561/4

Step-by-step explanation:

Given that:

Height of first hill (f) = 255 feets

Height of second hill (s) = 11/20 the height of first hill

Height of second hill (s) = 11/20 of 255

Calculate the height of second hill:

s = 11/20 * 255

(11 * 255) / 20

= 2805 / 20

= 561 / 4

Height of second hill = 561/4

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
