Answer:

A = 50.24 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 4

A = (3.14) 4^2

A =3.14 * 16

A = 50.24 cm^2

Answer:

2)an = 5n + 1

Step-by-step explanation:

This is an arithmetic series.

6 , 11 , 16, 21 ,.....

First term = [tex]a_{1}[/tex] = 6

Common difference = d = second term - first term

                                = 11 - 6 = 5

nth term = [tex]a_{1}+(n-1)*d[/tex]

             = 6 + (n - 1) * 5

            =  6 + n * 5 - 1*5

            = 6 +5n - 5

           = 6 - 5 + 5n

           = 1 + 5n

Answer: 6 2/3

Step-by-step explanation:

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:

= 10/3

= 3 1/3

She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:

= 3 1/3 × 2

= 10/3 × 2

= 20/3

= 6 2/3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Look at 3%2At%2B7=%28+-8+%29.

Moved these terms to the left  %28 +8+ %29

It becomes 3%2At%2B7%2B _green%28+8+%29=0.

Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.

Added fractions or integers together

It becomes 3%2At% 2B % 28+15+%29=0.

Look at highlight_red%28+3%2At%2B15+%29=0.

Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0

It becomes highlight_green%28+0+%29=0.

Result: 0=0

This is an equation! Solutions: t=-5.

Answer: t= -1/3

Step-by-step explanation:

3t+7=-8

subtract 7 from 7 and 8 (this cancels out the 7)

left with 3t = -1

divide 3 into 3t and -1

the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3

Answer:

3^4-1

3^3 = 27

Answer:

-7n is the answer

Step-by-step explanation:

It's easy.

Answer:

a is the answer as it has 2 constant terms in 3 variables

Step-by-step explanation:

constant means a no. (it doesnt changes)

ex. 2 , 7 etc

variable means a term (generally a letter) which changes, its value will differ.

in the equation you have given both have only 2 variables

have you posted all the options?

GOOD LUCK FOR THE FUTURE! :)

Answer: y = -4x + 3

Step-by-step explanation:

y = mx + b

=> y = -4x + b

Find "B":

y = -4x + b

=> 3 = -4(0) + b

=> b = 3

so y = -4x + 3

Given:

A  store manager purchased hoodies for $24.99 apiece.

He sells the hoodies for $32.

To find:

The markup percentage.

Solution:

We have,

Cost price (C.P.) = $24.99

Selling price (S.P.) = $32

We know that,

[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]

[tex]\text{Markup percentage}\approx 28.05[/tex]

Therefore, the markup percentage is 28.05%.

Answer:

17*square root of 5

Step-by-step explanation:

Form a triangle like the one shown  below and use the pythagorean theorem:

[tex]17^2+34^2=c^2\\289+1156=c^2\\1445 = c^2\\c = \sqrt{1445} \\c = 17\sqrt{5}[/tex]

Answer:

Monthly salary= $4,228

Step-by-step explanation:

Giving the following information:

Fixed salary= $2,500

Sales commission= 10%

Sales= $24,600

To calculate the monthly salary, we need to use the following formula:

Monthly salary= fixed income + commission

Commission= (24,600 - 15,000)*0.18

Commission= $1,728

Monthly salary= 2,500 + 1,728

Monthly salary= $4,228

Answer:

  0.666... = 6/9 = 2/3

Step-by-step explanation:

The repeating decimal 0.666... can be turned to a fraction as follows.

Let x represent the value of the number. Then 10x is ...

  10x = 10(0.666...) = 6.666...

Subtracting x gives ...

  10x -x = 6.666... - 0.666... = 6.000...

  9x = 6

Dividing by 9 and simplifying, we have ...

  x = 6/9 = 2/3

__

It can be worthwhile to remember that  1/9 = 0.111... repeating.

Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating

and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating

Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...

  2 ÷ 3 = 0.6666667 or 0.66666666667

or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.

_____

Additional comment

A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

      = 334.65

Answer:

1. Move the variables to one side: 3(-4+4) = -3n

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

which is also equal to

n=0

Answer:

The discount is $120, so the discount price would be $280

Step-by-step explanation:

(30 x 400) / 100  = 120 (Discount Ammount)

400-120=280 (Discount Price)

Answer:

6. c. 120

7. $6.45

Step-by-step explanation:

1. 150 x 0.20 = 30

2. 150- 30= 120

1. 43 x 0.15= 6.45

Step-by-step explanation:

10X+ 180= 500

10X= 500-180

10X= 320. .....divine both sides by 10 to solve for X

X = 32.

check

10(32)+180 = 500

320+180 =500

500 =500...confirmed
