Which number produces an irrational number when added to 0.4

1 answer:

VARVARA [1.3K]3 years ago

7 0

I don't think when this number is added to any other rational number would produce an irrational number

But we do know that when 0.4 is added to an irrational number it would be irrational.
e.g; 0.4 + pi is irrational, etc, etc
So any other irrational number would make it irrational

Another stack of books is 43 inches tall. Each book is 1/2 inch thick. Write an expression that represents the number of books i

enyata [817]

Answer:

86 books

Step-by-step explanation:

A stack of books is 43 inches tall.

Each book is $\frac{1}{2}$ inch thick.

To find the number of books in tha stack, divide the height of the stack by the height of the book:

$43:\dfrac{1}{2}$

The division by the fraction $\frac{1}{2}$ is equivalent to the multiplication by the fraction $\frac{2}{1},$ so

$43:\dfrac{1}{2}=43\cdot \dfrac{2}{1}=43\cdot 2=86$
