Answer:

The Correct Answer is option D.

Step-by-step explanation:

Tina observed that the temperature was 72 degrees. Later the temperature rose 21 degrees and then dropped 11 degrees.

 

That is, 72+21-11=82.

 

She then flew to New York where the temperature was 67 degrees.

 

The change in temperature from when Tina left Atlanta and arrived in New York is,

82-67=15.

 

Hence, the change in temperature is 15.

 

Thus, the correct option is D.

Tell which set or sets the number below belongs​ to: natural​ numbers, whole​ numbers, integers, rational​ numbers, irrational​
Alexus [3.1K]

Answer:

<h3>Rational numbers</h3>

Step-by-step explanation:

A rational number is a number that can be written as a ratio of two integers. The are expressed as fractions. Given the value 8/9, this value is a fraction and is written as a ratio of two integers 8 and 9.

The value is neither a real number, nor an integer because integers and whole numbers are not expressed as fractions.

Natural numbers are also whole numbers starting from 1 and above. Hence 8/9 is not a natural number as well.

Note that irrational numbers are also classified as real numbers and they can not be written as a ratio of two integers.

Conclusively, 8/9 is only classified as a rational number
