A bacteria culture doubles twice a day. There are 143,622 bacteria present on day 15. How many were present on day 10?
gtnhenbr [62]

Answer:

140

Step-by-step explanation:

- 143,622 bacteria present on day 15

- the bacteria doubles twice a day

that means each day backwards, the bacteria is four times less the day before

therefore:

- on day 14, the number of bacteria is 143,622 / 4

which is 35,905.5

and so on!

so:

- day 13 = 8,976.375

- day 12 = 2,244.09375

- day 11 =  561.0234375

- day 10 = 140.255859375

this rounded to the nearest whole number is

= 140 bacteria

(you can't have a part of a bacteria!)

hope this helps! :)

kodGreya [7K]
This is the concept of scale factor. The linear scale factor is given by:
(height of sculpture)/(height of clothespin)
=20/(5/12)
=48
Given that a woman is 5ft 7 in, the sculpture of this woman would be:
height of sculpture=(scale factor)*(height of the woman)
height of the woman=5 ft 7 inches=5 7/12 ft=67/12 ft
hence the height of the sculpture will be:
67/12×48
=268 ft

Answer: 268 ft
