Answer:
Multiply the quotient of the number and the total by 360 degrees.
Step-by-step explanation:
If there are three parts that you want to convert to a circle graph (say 12, 9 and 15)
Step 1: Add all the numbers together.
12+9+15 =36
Step 2: Multiply the quotient of each number and the total by 360 degrees.
These are:
[tex]\dfrac{12}{36}\times 360^\circ = 120^\circ\\\dfrac{9}{36}\times 360^\circ = 90^\circ\\\dfrac{15}{36}\times 360^\circ = 150^\circ[/tex]
This is how you convert a number for a part into its corresponding angle measure.

Explain how you determine each of the two expressions of the equation when the mathematical statement is given in words. Explain how you determine each of the two expressions of the equation when the mathematical statement is given in words.
Answer: This can be done by properly interpreting the words into appropriate signs and digits.
Please check below for explanation of WORD PROBLEMS.
Step-by-step explanation: In mathematics, as you move to a higher level, you would encounter more of word problems than simply figures and signs. This simply means, you would be presented with series of statements that should be interpreted and hence an equation would be derived and then solution proffered. First it is really important to note that an equation only exists when the expression on one side is equal to that on the other side. Equally important are the following expressions;
(1) Sum refers to addition (plus)
(2) Difference refers to subtraction (minus)
(3) Product refers to multiplication (times) and
(4) Quotient refers to division (divide)
(5) The same as refers to equal to
Hence, interpreting the expression is largely determined by the use of any of the above expressions and the slightest error in interpreting negates everything afterwards.
So on the one hand, one set of statements will usually tell you that, "so and so is the same as" this and that. This is interpreted as "so and so" is equal to "this and that."
A simple example would help to illustrate this;
Illustration:
(a) Four times a number added to a dozen would result in seven times that same number.
Solution; Let the number be x. Four times a number means 4 times x, which gives you 4x.
Added to a dozen means you add 4x to a dozen, that is 4x + 12.
This would result in seven times that same number. Simply put, what you just did above (4x + 12) would result in or would be equal to 7 times x which is 7x. This now gives you,
4x + 12 = 7x.
Therefore to determine each of the two expressions of an equation is largely dependent on properly interpreting the words into the appropriate signs and figures (that is, plus, minus, times, divide and equal to).
Please! Can someone help me with this task I do not understand?
Answer:
Given
Hope this helps
Step-by-step explanation:
The task explains how to draw a circle. So first attach a thumbtack in between the paper. This will be the midpoint of the circle
Tie one end of thread to it and the other end to a pencil. So when you travel the pencil around, a circle will be formed.
The length from one end of the circle to the other end (which pases the centre) is the diameter. Half of that is the radius
Circumference is the length around the circle which is πd
An easier way to draw the circle is by simply using a compass instead.
A company sells two versions of an antivirus software. The home edition costs $23.50, and the business edition costs $58.75. Last week, the company earned $29,668.75 from selling 745 copies of the software.
If x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold, which system of equations represents this situation?
Answer:
x + y = 745
23.50x + 58.75y = 29,668.75
Step-by-step explanation:
Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:
x + y = 745
Since the home edition costs $23.50, and the business edition costs $58.75:
The money earned from home edition is = 23.50x
The money earned from business edition is = 58.75y
Since the company earned $29,668.75:
23.50x + 58.75y = 29,668.75
What is ? 5(x+y)-3(x+y)
Answer:
2(x+y)

Answer:
Option (1)
Step-by-step explanation:
As we know, sum of an infinite geometric series,
[tex]S=\frac{a}{1-r}[/tex]
Here a = first term of the series
and r = common ratio.
If |r| < 1 Series converges
If |r| ≥ 1 Series diverges
For Option (1),
S = 262 + 301.3 + 346.5.........
Common ratio = [tex]\frac{301.3}{4.2}[/tex] = 1.15
Since |r| = 1.15 > 1
Series will diverge
Option (2),
S = 4.2 + 3.57 + 3.0345..........
Common ratio = [tex]\frac{3.57}{4.2}[/tex] = 0.85
Since |r| < 1
Series will converge.
Option (3),
S = 6651 + 729 + 81........
Common ratio = [tex]\frac{729}{6651}[/tex] = 0.11
Since |r| < 1
Series will converge.
Option (4),
S = 100, 50, 25...........
Common ratio = [tex]\frac{50}{100}=\frac{1}{2}[/tex]
Since |r| < 1
Series will converge.

Which compound inequality is represented by the graph?
-5 4 -3 -2 -1 0 1 2 3 4 5
Answer: x < -2 or x ≥ 4.
Step-by-step explanation:
In the graph, we can see that our set of numbers includes:
All the numbers larger than 4, and the 4 itself (because we have a colored dot in the 4)
Then this range of values can be represented with:
x ≥ 4.
(because this allows x to be larger than 4, or equal than 4)
Our set also includes all the numbers smaller than -2, where the -2 is not included because we have a white dot in the -2.
This can be represented as:
x < -2
Then our set can be described with:
x < -2 or x ≥ 4.
Then the correct option is the third one (counting from the top)

Dante's Mom wants to build a fence around their yard. Here are the measurements of the yard. What are the measurements of the missing side of the yard? How long will the fence be.
Answer:
(a)The missing measurements are 9 feet and [tex]16\frac{1}{4}$ feet[/tex].
(b)Therefore, the length of the fence is [tex]97\frac{1}{2}$ feet[/tex]
Step-by-step explanation:
The diagram of the yard is attached below.
(a)I have labeled the missing dimensions of the yard as x and y.
Therefore:
[tex]y+8\frac{1}{4}=17 \frac{1}{4}\\y=17 \frac{1}{4}-8\frac{1}{4}\\y=9$ feet[/tex]
Similarly:
[tex]x+15\frac{1}{4}=31\frac{1}{2}\\x=31\frac{1}{2}-15\frac{1}{4}\\x=31-15+\frac{1}{2}-\frac{1}{4}\\x=16+\frac{1}{4}\\x=16\frac{1}{4}$ feet[/tex]
The missing measurements are 9 feet and [tex]16\frac{1}{4}$ feet[/tex].
(b)Length of the Fence
The fence is rectangular shaped with:
Length = [tex]31\frac{1}{2}$ feet[/tex]
Width = [tex]17 \frac{1}{4}$ feet[/tex]
Perimeter of a Rectangle = 2(L+W)
Therefore, the length of the fence
[tex]=2(31\frac{1}{2}+17 \frac{1}{4})\\=2(31+17+\frac{1}{2}+ \frac{1}{4})\\=2(48+ \frac{3}{4})\\=96+\frac{3}{2}\\=97\frac{1}{2}$ feet[/tex]
A group of 4 friends like to bowl together, and each friend keeps track of his all-time highest score in a single game. Their high scores are all between 180 and 220, except for Adam, whose high score is 250.Adam then bowls a great game and has a new high score of 290 How will increasing Adam's high score affect the mean and median?
Answer:
The mean will increase, and the median will stay the same.
Step-by-step explanation:
We know that the mean of scores is the average value of the scores of the score obtained by 4 friends.
i.e. it is the ratio of sum of scores of 4 friends to the total number of person i.e. 4.
Hence, if the score of any of the person will increase then the mean will also increase
( Since, the denominator remains the same and the numerator is increasing so , the resultant value will increase )
Also, we know that the median of the score lie between the data set, i.e. the change in the score of the last score won't affect the median :
Since, here we have 4 data points and the median lie between the 2nd and 3rd data point so change in the 4th data point won't affect the median.
Hence, increasing Adam's high score affect the mean and median as:
Mean will increase and Median remains the same.

2 (a) Two mathematically similar containers have heights of 30 cm and 75 cm. The larger container has a capacity of 5.5 litres. Calculate the capacity of the smaller container. Give your answer in milliliter
Answer:
V(small) = 352 milliliters
the capacity of the smaller container is 352 milliliters
Step-by-step explanation:
Given that the two containers are similar, their dimensions follows the same ratio.
Ratio of their length;
Length(smaller) =30 cm
Length(larger) = 75 cm
Ratio = Length(smaller)/Length(larger) = 30cm/75cm
Length Ratio = 2/5
The ratio of their Volumes will be;
Ratio of volume = ratio of length raised to power three.
Rv = Rl^3
Rv = (2/5)^3
Rv = 8/125
The volume of the smaller container;
V(small) = Rv × V(large)
Volume of larger container V(large) = 5.5 litres
substituting the values;
V(small) = 8/125 × 5.5 litres
V(small) = 0.352 litres
V(small) = 352 milliliters
the capacity of the smaller container is 352 milliliters
Which of the following factors of production is unlikely to be found in a

A. Entrepreneurship
B. Land
C. Capital
D. Labor
Option (A) is correct
What are factors of production?
" Factors of production are resources that are the building blocks of the economy; they are what people use to produce goods and services. Economists divide the factors of production into four categories: land, labor, capital, and entrepreneurship."
What are some examples of entrepreneurship as a factor of production?
An entrepreneur is a person who combines the other factors of production - land, labor, and capital - to earn a profit. The most successful entrepreneurs are innovators who find new ways to produce goods and services or who develop new goods and services to bring to market. Without the entrepreneur combining land, labor, and capital in new ways, many of the innovations we see around us would not exist. Entrepreneurs are a vital engine of economic growth helping to build some of the largest firms in the world as well as some of the small businesses in your neighborhood. Entrepreneurs thrive in economies where they have the freedom to start businesses and buy resources freely.

19
-----------
78^2 = 6084.
We observe that 78^2 < 6203.
79^2 = 6241.
We observe that 79^2 > 6203.
Hence the number to be added to 6203 is 6241 - 6203 = 38.
6203 + 38 = 3241
= 79 * 79
= 79.
Therefore 38 should be added to 6203 to obtain a perfect square.

what is the distance between ( -3, -4) and ( 6, -4) on the coordinate plane
Answer:
The distance between (-3, -4) and (6, -4) is 9 units.
Step-by-step explanation:
First, we must know the distance formula between two points.
[tex]Distance(d)=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We will use (-3, -4) for (x₁, y₁) and we will use (6, -4) for (x₂, y₂).
[tex]Distance=\sqrt{(6-(-3)^2+(-4-(-4))^2)}[/tex]
[tex]Distance=\sqrt{(9)^2+(0)^2}[/tex]
[tex]Distance=\sqrt{81+0}[/tex]
[tex]Distance=9[/tex]
So, the distance between the two points is 9 units.
