Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 square inches and the surface area of the pyramid is 84 square inches.
1. Which surface is shared by the two solids? What are the dimensions of this surface?
2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.
3. To find the area Molly needs to paint, she should add the surface areas of both solids and subtract:
twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square
4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.

Answers
Answer:
1. a square which is 6 × 6in
2. the inside of the prism or cube as it is not seen from the outside
3. the area of the square - 6 × 6 = 36in
4. 6 x 6 = 36 / one face of prism
× 5 = 180
4 × 6/2 = 12 / one face of pyramid
x 5 = 60
60 + 180 = 240

alan would take 5 hours to build the wall of a house, and gavin would take 7 hours to build it alone. when they work together, they talk a lot, and their combined output decreases by 26 bricks per hour. working together, they build the wall in 4 hours. how many bricks are in the wall?
Answers
Answer:
96 bricks
Step-by-step explanation:
Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour
Together, 12/35 of the job should be done in an hour. In [tex]2 \frac{11}{12}[/tex] hours, the work should be done.
rate at 4 hours=[tex]2 \frac{11}{12}[/tex]*(normal speed-26)
To clarify, x=the normal rate
4 hours(normal rate-26)=[tex]2 \frac{11}{12}[/tex](normal rate)
4(x-26)=[tex]2 \frac{11}{12}[/tex]x
x=96

Answer:
The answer is 23 because they have to add up to 90-kai :)
Step-by-step explanation:
So, ∠a + ∠b = 90°
67° + ∠b = 90°
∠b = 90° - 67°
∠b = 23°
Answer:
The measure of ∠b is 23°.
Step-by-step explanation:
Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:
∠a + ∠b = 90°
∠a = 67°
You can apply this information to the equation by getting the problem of:
67° + ∠b = 90°
To solve this equation you simply rearrange the terms, and subtract 67 from 90:
90° - 67° = ∠b
After rearranging the terms and subtracting 67 from 90 you are left with the following result:
∠b = 23°

Step-by-step explanation:
The smiley face has a radius of 8 centimeters.
We need to find the area of the smiley face.
The formula to find the area of a circle is:
A = [tex]\pi[/tex]r²
A = (3.14)(8)(2)
A = (25.12)(2)
A = 50.24
The area of the smiley face would be 50.24 square feet.
