440 yards x 20 = 8800 yards.
8800 yards is equal to 5 miles.
Answer:
Step-by-step explanation:
In going from (5, 5) to (10, 8), x (the run) increases by 5 and y (the rise) increases by 3. Thus, the slope of the line connecting the first two points is m = 3/5.
In going from (1, 13) to (4, 8), x (the run) increases by 3 and y (the rise) decreases by 5. Thus, the slope of the line connecting the first two points is m = -5/3
Because these results are negative reciprocals of one another, the two lines are PERPENDICULAR to one another.
First you need to set this problem up as a cross multiply fraction set (actually forgot the name of it so I described it as that).
10/15 * 30/x
Solve for X
450 = 10x
Simplify
45 = x
The Daily dose is 30 meq/45 ml. For a 30 day supply you just multiply by 30.
1350 ml is needed for a 30 day supply.
