Answer:
9.9 inches
Step-by-step explanation:
Use the pythagorean Theorem
c^2 = a^2 + b^2
c^2 = 7^2 + 7^2
c^2 = 49 + 49
c^2 = 98
Take the square root of both sides
c = 9.8994949366
Rounded
c = 9.9 inches
We can use algebra.
So, what rate time 1.20 = .80
Let x = the rate (in a decimal form)
1.20x = .80
x = .6666666666
Now, we need to multiply by 100 to get a percentage.
66.66 The price is 66% of the regular price.
They marked it off
33.33%
it would have a range of 6
im guessing that u ment 4 and ten not 104 so ya
