We are given the following data:
total discharge = 9.6 trillion gallons
number of household = 200 million
number of months = 6 months
So the average use of each household per month is:
average use = (9.6 trillion gallons) / (200 million households * 6 months)
average use = 8,000 gallons / household / month
So each household uses 8,000 gallons per month

A bucket holds c liters of water, but a jar holds 8 liters less. How many times as much water can the bucket hold as the jar?
The ratio representing how many times as much water the bucket can hold as the jar is [tex]\frac{c}{c-8}[/tex], where c is the capacity of the bucket in liters.
If a bucket holds c liters of water and a jar holds 8 liters less than the bucket, then the jar holds c - 8 liters of water. To find how many times as much water the bucket can hold as the jar, we divide the bucket's capacity by the jar's capacity. This gives us the ratio of the bucket's capacity to the jar's capacity, which is [tex]\frac{c}{c-8}[/tex].
Find an equation of the line that has a y-intercept of -2 and is perpendicular to the graph of 3x+6y=2
Marlene rides her bicycle to her friend Jon's house and returns home by the same route. Marlene rides her bike at constant speeds of 6 mph on level ground, 4 mph when going uphill and 12 mph when going downhill. If her total time riding was 2 hours, how far is it to Jon's house?
x = level ground
y = hills
x/6 +y/4 +y/12 + x/6 = 2 hours
multiply everything by 12 to get rid of the denominators:
equation becomes 2x +3y +y +2x = 24
combine like terms:
4x +4y = 24
divide everything by 4
f +h = 6 miles to Jon's house
Jon's house is 6 miles further away from Marlene's house.
Given that:
Speed on level ground is 6 mph
Speed on uphills is 4 mph
Speed on downhills is 12 mph
Let there are x miles level ground and y miles hills(either up or low, which while returning to home will serve as low or up respectively) in the route, then the whole route's length is x + y miles.
Since time taken = distance/speed , thus we have:
[tex]2 = \dfrac{x}{6} + \dfrac{y}{4} + \dfrac{x}{6} + \dfrac{y}{12}\\\\\text{Multiplying 12 on both sides}\\\\24 = 4x + 4y\\6 = x + y[/tex]
Since x + y denotes the length of the whole route(one sided), thus, Jon's house is 6 miles further away from Marlene's house.

You have 120 pieces of fabric to make a blanket. Each piece of fabric is the square with a side length of 6 inches. You use as many pieces of fabric is possible to create a square blanket. What is the area of the blanket
Answer:
Step-by-step explanation:
Hello! So, you use 120 pieces of fabric. You could not use all 120 pieces, because you can not make a square. The most you could use to make a square is 100. That would be 10 squares a row, with a side length of 6, which would make a perimeter of 60. Then, the other side would be 60. So 60 * 60 is 3600. The area of the blanket is 3600 square inches.
Two buses are traveling to a state park. One bus leaves the terminal at 4:00 p.m. and travels at 40 miles per hour. The second bus leaves the terminal at 5:00 p.m. and travels at 60 miles per hour. How much time passes until the second bus catches up with the first bus?Assessment timer and count Assessment items Two buses are traveling to a state park. One bus leaves the terminal at 4:00 p.m. and travels at 40 miles per hour. The second bus leaves the terminal at 5:00 p.m. and travels at 60 miles per hour. How much time passes until the second bus catches up with the first bus?
Answer:
Time passes until the second bus catches up with the first bus = 2 hours
Step-by-step explanation:
One bus leaves the terminal at 4:00 p.m. and travels at 40 miles per hour.
Speed of Bus 1 = 40 miles per hour
Time of leaving of Bus 1 = 4:00 p.m
The second bus leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
Speed of Bus 2= 60 miles per hour
Time of leaving of Bus 2 = 5:00 p.m
We need to find when they catch up
That is the distance traveled by them are same,
Let the time of travel for bus 1 be t, so time of travel for bus 2 is t -1
We have
Distance = time x Speed
Distance traveled buy bus 1 = Distance traveled buy bus 2
40 x t = 60 x (t -1 )
40 t = 60 t - 60
20t = 60
t = 3 hours,
So after 3 hours of starting of bus 1 they catch up,
Time passes until the second bus catches up with the first bus = t- 1 = 2 hours
Time passes until the second bus catches up with the first bus = 2 hours
The second bus takes 2 hours to catch up with the first bus after closing a gap of 40 miles at a relative speed of 20 miles per hour.
Calculating the Time for the Second Bus to Catch Up
To determine how much time passes until the second bus catches up with the first bus, we need to calculate the distance that the first bus travels before the second starts and then use the relative speeds of the buses to find out when the second bus will have covered the same distance.
The first bus travels for one hour before the second starts, covering a distance of:
Distance = speed x time = 40 miles/hour x 1 hour = 40 miles.
When the second bus starts, it closes the gap at a relative speed, which is the difference in their speeds:
Relative speed = 60 miles/hour - 40 miles/hour = 20 miles/hour.
To find out how long the second bus takes to catch up, we use the formula:
Time = Distance / Relative speed = 40 miles / 20 miles/hour = 2 hours.
So, it will take the second bus 2 hours to catch up with the first bus.
