Cells ina certain plant can triple in number every 15 minutes.How many times greater is the number of plant cells after an hour and a half then the number of cells the plant had origanally?
It triples every 15 mins. So that's 3x's greator. There are 4, 15 min intervals in an hr so 3 x 3 x 3 x 3=81 times greator than when you started
an hour and a half has 6 periods of 15 minutes, not 4
so the multiplication factor is
3x3x3x3x3x3 = 3^6 = 729
Thanks.Reiny you were correct.

To find out how many times greater the number of plant cells is after an hour and a half compared to the original number, we need to determine how many times the cells triple in that timeframe.
First, let's calculate how many 15-minute intervals there are in an hour and a half. Since each interval is 15 minutes, dividing 90 minutes (an hour and a half) by 15 gives us 6 intervals.
Now, since each cell triples in number every 15 minutes, we can calculate the growth factor for each interval. Since it triples, the growth factor is 3.
So, to find the total growth factor after 6 intervals (1 hour and a half), we raise 3 to the power of 6 (3^6) since each interval is independent of the others.
Calculating 3^6, we find that the total growth factor is 729 (3^6 = 729).
Therefore, the number of plant cells after an hour and a half will be 729 times greater than the original number of cells.
