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.
Oh and here's an image to help you out
Answer:
1. Base of pyramid; 6 in by 6 in
2. Base of prism; Its dimensions are also 6 in by 6 in, located at the bottom of the house and will not be seen, so it does not require painting.
3. twice the area of the square
4. Area = 228 inches squared
Step-by-step explanation:
For question 4, the area Molly needs to paint is found by adding all the surface areas and subtracting the 2 surfaces that will not be painted: base of pyramid and base of prism (outlined in red). According to the picture, these are both squares with 6 by 6 dimensions.
Step 1. Add all surface areas togetherPrism: 6 surfaces
Surface area = 216 inches sq
Front = 6 x 6 = 36 Back = 6 x 6 = 36Top = 6 x 6 = 36Bottom (base) = 6 x 6 = 36Side = 6 x 6 = 36Other side = 6 x 6 = 36Pyramid: 5 surfaces
Surface area = 84 inches sq
Bottom (base) = 6 x 6 = 36Front triangle = (6 x 4)/2 = 12Back = (6 x 4)/2 = 12Side = (6 x 4)/2 = 12 Other side = (6 x 4)/2 = 12TOTAL surface area: 216 inches + 84 inches = 300 inches sq
Step 2. Subtract surfaces that are NOT being painted300 - base of pyramid - base of prism
300 - 2(36)
300 - 72
228 inches sq

Wendy paints a rectangular wall that is 10.5 feet tall and 9.2 feet wide. What is the area of the wall that she paints?
Answer:
96.6
Step-by-step explanation:
We know that the Area of the rectangle is,
A =Length x width
So the Area of the wall painted by Wendy will be,
A = 10.5 x 9.2 = 96.6
So; the area painted by Wendy will be 96.6 square feet.

What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis
Answer:
B
Step-by-step explanation:
This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

lucie and suzie buy greeting cards. lucie buys 10 more cards than one third of the girls’ total. how many more cards should suzie buy so that she has 10 more cards than two thirds of the girls’ total? assume that lucie does not make any purchases after her initial purchase.
QUICK I NEED AN ANSWER ASAP
Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total
How to determine the number of cards?Represent Lucie's card with L and Suzie's card with S.
So, the total number of cards is:
Total = L + S
Lucie's number of cards can be represented as:
L = 10 + 1/3(L + S)
Multiply through by 3
3L = 30 + L + S
Subtract L from both sides
2L = 30 + S
Divide by 2
L = 15 + 0.5S
Let x represents the additional number of cards.
So, we have:
x + L = 10 + 2/3(L +S)
Substitute L = 15 + 0.5S
x + 15 + 0.5S = 10 + 2/3(15 + 0.5S + S)
Evaluate the sum
x + 15 + 0.5S = 10 + 2/3(15 + 1.5S)
Expand
x + 15 + 0.5S = 10 + 10 + S
Evaluate the sum
x + 15 + 0.5S = 20 + S
Subtract 0.5S from both sides
x + 15 = 20 + 0.5S
Subtract 15 from both sides
x = 5 + 0.5S
The above means that Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total

Find the perimeter and area of the shaded figure below.
Answer:
Perimeter = 12
Area = 8
Step-by-step explanation: For the perimeter add all the sides so the top and bottom is both 2 so 2+2 = 4.
For the sides its both 4 so 4 + 4 = 8.
8 + 4 = 12
So the perimeter is 12.
For area just count all the blue squares and there is 8 squares.
So the area is 8.

Step-by-step explanation:
You can tell if a pair of angles, in this case, is 90° if you see the red box in the corner of the angle.
The pair of angles in the picture are complementary angles, which add up to 90°. Therefore, subtract 35 from 90 to find the value of X which is 55°.

Hello guys! Could someone tell me what is H in the attached question? Please and Thank you!
Answer:
5
Step-by-step explanation:
[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]
hope it helps you<3Answer:
H=5
Step-by-step explanation:
Simplifying the equation
We multiply 2(3H) =6H, so the equation is now 12-6H=-18
Isolating the Variables
Then, we subtract 12 from both sides, giving us -6H = -30
Finding H
Finally, we divide both sides by -6, so H= 5
