Answer:

The area reserved for the swim team is 600 square feet.

Step-by-step explanation:

Given : A rectangular pool is 40 feet by 20 feet. The portion of the pool that is reserved for recreational swimming is 20 ft by 10 ft. The rest of the pool is reserved for the swim team.

To find : How many square feet are reserved for the swim team?

Solution :

Dimension of a rectangular pool is 40 feet by 20 feet.

The area of the rectangular pool is

A_R=L\times B

A_R=40\times 20

A_R=800 ft.^2

Dimension of a recreational swimming pool is 20 ft by 10 ft.

The area of the recreational swimming pool is

A_r=l\times b

A_r=20\times 10

A_r=200 ft.^2

If we subtract the area of the recreational swimming pool from the total area of rectangular pool we get the area reserved for swim team.

A_R-A_r=800-200=600 ft.^2

Therefore, The area reserved for the swim team is 600 square feet.

Destiny designs necklaces.
Alex17521 [72]

Answer:

Step-by-step explanation:

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.

4 : 5 ( = 9 too little )

8 : 10 ( = 18 just right)

12 : 15 ( = 27 too much)

So per necklace, 8 yellow beads and 10 blue beads would be needed. 

I hope this helps :-)

Find x<br>and<br>each of the<br>interior angles.​
Kay [80]

Answer:

Part 1) x=27

Part 2) The measure of the interior angles are 64°-67°-49°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In this problem

(3x-17)^o+(x+40)^o+(2x-5)^o=180^o

Solve for x

Combine like terms

(6x+18)^o=180^o

Subtract 18 both sides

6x=180-18

6x=162

Divide by 6 both sides

x=27

step 2

Find the measure of each interior angle

substitute the value of x in each measure

(3(27)-17)=64^o

(27+40)=67^o

(2(27)-5)=49^o
