A  dripping  faucet is  wasting 0.5 ml of water every second. how many litersof  water does it waste per week? write your answer with the  correct number of significant digits. 

we are given

A dripping faucet is wasting 0.5 mL of water every second

so, dropping rate is 0.5mL/seconds

we have to find amount of waste in 1 week

so, firstly we will find total time in seconds

1 week = 7 days

1 day =24 hours

1 hours =3600 seconds

now, we can change 1 week into seconds

we get

1 week = 7*24*3600 seconds

so, total time is 7*24*3600 sec

total amount of water wastes =  dropping rate * total time

now, we can plug values

now, we can change into L

1 L =1000 mL

so, we get

so, total water wastes in 1 week is 302.4 L.........Answer

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
