How much water is wasted by the leaky faucet in 1 day? 15 drips per 30 seconds

a. 43,200 drips

b. 4 gallons (approximately, actual value is 3.8)

c. 61 cups(approximately, actual value is 60.8, using 3.8 gallons and not 4 gallons)

Step-by-step explanation:

Here, we have a faucet wasting water at a rate of 15 drips per 30 seconds, now we want to calculate the number of drips wasted in a day

To find this, what we need to do is fund the number of seconds in a day first

There are 24 hours with 60 minutes, with each minute having 60 seconds

So the number of seconds in a day = 24 * 60 * 60 = 86,400 seconds

Now 15 drips is wasted in 30 seconds

x will be wasted in 86,400 seconds

x = (15 * 86400)/30 = 43,200 drips are wasted in a day

b. Mathematically , there are about 3,000 drips in a liter of water

So;

3,000 drips = 1 liter

43,200 drips = x liter

x = 43200/3000 = 14.4 liters of water

Mathematically,

1 liter = 0.264 gallons

So 14.4 liters = 14.4 * 0.264 = 3.8 gallon

which is equal to 4 gallons of water approximately

c. Mathematically;

1 gallon = 16 cups of water

So 3.8 gallons of water will measure 3.8 * 16 = 60.8 which is approximately 61 gallons of water

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
