The independent variable is
The dependent variable is
the number of

independent is r and dependent is y

Step-by-step explanation:

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.

a tree grows a ring for each year, therefore, to determine a trees age, you need to count the rings. the rings "r" dictate the age or years "y"

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

1 is c

2 is a

3 is a
