Amanda is adding the numbers below.3.7 x 10^(20) + 4.45 x 10^(20)

What is the sum written in scientific notation?

Answers

Answer 1
Answer: Basically what you do is                             (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = 815000000000000000000

An animal shelter has 7 puppies. If the puppies are 28% of the total dog and cat population, how many dogs and cats are in the animal shelter?

Answers

79 is the answer I believe.

Final answer:

The total number of dogs and cats in the animal shelter is 25. We get this by dividing the number of puppies, which represent 28% of the population, by 0.28.

Explanation:

To figure out the total dog and cat population in the animal shelter, we need to use the information given to us: the puppies, which make up 28% of the total population, number 7. To get the full population, we need to think of these 7 puppies as representing 28%. The way to get the total is to divide the number of puppies by the percentage they represent. Express 28% as a decimal and divide:

7 / 0.28 = 25

So there are 25 dogs and cats in the animal shelter.
