Answer:
D
Step-by-step explanation:
Whole numbers are the basic counting numbers: 
Integers are whole numbers and negative numbers: 
Rational numbers are all fractions
where m is an integer and n is a natural number.
Irrational numbers are all real numbers that are not rational.
Number
is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.
The product of integer number -2 by irrational number
is irrational number 
Correct option - option D
The answer will be 17 tons.
Step-by-step explanation:
Since we have given that
14 T 1,000 lb. + 2 T 1,000 lb.
As we know that

So, 14 T 1,000 lb. is given by

Similarly,

so,
2T 1,000 lb. is given by

So, 14 T 1,000 lb. + 2 T 1,000 lbs is given by

Hence, the answer will be 17 tons.
Answer: 9
Step-by-step explanation:
In order to find the people out of the 150, we first multiply 9/25 and 150 together. This will give us the people who DO own a dog. This brings us to 54.
Now, if we multiply 54 by 1/6 we get the answer of 9, because 1/6 of the dog owners own a cat as well. We have now reached the desired amount.
