Ed Is Building A Model Of A House With A Flat Roof, As Shown In The Diagram. There Is A Chimney Through

Answers

Answer 1

Answer:

Step-by-step explanation:

3x4

Answer 2
You will need to find the area first so 50in x 40in =2,000in

Then find the area the chimney takes up. 4in x 3in = 12in

2,000in - 12in =1,988 tiles for the roof.

When Sally went bowling, her average scores were 108, 72, and 95 If she bowls a 4th game, what will her score need to be to give her and average of 91?


Pls hurry! I need a full explanation!!

Answers

An average is the sum of the scores divided by the number of games played.

For her average to be 91 after 4 games the total of the scores needs to be 91 x 4 = 364

To find what her 4th score needs to be subtract her first 3 scores from 364

364 - 108 - 72 - 95 = 89

Her 4th game needs to be 89

Her score will need to be 89

what is the value of k ?

Answers

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Find surface area of the pyramid pls!!!!:((((

Answers

Answer:

64 cm^2

Step-by-step explanation:

Since we don't have the height of the prism we just need to find the area of the surface area

the area of the square is 16 cm^2

The area of the triangle is:

6 times 2 is 12 divided by 2 is 6

6 times 8 is 48 cm^2

48 plus 16 is

64 cm^2

Hope this helps!

64cm squared.

find the SA of the bottom square (4x4) and then of the 4 triangles and the answer comes to 64. since the measurements are cm the full answer would be 64 cm^2.
