Asquare pyramid has a base area of 64 ft the pyramid's total surface area is 224 ft2 what is the area of each triangular face? a. 32 ft b. 53 1/3 ft c. 40 ft d. 160

So you the area of the square pyramid is 224, and the area contains the base area+ 4*the area of triangle surface.
so we can say, 224=64+4*x where x equals the area of each side of the triangle
160=4*x divide by four 
so x=40 ft squared and the answer would be C

Step-by-step explanation:

The general equation is

y = 2.49x + 24.99

The number of cones bought is x

The cake cost is 24.99

The total cost is y

So the meaning of (5,37.44) is that she bought 5 cones and 1 cake. Let's just check that out.

Check

y = 2.49*5 + 24.99

y = 12.45 + 24.99

y = 37.44

So the total cost (y) of 5 cones (2.49 each) and 1 cake ($24.99) is 37.44
