we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
We know, Rectangular Prism(V) = x * y * z
v = 8 * 15 * 7
v = 840
In short, Your Answer would be 840 units³
Hope this helps!
Answer:
It is based on how many decimal places are in the equation.
40.5 /3 = 13.5
2.52 / 0.6=4.2
150.88 / 4= 37.72
1.54 /7 = .22
