Answer:
2 bears in 2020.
Step-by-step explanation:
We have been given that a new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.
We will use exponential decay formula to solve our given problem as:
, where,
y = Final quantity,
a = Initial value,
r = Decay rate in decimal form,
x = Time
Upon substituting our given values in above formula, we will get:
, where x corresponds to year 2000.
To find the population in 2020, we will substitute in our equation as:
Therefore, 2 bears are there predicted to be in 2020.
Since population is decreasing so population is best described as exponential decay.
Answer:
The quantity of flour need by Colby's recipe is cups.
Step-by-step explanation:
Given: Colby adds cups of flour to his mixing bowl and then realizes he put too much.He takes
cup of flour back out of the bowl.
We have to find the quantity of flour need by Colby's recipe.
The quantity of flour need by Colby's recipe = Number of flour cups Colby added - number of flour cups Colby taken out.
that is,
Number of flour cups Colby added =
Number of flour cups Colby taken out =
The quantity of flour need by Colby's recipe =
taking LCM, we get, LCM(3,4) =12
The quantity of flour need by Colby's recipe =
The quantity of flour need by Colby's recipe =
Thus, The quantity of flour need by Colby's recipe is cups.
