If a faucet drips 2ml of water every second, how much water will it spill waste in 2 days?
Svet_ta [14]

Answer:

\boxed{345,600 mL}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well first we need to find the amount of seconds in a day,

24hrs in a day * 60 min in an hour

= 1440 minutes in a day

1440 min • 60 secs in a minute

= 86,400 seconds in a day

So now we do 2*86400 = 172800

172800 mL in a day

172800 * 2

= 345600 mL in 2 days

<em>Hope this helps :)</em>

At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperatures is 50° Celsius. Thi
Simora [160]

Answer:: D(t)= 50(4/5)^t

Step-by-step explanation: If 1/5 of the temperature difference is lost each minute, that means 4/5 of the difference remains each minute. So each minute, the temperature difference is multiplied by a factor of 4/5 (or 0.8).

If we start with the initial temperature difference, 50° Celsius, and keep multiplying by 4/5, this function gives us the temperature difference t minutes after the cake was put in the cooler.
