Answer:
Dependent Variable- l Independent Variable-b
Step-by-step explanation:
Dependent Variables are always Y and Independent Variables are always x.
In this case y=I and x=b. The amount of water your water bottle will hold will never change. But the amount of water you drink can change.
If we let
be the number of pages read in 1 hour, then in 7 hours Doug reads
pages. We know that this number of pages is 231, so we have

The value of x in that equation is -12
I'm going to assume that the ' 7.51 ' is the angle expressed in radians.
So this is just like any other unit conversion exercise.
You know that 180 degrees = pi radians.
Divide each side by pi radians, and you have
180 degrees / pi radians = 1 .
Great ! Now take the angle you have ... 7.51 radians ...
and multiply it by ' 1 '.
(7.51 radians) x (180 degrees / pi radians) =
<em> </em> (7.51 x 180 / pi) degrees =<em> 430.29 degrees</em>
As you ( I ) worked through this problem, a very useful number
fell out . . . It's 180/pi = 57.296 , or just <em>57.3</em> is close enough.
Here's how you can use that number:
-- 1 radian = <u>57.3</u> degrees
-- 1 degree = 1/57.3 of a radian
-- Got some radians ? Multiply by <u>57.3</u> to get degrees.
-- Got some degrees ? Divide by <u>57.3</u> to get radians.
