Find the area of the shaded region, steps are appreciated! Thanks!

360÷20 = 18sides

U divide 360 by 20 because angles at the center add up to 360°

The given polygon will have 18 sides in total.

Given information:

The diagram shows part of a regular polygon.

The sides of this polygon subtend angles of 20° at the center of the polygon.

Let the polygon has n number of sides.

Now, the polygon is regular. So, its each side will be equal and it will make equal angle with the center.

The sum of angles made by all the sides will be equal to 360 degrees.

So, the number of sides n can be calculated as,

[tex]20\times n=360\\n=\dfrac{360}{20}\\n=18[/tex]

Therefore, the given polygon will have 18 sides in total.

Solution,

Given data=12,13,19,16,32,15,13

Highest score=32

lowest score=12

a. Range= highest score- lowest score

= 32-12

= 20

B. Arranging the data in ascending order

[tex](y-k)=a(x-h)^2,\ a\neq0[/tex]

[tex](a\pm b)^2=a^2\pm2ab+b^2\qquad(*)[/tex]

We have

[tex]y=-4x^2-8x-7[/tex]

distribute

[tex]y=-4(\underbrace{x^2+2x+1}_{(*)})-3[/tex]  

use (*)

[tex]y=-4(x+1)^2-3[/tex]

add 3 to both sides

Answer:

x = 7.

Step-by-step explanation:

-18 = 6 (x - 10)

-18 = 6x - 60

6x = -18 + 60

6x = 42

x = 42/6 = 7.

Answer:

[tex]x=7[/tex]

Step-by-step explanation:

[tex]-18=6(x-10)[/tex]

Use distributive property.

[tex]-18=6x-60[/tex]

Add 60 on both sides.

[tex]-18+60=6x[/tex]

[tex]42=6x[/tex]

Divide by 6 on both sides.

[tex]\frac{42}{6} =x[/tex]

[tex]7=x[/tex]

Another method.

[tex]-18=6(x-10)[/tex]

Divide by 6 on both sides.

[tex]-18/6=x-10[/tex]

[tex]-3=x-10[/tex]

Add 10 on both sides.

[tex]-3+10=x[/tex]

[tex]7=x[/tex]

Answer:

s = 1.17, -23.17

Step-by-step explanation:

s^2 + 22s = 27

Take the coefficient of s

22

Divide by 2

22/2 =11

Square it

11^2 =121

Add this to both sides

s^2 + 22s+121 = 27+121

s^2 + 22s+121  = 148

(s+11)^2 = 148

Take the square root of each side

sqrt((s+11)^2) = ±sqrt(148)

s+11 =  ±sqrt(148)

Subtract 11 from each side

s+11-11 = -11  ±sqrt(148)

s =  -11  ±sqrt(148)

s = -11 + sqrt(148) = 1.1655

   - 11 - sqrt(148)=-23.166

Rounding to the nearest hundredth

s = 1.17, -23.17

Answer:

13/6

Step-by-step explanation:

6/13 * x = 1

Multiply each side by 13/6

6/13 * 1/3 6  * x = 1 * 13/6

x = 13/6

The instructions state "there are a  minimum of 16 players and at most 20  players on the team". This means that we have between 16 and 20 players, inclusive of both endpoints. Therefore, x can take on any whole number between 16 and 20. The domain is the set of allowed x inputs of a function.

Look up how  to find volume and you'll get the answer right away

Step-by-step explanation:

Answer:

10 units

Step-by-step explanation:

Let us find the volume of Haley's prism and compare it with the volume of Jeremiah's.

The volume of Haley's prism is:

V = 5 * 3 * 4 = 60 cubic units

Jeremiah's prism has twice the volume of Haley's:

V(J) = 2 * 60 = 120 cubic units

This implies that:

120 = 4 * 3 * h

where h = height of prism

=> 120 = 12h

=> h = 120 / 12 = 10 units

Jeremiah's prism is 10 units tall.

Answer:

(a+b)(a+b-c)

Step-by-step explanation:

Formula:

(a+b)² = a² + b² + 2ab

Therefore,

a²+b²+2ab -ac-bc

= (a+b)² -ac-bc

Now take -c common in ac and bc

(a+b)² -c(a+b)

now take (a+b) common in both terms

(a+b)(a+b-c)

.

The value of the equation is A = ( a + b ) ( a + b - c )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = a² + 2ab + b² - ac - bc   be equation (1)

On simplifying the equation , we get

( a + b )² = a² + 2ab + b²

So ,

A = ( a + b )² - ac - bc

Taking the common factor in the equation , we get

A = ( a + b )² - c ( a + b )

Taking the common factor in the equation , we get

A = ( a + b ) ( a + b - c )

Hence , the equation is A = ( a + b ) ( a + b - c )

20+10=6x-3x

30=3x

x=10

Answer:

Step-by-step explanation:

Three times a number increased by ten equal to twenty less than six times a number. Let the number be [tex]x[/tex].

[tex]3x + 10 = 6x-20[/tex]

Add [tex]-6x[/tex] and [tex]-10[/tex] on both sides.

Step-by-step explanation:

in math we can write as this

[tex] \frac{4}{x + 7} = \frac{3}{x + 4} [/tex]

4(x+4)= 3(x+7)

4x + 16 = 3x + 21

4x - 3x = 21 - 16

x = 5

Answer:

x=5

Step-by-step explanation:

You can approach this question in many different ways, but i'm gonna look at it algebraically, since it's the quickest and works pretty much all the time.

First, you want to convert the words they've given you and make it into a less confusing equation.

They told us that 4 divided by (x+7) = 3 divided by (x+4), which is the same as:

[tex]\frac{4}{x+7}[/tex] = [tex]\frac{3}{x+4}[/tex]

Now, we can multiply both sides by (x+7), which gives me:

4 = [tex]\frac{3(x+7)}{x+4}[/tex]

Now we can multiply both sides by (x+4), to get rid of the fractions:

4(x+4) = 3(x+7)

Then expand the brackets:

4x + 16 = 3x + 21

Move the x to one side and numbers to another side:

4x - 3x = 21 - 16

x = 5
