The ratio is 4:5
so girls=4x
and boys=5x
(because you don't know how many boys or girls there are)
then the equation would be
4x+5x=18
9x=18
so x=2
then 2 times 4 which equals 8
and 2 times 5 which equals 10
so there are 8 girls and 10 boys
Answer:
13,5
Step-by-step explanation:
Find the length of the diagonal lines with Pythagorean theorem, and because it is already given that the lengths of the sides of the preformed shape are all equal, graph the 6th point with your information.
The picture is like less than 144p
8.5 + 7.25 = 15.75
16.25 - 15.75 = 0,5
There are 0,5 meters left.

Answer:
21.07
Step-by-step explanation:
The tangent ratio is ...
Tan = Opposite/Adjacent
For the given values, this is ...
tan(36°) = x/29
Solving for x, we have ...
x = 29·tan(36°)
x ≈ 21.07
