Answer:

Step-by-step explanation:

What are the factors of 40? 8 * 5

8 + 5 = 13

 

To do it algebraically gives you a quadratic:

A + B = 13

AB = 40

 

A(13 - A) = 40

A2 - 13A + 40 = 0

 

(A - 8)(A - 5) = 0

 

A = 8 and B = 5

When a transversal is perpendicular to two parallel lines, all the angles formed measure 90°. Explain why.
kotykmax [81]
When two parallel lines are cut by a transversal, due to the natures of the different relationships among the angles, all of them will be either equal to the measure of the first angle or equal to that angle subtracted from 180.  If the transversal is perpendicular to the parallel lines, forms a right angle, then both the angle given and the angle subtracted from 180 will be 90.  This means all of the angles will be 90.

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.
