A sports stadium has 10000 seats, divided into box seats, lower-deck seats, and upper-devk seats. Box seats sell for 10 dollars,
lesantik [10]

Answer:

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000

Step-by-step explanation:

Let number of box seats = x

Let number of lower deck seats = y

Let number of upper deck seats = z

As per question statement:

x+y+z=10000 ...... (1)

Cost for box seat = $10

Cost for x box seats = 10x

Cost for lower deck seat = $8

Cost for y lower deck seats = 8y

Cost for lower deck seat = $5

Cost for z lower deck seats = 5z

As per question statement:

10x+8y+5z=70000 ..... (2)

z = 4x ..... (3)

Putting value of y in (1) and (2):

x+y+4x=10000\\\Rightarrow 5x+y=10000 ....... (4)

10x+8 y+5\times 4x=70000\\\Rightarrow 30x+8y=70000 ..... (5)

8 \times (4) - (5):

10x =10000

\Rightarrow x = 1000

By (3):

z = 4000

Now, by equation (1):

y = 5000

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000

PLEASE HELP ASAP I NEED THIS DONE ASAP!!!
zubka84 [21]

Answer:

The value of x is 12.

Step-by-step explanation:

Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :

x + 2x + 5 + 6x - 17 + 3x + 2 = 134

12x - 10 = 134

12x = 134 + 10

12x = 144

x = 144 \div 12

x = 12

Which ordered pairs cause this relation NOT to be a function? Why?
dangina [55]

Answer:

(3,1) and (3,2)

Step-by-step explanation:

We are given that a relation

{(0,0.5),(0.5,1),(3,1),(1,6),(3,2)}

We have to find that ordered pair which causes this relation not to be a function.

We know that

Function: It is  a mapping between two non- empty set A and B.

Every element of set A has unique image in set B.

One element of set A can not have two or more images in set B.

Two or more elements of set A have same images in set B.

In given relation images of 3 are 1 and 2 which is not possible if a relation is function because one element can not have two or more images.

The ordered pair (3,2) and (3,1) cause this relation not to be a function because image of 3 are 1 and 2 which is not possible .

Answer: (3,1) and (3,2)
