Answer:

C

Step-by-step explanation:

there is the ground line of about -5.5 to +5.5 = 11 ft.

then the 2 walls of 7 ft height = 14 ft.

that is already 25 ft.

the 2 roof sides are both a little bit longer than the corresponding ground line of 5.5ft.

so, estimated about 6ft per roof side. that adds 12 ft.

so, we are at about 37 ft.

and the closest answer is C. 36 ft.

in actual numbers a roof side is (using Pythagoras) :

roof side² = 2.5² + 5.5² = 6.25 + 30.25 = 36.5

roof side = 6.041522987... ft

so, the actual perimeter is

25 + 2×6.041522987... = 37.08304597... ft

50 points and Ill give brainiest - please help ASAP with WORK FOR IT please and thank you!! :)

Answer:

1) (x + 12)²+(y+6)²= 28

comparing above equation with(x-h)²+(y-k)²=r²

we get

r=√28

h=-12

k=-6

;.centre=(-12,-6)

radius =√28 units

2) x²+(y+7)²=15

comparing above equation with(x-h)²+(y-k)²=r²

we get

r=√15

h=0

k=-7

;.centre=(0,-7)

radius=√15 units

3) (x + 4)²+(y - 1)² = 4

comparing above equation with(x-h)²+(y-k)²=r²

we get

r=√4=2units

h=-4

k=1

;.centre=(-4,1)

radius=√2units

4) (x+3)²+(y-1)²= 8

comparing above equation with(x-h)²+(y-k)²=r²

we get

r=√8=2√2units

h=-3

k=1

;.centre=(-3,1)

radius=2√2units

Hannah has a grid of squares that has 12 rows with 15 squares in each row. She colors 5 rows of 8 squares in the middle of the g
ASHA 777 [7]

Answer:Number of squares colored red= 180-40= 140 squares

Step-by-step explanation:

Hannah has a grid of squares that has 12 rows with 15 squares in each row. This means the length of the gris is 15 squares and the breadth is 12 squares.

Area of grid = length × breadth

=15×12 = 180

She colors 5 rows of 8 squares in the middle of the grid blue. This means the part coloured blue has a length of 8 squares and breadth of 5 squares.

Area of blue colored part = 8×5 = 40

Number of squares colored red= total number of squares - number of square colored blue= 180-40= 140 squares
