Hey there,
2 hours = 15 pages
1 hour = 15 / 2
           = 7.5 pages
15 pages = $40
1 page = $40 / 15
            = $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
               = $20

Hope this helps :))

A researcher measures daily driving distance from college and weekly cost of gas for a group of commuting college students. What
juin [17]

Answer:

There is a positive correlation between these two variables.

Step-by-step explanation:

Positive correlation is an association amid two variables in which both variables change in the same direction.  

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

As the distance covered by the vehicle increases the amount of gas consumed also increases. Thus, the weekly cost of gas will also increase.

Thus, there is a positive correlation between these two variables.

Two trains leave towns 474 kilometers apart at the same time and travel toward each other. One train travels13 km/m faster than
guajiro [1.7K]

Answer:

112 km/h

125 km/hr

Step-by-step explanation:

Distance = time * speed

Distance  = distance train 1 + distance train 2

474 = 2(s) + 2(s + 13)

Distribute

474 = 2s + 2s + 26

Combine like terms

474 = 4s + 26

Subtract 26 from both sides

448 = 4s

Divide both sides by 4

112 = s

s = 112 km/h

s + 13 = 125 km/hr

kiruha [24]
Joseph was swimming faster because 1/12 of a mile per minute is around 5 miles per hour so Joseph was swimming 0.5 miles per hour faster than Joe.
