Independent variable (IV): something the scientist can change.
Thus, in this case, the IV can be the weight of the person.
Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
Jordan spends 50 minutes on his homework.
Step-by-step explanation:
Given,
Time spent on Maths homework = 11 minutes
This represents the 22% time of his total homework.

For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches
