Answer:
A. the dependent variable
Step-by-step explanation:
The given equation is
[tex]f = 5280m[/tex]
This equation is used to convert a distance between miles and feet,where f represents the number of feet and m represents the number of miles.
The value of f depends on the value of m.
This means that, to find f, we need to first know m.
Therefore f is called the dependent variable.
