Question

A dripping faucet loses about 2.5×10−42.5×10−4 liters of water each minute. There are approximately 3×1053×105 minutes in a month. About how many liters of water are lost because of the dripping faucet in a month?

Answer 1

75 liters of water is lost because of the dripping faucet in a month.

Explanation:

Given : A dripping faucet losses
`2.5 * 10^(-4)` liters of water each minute.

Also , a month has approximately
`3 * 10^5` minutes.

Total liters of water lost because of the dripping faucet in a month = water loss each minute × minutes in a month

`=2.5 *10^(-4)*3 *10^5`

Using property of exponents,
`a^xa^y=a^(x+y)`,

`=2.5 *3 *10^((5-4))`

`=7.5 *10^(1)`

`=75`

Thus, 75 liters of water is lost because of the dripping faucet in a month.
