Answer:
In 2050 fish population is 27000
Step-by-step explanation:
Exponential change can be modeled by,
Where 
is the initial value of 750, 
is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and 
is the number of time periods.
The rate of change in percentage is 8.3%
That means, after 1 year fish will become 108.3 for 100 fish.
Then 
Difference of years is, 
Then, 
So, the fish population in 2050 is 27000
Answer:
0.133 ml
Step-by-step explanation:
The two available solutions to be used in the mixture are a 70% solution and a 85% solution
.
x = volume of 70% solution
y = volume of 85% solution
y = 2 ml
Therefore;
0.7 x + 0.85(2) = 0.75(x+2)
0.7x + 1.7 = 0.75x + 1.5
multiply through by 10 to get rid of the decimals
7x + 17 = 7.5x +15
collecting and simplifying
-0.5 x = -0.2
divide both sides by -1.5
x = -0.2/-1.5
x = <u>2/15 ml or 0.1333 ml</u>
