Answer 1

Answer:  (a) sometimes, (b) true, (c) 6 ft

Step-by-step explanation:

You need to understand the difference between Whole, Integers, Rationals, and Irrationals in order to answer the question.

Whole numbers are Natural numbers plus 0:

0, 1, 2, 3, 4, ...      notice that these are all positive numbers

Integers are Whole numbers plus their opposites:

... -3, -2, -1, 0, 1, 2, 3, ...          notice that positive numbers are included

Rationals are integers but also include fractions whose decimal equivalent either repeats or terminates:

$... -2, ..., -1\dfrac{1}{2}, ..., -1\dfrac{1}{3}, ... -1, ..., 0, ..., 1, ..., 1\dfrac{1}{3}, ..., 1\dfrac{1}{2}, ..., 2, ...$ notice that positive numbers are included

Irrationals are numbers whose decimal equivalent does not repeat or terminate:

$..., -\sqrt3, -\sqrt2, ..., \sqrt2, \sqrt3, ...$     notice that positive numbers are included

a) If a number is positive, then it is a Whole, Integer, and Rational.

Sometimes because it could also be an Irrational.

b) If a number is a perfect square, then it is a Whole, Integer, and Rational.

True because an irrational number cannot be a perfect square.

c) What is the length of a square whose Area is 36 ft².

Area = side squared   -->   A = s²   -->   36 ft² = s²    -->  6 ft = s
