"Order of operations" - the order in which you must simplify an equation 
"Origin" - center of the coordinate plane at (0,0)
"Outlier" - A number in a set of numbers that is way different than the rest (example: 1, 2, 3, 4, 5, 27. 27 is the outlier)
"octagon" - an 8 sided polygon

Answer:

8) Real; Rational

9) Real; Rational; Integer; Whole; Natural

10) Real; Rational

Step-by-step explanation:

Real numbers consists of the subsets:

Irrational Numbers:

Irrational numbers is the subset complementary to rational numbers. It includes numbers such as √(2) or π. These numbers do not repeat nor terminate.

Rational Numbers:

Rational numbers are all the others. They include the integers as well as the repeating and terminating decimals.

Integers:

Integers include the entire set of whole numbers and the negative numbers. This subset does not include decimals nor fractions. Thus, the integers are: ...-3, -2, -1, 0, 1, 2, 3... etc.

Whole Numbers:

Whole numbers is the set of natural numbers that <em>includes</em> 0. So, whole numbers are: 0, 1, 2, 3... and so on.

Natural Numbers:

Natural numbers or the counting numbers are all the positive, non-decimal numbers. These are 1, 2, 3... and so on. This set does not include 0.

8) 1.\overline{3}=1.3333...

The given number is not natural, whole, nor an integer because it is a decimal. It repeats, so it belongs to the rational numbers subset.

9) \sqrt4=2

The square root of 4 is simply 2. 2 is a natural number. Because of this, this means that 2 is also a whole number, integer, and a rational number.

10)-3/4=-0.75

The given number is a fraction and it does not reduce to a whole number, so it's not a natural number, whole number, nor an integer. It does terminate, so it belongs to the rational numbers subset.

Mr. Wallace needs to divide his class or 23 students into 9 groups. Each group can have two or three students. If a is the numbe
IRINA_888 [86]

Answer:

d)  Mr.Wallace can use the following equations:

    a + b = 9

   2 a + 3 b = 23

Step-by-step explanation:

Here, the total number of students = 23

Number of groups = 9

Each group can have 2 or 3 students.

a is the number of  groups of 2.

⇒ Total students in a groups  = a x (Number of  student in each group)

= a x 2 = 2 a

b is the number of groups of 3

⇒ Total students in b groups  = b x (Number of  student in each group)

= b x 3 = 3 b

So, according to the question:

Total number of groups formed = 9

⇒ a + b = 9

Total number of students  = 23

or Number of students in  ( a  group + b group ) = 23

⇒ 2 a + 3 b = 23

Hence, Mr.Wallace can use the following equations:

a + b = 9

2 a + 3 b = 23

Which number is one hundred thousand times larger than 5.6 x 102 ? A) 5.6 x 106 B) 5.6 x 107 C) 5.6 x 108 D) 5.6 x 109
Vladimir [108]
Hello! I believe you are referencing to powers of 10. In this case 10^2 is 100. 5.6 * 100 = 560. Okay. We are looking for the expression that will give the solution that is 100,000 times greater than 560. Okay. 100,000 * 560 is 56,000,000. That is 56 million. In this case, 10^7 is equivalent to 10,000,000, because there are 7 zeros behind the 1. 5.6 * 10^7 is 56,000,000. There. 56 million is 100,000x greater than 560. The answer is B.
