Answer:
0.24
Step-by-step explanation:
4/5=0.8
0.8 to the power of 2 or 0.8*0.8= 0.64
2/5=0.4
0.64-0.4= 0.24
We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.
(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60
As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
Y=3
because the slope is basically 0
so any horizontal line would do.
2 is 10% of 20.
2/10 = 1/10 = 10%
Hope this helps!
