Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
Answer: x=−2

Answer:
large box will hold 48 units.
Step-by-step explanation:
Let the holding capacity of large box = x
According to given scenario:
75% of x = 36
0.75 x = 36
Dividing both sides by 0.75 we get:
x = 36/0.75
x = 48 units
So the large box will hold 48 units.
