Answer:
The number of boys are 64.
Step-by-step explanation:
We have,
The ratio of the boy to girl is 8:9.
Total number of girls are 72.
Let total boys are 8x and total girls are 9x.
According to the question,

Since, number of boys are 8x. So,

So, the number of boys are 64.
In order to calculate this, you need to solve :

x 100 %
= 0.2 / 9.87 x 100 %
= 2.02 %

Answer:
see below
Step-by-step explanation:
4a) x / 12 = 5
multiply both sides of equality by 12
x = 60
4b) Dan charges $12 per hour, this doesn't change so it's the constant of proportionality.
4c) S = 12h
If you substitute the h with the number of hours worked multiply with the constant of proportionality 12 you'll get the amount charge S.
5) Equation for a slope is (y₂ - y₁) / (x₂ - x₁):
(2 - 0) / (6 - 1)
= 2/5
