Yes I have graphed them and they form a 90 degree angle
Answer:
9.08 hours
Step-by-step explanation:
in order to fill 1 pool
fill rate by pipe = 1 pool / 15 hours = 1/15 pool per hour
fill rate by hose = 1 pool / 23 hours = 1/23 pool per hour
combined rate = fill rate by pipe + fill rate by pool
= 1/15 + 1/23 = 38/345 pool per hour
since:
38/345 pool -----------> will take 1 hour
1 pool --------------------> will take 1 hour x (345/38) = 9.08 hours
7 men = 300
? Men = 70
Do you know the next step
Y = 1/3x
This is explained with using rise over run, as the point rises 1 time and moves over 3 times from the y intercept, hence the name. Hope this helps, and makes sense, too!
For this case we have that by definition, the distance between two points is given by:
We have the following points:
Substituting we have:
Thus, the distance between the points is
