What radius of a circle is required to inscribe a regular hexagon with an area of 210.44 cm2 and an apothem of 7.794 cm?

Answers

Answer 1
[tex]\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap\quad \begin{cases} a=apothem\\ p=perimeter\\ -------\\ a=7.794\\ A=210.44 \end{cases}\implies 210.44=\cfrac{1}{2}(7.794)p \\\\\\ 420.88=7.794p\implies \cfrac{420.88}{7.794}=p\implies 54\approx p \\\\\\ \textit{a \underline{hexa}gon has 6 sides, so }\cfrac{54}{6}\implies \stackrel{\textit{length of one side}}{9}[/tex]

so.. now, if we know one side is of 9 units long... ok, bear in mind that a regular hexagon, splits the center of the circumscribing circle in 6 even angles, that'd be 60° each, if you run a bisector from that angle, it'd split into two 30° angles, check the picture below.

So it ends with a 30-60-90 triangle with one side being just half of the 9 units, and we can just use the 30-60-90 rule to get the radius itself, which is just one of the sides of the 30-60-90 triangle.
What Radius Of A Circle Is Required To Inscribe A Regular Hexagon With An Area Of 210.44 Cm2 And An Apothem
Answer 2

Answer:

The answer is D) 9cm

6 equilateral triangles in a regular hexagon

210.44

6

= 35.073 cm2

The apothem cuts each equilateral triangle into two right triangles.

35.073

2

= 17.5367 cm2

Base of each right triangle.

area =  

1

2

bh

17.5367 =  

1

2

b(7.794)

b = 4.5

Thus, the sides of each equilateral triangle is 2b = 2(4.5) = 9; which is also the radius of the circle needed to construct the inscribed regular hexagon.

What is the area of a circle 3.102 cm in diameter? (note: the units will be cm2, you only need to enter the number)?

Answers

Area of a circle = pi*r^2, where r is the radius.

r = diameter/2
= 3.102/2
= 1.551

A = pi*1.551^2
= 7.557 cm^2

Area of a circle is pi radius square
diameter= 3.102
radius=diameter/2=3.102/2=1.551
A=3.14 (1.551)^2=7.554cm^2

What is the prime factorization of 15

Answers

15 
3 * 5 <== prime factorization

Answer: 3 × 5

Step-by-step explanation: To find the prime factorization of 15, first create a factor tree with two branches.

Since 15 divided by 3 gives us 5, we know that  and 5 are factors of 15. This means that we can write 3 and 5 at the bottom of our branches.

While 1 and 15 are also factors of 15, we don't use them in our factor tree. This because when finding a prime factorization, we only want factors other than 1 and the number itself.

Next, we circle any prime numbers in our factor tree. Since 3 and 5 are both prime numbers, we circle both 3 and 5. Since we have circles at the bottom of our branches, we are finished.

Therefore, the prime factorization of 15 is 3 × 5.

Answers

This question pertains to the voting options and procedures during a homeowners association meeting, covered under the broader subject of Social Studies in the context of High School education. It involves understanding quorum requirements and voting rules as per bylaws for decision-making on motions.

The question revolves around a homeowners association meeting where a board member has three options to participate in a vote: vote yes, vote no, or abstain from a motion. There are three motions for which each board member must decide how to vote. In such meetings, the rules outlined typically require a quorum to conduct business, the ability to make amendments to bylaws, and procedures for electing members, as seen in various articles of an organization's bylaws and rules of procedure. These rules ensure that the organization conducts its affairs in an orderly and democratic manner, often requiring a majority or unanimous consent for certain actions.

Meetings like these are essential, as they also involve critical decisions such as annual meetings, bylaw amendments, or the dissolution of the organization, each depending on the vote of the board members or the members of the organization. Membership eligibility and voting rights are typically determined by the board of directors or outlined within the bylaws. Furthermore, certain organizational procedures such as elections, member qualifications, and the transparency measures such as keeping a journal of proceedings of each meeting are often mandated.

A college student borrow ​$1,500 for 3 months to pay for a semester of school. If the interest is ​$30.94, find the monthly payment ​(Round to the nearest​ cent.)

Answers

Total amount repayment=amount borrowed+interest

Total amount repayment
1,500+30.94=1,530.94

Monthly payment
1,530.94÷3 months=510.31...answer

Hope it helps!

Answer:

Hence, the monthly payment to the nearest cent is 510.31

Step-by-step explanation:

Consider the provided information,

A college student borrow ​$1,500 for 3 months to pay for a semester of school.

Let us consider the monthly payment is $x.

If he pay $x for next 3 months, then the total amount student paid in 3 month is: 3x

The interest is ​$30.94 for 3 months.

Student pay all the borrowed money and interest in 3 months.

That means he pay $1,500 + $30.94 in 3 months while the monthly payment was 3x.

This can be written as:

[tex]3x = 1500+30.94[/tex]

[tex]3x = 1530.94[/tex]

[tex]x = \frac{1530.94}{3}[/tex]

[tex]x = 510.31[/tex]

Hence, the monthly payment to the nearest cent is 510.31

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angles of the pentagon are equal, which expression represents the measure of two angles?

Answers

there are 5 interior angles  so each angle =

    (40x^2 - 65x + 50)  / 5  =   8x^2 - 13x + 10

so for 2 angles it's  16x^2 - 26x + 20 Answer

Answer:

Expression representing the measure of the two angles of the given regular polygon is 16x² - 26x + 20.

Step-by-step explanation:

Given Expression of the Sum of the all interior angles of a regular polygon

40x² - 65x + 50

We need to find expression representing the measure of the two angles.

We know that regular polygons have all side and all angles equal.

Number of side or angles in regular polygon = 5

So, when we divide given expression by 5 we get expression for an angle of the regular polygon.

[tex]\frac{40x^2-65x+50}{5}=\frac{5(8x^2-13x+10)}{5}=8x^2-13x+10[/tex]

Expression for an angle of regular pentagon = 8x² - 13x + 10

Now, For 2 angles  = 2( 8x² - 13x + 10 ) = 16x² - 26x + 20

Therefore, Expression representing the measure of the two angles of the given regular polygon is 16x² - 26x + 20.

At a store clearance, a women spent less than $200 on shirts that were labeled $15 each . How many shirts did she buy? Identify the numbers that are included in the solution set .

Answers

She bought about 13 shirts.  You just divide the numbers
We know that a women spent less than $200 on shirts.
We also know that the shirt were labeled $15 each, which means the price od each shirt is $15. 
In order to find the number of shirts the women bought  (denoted with X) we should divide the total amount of cash spent with the numbers of shirt she has bought.
X=$200/$15
X=$13.33
Because it is not logical to buy 0.33 shirt (it must be whole), we can conclude that the women bought 13 shirts.

a baker makes cakes and sells them at county fairs his initial cost was $45 to reserve a booth and $25 traveling expenses. He figures that it costs $1.75 to make each cake and he charges $6.50 per cake. Let x represent the number of cakes sold. Express the revenue R and Cost C as functions of x. Then find how many cakes will he need to sell before he will make a profit

Answers

Final answer:

The baker's revenue R can be expressed as R = x * 6.50, and the cost C can be expressed as C = 45 + 25 + (x * 1.75). To find the number of cakes he needs to sell before making a profit, we set the revenue equal to the cost and solve for x. The baker will need to sell at least 15 cakes before making a profit.

Explanation:

To express the revenue R as a function of x, we can use the equation R = x * 6.50. This is because the revenue is the number of cakes sold multiplied by the price per cake. So, every cake sold contributes $6.50 to the revenue.

To express the cost C as a function of x, we can use the equation C = 45 + 25 + (x * 1.75). The initial fixed costs of $45 for reserving a booth and $25 for traveling expenses are added to the variable costs of $1.75 per cake multiplied by the number of cakes sold.

To find the number of cakes he needs to sell before making a profit, we need to set the revenue equal to the cost and solve for x:

R = C => x * 6.50 = 45 + 25 + (x * 1.75)

Combining like terms, we get:

4.75x = 70

x = 70 / 4.75

x ≈ 14.74

Since you cannot sell a fraction of a cake, the baker will need to sell at least 15 cakes before making a profit.
