a stadium has 55,000 seats. seats sell for $35 in section a, $20 in section b, and $15 in section c. the number of seats in section a equals the total number of seats in sections b and c. suppose the stadium takes in $1,448,500 from each sold-out event. how many seats does each section hold?

section a holds seats.
section b holds seats.
section c holds seats.

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.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

its kind of blurry. can you put a clearer pic?
