Answer:
w = 16.875 inches
Step-by-step explanation:
Given that the ratio of the length to width in a full-size cello is approximately 8 to 3.
This will be a constant for all cellos
Using the above we can find out length if we know width and vice versa.
Here we know the length = 45 inches
Since
BY cross multiplication we find that
8w = 3(45)
Or w = 16.875 inches
Verify:
Let us check our answer by comparing with proportion
l/w = 45/16.875 = 8/3
Hence our answer is right
Answer:
Yes, the table represent a direct variation
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In a direct variation the constant of proportionality k is equal to the slope m of the line <em><u>and the line passes through the origin</u></em>
In this problem , if the table represent a linear function, then the table represent a direct variation
<u><em>Verify</em></u>
For x=3, y=1
Find the value of the constant k of proportionality
---->
For x=6, y=2
Find the value of the constant k of proportionality
---->
For x=9, y=3
Find the value of the constant k of proportionality
---->
The values of k are equal
therefore
The table represent a direct variation
