Which number produces an irrational number when added to 0.4

erastovalidia [21]

Answer:

0.31311311131111....

Step-by-step explanation:

We need to tell a number which when adds to 0.4 makes it a Irrational Number . We know that ,

Rational number :- The number in the form of p/q where p and q are integers and q is not equal to zero is called a Rational number .

Irrational number :- Non terminating and non repeating decimals are called irrational number .

Recall the property that :-

Property :- Sum of a Rational Number and a Irrational number is Irrational .

So basically here we can add any Irrational number to 0.4 to make it Irrational . One Irrational number is ,

$\rm\implies Irrational\ Number = 0.31311311131111...$

So when we add this to 0.4 , the result will be Irrational . That is ,

$\rm\implies 0.4 + 0.31311311131111 ... = 0.731311311131111 ..$

The area of a rectangle is 42 square inches. the length is 7 inches.what is the perimeter of the rectangle?

andrew11 [14]

In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.

If f(x) is a linear function, which statement must be true?

Harlamova29_29 [7]

The statements look all false:

A linear function can have constant terms, which is the b coefficient in the expression y=mx+b. For example, y=3x+5 has a constant term 5
A linear function has a x term. In the same example as before, 3x is the x term
The coefficients can be different from 1. In the example before, the x coefficient is 3 and the constant term is 5.
This looks like option b. Maybe there was a typo, and either b or d must be true.
