An 18 foot tall tree casts a shadow of 11 feet. A man casts a shadow of 4 feet assuming these are similar triangles, how tall is the man ?

height of the man is ≈ 6.5

Step-by-step explanation:

shadow of the man/ shadow of the tree = height of the man/ height of the tree

4/11 = x/18                   cross multiply

11x = 4(18)

11x = 72

  x = 6.5

step-by-step explanation:

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
