Step-by-step explanation:
Answer:

Step-by-step explanation:
We are given that
Volume of water in fish pond,V=3000 L
Mass of toxic chemical=5 kg
Rate=200L/min
Removes chemical=50%
We have to find the differential equation for the time.
Let mass of toxic at any time t= m kg
Rate=Rate in-Rate out



The answer would be 50 because in order to find the measure of a supplementary angle,you have to multplify it's radius or diameter by2
