Answer:
a) 
b) 
Step-by-step explanation:
In both parts of the problem y varies directly as x. So, they have the following form:
Where k is the constant of proportionality.
Therefore, you must find k and then write the equations.
a) Solve for k:
Then, the equation is:
b) Solve for k:
Then, the equation is:
Answer:
192m³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a square based pyramid
The highlighted figure is a square based pyramid
The volume of a pyramid is
V=a²h/3
Where a= base length
h= height
Given a= 8m
h= 9m
Volume = 8²*9/3
Volume = 64*3
Volume = 192m³
