Is the following number rational or irrational?
0.3pi
Choose 1

Irrational

Step-by-step explanation:

Irrational numbers are any real numbers that cannot be expressed as the quotient of two integers, or simply as a fraction.

If we were to multiply 0.3, the estimation is 94 hundredths, or 0.94.

Extended

0.94247

·The answer doesn't represent the quotient of any real numbers.

·The answer can't be written as a simple fraction.

A Rational number is the opposite:

·Rational numbers can be written as a simple fraction.

·Rational numbers represent the quotient of any real numbers.

Since 0.3 is a rational number, and is an irrational number, the answer is irrational.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
