In preschool there is a ratio of 3 boys for every 4 girls. If there are 24 girls, then how many boy are in class?

Step-by-step explanation:

If there is 3:4 then if we know there is 24 girls then we can fill it in.

3:4=x:24

3/4=x/24

4x=72

x=18

or

we can just do 24 divided by 4 where we get 6 so we just do 3 times 6 which is also 18.

hope this helps

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

it is not that hard all u have to do is plot the graph
