0.000005607 converted to Scientific Notation would have a positive exponent. True or False? Explain why
False. This is a small number, less than 1. Also, the decimal is already visible(in the front) and needs to be moved backwards. This type of number has a negative exponent.

-4.5 belongs in which categories?
Rational and Real
300
What is wrong with this statement:
Whole Numbers are a subset of Integers which are a subset of Rational. So all three Categories share each other's numbers.
All three Categories do NOT share each other's numbers. Integers do not contain rational numbers and Whole numbers do not contain integers/rational numbers.

Imperfect Squares are: Rational or Irrational
Irrational

11%, 1/9, 0.12, and 1/8

Which option is written incorrectly in Scientific Notation and WHY?
A - 5.6 x 105
B - 7 x 10-11
C - 0.99 x 103
D - 1.004 x 10-8
Option C because the number before the "x10" is less than 1.

Order the lakes in descending order:
Richland Chambers, Conroe, Travis, Possum Kingdom and Amistad
400
Which number is larger and WHY?
5.4 x 1032 or 9.3 x 10-43
5.4 x 1032 because the exponent is positive and much larger than 9.3 x 10-43 which is much much smaller than 1.
500
Name all of the categories that 178 belongs to.
Counting/Natural, Whole, Integer, Rational, Real
500
Which is the correct answer and WHY?
D - Every decimal number is an irrational number
Decimals are rational is they terminate and are predictable.

What is the difference in perfect and imperfect squares?
Perfect Squares have an answer that is whole "4". They're also rational.
Imperfect Squares have an answer that is a decimal.
They're also irrational.
