The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 21.7 square centimeters. The
Perimeter of the octagon is 48 centimeters.
Answers
The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
In a triangle, the sum of all three angles is 180°
Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.
Given the octagon with a perimeter of 48 cm
Let's say the length of each side is a
Perimeter = 8a
8a = 48
a = 6cm
Now,
The area of the triangle is given by
A = 1/2 × Base × Height
A = 1/2 × 6 × h
A = 3h
Now
A = 3h and the area is 21.7 cm²
So,
h = 21.7/3 = 7.23 cm
Hence "The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm".

You decide to market your own custom computer software. You must invest $3,255 for computer hardware, and spend $2.90 to buy and package each disk. If each program sells for $13.75, write a system of equations and determine how many disks you must sell to break even.
Answers
Answer:
13.75x = 3,255 + 2.90x
Step-by-step explanation:
Given that,
Amount invested on computer hardware = $3,255
Amount invested to buy and package each disk = $2.90
Selling price for each program = $13.75
We need to find the equation that is used to find how many disks you must sell to break even. Let there are n disks that you must sell.
ATQ,
$3,255 is a fixed amount. $2.90 and $13.75 depends on x.
So,
13.75x = 3,255 + 2.90x
We can solve the above equation to find the no. of disks.
13.75x - 2.90x = 3255
10.85x = 3255
x = 300
Hence, you must sell 300 disks to break even.

I have a half-full bottle of water and it has more than 8 ounces in it. What would be the expression
Answers
Answer:
The equivalent expression is [tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex].
Step-by-step explanation:
The best approach consists in translating the sentence given in the question into mathematical terms until an expression is complete:
(i) I have a half-full bottle of water
Translation: I use a bottle with a maximum volume capacity [tex]V_{max}[/tex], measured in ounces, a half of it is full of water:
[tex]\frac{1}{2}\cdot V_{max}[/tex]
(ii) And it has more than 8 ounces in it
Translation: The volume occupied by the water is greater than 8 ounces. Hence, we get the following inequation:
[tex]\frac{1}{2}\cdot V_{max} > 8\,oz[/tex]

Costs of homes can be very different in different parts of the United States. a. A 450-square-foot apartment in New York City costs $540,000. What is the price per square foot? Explain or show your reasoning. b. A 2,100-square-foot home in Cheyenne, Wyoming, costs $110 per square foot. How much does this home cost? Explain or show your reasoning.
Answers
Answer:
The cost of homes per square foot differs in different part of the United states. The cost of homes per square foot is gotten by using the formula:
cost of homes per square foot = Cost of apartment / area of apartment
1) Cost of apartment = $540000, area of apartment = 450 ft²
cost of homes per square foot = Cost of apartment / area of apartment = $540000/ 450 ft² = $1200 / ft²
2) cost of homes per square foot = $110/ ft², area of apartment = 2100 ft²
cost of homes per square foot = Cost of apartment / area of apartment
$110 / ft² = Cost of apartment / 2100 ft²
Cost of apartment = $110 / ft² × 2100 ft² = $231000

My equation equals 180. With the 3 variables missing
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, and it needs additional information before it can be answered.
However, a possible question could be that we generate an equation that has 3 variables and equals 180.
A possible question is:
The sum of three consecutive numbers is 180. What is the highest number?
And the solution is as follows:
Let the three numbers (in order of smallest to greatest) be x, y and z
So, the sum is:
[tex]x + y + z = 180[/tex]
Since the numbers are consecutive, then the following relationship exist:
[tex]y = x + 1[/tex]
[tex]x = x + 2[/tex]
Substitute x + 1 for y and x + 2 for z in [tex]x + y + z = 180[/tex]
[tex]x + x + 1 + x + 2 = 180[/tex]
Collect Like Terms
[tex]x + x + x = 180 - 3[/tex]
[tex]3x = 177[/tex]
Solve for x
[tex]x = 177/3[/tex]
[tex]x = 59[/tex]
The value of the highest being is:
[tex]z = x + 2[/tex]
[tex]z = 59 + 2[/tex]
[tex]z = 61[/tex]
You can generate as many equation as possible

Answers
Answer:
The remainder is 4.
Step-by-step explanation:
Note: This question is not correctly stated. It is therefore correctly restated before answering the question as follows:
When 17 is divided by k; where k is a positive integer less than 17, the remainder is 3. What is the remainder when the sum of the possible values of k is divided by 17?
The explanation of the answer is now given as follows:
Since k < 17, it implies that the possible values of k must be from between 1 and 16 inclusive.
Between 1 and 16, only 7 or 14 will give a remainder of 3 when either of them is used to divide 17. Therefore, 7 and 14 are the possible values of k.
Therefore, we have:
Sum of the possible values of k = 7 + 14 = 21
Also, we have:
Sum of the possible values of k divided by 17 = 21 / 17 = 1 with a remainder of 4.
Therefore, the remainder is 4 when the sum of the possible values of k is divided by 17.
In the worlds coolest freezer sodium gas was cool to temperature of 78.5 below zero and then called 194.65 more what was the new temperature of the sodium gas

[tex]-273.15^{\circ}\text{C}[/tex]

[tex]T_i[/tex] = Initial temperature of sodium gas = [tex]-78.5^{\circ}\text{C}[/tex]
[tex]\Delta T[/tex] = Change in temperature of sodium gas = [tex]-194.65^{\circ}\text{C}[/tex]
[tex]T_f[/tex] = Final temperature of sodium gas
Change in temperature of gas is given by
[tex]\Delta T=T_f-T_i\\\Rightarrow T_f=\Delta T+T_i\\\Rightarrow T_f=-194.65+(-78.5)\\\Rightarrow \Delta T=-273.15^{\circ}\text{C}[/tex]

A company loses $5,400 as the result of a manufacturing defect. Each of the 8 owners have agreed to contribute an equal amount, x, to help pay for the losses.
Part A
Which expression shows the total loss after the owners contribute some money?
Answers
Answer:
x=$5400:8
$5400:8x = total loss after the owners contribution
The expression shows the total loss after the owners contribute some money is 8x = 5400
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount contributed by each owner as loss.
Since there are 8 owners sharing a loss of $5400, hence:
8x = 5400
x = 675
The expression shows the total loss after the owners contribute some money is 8x = 5400

- 7x – 4y = -44
7x - 3y = 16
Answers
Answer:
{x,y} = {5,8}
Step-by-step explanation:
[1] 7x-3y+5=16
[2] 4y=3x+17
[1] 7x - 3y = 11
[2] -3x + 4y = 17
// Solve equation [2] for the variable y
[2] 4y = 3x + 17
[2] y = 3x/4 + 17/4
// Plug this in for variable y in equation [1]
[1] 7x - 3•(3x/4+17/4) = 11
[1] 19x/4 = 95/4
[1] 19x = 95
// Solve equation [1] for the variable x
[1] 19x = 95
[1] x = 5
// By now we know this much :
x = 5
y = 3x/4+17/4
// Use the x value to solve for y
y = (3/4)(5)+17/4 = 8
