Gabby baby sat 2 hours each night for 20 nights. She earned a total of $360 babysitting. Gabby wants to calculate her hourly rate. How much did Gabby earn per hour babysitting?

$9 per hour

Step-by-step explanation:

First, divide her total by 20 to find how much she got per night:

360/20

= 18

Then, divide this by 2 to find her hourly rate, since she worked 2 hours a night:

18/2

= 9

So, Gabby earned $9 per hour babysitting

 $9

Step-by-step explanation:

2 × 20 = 40         [total running time]

360 ÷ 40 = 9       [Gabby earns per hour babysitting]

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
