Answer: Everybody will need to pay 3.18 dollars. ($3.18)

Step-by-step explanation:

To find out equal amounts of money, you need to divide the total cost by how many people there are. The total cost, in this case, is 12.72, and the amount of people in this problem is 4 people. That means, if everybody were to pay the same amount, you would need to divide 12.72 by 4.

12.72/4=3.18

A water trough is 9 m long and has a cross-section in the shape of an isosceles trapezoid that is 20 cm wide at the bottom, 70 c
ella [17]

Answer:

dv = surface area * dh

so

dv/dt = surface area * dh/dt

width at surface = 40 + (80-40)(30/40)

= 40 + 30 = 70 cm = 0.70 m

so

surface area = 9 * .7 = 6.3 m^2

so

.3 m^3/min = 6.3 m^2 * dh/dt

and

dh/dt = .047 meters/min or 4.7 cm/min
