Water is a valuable resource that can easily be wasted. In this task you will
Investigate how much water the average American uses each day. You will then
Investigate how much water a family of 4 could save using different strategies,
According to some estimates, the average American uses 80-100 gallons of water
daily. Of this total, the average American uses about:
• 27% by flushing toilets
• 25% while taking showers/baths
• 10% by running the faucet while brushing teeth, washing hands, and shaving
Water is also used for various other purposes (cooking, drinking water, watering
plants, washing clothes, etc.) that account for the remaining percentage of water
used by the average American.
Table 1 shows the average amount of water used during some activities,
Table 1. Water Used by Activity and Duration

*There is no standard definition of the volume of a faucet drip, but the USGS
Water Science School uses militer (ML) as the volume of a faucet drip. So, by
these drip estimates:
• One gallon = 15,140 drips
• One liter = 4,000 drips
1)What percentage of the average American's daily water usage is
described as "various other purposes"?

Christopher wants to join a basketball team but each member has to pay a $300 yearly membership fee. The organization will allow Christopher to pay $15 monthly until he pays off his membership. However, he must pay a $150 deposit down first. Christopher puts the $150 deposit down and will begin paying the $15 fee monthly on April 1st. write a linear equation that will help us find out how many months it will take for Christopher to pay off his entire membership.

Answers

Answer:

10 months

Step-by-step explanation:

this is the equation to determine the number of months it will take to pay the full membership fee

300 = 15x + 150

solve for x

subtract 150 from both sides

150 = 15x

divide both sides by 15

10 = x

it will yake 10 months to pay off the membership

Heya!

So the key is at the top. What I mean by the Key is a=1 b=2 c=3 d=4 e=5 and f=0. You use those numbers and plug them into the associated letters in the problems below. For example, question one with the numbers in it would be, (I might be wrong on this, I apologize)

[tex] \frac{0 + 3^{2} - 2 }{0 - 3} [/tex]

You would then solve the equation, and whatever answer you get for that equation would go with the corresponding numbers and letters on the left.

So for example, if your answer to the first one for example is 7, you would type A. You would then do the same for question 2, 3, and 4, which should reveal the four letter code for you to continue :))
