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.

Answer:
Area= 372
Step-by-step explanation:
The area of a trapezoid is
[tex]\frac{a+b}{2} * h[/tex], where a is the top base, and b is the bottom base.
A is 7, B=24
h, the height, is the height, which is perpendicular to the bases. The height is 24.
Plug it into the equation,
31/2 * 24 is 372.
Area= 372
Step-by-step explanation:
The area of a trapezoid is
*** h, where a is the top base, and b i.
A is 7, B=24
h, the height, is the height, which is
perpendicular to the bases. The height is

3. Find Each Angle Measure
Answers
Answer:
m1=125 degrees
m2=55 degrees
m3=55 degrees
m4=125 degrees
m5=125 degrees
m6=55 degrees
m7=55 degrees
Step-by-step explanation:
becoz the image thing says m8 is 125 degrees
and that just gave us the answer for measures 5, 4, and 1 because a is parallel to b so thats why you can see that all of the measures are all the same
now for 2, 3, 6, and 7 we needa find those righht?
remember full circle is 360 degrees and we know measures 4 and 1 is 125 degrees,
so all we gotta do is add them which is 250 degrees and subtract from 360 degrees
360-250 = 110 degrees
ok now divide by 2 since were lookink for 2 and 3 not 2 and 3 combined
110/2=55 degrees
and boom all of those angles are the same for 5, 6, 7, and 8
please help! I'm so confused on this. Ill give brainliest if you can figure these out.

Lauren recorded the price of a gallon of milk at two grocery stores for four weeks.
show your work!!
On average, which grocery store had a better price for milk and by how much?
Discount Mart by $0.08 per gallon
Super Store by $0.08 per gallon
Discount Mart by $0.40 per gallon
Super Store by $0.40 per gallon
Answers
Hi,
Discount Mart:
2.99 + 3.19 + 3.55 + 3.05= 12.78
12.78 ÷ 4= 3.195
The average price of milk at Discount Mart is 3.195$
Super Store:
3.19 + 2.79 + 2.99 + 3.49= 12.46
12.46 ÷ 4= 3.115
The average price of milk at Super Store is 3.115$
3.195 - 3.115= 0.08
Therefore we can see that Super Store had a better price on average than Discount Mart by 8 cents.
Your final answer is: "Super Store by $0.08 per gallon"
Hope I could help~ have a good day/night :]
average = values / # of values
average for Discount Mart = $2.99 + $3.19 + $3.55 + $3.05 / 4 = $12.78 / 4 = $3.20 on average
average for Super Store = $3.19 + $2.79 + $2.99 + $3.49 / 4 = $12.46 / 4 = $3.12
$3.20 > $3.12
$3.20 - $3.12 = $0.08 or 8 cents
Discount Mart > Super Store
Super Store had a cheaper price for milk by $0.08 per gallon on average.
