Practice Math TEAS TEST

Correct Answer: A

Rationale: To correctly order the numbers from least to greatest, we start by comparing the negative numbers first. The most negative number is -271.906, followed by -193.823. Then, we move on to the positive numbers, starting with 145.884 and ending with 235.971. Therefore, the correct order is -271.906, -193.823, 145.884, 235.971 (Option A). Choice B is incorrect because it incorrectly places 235.971 before -193.823. Choice C is incorrect as it places 145.884 before -193.823. Choice D is incorrect because it swaps the positions of -193.823 and -271.906.

Correct Answer: A

Rationale: The correct answer is A: 2W + 2(W + 3). To find the perimeter of a rectangle, you add up all its sides. Given that the length is 3 units greater than the width, the length is represented as W + 3. So, the expression for the perimeter is 2W (for the width) + 2(W + 3) (for the length). This simplifies to 2W + 2W + 6, which further simplifies to 4W + 6, representing the correct perimeter expression. Summary: B: W + W + 3 is incorrect as it only adds the width twice and does not account for the length. C: W(W + 3) is incorrect as it represents the area of the rectangle, not the perimeter. D: 2W + 2(3W) is incorrect as it incorrectly combines the width and length terms in the expression.

Correct Answer: D

Rationale: To find the correct answer, we first calculate how much of the burger was left after one friend ate a quarter (3/4 left). Then, the other two friends divide this among themselves equally, so each receives half of the remaining portion (3/4 * 1/2 = 3/8). Therefore, each of the other two friends received 3/8 of the burger, which is represented by choice D (8-Mar). Choices A, B, and C are incorrect because they do not accurately reflect the correct calculation of dividing the remaining portion equally between the two friends.

Correct Answer: C

Rationale: To convert 45 kg to pounds, multiply by the conversion factor 2.2 lbs/kg. So, 45 kg * 2.2 lbs/kg = 99 lbs. Therefore, the correct answer is C. Choice A (120 lbs) is incorrect as it is not the result of the conversion calculation. Choice B (89 lbs) is also incorrect as it does not match the conversion result. Choice D (90 lbs) is incorrect because the correct equivalent weight is 99 lbs, not 90 lbs.
