈ 16.7 feet Therefore, the correct answer is A (16.7 feet). Choice B (16.0 feet) is incorrect as it does not account for rounding to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value.
