Solving for the lateral surface of the square pyramid, we need to use the formula shown below:
Lateral Area = a √ (a² + 4h²) where "a" for the base edge and "h" for the height

We have given values such as:
Base = 12  inches
Height  = 15 inches
Lateral area = 12 √ (12² + 4*15)
Lateral area = 171.39 inches²

The answer is 171.39 inches².

You are running a concession stand at a basketball game. You are selling hot
Nuetrik [128]

x= hot dogs

y= soda

Total sold

1 x + 1 y = 87 .............1

2 x 0.50 y = 78.50 .............2

Eliminate y

multiply (1)by -0.50

Multiply (2) by 1.00

-0.50 x -0.50 y = -43.50

2 x + 0.50 y = 78.50

Add the two equations

1 x = 35.00

/ 1

x = 35.00

plug value of x in (1)

1 x + 1 y = 87

35 + y = 87

y = 87 -35

y = 52

y = 52.00

x= 35 hot dogs

y= 52 soda
