<h3>
Answer = 3:1</h3>
==========================================
Work Shown
45 girls : 15 boys
45/15 girls : 15/15 boys .... divide both parts by 15
3 girls : 1 boy
This tells us there are three times as many girls as there are boys.
We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.

Binomial theorem:

The term with

corresponds to

and

(or

, since

).
So, the coefficient of this term is
Answer:
2 Feet
Step-by-step explanation:
The area is found by multiplying length by width. Since its a square the length and width are the same and it would have to be 2.
Answer:
≈ 62.8
Step-by-step explanation:
Using the equal ratios of
=
, that is
=
= 5, thus
5 × sector = 100π ( divide both sides by 5 )
sector = 20π = 20 × 3.14 = 62.8 units²
