Answer:
13.6 cm
Step-by-step explanation:
The slope of -0.6 tells you the change in height in 7 hours will be ...
(-0.6 cm/h) · (7 h) = -4.2 cm
This is added to the candle height after 12 hours, so the height after 19 hours is ...
17.8 cm -4.2 cm = 13.6 cm

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! :)
last one because you can solve it to many way6s
