TEAS Practice Math Test
1. A gift box has a length of 14 inches, a height of 8 inches, and a width of 6 inches. How many square inches of wrapping paper are needed to wrap the box?
- A. 56
- B. 244
- C. 488
- D. 672
Correct answer: C
Rationale: To find the surface area of a rectangular prism, you use the formula SA = 2lw + 2wh + 2hl, where l is the length, w is the width, and h is the height. Substituting the given dimensions, the calculation would be SA = 2(14)(6) + 2(6)(8) + 2(8)(14) = 168 + 96 + 224 = 488 square inches. Therefore, 488 square inches of wrapping paper are needed to wrap the box. Choice A (56), Choice B (244), and Choice D (672) are incorrect because they do not represent the correct surface area calculation for the given box dimensions.
2. Solve this equation: 2x+8=0
- A. -4
- B. 3
- C. 5
- D. 0
Correct answer: A
Rationale: To solve 2 ๐ฅ + 8 = 0 2x+8=0: Subtract 8 from both sides: 2 ๐ฅ = โ 8 2x=โ8 Divide both sides by 2: ๐ฅ = โ 8 2 = โ 4 x= 2 โ8 โ =โ4 Therefore, the solution is ๐ฅ = โ 4 x=โ4.
3. Simplify the following expression: 5/9 ร 15/36
- A. 5/36
- B. 8/27
- C. 10/17
- D. 15/27
Correct answer: A
Rationale: To simplify the given expression, multiply the numerators together and the denominators together. 5/9 ร 15/36 = (5 ร 15) / (9 ร 36) = 75 / 324. Now, simplify the resulting fraction by finding the greatest common divisor (GCD) of 75 and 324, which is 3. Divide both the numerator and denominator by 3 to get the simplified fraction: 75 รท 3 / 324 รท 3 = 25 / 108. Therefore, the simplified form of 5/9 ร 15/36 is 25/108, which is equivalent to 5/36. Choice A, 5/36, is the correct answer. Choice B, 8/27, is incorrect as it does not match the simplified form of the expression. Choice C, 10/17, is unrelated and does not result from the given multiplication. Choice D, 15/27, does not correspond to the simplification of the given expression.
4. Shawna buys 5 gallons of paint. If she uses 2/5 of it on the first day, how much paint does she have left?
- A. 3 gallons
- B. 2 gallons
- C. 1 gallon
- D. 0.5 gallons
Correct answer: A
Rationale: To find out how much paint Shawna uses on the first day, calculate 2/5 * 5 = 2 gallons. Subtracting the amount used from the total amount gives us 5 - 2 = 3 gallons remaining. Therefore, Shawna has 3 gallons of paint left after using 2 gallons on the first day. Choice A is correct. Choices B, C, and D are incorrect because she has more paint left than the options presented.
5. There are 800 students enrolled in four allied health programs at a local community college. The percentage of students in each program is displayed in the pie chart. What is the number of students enrolled in the respiratory care program?
- A. 336
- B. 152
- C. 144
- D. 168
Correct answer: B
Rationale: To find the number of students enrolled in the respiratory care program, you need to calculate 19% of 800. 19% of 800 is (19/100) * 800 = 152 students. Therefore, the correct answer is B. Choice A (336), Choice C (144), and Choice D (168) are incorrect as they do not represent the correct percentage of students enrolled in the respiratory care program as indicated by the pie chart.
