A 72,000 gallon water tower is being drained. Two thousand gallons are drained in the first hour. How many hours will it take to
1 answer:
Answer:
To drain the water tower it will take 36 hours.
Step-by-step explanation:
Given:
A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.
Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.
Gallons of total water in the tower ÷ Gallons of water drained per hour
Therefore, to drain the water tower it will take 36 hours.

Answer:
coordinate of point A is (a,b)
coordinate of point C is (2c,d)
slope of AD and BC =
Step-by-step explanation:
According to midpoint formula
If we have points P and Q
then the coordinate (x,y) of mid point of line PQ is given by
and
now from the given diagram A is the mid point of line joining R(0,0) and S(2a,2b)
Using midpoint formula, coordinates of point A is given by
and
so we have
coordinate of point A is (a,b)
Also C is the midpoint of line joining T (2c,2d) and V(2c,0)
coordinate of point C is given by
and
so we have
coordinate of point C is (2c,d)
it is given that coordinate of point B is (a+c, b+d) and coordinate of D is (c,0)
If we have points P and Q
then the slope of PQ =
hence slope of AD=
=
=
=
and slope of BC =
=
=
=
so we have
slope of AD and BC =
