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:
This is the same as saying 18*sqrt(2) or you could say 18√2
============================================================
Explanation:
We'll be using this square root rule:
So we could have this as our steps:
Therefore,
The basic idea is to first combine the roots using that rule. From there, we factor the radicand such that we pull out the largest perfect square factor. This will allow us to break the root apart and fully simplify it.
