How many dollars per hour greater is the hourly rate for Company G than Company H?

3

Step-by-step explanation:

company g is charging 10 per  hour and in the graph when it is zero hours it shows the base charge which is 25 but in addition when you add an hour if you subtract that amount minus the flat amount 25 you will get 7 and will continue to do so as you continue across the graph 10-7 equals 3

i dont know sorry

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
