Answer:

300

Step-by-step explanation:

x girls / 500 students

18/30 = x/500

x = 18/30 x 500

x= 300 girls

Therefore there are approximately 300 girls in the school.

Tresset [83]

Answer:

8

Step-by-step explanation:

Hello,

This is related to ratios and proportions. We have a 12 foot tree that casts a 6 foot shadow, so now we are trying to figure out how tall is a tree that casts a 4 foot shadow.

We can set an easier method to get this.

12 = 6 (this means the 12 foot tree casts a 6 foot shadow)

x = 4 (this means how tall is the tree to cast a 4 foot shadow, the unknown height of the tree is denoted as x)

Then, we can cross multiply.

48 = 6x

Solve for x, which is the unknown height we are trying to figure out.

x = 8
