Asubmarine begin the day to 240 m below sea level. it descended 40 m/h for three hours and then ascended 30 m/hrs. for five hours what was the position of the submarine after the 8 hour time period . measured in meters

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

i think the answer is 90 hope this
