Answer:

m\angle EFG =69\degree

Step-by-step explanation:

m\angle EFG =\frac{1}{2}(191- 53)\degree

m\angle EFG =\frac{1}{2}\times 138\degree

m\angle EFG =69\degree

Find the distance between the points (3, 8) and (0,4).
Bingel [31]

Answer:

5

Step-by-step explanation:

(3,8) (0,4)

X1 = 3    X2 = 0

Y1 = 8    Y2 = 4

D=\sqrt{(X1-X2)^{2}+ (Y1-Y2)^{2}  }

D= \sqrt{(3-0)^{2} + (8-4)^{2} }

Do what's in the parentheses so...

  1. 3-0= 3
  2. 8-4= 4

Now plug it in!

D= \sqrt{(3)^{2}+(4)^{2}  }

Now you are going to finish the parentheses so...

  1. (3)^2= 9
  2. (4)^2= 16

Plug that in so that you have this...

\sqrt{9+16}

Add 9+16 to get...

\sqrt{25}

Then you are going to find the number or numbers that make this a perfect square...

\sqrt{25}= 5

So 5 is your answer

lisabon 2012 [21]

Answer:

a. If the area of the tiles is greater than or equal to the area of all the rooms.

b. 24

c. 360

Step-by-step explanation:

a. Explain how you would estimate whether Ted has enough tiles to cover all the kitchen floors in the entire apartment building?

Ted would have enough tiles if the  area of the tiles is greater than or equal to the area of all the rooms. Since we have 500 one meter square tiles, we have 500 m² of tiles.

Since the rooms are 6 m long and 4 m wide, the area of each room is 6 m × 4 m = 24 m². Since there are 15 rooms, the area of all the rooms is 15 × 24 m² = 360 m².

Since the area of the tiles = 500 m² is greater than the area of the rooms = 360 m², Ted would have enough tiles to cover all kitchen floors in the entire apartment building.

b. How many tiles, each measuring 1 square meter, are needed to cover one room floor?

Since the area of each room floor is 24 m² and the area of each tile is 1 m², so the number of  1 square meter tiles needed to cover each floor is n = area of floor/area of tile = 24 m²/1 m² = 24.

c. How many tiles are needed to cover all the floors in the entire building?

Since 24 tiles are needed to cover each floor and there are 15 rooms in the building, we would require 24 tiles/room × 15 rooms/building = 360 tiles.

So we require 360 tiles.
