Answer:
35 students
Step-by-step explanation:
So if every 3 boys there is 4 girls you can solve that there is 5 times the amount of girls to get to 20. So to solve for the boys you do the same.
3 x 5 = 15
That means there are 15 boys and 20 girls but we want to know the total so what you do is just add 15+20=35
So 35 total students.
Hope that helps and have a great day!

Answer:
V = 549.5 ft³
Step-by-step explanation:
The formula for the volume, V, of a cylinder of radius r and length h is
V = πr²h.
Substituting 2.5 ft for r and 28 ft for h, we get the volume
V = 3.14(2.5 ft)²(28 ft), or
V = 549.5 ft³
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
Hope it helps!
