Find the surface area of this composite solid.
Nataly_w [17]

Answer: C

Step-by-step explanation:

The surface area of a pyramid = A + 1/2ps

Where A = area of the base

P = perimeter of base

S = slant height.

A = 4 × 4 = 16 m^2

P = 4L = 4 × 4 = 16 m

S = 3m

Surface area = 16 + 1/2 × 16 × 3

Surface area = 16 + 24

Pyramid surface area = 40 m^2

The surface area of the cuboid = LB + 2LH + 2BH

Where

B = width

H = height

L = length

Substitute all the parameters into the formula

Surface area = 4×4 + 2(4×5) + 2(4×5)

Surface area = 16 + 40 + 40

Surface area = 96 m^2

To Find the surface area of this composite solid, you will add the pyramid surface area to the cuboid surface area. That is

Total surface area = 40 + 96 = 136m^2

Therefore, the surface area of this composite solid is 136 cubic meters

A gas station sells regular gas for $2.20 per gallon and premium gas for $3.00 a gallon. at the end of a business day 300 gallon
zaharov [31]
You can use a system of equations to answer this question.

1st:  2.20r + 3p = 700 is showing how to get the total cost.
2nd: r + p = 300 shows how many gallons were sold.

If we solve r + p = 300 for r, we can then solve the first equation in terms of r only.

r + p =300
p = 300 - r  Use this in place of p in the first equation.

2.20r + 3p = 700
2.2r + 3(300 - r) = 700
2.2r + 900 - 3r = 700
       -900            -900
2.2r - 3r = -200
<u>-0.8r </u>= <u>-200</u>
-0.8     -0.8
r = 250 gallons

There were 250 regular gallons sold and 50 premium gallons sold (300 - 250).
