Answer:
The dependent variable is A
The independent variable is w
Step-by-step explanation:
Given

Required
Identify the variables
In 
The value of w is independent of the value of A.
In other words:
A derive its own value from w; by multiplying 25 and w.
Take for instance:

The value of A would be:


Hence:
The dependent variable is A
The independent variable is w
Cross multiply
19(x) = 30(9.5)
Simplify
19x = 285
Divide 19 from both sides
19x/19 = 285/19
x = 285/19
x = 15
B. 15 is your answer

Answer:
22 Feet
Step-by-step explanation:
All the lengths of a square are the same length.
The area of a square is the length times the width. The length and the width are the same measurement. So, we are looking for the square root of 479.

21.88606863 is as far as my calculator goes. This is an irrational number. That means that it never repeats or terminates as a decimal. They tell us to answer to the nearest foot. That would be 22 feet.
The answer is 6.5
