4/11=36.36%
..............
80% = 0.80
divide the area done by the percentage:
920/0.80 = 1150
total area is 1150 square feet
Answer:
The top left answer is correct.
Step-by-step explanation:
If you take each ordered pair and put them in the form y/x. The top left corner is the only one where all of the equations are equivalent.
7/1 = 21/3 = 35/5 = 49/7
Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80
10^x=39 this is exponential form.
