8/12 and 9/12 shows them written both with a common denominator. When you find common denominators, you have to do the same to the numerator and denominator. The other answers have not done this. So we know it will not be the first choice because 3/4 cannot become a greater number by multiplying both the numerator and denominator by the same number. We know it won't be the second option because 3 isn't a factor of 8. It won't be the third option either because 3 is not a multiple of 2. So we are left with the last one.

You have 2/3 and 3/4
You need to find common denominator
You need to multiply both bottoms to get the same number on the bottom
Shorter story you need to multiply the bottom numbers by a number to get the same number on the bottom
When you get that make sure you multiply both tops by the same number
2/3 3/4

3x4= 12. 4x3=12.
Your denominator is 12
Now multiply the numerator by the same number you multiplied the denominator by.
2x4=8. 3x3=9

A population of fish in a lake is 14000 in 2010. The population decreases 6% annually. What is the population in 2019
kodGreya [7K]

Answer:

8022.

Step-by-step explanation:

Let x be the number of years after 2010.

We have been given a population of fish in a lake is 14000 in 2010. The population decreases 6% annually.

We can see that population of fish is the lake is decreasing exponentially as it is decreasing 6% annually.

Since we know that an exponential function is in form: y=a*b^x, where,

a = Initial value,

b = For decrease or decay b is in form (1-r) where r represents decay rate in decimal form.

Let us convert our given decay rate in decimal form.

6\5=\frac{6}{100}=0.06

Upon substituting our given values in exponential form of function we will get the population of fish in the lake after x years as:

y=14,000*(1-0.06)^x

y=14,000*(0.94)^x

Let us find x by subtracting 2010 from 2019.

x=2019-2010=9

Upon substituting x=9 in our function we will get,

y=14,000*(0.94)^9

y=14,000*0.5729948022286167

y=8021.927\approx 8022

Therefore, the population of fish in 2019 will be 8022.
