Q23Convert the fraction $$\frac{1}{5}$$ into a percentage.
✓ Correct answer: C. 20%
Answer: 20% A fraction can be converted to a percent by dividing the numerator by the denominator, multiplying by 100, and adding a percent sign. For $$\frac{1}{5}$$: $$\frac{1}{5} \times 100 = 20%$$
Q24A hospital employed 200 nurses. Out of these, 70 were on the night shift and the rest were on the day shift. What is the ratio of nurses on the night shift to nurses on the day shift?
✓ Correct answer: B. $$7:13$$
Answer: $$7:13$$ There were 200 nurses in all. Of these, 70 were on the night shift, so subtract this amount from the total number to find out how many were on the day shift. $$200 - 70 = 130$$ The ratio of nurses on the night shift to nurses on the day shift is $$70:130$$, or $$70/130$$. Simplify the fraction by dividing the numerator and denominator by 10. $$\frac{70}{130} \div \frac{10}{10} = \frac{7}{13}$$
Q25Calculate: 8 - $$\frac{9}{3}$$
✓ Correct answer: A. 5
Correct answer: 5 PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) dictates the order of operations. Division should be performed before subtraction. 8 - $$\frac{9}{3}$$ 8 - 3 = 5
Q26Solve for z: $$2x + z = 16$$ $$z - x = 8$$
✓ Correct answer: D. $$\frac{32}{3}$$
Answer: $$\frac{32}{3}$$ Use substitution to solve the system of linear equations. Substitute $$x = z - 8$$ into the first equation and solve for z. $$2(z - 8) + z = 16$$ $$2z - 16 + z = 16$$ $$3z - 16 = 16$$ $$3z = 32$$ $$z = \frac{32}{3}$$
Q27Determine the value of $$x$$ in the equation below: $$\frac{x}{3} + \frac{1}{6} = \frac{5}{12} - \frac{2x}{3}$$
✓ Correct answer: B. $$x = \frac{1}{4}$$
Answer: $$x = \frac{1}{4}$$ $$\frac{x}{3} + \frac{1}{6} = \frac{5}{12} - \frac{2x}{3}$$ The common denominator in this equation is 12, so convert all fractions. $$\left(\frac{x}{3} \times \frac{4}{4}\right) + \left(\frac{1}{6} \times \frac{2}{2}\right) = \frac{5}{12} - \left(\frac{2x}{3} \times \frac{4}{4}\right)$$ $$\frac{4x}{12} + \frac{2}{12} = \frac{5}{12} - \frac{8x}{12}$$ Rearrange to group common terms. $$\frac{4x}{12} + \frac{8x}{12} = \frac{5}{12} - \frac{2}{12}$$ Solve the equation $$\frac{12x}{12} = \frac{3}{12}$$ $$x = \frac{1}{4}$$
Q28An electric car charges at a constant rate of 22 kilowatts per hour. If the battery capacity is 440 kilowatt-hours, how many hours will it take to fully charge the battery starting from empty?
✓ Correct answer: C. 20 hours
Answer: 20 hours First, find the total number of hours it will take to charge the battery to 440 kilowatt-hours. $$\frac{22 \text{ kilowatts}}{1 \text{ hour}} = \frac{440 \text{ kilowatt-hours}}{x \text{ hours}}$$ $$22 = \frac{440}{x}$$ $$22x = 440$$ $$x = 20 \text{ hours}$$
Q29A car travels at a constant speed of 60 miles per hour. If the driver starts driving at 2:00 p.m., which of the following is the best estimate of when the car will have traveled 150 miles?
✓ Correct answer: B. 4:30 p.m.
Set up a proportion to find out how many hours it will take to travel 150 miles at 60 miles per hour. $$\frac{60\ \text{miles}}{1\ \text{hour}} = \frac{150\ \text{miles}}{x\ \text{hours}}$$ $$60x = 150$$ $$x = 2.5\ \text{hours} = 2\ \text{hours} + 30\ \text{minutes}$$ Add 2.5 hours to 2:00 p.m. to get 4:30 p.m. Of all the answer choices, 4:30 p.m. is the closest option.
Q30Convert the fraction $$\frac{15}{500}$$ to a percentage.
✓ Correct answer: C. 3%
The correct answer is 3%. To convert a fraction to a percentage, divide the numerator by the denominator, multiply the result by 100, and add a percent sign. $$\frac{15}{500} = 0.03$$ $$0.03 \times 100 = 3\%$$
