Answer:
Step-by-step explanation:
The Westside recreation center built a new swimming pool that measures 20 ft by 15 ft. The pool is rectangular. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
Therefore, perimeter of the pool would be
2(20 + 15) = 70 ft
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore, area of the pool would be
20 × 15 = 300 ft^2
The formula for determining the volume of a rectangle is expressed as
Volume = length × width × height
Given depth = 6 feet
Therefore, volume of the pool would be
20 × 15 × 6 = 1800 ft^3

Price of movie ticket in Japan is x=7.362$
Price of movie ticket in Switzerland is y=13.652$
Step-by-step explanation:
Let, Price of movie ticket in Japan is x
Price of movie ticket in Switzerland is y
Statement 1 : Total of 79.39$ of three movie ticket in Japan and two movie ticket in Switzerland
We write, 3x+2y=79.39 ( Equation 1 )
Statement 1 : Total of 75.68$ of two movie ticket in Japan and three movie ticket in Switzerland
We write, 2x+3y=75.68 ( Equation 2 )
Solving by method of elimination
Multiplying equation 1 by 2, we get
6x+4y=158.78
Multiplying equation 2 by 3, we get
6x+9y=227.04
Subtracting both the linear equation,
6x+4y=158.78
- 6x+9y=227.04
_______________
0x-5y=(158.78-227.04)
-5y=(-68.26)
5y=68.26
y=13.652$
Replacing value of y in any equation
3x+2y=79.39
3x+2(13.652 )=79.39
x=17.362$
Thus,
Price of movie ticket in Japan is x=7.362$
Price of movie ticket in Switzerland is y=13.652$
Answer:
n= -6
Step-by-step explanation:
Make an equation
We know that the number multiplied by 3 must equal -18
3*n=-18
Divide both sides by 3
n=-6

Answer:
25/2
Step-by-step explanation:
Caio comprou uma lembrança para todos os amigos e gastou R $ 12,50.
Comparando e resolvendo as opções dadas a nós,
