Thickness of 1 quarter = 1.75 mm
So, 1000 quarters will be = 
= 1750 mm
So, a stack of 1000 quarters will be 1750 mm high.
We can employ some logic to reduce the answers we need to test. We know that the slope perpendicular to line l has to have a negative reciprocal slope, so a slope of
. We see that in A and C, as x increases so does y. That means the slope of these equations are positive, which we don't want. Now for some algebra:

We se that D has the correct slope so that must be the answer.
Answer:
3 : 10
Step-by-step explanation:
most simplified form
This should be the right answer.
