Answer:
The answer is 238 :)
Step-by-step explanation:
Your answer is
4.7Using the Pythagorean Theorem, you can find the length of the missing side:

Length cannot be negative, so your answer is:
1/4 = .25 or 25%
a(postcard stamps) = .25(percentage of postcard stamps) * 900(total of stamps)
900 * .25 = 225
They sold 225 postcard stamps
To check:
225 * 4 = 900
Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:
18(0.25)=k=4.5
So you could say: IR=4.5 or I=4.5/R
