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
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).

Answer:
72 different sundaes
Step-by-step explanation:
We can find the number of different sundaes by
6 different types of ice cream* 3 different types of sauces *4 different types of toppings
6*3*4 = 72 different sundaes
Round the hight and then the weight and c what you get
