A scientist is growing bacteria. The number of bacterial cells triples every week.

There are currently 20 cells.

Which expression shows how to find the number of cells in 4 weeks?

o f(4) = 3 20^4
o f (4) = 4 - 20^3
o f(4) = 20 - 3^4
o f (4) = 20 - 4^3​

what are the answear choices to the question.

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

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
