Suppose that three out of five voters support a candidate. If 1,240 voters support the candidate, how many voters participated in the election in all? Round your answer to the nearest whole number.
Answer:
2067 voters
Step-by-step explanation:
Suppose that three out of five voters support a candidate.
This means 3/5 votes support a candidate
Let the total number rod candidates be represented as x
If 1,240 voters support the candidate,
how many voters participated in the election in all?
Hence,
3/5 of x = 1240 voters.
3/5 × x = 1240
3x /5 = 1240
Cross Multiply
3x = 1240 × 5
x = 1240 × 5/3
x = 2066.6666667 voters
Approximately to the nearest whole number:
2067 voters

It's time to show off your creativity and marketing skills!
You are going to design an advertisement for a new polynomial identity that you are going to invent. Your goal for this activity is to demonstrate the proof of your polynomial identity through an algebraic proof and a numerical proof in an engaging way! Make it so the whole world wants to purchase your polynomial identity and can't imagine living without it!
You may do this by making a flier, a newspaper or magazine advertisement, making an infomercial video or audio recording, or designing a visual presentation for investors through a flowchart or PowerPoint.
You must:
Label and display your new polynomial identity
Prove that it is true through an algebraic proof, identifying each step
Demonstrate that your polynomial identity works on numerical relationships
Warning! No identities used in the lesson may be submitted. Create your own using the columns below. See what happens when different binomials or trinomials are combined. Square one factor from column A and add it to one factor from column B to develop your own identity.
Column A Column B
(x − y) (x2 + 2xy + y2)
(x + y) (x2 − 2xy + y2)
(y + x) (ax + b)
(y − x) (cy + d)
I'm not entirely sure if the focus of this question is more on marketing or the proof, but I can try to help a bit with the proof.
From what I can tell this is basically asking you to take a polynomial from column A, square it, and then add it to column B, and then simplify it while showing your work in order to create an identity. For example:
(x+y)^2 + (ax+b) =
x^2 + xy + +y^2 + ax+b =
x^2 + ax +y^2 + xy + b
Factor out an x from x^2 + ax and a y from y^2 + xy (you don't have to simplify it this way, I'm just doing it as an example)
x(x+a) + y(y+x) + b
Therefore, (x+y)^2 + (ax+b) = x(a+x) + y(y+x)
I can't really help with making a flier, but hopefully this helps

A spinner is labeled 1 to 10. What is the probability of the spinner landing on a prime number after one spin?
Find the measure of each missing angle.
Answer:
Angles 1 and the angle provided (88°) are supplementary meaning their angles with total 180°. Therefore m<1 +88=180
m<1=92
We can see that by the arrow on the 2 lines that they are parralel and paralel lines form congruent angles. Therefore, the m<64 will equal that of 3
m<3=64
Now, that we have the m<1 and the m<3 we know that the m<2 is 24
This is because the measure of the interior angles of any triangle add up to 180.
92+64+m<2=180
156+m<2=180
m<2=24
Now, we see that the m<3+m<4+81 will total 180°. the m<3 is 64 so:
64+81+m<4=180
145+m<4=180
m<4=35
Now, by using the rule that the measure of the interior angles of any triangle add up to 180 we see that the m<4+m<5+64=180
m<4=35
35+64+m<5=180
99+m<5=180
m<5=81

The probability of exactly 4 bridge construction projects taking place at a time in this state is 0.09.
The average (λ) number of bridge construction projects taking place at a time in the state is 7.The average rate of event occurrences is "λ".λ = 7The given number of event occurrences is "x".x = 4The Poisson distribution is a discrete probability distribution in probability theory and statistics that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and regardless of the time since the last event.The Poisson distribution formula is :P(X = x) = [ (λ^x) * e^(-λ) ] / x!P(X = 4) = [ (7^4) * e^(-7) ] / 4!P(X = 4) = [ (7^4) * e^(-7) ] / 4!P(X = 4) = 0.09Thus, the probability of exactly 4 bridge construction projects taking place at a time in this state is 0.09.To learn more about probability, visit :

You need a 40% alcohol solution. On hand, you have a 520 mL of a 70% alcohol mixture. How much pure water will you need to add to obtain the desired solution?
The 390 ml of pure water will you need to add to obtain the desired solution.
It is required to find how much pure water will you need to add to obtain the desired solution.
What is percentage?A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given:
You know that the current solution is 70% alcohol, so the amount of alcohol present is 70% of 520 = 364
Let x be the amount of water to add. Then the new total amount would be 520 + x. To arrive at a solution that is 40% alcohol, you would want the amount of alcohol to be 40% of the new total.
So...
364 = .40 * (520 + x)
By simplify we get,
364=208+0.40x
364-208=0.40x
156=0.40x
x=390 ml
we must add 390 ml of water to get the 40% solution.
Therefore, the 390 ml of pure water will you need to add to obtain the desired solution.

f/5 = -8
What is f ?
Answer:
The answer would be -40.
Step-by-step explanation:
We have to solve for f.
Are equation given to us is:
[tex]\frac{f}{5} =-8[/tex]
What we do first is multiply both sides by 5.
f = -40
We see that -40 is the answer.
To make sure this is correct, we can plug it in for f and solve.
[tex]\frac{-40}{5}[/tex] = -8
It is correct, so f is equal to -40.

if there are 200 questions and 4 marks for correct answers and -1 for incorrect answer and total marks is 250then what is the number of correct answers
The number of questions answered correctly = 90.
What is a system of linear equations?A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".Now,
Given:
Total number of questions = 200Marks for correct answer = 4Marks for incorrect answer = -1Total marks = 250To find : Number of correct answers = ?
Finding:
Now, assuming that the student attempted and answered all the questions,
Let the number of questions correctly answered be x and incorrectly answered be y.Then,
x + y = 200 (For number of questions) (eqn 1)and 4x - y = 250 (For the marks scored) (eqn 2)Solving the system of linear equations:
For eqn 2, we get that y = 4x - 250
Substituting in eqn 1, we get:
=> x + 4x - 250 = 200
=> 5x = 250 + 200 = 450
=> x = 90
That is, the number of questions answered correctly = 90, the incorrect answers = 200 - 90 = 110.

A skydiver falls 144 feet in three seconds. How far does the skydiver fall per second?
Answer: 48 per second.
Step-by-step explanation:
First start by choosing a number. for example: 20. Then Sum The number 3 times 20 + 20 + 20 = 60. You need to get to 144 so I pass 20 and go to 30. 30 + 30 + 30 = 90. Lets pass and go to 40. 40 + 40 + 40 = 120. Its close. when Im close I Start summing 41, 42 and so on. 48 + 48 + 48 = 144. I reach to 144. So that means 48 is the answer.
