Answer:

The answer is 650

Step-by-step explanation:

You need to find the slope.

i took the points (2, 100) and (4, 200)

Then i put it into the slope formula which is y2 - y1/ x2- x1

I got that the slope is 50. So every two hours 5o millmeters for water drops. So now at 12 hours on the graph it says 600 millimeters of wate has already dropped. The graph is at intervals of two. Now at the next point it will be 14. So just add 50 to 600 and you get 650. So at 14 hours 650 water should have dripped

If your car gets 28 miles per gallon and you travel 30 miles round-trip to work five days a week, how much do you pay each 4-wee
disa [49]

Answer:

You'd pay $65.35 every 4 weeks

Step-by-step explanation:

First you have to gather all the miles.

30 miles x 5 = 150

So that is 150 miles/per week

Then you have to devide the miles by how many gallons per gas you travle.

150/28 miles per gallon = 5.3571....

That how many gallons you'll need a week.

Now, you times the gallons by the price of the gas

5.3571... x $3.05 = $16.3392...

Finally you times the amoutn of money for a week time 4 weeks.

$16.3392... x 4 = $65.35 (to the two decimal mark)

Hope this helped you! : )
