Zoe is working two summer jobs, making $7 per hour babysitting and making $15 per hour clearing tables. In a given week, she can work a maximum of 14 total hours and must earn at least $130. If Zoe worked 4 hours babysitting, determine all possible values for the number of whole hours clearing tables that she must work to meet her requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.

She must work at least 7 hours. All possible values are 7, 8, 9, 10

Step-by-step explanation:

14 - 4 = 10

4($7)=$28

$130-$28=$102

$102÷$15=6.8

$15x7=$105

$105+$28=$133

$15x8=$120

$120+$28=$148

$15x9=$135

$135+$28=$163

$15x10=$150

$150+$28=$178

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
