<span>If you didn't know the precise measurements, you could lay the stick on the rug and measure how many of those yardsticks fit onto that rug. Then you could take that yardstick to a store and find a new one by applying the same type of measuring and you would find things that are the same size. You would use the stick for reference.</span>

maksim [4K]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

If you have completed $5$ questions, you still have $25-5=20$ more questions to answer. We need to find what fraction $20$ is of $25$ , if that makes sense. A fraction is simply a part over a whole. In this case, the part is $20$ and the whole is $25$ . Therefore, the fraction we are looking for is $\frac{20}{25}$ , which simplifies to $\frac{4}{5}$ . Hope this helps!

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.
