Wasted Water A faucet leaks 1 oz of water per minute. a) How many gallons of water are wasted in a year? (A gallon contains 128

dimaraw [331]

Answer:

a) 4106.25 gallons

b) $46

Step-by-step explanation:

We are given the following in the question:

Leakage rate of faucet = 1 oz per minute

Cost of water = $11.20 per 1000 gallons

1 gallon = 128 oz

a) water are wasted in a year

1 hour = 60 minutes

1 day = 24 hours

1 year = 365 days

$1\text{ year} = 365\times 24\times 60\text{ minutes}\\1\text{ year} = 525600\text{ minutes}$

Amount of water wasted =

$\text{Leakage rate}\times \text{Time}\\=1 \times 525600\\=525600\text{ oz}\\\\=\dfrac{525600}{128}\\\\=4106.25\text{ gallons}$

Thus, 4106.25 gallons of water is wasted every year.

b) additional money spent

$=\time{Cost}\times \text{Amount of water wasted}\\\\= \dfrac{11.20}{1000}\times 4106.25\\\\=45.99\$ \approx 46\$$

Thus, approximately $46 is the additional money spent on water bill.

Hey can someone help me with #8? I need to find the rate of change and idk where to get started

AveGali [126]

I’m not 100% sure I’m correct on this but when she started at 12,584 miles, her tank was full. After driving, it was at 12,584 miles which is a difference of 208 miles. So if you put that into a fraction: it would be 31.12 dollars/208 miles, Which means every 31.12 dollars spent, she is able to drive 208 miles. Now all you need to do is simplify that. If you divide 31.12 by 208, you get around .149. That rounded would be about .15 gallons of gas. So every (and I don’t know if t tells you to round or not so be careful on that) .149 dollars, (not 149, it’s .149) she goes one mile.
