We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:
4.27 - 4 = 0.27
Now we can set up a proportion to find the percentage.

Solve for x
0.27 x 100 = 27
27/4 = 6.75
The answer is
6.75% :)

This is a trapezoid cause has 2 lines paralel and 2 lines are not paralel.
Answer:

The graph is attached below.
Step-by-step explanation:
Given the system of inequalities.

Isolate y for 

subtract x from both sides

simplify

Multiply both sides by -1 (reverse the inequality)

simplify

now solving

isolate y for 

subtract x from both sides

simplify

Divide both sides by 2

Simplify

Graphing Method:
1. Graph each inequality separately
2. Choose a test point to determine which side of the line needs to be shaded
3. The solution to the system will be the area where the shadings from each inequality overlap one another.
Thus,

The graph is attached below.
