2y^3 m is the width of the rectangle
Step-by-step explanation:
Area of the rectangle = 60y^4 sq. m
Length of the rectangle= 30y m
Area = length x width
60y^4 = 30y x width
Width = 60y^4/ 30y
= 2y^3
The width of the rectangle is 2y^3 meters
2 units

Answer:
51.877 kg
Step-by-step explanation:
a
See attachment for calculations
b
The amount of salt in the tank after 4 hours is gotten by simply replacing t in the equation from a, with 4 hours. Since the t gotten in a above is in minutes, we'd convert hours to minute as well. If we do that, we have
t = 4 hours = 4 * 60 minutes = 240 minutes
y = 160/3 (1 - e^((-3 * 240)/200))
y = 160/3 (1 - e^(-720/200))
y = 160/3 (1 - 0.0273)
y = 160/3 (0.9727)
y = 51.877 kg
Therefore, the amount of salt in the tank after 4 hours is 51.877 kg
