Aclass had 11 boys and 9 girls in it. what percent of the class are boys?
a. 11%
b. 45%
c. 55%
d. 82%

Hello There, the answer is C. 55%!

To solve, get the total (11 boys + 9 girls = 20 total students). Put the number of boys over the total, representing it as a fraction, 11/20. Now convert this t  a precent by dividing 11 by 20 and multiplying the result by 100.

11 divided by 20 = 0.55

0.55 times 100 = 55%

So, 55% is your final answer. I hope this helps and have a great day!

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
