Which number produces an irrational number when added to 0.4

An irrational number is any number that cannot be expressed as a fraction of two integers. So, any number that is not rational would produce an irrational number when added to 0.4. Some examples of irrational numbers are π (pi), √2 (square root of 2), or e (Euler's number).

Which number produces an irrational number when added to 0.4

√9

3 π

0.444...

2/7

The number that produces an irrational number when added to 0.4 is √9.

√9 is equal to 3, which is a rational number. Adding a rational number to 0.4 would still result in a rational number. Therefore, √9 does not produce an irrational number when added to 0.4.

Which of the following statements is true if p is an integer and q is a nonzero integer?

A rational number can be written as a fraction

all numbers can be written as a fraction

an irrational number can be written as a fraction

a rational number cannot be written as a fraction

The correct statement is: A rational number can be written as a fraction.

Which number produces an irrational number when multiplied by 1/3

0.166

-√17

2/3

2

The number that produces an irrational number when multiplied by 1/3 is -√17.

√17 is an irrational number since it cannot be expressed as a fraction. When multiplied by the rational number 1/3, the result is still irrational. Therefore, -√17 produces an irrational number when multiplied by 1/3.

True or False:

The number 0.3333... repeats forever; therefore, it is irrational.

False. The number 0.3333... is a repeating decimal, but it is still rational. It can be expressed as the fraction 1/3, which means it is a quotient of two integers.
