Artyom0805 [142]

Answer:

100

Step-by-step explanation:

In economics, for a firm to earn optimum profits, it is important that it achieves a long run equilibrium. We can transfer the same to the case here that for the club to achieve optimum attendance, it must achieve long- run equilibrium attendance.

The condition for Long Run Equilibrium is that:

Club meeting attendance this week = Club meeting attendance next week

X = 80 + 0.20X

X - 0.20X = 80

X = 80/0.8

X = 100.

The long- run equilibrium attendance for this club is 100.

I need help on this question I’m confused
AysviL [449]

Answer:

FG = 31

Step-by-step explanation:

By applying mid-segment theorem in the given trapezoid,

Segment joining midpoints of the nonparallel sides is parallel and measure the half of the sum of parallel sides.

FG = \frac{1}{2}[UV+TW]

(7x - 4) = \frac{1}{2}[(6x-6)+38]

2(7x - 4) = 6x + 32

14x - 8 = 6x + 32

14x - 6x = 32 + 8

8x = 40

x = 5

Therefore, FG = (7x - 4)

                        = 7(5) - 4

                        = 31
