The independent variable is whatever object you can control and alter and the dependent variable is the variable which reacts to that one. you didn’t include a description for your experiment but for example, when brushing your teeth the independent variable is the toothpaste and the dependent variable is how much foam stuff will appear when brushing. let me know if that makes sense
Answer:
-8/3 or -2 2/3
Step-by-step explanation:
It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
200 times 9 equals 1800 :)
