Answer:

  • A: 27,500
  • B: 14,700
  • C: 12,800

Step-by-step explanation:

Section A holds half the seats in the stadium, so 27,500 seats.

Revenue from a sold-out section A will be ...

  $35×$27500 = $962,500

so the combined revenue from B and C seats is ...

  $1,448,500 -962,500 = $486,000

If we let "b" represent the number of section B seats, then the number of section C seats is (27,500 -b) and the revenue from sold-out sections B and C will be ...

  20b +15(27500 -b) = 486000

  5b = 73,500 . . . . . . . . subtract 412,500

  b = 14,700 . . . . . . . . . . divide by 5; number of Section B seats

  27,500-b = 12,800 . . . number of Section C seats

There are 27,500 Section A seats, 14,700 Section B seats, and 12,800 Section C seats.

Answer:

Section A: 27,500 seats.

Section B: 14,700 seats.

Section C: 12,800 seats.

Step-by-step explanation:

We set up a system of 3 equations where a, b and c are the number of seats in Section A B and C,

a = b + c                                   (1)

a + b + c = 55000                   (2)

35a + 20b + 15c = 1448500   (3)

From equation 1;

a - b - c = 0

Now if we add this to equation 2:

2a = 55,000

a = 27,500  So there are 27,500 seats in Section A.

Substitute for a in equation 3:

35* 27,500 + 20b + 15c = 1448500

20b + 15c = 486000       (4)

b + c = 27,500

b = 27,500 - c

Substitute for b in  equation 4:

20*(27500 - c)  + 15c = 486000

-20c + 15c = 486000 - 550000

-5c = -64000

c = 12800

So b = 27500-12800

= 14700

A fish tank is three-fourths full.
max2010maxim [7]

Answer: \frac{5}{12}

Step-by-step explanation:

   We will subtract the amount of water that leaked out from the amount of water originally in the fish tank.

\displaystyle \frac{3}{4} - \frac{1}{3} =\frac{3*3}{4*3} -\frac{1*4}{3*4} =\frac{9}{12} -\frac{4}{12}=\frac{5}{12}

         The fish tank is \frac{5}{12} of the way full.

The graph of this system of equations is used to solve 4x2-3+6=2x4-9x3+2x What represents the solution set?
Vilka [71]

ANSWER

x coordinates of the intersection points

EXPLANATION

The given system of equations is:

y = 4 {x}^{2}  - 3x + 6

y = 2 {x}^{4}  - 9 {x}^{3}  + 2x

We want to use the graph of these functions to solve

4 {x}^{2}  - 3x + 6 =  2 {x}^{4}  - 9 {x}^{3}  + 2x

The point of the intersection of the graph gives the solution to the simultaneous equation above.

Hence the x-coordinates of the intersection points gives the solution set of

4 {x}^{2}  - 3x + 6 =  2 {x}^{4}  - 9 {x}^{3}  + 2x

The last choice is correct.
