Answer 1

Answer:

There are 2 correct answers. See below.

Step-by-step explanation:

The center of a regular polygon is the center of an inscribed and a circumscribed circle.

Answer 2

The center of a regular polygon is the center of the circumscribed circle, which touches all the vertices of the polygon equally.

The center of a regular polygon is considered the center of the circumscribed circle. This is the circle that touches all the vertices (corners) of the polygon. When dealing with a regular polygon, which has all sides and angles equal, the center of this polygon is also the center of the circle that encloses it. This special circle is known as the circumscribed circle or circumcircle. The center is equidistant to all vertices of the polygon. The centroid of a polygon, which is the geometric center where all the corner points balance evenly, is analogous to the center of the circumscribed circle in regular polygons.

Brenna wrote a business plan for an entrepreneurship class, and now she has to make bound copies. Brenna could use a printer who charges a setup fee of $52 and $5 for every copy printed. Another possibility is to go to the office supply store, where she could pay an up-front fee of $24 and $12 per copy. There is a certain number of copies that makes the two options equivalent in terms of cost. How many copies is that? How much would the copies cost?


For ___ copies, the cost is $ ___ .

Answers

Answer:

for four copies the cost is $72

Step-by-step explanation:

52 + 5a = 24 + 12a

28 + 5a = 12a

28 = 7a

a = 4

52 + 20 = 72

for four copies the cost is $72

20. Carmen can buy bottles of paint for $2.00 each and boxes of colored pencils for $3.50 each. She can spend no more than $42 on art supplies.
a. Write an inequality that shows how many bottles of paint, x, and boxes of colored pencils, y, Carmen can buy.
b. Name three different solutions to the inequality.

Answers

For this case we have to:

x: It is the variable that represents the quantity of paint bottles

y: It is the variable that represents the number of boxes of colored pencils

So, we have:

[tex]2x + 3.50y[/tex]

If you can not spend more than $ 42 then we have:

[tex]2x + 3.50y\leq42[/tex]

Then you can buy 10 boxes of colored pencils and 3 of paint bottles at a cost of $ 41

[tex]2 (3) +3.50 (10)\\6 + 35 = 41[/tex]

You can buy 5 boxes of colored pencils and 12 of paint bottles at a cost of $

[tex]2 (12) +3.50 (5)\\24 + 17.5 = 41.5[/tex]

You can buy 7 boxes of colored pencils and 8 of paint bottles at a cost of $

[tex]2 (8) +3.50 (7)\\16 + 24.5 = 40.5[/tex]

Abigail and her mom are back-to-school shopping at new Navy . Select items are on sale at 43% off their regular price . What is the sale price of an item that has a regular price of $22?​

Answers

Answer:

$12.54

Step-by-step explanation:

To find the solution to a system of linear equations, Verdita begins by creating equations for the two sets of data points
below

Which equations could Verdita use to represent the data sets?
Data Set A: Y-4x-2
Data Set B: y = x+4
Data Set A -4x-2
Data Set B: y = x-4
Data Set A y = 4x+2

Answers

Answer:

y= 4x -2

y= x + 4

Step-by-step explanation:

To find equation for Data set A  and B , pick any two points from the table

(-1,-6)  and (1,2)

To find equation use y=mx+b

where m is the slope and b is the y intercept

[tex]m= \frac{y_2-y_1}{x_2-x_1} = \frac{2+6}{1+1} = 4[/tex]

Use point slope formula, use (1,2)

y-y1=m(x-x1)

y - 2= 4(x-1)

y-2= 4x-4 (add 2 on both sides)

y= 4x -2

(-2,2) and (0,4)

To find equation use y=mx+b

where m is the slope and b is the y intercept

[tex]m= \frac{y_2-y_1}{x_2-x_1} = \frac{4-2}{0+2} = 1[/tex]

Use point slope formula, use (0,4)

y-y1=m(x-x1)

y - 4= 1(x-0)

y - 4=x (add 4 on both sides)

y= x + 4

How the hell is the answer 6 or -4

One of the answers I get is -6 which is not the right one. Where the heck does that -4 come from

Answers

Answer:

The values of y is -4 and 6

Step-by-step explanation:

Solve by factoring y^2 -2y=24

We need to factorize the term y^2 -2y=24.

Rearranging:

y^2 - 2y -24 =0

For factorizing we need to break the middle term such that their sum is equal to -2y and product is equal to -24y^2

We know, -6y*+4y = 24y^2 and -6y + 4y = -2y

y^2 -6y +4y -24 =0

y(y-6) +4(y-6) = 0

(y+4)(y-6)=0

Now, y+4 =0 and y-6 =0

Finding value of y,

y = -4 and y =6

So, the values of y is -4 and 6

find the solution of this system of equations 3x+7y=46 and -3x-8x=-50

Answers

Answer:

x = 6 and y =4

Step-by-step explanation:

It is given that,system of equations 3x+7y=46 and -3x-8x=-50

To find the solution

Let  3x + 7y = 46 --------(1)

-3x-8x=-50   -------(2)

eq(1) + eq(2)

3x + 7y = 46

-3x - 8x = -50

        -y = -4

y = 4

(1) ⇒  3x + 7y = 46

3x + 7*4 = 46

3x= 46 - 28

3x = 18

x = 18/3 =6

Therefore x = 6 and y = 4

What is the value of x , given that the two prisms are similar ?

Answers

Answer:

x = 40 units.

Step-by-step explanation:

Corresponding sides of the 2 prisms are in the same ratio , so:

x / 20 =  10 / 5

x/ 20 = 2

x = 2 * 20

x = 40 units.

ANSWER

The correct choice is A.

EXPLANATION

If the the two prisms are similar, then their corresponding sides are in the same proportion;

This implies that

[tex] \frac{x}{20} = \frac{6}{3} [/tex]

We simplify to get;

[tex] \frac{x}{20}=2[/tex]

We now multiply both sides by 20 yo obtain;

[tex] \frac{x}{20} \times 20 = 2 \times 20[/tex]

We simplify and multiply out to get:

[tex]x = 40[/tex]

Therefore the value of x is 40 units

A dozen chocolate cookies cost $___ and a dozen oatmeal cookies cost $___

Answers

Answer:

A dozen chocolate cookies cost $6

and a dozen oatmeal cookies cost $7

Step-by-step explanation:

Let's assume that cost of 1 dozen chocolate cookies = x

Let's assume that cost of 1 dozen oatmeal cookies = y

then we get equations:

9x+8y=110...(i),

and 9x+5y=89...(ii)

Solve equation (i) for x

9x+8y=110

9x=110-8y

[tex]x=\frac{110-8y}{9}[/tex]...(iii)

plug (iii) into (ii)

9x+5y=89

[tex]9\left(\frac{110-8y}{9}\right)+5y=89[/tex]

[tex]110-8y+5y=89[/tex]

[tex]9\left(\frac{110-8y}{9}\right)+5y=89[/tex]

[tex]110-3y=89[/tex]

[tex]-3y=89-110[/tex]

[tex]-3y=-21[/tex]

[tex]y=7[/tex]

plug y=7 into (iii)

[tex]x=\frac{110-8y}{9}=\frac{110-8(7)}{9}=6[/tex]

So the final answer is given by:

A dozen chocolate cookies cost $6

and a dozen oatmeal cookies cost $7

Find the value of x in the isosceles triangle shown

Answers

Answer:

x = 8√5

Step-by-step explanation:

The large triangle is divided into two smaller ones.  The right one has one leg of length 8, one leg of length x/2, and hypotenuse of length √80.

Appling the Pythagorean Theorem, we can find x:

8² + (x/2)² = (√80)²,

or:                              x^2

64 + x^2/4 = 80, or  ------- = 80

                                    4

Then x^2 = 320 = 64*5.  Taking the square root of both sides, we get:

x = 8√5

Step-by-step explanation:

Normally, there's a list of possible answers associated to this question, and the answer is usually in the form of  -1.5x − 3.5y = -31.5 (equivalent to  y = (-3/7)x + 9)

You forgot to provide the reference image which is essential to answer the question, but I managed to find it... and attach it to my answer.

In the given equation for AB, if we place the y term on the left and x term on the right, we see the slope of that line is 7/3 (y = (7x - 21.5)/3 ==> 7/3x).

We see on the image that the line PQ is perpendicular to AB.  That means that its slope is -3/7.

So, we have a slope  of -3/7 and we know it passes through point P (7,6), let's see if we can find the missing term.

y = (-3/7) x + b

6 = (-3/7) 7 + b

6 = -3 + b

b = 9

So the equation of the line forming the street PQ is y = (-3/7)x + 9

-104=-2(1+7x)-4 answer​

Answers

Add 4 to both sides

-104 + 4 = -2(1 + 7x)

Simplify -104 + 4 to -100

-100 = -2(1 + 7x)

Divide both sides by -2

-100/-2 = 1 + 7x

Two negatives make a positive

100/2 = 1 + 7x

Simplify 100/2 to 50

50 = 1 + 7x

Subtract 1 from both sides

50 - 1 = 7x

Simplify 50 - 1 to 49

49 = 7x

Divide both sides by 7

49/7 = x

Simplify 49/7 to 7

Switch sides

Answers

Answer:60

Step-by-step explanation:40/8 =5 so that means he can walk 5 dogs per hour and if you times 5 by 12 you get 60 as your answer.

Answer:

Ken can walk 60 dogs in 12 hours.

Step-by-step explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other, the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So, [tex]x=\frac{c*b}{a}[/tex]

In this case it is direct magnitudes, so that the three direct rule can be applied as follows: if Ken can walk 40 dogs in 8 hours, how many Ken dogs can he walk in 12 hours?

[tex]number of dogs=\frac{12 hours*40 dogs}{8 hours}[/tex]

number of dogs= 60

So, Ken can walk 60 dogs in 12 hours.

The price of a flight was increased by 3% to £720. What was the price before the increase?
Give your answer to the nearest penny.

Answers

Step-by-step explanation:

let the price be x before increased.

After it is increased then it becomes 1.03x

i.e. 1.03x= 720

x=699.03 which is the price after it is increased.

The question is an illustration of percentage increase, and the price before the increase is £699

How to determine the initial price?

The given parameters are:

Initial = x

Rate = 3%

New price = £720

The equation of the initial price is:

x * (1 + rate) = New price

So, we have:

x * (1 + 3%) = 720

Evaluate the sum

x * 1.03 = 720

Divide both sides by 1.03

x = 699

Hence, the price before the increase is £699
