Answer:
B. Geometric sequence.
Step-by-step explanation:
We have been given that Wanahton purified a portion of water with 900 grams of contaminants. Each hour, a third of the contaminants was filtered out.
The amount of contaminants remaining after each hour would be 2/3 of the previous hour amount as 1/3 of contaminants was filtered.
Since amount is not constant, therefore, the sequence would be geometric.
We know that explicit formula for geometric sequence is in form , where,
a = First term,
r = Common ratio.
For our given scenario and
, so our required formula would be:
Therefore, an explicit formula for the given geometric sequence would be .
We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.
In order to find out the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.
Now we can find out out our desirable ratio by substituting our finding in the ratio.
Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.
