C. The quilt will be made of 30 pinwheel designs. The

material to make the large triangles costs $0.08 per

square inch. How much will it cost to purchase the material to make the triangles for the quilt?

The total cost will be 172.8.

Step-by-step explanation:

To find the price we have to find the area of the triangles which is

4(1/2*b*h)

4(1/2*6*6)

Hence 72 is the area of triangle.

Now find the cost

Multiply all the values to find the cost:

30×0.08×72

$172.8.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

46.2+112.3
