Answer:
There are 9 boys and 12 girls in mrs Clark's class
Step-by-step explanation:
We are given that mrs Clark has 21 students, of which 3/7 are boys
In order to find the number of boys, we multiply 21 by 3/7 which results in 9
This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12
therefore there are 9 boys and 12 girls in mrs Clark's class

Step-by-step explanation:
Because Zachary earns $5 per hour, and he makes a $20 bonus.
His equation is shown in red on the graph, y = 5x + 20.
Maisy earns $7.50 per hour, and she makes a $5 bonus.
Her equation is shown in blue on the graph, y = 7.50x +
5.
After how many hours do they earn the same amount of
money? Where do you see this on the graph? Share

To find the area of a trapezoid, it’s 1/2(base 1 + base 2) x height.
so in this case, base 1 is 16 (add 12+2+2) (the top one) and base 2 is 12 (the bottom one) and the height is 9.
you input all the values in the formula and you get 126in.
hope this helped:)
The first one is fraction and the second one is volume.
