Which of the following is a rational number?

Morgarella [4.7K]

Answer:

Square root of 100.

Step-by-step explanation:

Step-by-step explanation:

We can write 10 as a fraction 10/1, therefore, $\sqrt{}$ 100 is a rational number.

Part A : A rational no. between 5.2 and 5.5 is 5.3.

It is rational because it can be expressed in the form

p/q where p and q are integers and q is not equal to 0, which is 53/10

Part B: A rational no. between 5.2 and 5.5 is 5.29150262213

An irrational number between 5.2 and 5.5 is 5.29150262213. It is irrational because there is no pattern that repeats and it cant be written as a fraction of two whole numbers.

Suppose that a local trout population exhibits exponential growth by doubling every 4 years. Considering that the initial popula

antoniya [11.8K]

Okay, so this is just a basic multiplication problem. first, we need to divide to figure out how much the trout population grows after 1 year. If it doubles in 4 years, then it will rise by a quarter each single year. So to put that in terms of fractions, then for every year, the equation would be 250x1/4. So then we do the equation, coming up with 62.5. This means that the population rises roughly 63 fish a year. So after 1 year, you will have roughly 313 fish. (312.5 to be exact). Then to get that by ten years, we can just multiply the number that we got for one year by ten. 62.5x10=625. So then we add the 250 original trout, and 250+625=875. So after 10 years, there will be 875 trout.
