Answer:

52.8 feets

Step-by-step explanation:

From the diagram :

The height of tree woulb be :

Height above the ground (at breakpoint) + hypotenus

Hypotenus, h cab be obtained using Pythagoras rule :

h² = opp² + adj²

h² = 39² + 12²

h² = 1665

h = sqrt(1665)

h = 40.804 feets

Height of tree to the nearest tenth ;

40.804 feets + 12 feets

= 52.804 feets

= 52.8 feets

a worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. THe tiles are square with side lengths 1 1/3 feet
Genrish500 [490]

Answer:

102 tiles needed to cover the entire floor.

Step-by-step explanation:

Given : A worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. The tiles are square with side lengths 1\frac{1}{3} feet.

To find : How many tiles are needed to cover the entire floor?    

Solution :

A rectangular room that is 12 feet by 15 feet.

The area of the room is A=L\times B

A_r=15\times 12

A_r=180\ ft^2

The tiles are square with side lengths 1\frac{1}{3}=\frac{4}{3} feet.

The area of the tile is A_t=s^2

A_t=(\frac{4}{3})^2

A_t=\frac{16}{9}\ ft^2

Number of tiles needed to cover the entire floor is

n=\frac{A_r}{A_t}

n=\frac{180}{\frac{16}{9}}

n=\frac{180\times 9}{16}

n=101.25

Therefore, Approximately 102 tiles needed to cover the entire floor.
