F is inversely proportional to √ g . When f = 8 , g = 81 Work out g when f = 4

Step-by-step explanation:

The question is basically saying that f is equal to

when f=8, g=81. Therefore 8=.

Then the next step is to simplify the equation, so k = 72.

The next step is to plug k=72 back into the original equation.

f=

Then you do the last step which is to plug f=4 into the equation which will result in 4=72/sqrt(g) => 4*sqrt (g) =72. Therefore sqrt (g) = 72/4 = 18. Then you square both sides and you get g=324.

care to share were the trapezoid shown is ?

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
