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
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

Jackson has a cube. Each edge of the cube is 5 centimeters long, as shown below.
Part A
Jackson paints every face of the cube. What is the total surface area, in square centimeters, of the cube
Jackson paints? Be sure to show your work and explain your reasoning.
Part B
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Part C
Jackson has a second cube identical to the first. He cuts off the triangular prism as shown below and throws
it away.
What is the volume, in cubic centimeters, of the remaining solid? Show or explain all your work.
Answers
Answer:
Part A- Surface area = 150cm squared
Step-by-step explanation:
First you find the area of one side of the cube-
side length (5) x side length (5) = area (25)
25 is the area of one side of the cube.
Then you multiple the area of one side (25) by the amount of sides that there are (6)-
25 x 6 = 150

What is the probability of getting exactly 2 tails?
Enter your answer as a reduced fraction, like this: 3/14
Answers
Answer:
or 2/3
Step-by-step explanation:
because two flips out of 3 all together is 2/3
So to get 2 tails we could have gotten:
H T T
T T H
T H T
— P( H T T) = 0.5 x 0.5 x 0.5 = 0.125
— P(T T H) = 0.5 x 0.5 x 0.5 = 0.125
— P(T H T) = 0.5 x 0.5 x 0.5 = 0.125
0.125 + 0.125 + 0.125 = 0.375 = 3/8

So how I did it tbh I went everywere with this but I went backwards because the how you find the mean of something is adding all the values and then dividing them by the number of values(40+41+42+45+45+48+54=315, 315divided by 7=45) but anyway 45x7(because multiplication is the opposite of division)that equals 315-232 which is the answer to 40+45+48+54+45 which were the numbers that were given

Answers
Answer: 35°
Step-by-step explanation:
Step #1: Write the 'triangle sum theorem' for the triangle which is:m∠A + m∠B + m∠C = 180°
Step #2: Substitute the given angle measures40° + 105° + m∠C = 180°
Step #3: Simplify.m∠C + 145° = 180°
Subtract 145° from both sides.
m∠C = 35°
So, the measure of the missing angle (x) is 35°.
