Astadium has 49,000 seats. seats sell dor $25 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 $1,052,000 from each sold-out event. how many seats are in each section?

Section A has 24,500 seats.

Section B has 14,400 seats.

Section C has 10,100 seats.

Step-by-step explanation:

Let the number of seats in Section B be y and in Section C be z  seats.

Number of seats in Section A is 1/2 * 49000 = 24,500.

Also   y + z = 24,500 (1)

And using the costs of the tickets:

25*24,500 + 20y + 15z = 1,052,000

20y + 15z = 1052000 - 25*24500

20y + 15z =  439,500 (2) Now multiply (1) by 20:

20y  + 20z = 490,000             Subtracting

-5z = - 50,500

z = 10,100

and y = 24500 - 10,100

= 14,400.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

i belive those are the ones that are under 90 degreese.
