can someone help me with this algebra problem?

Question

An airplane covered 13 miles of its route while decreasing its altitude by 18,000 feet. Find the slope of the airplane's line of descent. Round to the nearest hundredth. [Hint: 1 mi = 5280 feet.]

Answer 1

rise = -18000 feet (negative since it is going down)
run = 13 miles = 13 x 5280 feet = 68640 feet

slope = rise / run
= -18000 / 68640
= -0.262237762

Round to the nearest 1/100
= -0.26

Answer 2

slope= rise/run

you have to first convert your 13 miles into feet:

13 times 5280 = 68640 feet.

You do this so that your terms on your graph will be the same:
ex: 18,000 feet
and 68,640 feet

Then, your airplane is going down, not up...so make 18,000 negative: -18,000

y= rise/ up and down: -18,000

x=run/ left to right: 68,640

slope= -18,000/68,640

slope= -.26 feet

Answer 3

the hint gives it away...

13 miles converted to feet is..._________
then you have two numbers, both in feet.
the slope is "rise" over "run", which means the altitude divided by the distance travelled...round to the nearest hundredth.

I won't give you the answer, but I think I have provided enough hints...

Answer 4

Slope is rise over run or y/x

So this would be 3.41/13

decimal version rounded is 0.26

since plane is going down it would be -0.26..indicating you decend (Y axis) 0.26 miles for every mile traveled along the route (sideways or X axis)

Answer 5

Girl with a Pearl Earring. I watched it the other night, and it will take your mind off things. Believe me, you need to look at Scarlett Johanssen.

Answer 6

13/(-18000/5280)
=13/(-3.409091)
=-3.81
