Answer:
2 times the square root of 41
1 gallon= 16 cups
1=16 2=16 3=16 4=16
16*4=64
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
Let
x -----> the amount of weight
y ----- the amount a spring will stretch
we know that
For x=80 lb, y=2.1 in
<em>Find the value of k (constant of proportionality)</em>

substitute the values

The linear equation is

How far will it stretch when 40 pounds is attached?
For x=40 lb
substitute the value of x in the linear equation and solve for y

Answer:
I think its 0.03 but I'm not a 100 percent sure
Your answer is 13.44 and rounded to the whole is still going to be 13
