TEAS Math 3 — Questions and Answers
Question 1: A nurse needs to administer 0.75 liters of IV fluid over 5 hours. How many milliliters per hour should be given?
- 100 mL/hr
- 125 mL/hr
- 150 mL/hr (Correct answer)
- 175 mL/hr
Correct answer: 150 mL/hr
0.75 L = 750 mL; 750 ÷ 5 = 150 mL/hr.
Question 2: Simplify: (3x²y)(4xy³)
- 7x³y⁴
- 12x³y⁴ (Correct answer)
- 12x²y³
- 7x²y³
Correct answer: 12x³y⁴
Multiply coefficients (3×4=12) and add exponents for like bases: x^(2+1)=x³, y^(1+3)=y⁴.
Question 3: A recipe requires 2⅓ cups of flour. If you want to make 1.5 times the recipe, how many cups of flour do you need?
- 3 cups
- 3¼ cups
- 3½ cups (Correct answer)
- 3¾ cups
Correct answer: 3½ cups
2⅓ = 7/3; 7/3 × 3/2 = 21/6 = 7/2 = 3½ cups.
Question 4: What is the median of the data set: 14, 9, 22, 17, 5, 11, 22?
- 14 (Correct answer)
- 17
- 11
- 22
Correct answer: 14
Ordered: 5, 9, 11, 14, 17, 22, 22 — the middle (4th) value is 14.
Question 5: A car travels 264 miles on 8 gallons of gas. At the same rate, how many gallons are needed to travel 396 miles?
- 10 gallons
- 12 gallons (Correct answer)
- 14 gallons
- 16 gallons
Correct answer: 12 gallons
Rate = 264/8 = 33 mpg; 396 ÷ 33 = 12 gallons.
Question 6: Which expression is equivalent to 5(2x − 3) − 2(x + 4)?
- 8x − 23 (Correct answer)
- 8x − 7
- 8x + 7
- 12x − 23
Correct answer: 8x − 23
5(2x−3)−2(x+4) = 10x−15−2x−8 = 8x−23.
Question 7: A triangle has sides of length 7, 24, and 25 cm. What type of triangle is it?
- Acute
- Obtuse
- Right (Correct answer)
- Equilateral
Correct answer: Right
7² + 24² = 49 + 576 = 625 = 25², satisfying the Pythagorean theorem.
