There's an app called photomath that would be useful for these kinds of problems!
Answer:
Step-by-step explanation:
we have that
The scale drawing is

we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm

For x=80 cm

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
For x=40 cm, y=900
substitute
----->
The equation is
Answer:
y equals 4 because if you substitute solve and isolate you get that answer.
7 is a prime number, which means it can't be simplified. This fraction is already in simplest form, also because 25 and 7 don't have any common factors.
