57% people ordered steak. 120 did not. how many customers were there that night?

1 answer:

4 0

X - number of customers

$120+57\%x=x\\
120+0.57x=x\\
0.43x=120\\
x\approx297.07$

There can't be a fraction of the number of people, so there must be some mistake in the question.

Answer:

Înălțimea bazinului este de 20 m

Step-by-step explanation:

Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m

Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²

300 m² = lungime × 15 m

lungime = 300 m² / 15m

lungime = 20 m

Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m

Prin urmare, înălțimea bazinului = 20 m.

2x + y = -8<br> 3x - 5y = -25

Margarita [4]

Answer:

x=-5, y=2. (-5, 2).

Step-by-step explanation:

2x+y=-8

3x-5y=-25

------------------

5(2x+y)=5(-8)

3x-5y=-25

-------------------

10x+5y=-40

3x-5y=-25

--------------------

13x=-65

x=-65/13

x=-5

2(-5)+y=-8

-10+y=-8

y=-8-(-10)=-8+10=2

-3(-5)-3y=-6 find the value of y

julia-pushkina [17]

-3 (-5) - 3y = -6

15 - 3y = -6

-3y = -6 + (-15)

-3y = -21

y = -21 / -3

y = 7

The value of y is 7.
