Alex leaves home, travels 5 miles east, and arrives at the library. He leaves the library and travels 3 miles north to a friend's house. This trip can be plotted on the coordinate plane, where home is the point (0,0). Alex wants to find out how far his house is from his friend's house and uses the distance formula. Which other formula can he use?

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
