Answer:
800
Step-by-step explanation:
We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%
Cross multiply and solve:
240 * 100 = 30x
24000 = 30x
800 = x
Answer:
28.26 miles
Step-by-step explanation:
Area= pi times radius squared
diameter is twice the radius so 6÷2=3miles
3 miles is the radius
So A= 3.14 × 3²
= 28.26
Find the proportional relationship in a unit rate.
x:y
Put in x and y.
60:25
Divide both sides by 5.
12:5
So, every 5 units of y, there are 12 units of x.
Put the new y into proportion.
x:30
There are 5 extra units of y.
All you need to do is add 12 to the previous x.
60+12= 72
x=72
I hope this helps!
