Estimates show that there are 1.4 * 10^8 pet fish and 9.4 * 10^6 pet reptiles in the United States. How many are there total in the United States? express in scientific notation.

Answers

There are total of 2.34*10^(8) pet fish and reptiles in the United States.

Define the term expression?

Calculations that include changeable altering multipliers, joining, removal, and random subdivision must be done. They could accomplish the following if they united: An algorithm, some data, and a mathematical problem.

To find the total number of pet fish and reptiles in the United States, we simply need to add the number of pet fish and pet reptiles together:

Total = 1.4*10^(8) + 9.4*10^(6)

To add these numbers together, we need to express them using the same power of 10. We can do this by rewriting 9.4 * 10^6 as 0.94 * 10^7:

Total = 1.4*10^(8) + 0.94*10^(7)

Now, we can add the numbers together:

Total = 1.4*10^(8) + 0.94*10^(7)

= 1.4 * 10^8 + 0.94 * 10^8   (since 10^7 = 10 * 10^6 = 10^1 * 10^6 = 10^7)

= 2.34 * 10^8

Therefore, there are a total of 2.34 * 10^8 pet fish and reptiles in the United States.

Therefore , the solution of the given problem of expressions comes out to be the total number of pet fish and reptiles in the US is roughly

1.494 * 10⁸.

What precisely is an expression?

It is necessary to perform calculations which it involve joining, removal, and random subdivision variable changing multipliers. If they banded together, they could do the following: A mathematical challenge, some information, and an algorithm. A statement of equation truth contains formulas, elements, and arithmetic procedures like additions, subtractions, errors, and groupings. It is possible to assess and analyse words and phrases.

Here,

The number of fish and reptiles kept as pets must be added to the overall number of pets:

=> 1.4 * 10⁸ + 9.4 * 10⁶

We must change these numbers to the same power of 10 in order to add them. Since 108 is equal to 100 million,

we can achieve this by moving the decimal point in the second figure two places to the right:

=> 1.4 * 10⁸ + 0.094 * 10⁸

We can now multiply the numbers:

=> 1.494 * 10⁸

Thus, the total number of pet fish and reptiles in the US is roughly

=> 1.494 * 10⁸.
