**Answer:**

[tex]8^{18}[/tex]

**Step-by-step explanation:**

Using the rule of exponents

[tex]a^{m}[/tex] ÷ [tex]a^{n}[/tex] = [tex]a^{(m-n)}[/tex] , then

[tex]8^{15}[/tex] ÷ [tex]8^{-3}[/tex]

= [tex]8^{(15-(-3))}[/tex]

= [tex]8^{(15+3)}[/tex]

= [tex]8^{18}[/tex]

The **simplified **form is 8^18

The **exponent **of a **number **shows how **many** times the **number **is **multiplied** by **itself**. For example, 2×2×2×2 can be written as 24, as 2 is multiplied by itself 4 times. Here, 2 is called the "base" and 4 is called the "exponent" or "power." In general, xn means that x is multiplied by itself for n times.

The **properties **of **exponents **or laws of exponents are used to solve problems involving exponents. These properties are also considered as major exponents rules to be followed while solving exponents. The properties of exponents are mentioned below.

**Given**:

8^15÷8^−3

Using

a^m / a^n = a^( m-n)

So,

8^15÷8^−3

=8^(15-(−3))

=8^(15 +3)

=8^18

Three bands and two comics are performing for a student talent show. How many different programs (in terms of order) can be arranged

The **different programs **(in terms of order) that can be **arranged** is** 120 different ways**

Since we are dealing with** arrangements,** this is a **permutation** problem.

If there are three bands and two comics performing at a show, the total band will be 5 bands

Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages in the book?

StartFraction 25 times 6 Over 100 times 6 EndFraction = StartFraction 150 Over 600 EndFraction

StartFraction 100 times 4 Over 25 times 4 EndFraction = StartFraction 400 Over 100 EndFraction

StartFraction 25 divided by 1 Over 150 divided by 1 EndFraction = StartFraction 25 Over 150 EndFraction

StartFraction 150 divided by 2 Over 100 divided by 2 EndFraction = StartFraction 75 Over 50 EndFraction

**Answer:**

x = 600 pages

Step-by-step explanation:

Let the total books pages be x

Given that

Hank had read = 25% of x

25% of x = 150

=>

Multiplying both sides by 4

=> x = 150 * 4

=> x = 600 pages

4) Eric bought a canoe for $333.75. He bought a life vest for $134.87 and an ore paddle for $67.89

The sales tax was 5.25%. What was his total cost?

**Answer:**

His total cost is $564.68

**Step-by-step explanation:**

333.75 + 134.87 + 67.89 = 536.51

536.51 x 0.0525 = 28.17

536.51 + 28.17 = 564.68

A machine takes 15 minutes to scan 1,125 pages. At this rate, how many pages can the machine in a hour?

**Answer:**

4500 pages

**Step-by-step explanation:**

an hour has 60 minutes. This means in 1 hour the machine will scan 60/15 more pages. 60/15 =4.

1125*4 =4500 pages/hour

In one hour the machine will scan **4500 pages**.

Given is that a machine takes 15 minutes to scan 1,125 pages.

The machine takes 15 minutes to scan 1,125 pages.

Then, in 1 minute, it will scan (1125/15) = 75 pages.

So, in 1 hour, it will scan -

x = 75 x 60

x = 4500

Therefore, in one hour the machine will scan **4500 pages**.

If A=2x+10 and B=2x+2 what is the measurement of A

**Answer:**

Answer:

28+66+86=180

180=180

Step-by-step explanation:

Since there is a triangle and the 3 measures from the angles we can find the value of x using the hint given that the sum of the interior angles must be 180°

Write the equation

\begin{gathered}x+(2x+10)+(3x+2)=180\\\end{gathered}

x+(2x+10)+(3x+2)=180

Simplify left side of the equation

\begin{gathered}6x+12=180\\\end{gathered}

6x+12=180

Solve equation for x

\begin{gathered}6x=180-12\\6x=168\\x=28\end{gathered}

6x=180−12

6x=168

x=28

Replace x into the 3 angles and find their respectives values

\begin{gathered}A=x\\A=28\\\\B=2x+10\\B=2*28+10\\B=56+10\\B=66\\\\C=3x+2\\C=84+2\\C=86\end{gathered}

A=x

A=28

B=2x+10

B=2∗28+10

B=56+10

B=66

C=3x+2

C=84+2

C=86

The graph of a proportional relationship passes through the given point and (1, y). Find y.

Given point: (19, 342)

**Answer: 4/3**

**Step-by-step explanation:**

Allen is showing his work in simplifying −8.3 + 9.2 − 4.4 + 3.7. Identify any errors in his work or in his reasoning.

Step Work Reasoning

−8.3 + 9.2 − 4.4 + 3.7 Original problem

1 −8.3 + 9.2 + 4.4 + 3.7 Additive inverse

2 −8.3 + 4.4 + 9.2 + 3.7 Commutative property

3 −8.3 + (4.4 + 9.2 + 3.7) Associative property

4 −8.3 + 17.3 Simplify

5 9 Simplify

He did not make any errors.

Step 1: He wrote −4.4 incorrectly as + 4.4.

Step 2: He identified changing the order of the numbers as the commutative property, which is incorrect.

Step 3: He identified changing the grouping of the numbers as the associative property, which is incorrect.

**Step-by-step explanation: First, you use the PEMDAS method which is parenthese, exponent, multiplication division, addition and subtraction. **

**So, there is parenthese, exponent, multiplaction or division. **

**Now, first you add -8.3 + 9.2= 0.9, then subtract 0.9 by 4.4= -3.5, now add -3.5 + 3.7= 0.2**

**Use the original problem and use the PEMDAS method. **

What is the solution to the equation?

Enter your answer in the box.

x =

x= -14.5

**Step-by-step explanation:**

-1.3=x-(-13.2)

the two - signs cross eachother out, making it a +.

making the equation -1.3=x-(-13.2) turn into -1.3=x+13.2.

so you should automatically know your x is going to have to be negative.

**What I did:**

13.2+1.3=14.5,

but since the 1.3 was actually negative, (-1.3) the 14.5 will turn negative, making it -14.5

(1,4) after a translation left 5 units and down 5 units?

Answer: (-4, -1)

When solving this equation I took the point given (1,4) and subtracted five units from one and five units from four. The reason being because they are asking you what the translation would be if 1 were to be moved 5 units the left causing it to be negative and moving 4, 5 units down causing it also to be negative because of its direction being moved.

How many floors have exactly 24 offices?

=============================================================

Explanation:

Focus on the first row only. This involves the stem 2 and various leaves. The stem 2 refers to having a tens digit of 2. So it involves the numbers 20 through 29.

More narrowly, we're involving the values: 20, 22, **24, 24**, 27, 29. Each value corresponds to exactly one leaf in that first row. For example, a stem of 2 and a leaf of 7 combine to form the number 27. Often, there will be a key at the bottom of the stem-and-leaf plot to indicate this in shorthand (eg: 2|7 means 27).

In that first row, we see the value 24 shows up **twice**. This means that there are **2 floors** where there are 24 offices on those floors.

Yes, because the amount owed changes by 2. 25 every time the miles change by 1. No, because the amount owed does not change by 1 every time the miles change by 2. 25. No, because the amount owed does not change by 2. 25 every time the miles change by 1.

**Linear functions **are represented by **constant rates**.

The true statement is (d) No, because the **amount owed **does not **change **by 2.25 every **time **the **miles **change by 1.

From the table, we can see that:

As the number of **miles **increase by 1, the **amount owed **increases, but it does not increase at a **constant rate **of 2.25.

A pet store holds training classes for dogs. The store has two different training programs. The first program charges a $35 membership fee and $5 for each class. The second program does not have a membership fee, but charges $10 for each class. For how many classes will the programs cost the same? If the variable c represents the number of classes, what is the other variable for the scenario? d, representing the number of dogs in each class h, representing the number of hours p, representing the number of programs t, representing the total cost.

**Answer:**

7?

**Step-by-step explanation:**

The **programs **cost the same for** 7 classes**.

Given, no. of **classes **is represented by **c**, no. of **dogs **is represented by **d**, no. of **hours **is represented by **h**, the no. of **programs **is represented by **p **and the total **cost **is represented by **t**.

The **first program **charges **$35 membership fee **and** $5** for each class.

The **second program **charges only **$10** for each class.

Now the total cost say [tex]t_{1}[/tex], for first program can be written in equation form as,

[tex]t_{1} =35+5c[/tex], here c is the no. of classes.

Similarly, the **total **cost say [tex]t_{2}[/tex] , for second program can be written in **equation **form as,

[tex]t_{2} =10c[/tex].

We **have **to find out the **no**. of **classes **for which the **two programs **cost the **same**.

according to the question,

[tex]t_{1} =t_{2}[/tex]

[tex]35+5c=10c\\10c-5c=35\\5c=35\\c=7[/tex]

Hence for **7 **of **classes **the **programs **cost the **same**.
