A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 140 lb and each box of books weighs 40 lb . The maximum capacity of elevator is 690lb how many boxes of books can the delivery person bring up at one time?

13 boxes

Step-by-step explanation:

690-140=550

550 divided by 40 is 13.75 because you can’t have .75 of a box you round down to 13

it has the same slope and a different y-intercept

hope this : )

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
