Answer:
trump
Step-by-step explanation:
There are total of pet fish and reptiles in the United States.
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 =
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 =
Now, we can add the numbers together:
Total =
= (since )
=
Therefore, there are a total of 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.
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.

The correct answer is:
Option: A , Option: B , Option: C , Option: D
For a set to be closed under multiplication means if two elements are taken from that set then their multiplication must also belong to the same set.
A)
The product of a perfect cube and a perfect cube.
Let a be a perfect cube of "m"
and b be a perfect cube of "n"
i.e.
Hence,
i.e.
Hence, this set if closed under multiplication.
B)
The product of 0 and 0.
when we take the product of 0 and 0 then the resultant is also zero.
Hence, this set is also closed under multiplication.
C)
The product of a whole number and a whole number.
When we multiply a whole number to a whole number then the product is again a whole number.
This set is also closed under multiplication.
D)
The product of a perfect square and a perfect square.
Let us take two elements of the set as x and y
i.e.
and
Hence,
i.e.
Hence, the set is closed under multiplication.
