MA_775_DIABLO [31]

Answer:

Explanation:

The whole numbers are the numbers that we use to count like 1, 2, 3, ...

Then, integer numbers are the set that contains the whole numbers and the negative numbers, so the integer number are like ... -3, -2, -1, 0, 1, 2, 3, ...

Therefore, -648 is an integer number.

Finally, the rational numbers are numbers that can be written as a/b, where a and b are integers.

So, the answer is A because rational numbers contain integer numbers, integer numbers contain whole numbers and -648 is a integer number.

There is a math joke that floats around the internet every once in a while that goes something like . . . A mathematician and he

salantis [7]

Answer:

Three beers.

Step-by-step explanation:

The first mathematician orders 1 beer, the second orders 1/2 a beer, the third orders 1/4 a beer, the fourth orders 1/8 a beer, the fifth orders 1/16 a beer. . .

The Sequence is: $1,\frac{1}{2}, \frac{1}{4}, \frac{1}{8}, \frac{1}{16} \cdots$

On observation, the next term is derived through the division of the previous term by 2.
2 is the constant factor
Therefore, the bartender says 'Fine, I’ll just pour you two beers.'

Therefore, if the first mathematician orders 6 beers, the second orders 2 beer, the third orders 2/3 a beer, and so on

The sequence is $6,2,\frac{2}{3}, \cdots$

On observation, the next term is derived through the division of the previous term by 3.
3 is the constant factor
Therefore, the bartender should pour three beers.
