1. A and D, since they both fill the shape with tiles of the same size.
2. 9 square feet, since you just count the number of gray tiles.
This is a geometric series, 0th term 5, common factor 0.5, so
y = 5 (0.5)ˣ
Check: f(0)= 5, f(1) = 5(.5)=2.5, f(2) = 5(.5)² = 1.25, f(3)=5(.5)³=0.625
Answer: y = 5 (0.5)ˣ
8.50 / 12 = 0.708 rounded to the nearest cent = 71 cents (0.71)
Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is 
. With r=50, 
=2500π which is about (2500)(3.14)=7850.
The perimeter is 
which is the same as (diameter)(π). The diameter is 100, so 
which is about (100)(3.14)=314.
C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.
