Answer:
6 7/8 inches
Step-by-step explanation:
The first thing to do is to get the measurements in either inches or feet. You can't have both. Let's go from feet to inches.
3 feet = 36 inches
13.75 feet = 165 inches
Now we can set up a proportion to solve for the number of inches the model is:
Now we can cross multiply:
36x = 247.5 so
x = 6.875 or 6 7/8 inches
Answer:
70percent =42
100percent ×42 ÷70
100/7×42
10/7×42=60
therefore the original cost was $60
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1).
Hopefully my explanation was clear?
