To find the perimeter, we must add together the length of each side.

The tick mark on the lines means they are equal, so that means we have two lines that are equal to 10

26 + 10 + 35 + 5 + 10 + (38 - 10) = 114"

Answer:

Gianna makes $18 per hour.

Step-by-step explanation:

Given Gianna makes 90$ for 5 hours. That means she should make $ \frac{90}{5} $ $  = 18$ every hour.

Therefore we have:

a.

HOURS                    DOLLARS

  1                                   18

  2                                  36

  3                                  54

  4                                   72

  5                                   90

  6                                   108

  7                                   126

b.

For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.

c.

If Gianna works for 8 hours she would have made 8 X 18 = 144$.

So, she will earn 144$ in 8 hours.

d.

To make 60$ she would have to work $ \frac{60}{18} $ hours = 3.33 hours.
