Phoenix has 11200 registered voters. There are two candidates for city council in an upcoming election: A and B. The day before the election, a telephone poll of 400 randomly selected registered voters was conducted. 138 said they'd vote for A, 228 said they'd vote for B, and 34 were undecided. We will assume the actual voting results will be proportional to this survey.
This voter sample suggests that we might expect ______________of the 11200 registered voters to vote for A.

solve this 59 + x = 24
Hey there!
=> 59 + x = 24
=> x = 24 - 59
=> x = -35
Therefore, 59 + (-35) = 24
Answer:
[tex]\boxed{\sf{x=-35}}[/tex]
Step-by-step explanation:
A subtraction property of equations is the subject of this problem.
For the correct answer, you need to isolate x from one side of the equation.
59+x=24
First, switch sides.
x+59=24
Then, subtract by 59 from both sides.
[tex]\sf{x+59-59=24-59}[/tex]
Solve.
[tex]\sf{24-59=-35}[/tex]
[tex]\boxed{\sf{x=-35}}[/tex]
Therefore, the solution is x=-35, which is our answer.
I hope this helps you! Let me know if my answer is wrong or not.
solve this 100 - x = 24
Answer: -0.24
first you would take 100 and minus it from both sides giving you -x=0.24 then you divide the negative from both sides giving you -0.24.

a 12. A bicycle wheel has a radius of 40 cm. How many times does it revolve during a journey of 10 km? Give your answer to the nearest 100. [For T, use either your calculator value or 3.142.
The bicycle wheel revolving is a illustration of circumference
The bicycle wheel revolves 4000 times
How to determine the number of times?The given parameters are:
Radius (r) = 40 cm
Distance =10 km
Start by calculating the circumference of the wheel
[tex]C =2\pi r[/tex]
This gives
[tex]C =2 * 3.142 * 40[/tex]
[tex]C =251.36[/tex]
The number of times to cover a distance of 10 km is then calculated as:
[tex]n =\frac{10km}{251.36cm}[/tex]
Evaluate the quotient
[tex]n =3978.35773[/tex]
Approximate
[tex]n =4000[/tex]
Hence, the bicycle wheel revolves 4000 times

1. Devon is young and has just graduated college with her associate's degree. She plans to start saving money for retirement as soon as she starts her new job. By taking 10% of her monthly gross income, Devon is able to contribute (a) $ $587 each month to a retirement plan. The account is expected to earn interest with an APR of 5.25% compounded monthly. Round answers to two decimal places. How much money will be in Devon's retirement account if she continues to make the same monthly investment for 40 years
Using the future value formula, it is found that $546,148,903,191,724.25 will be in Devon's account.
What is the future value formula?It is given by:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
In which:
P is the payment.n is the number of payments.r is the interest rate.In this problem, the parameters are as follows: P = 587, r = 0.0525, n = 40 x 12 = 480.
Hence:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
[tex]V(480) = 587\left[\frac{(1 + 0.0525)^{480-1}}{0.0525}\right][/tex]

System of Linear EquationsSystem of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.
For solving this equation, firstly, rewrite the information given:
[tex]\frac{p-5}{q-5}=\frac{9}{1} \;(1)\\ \\\frac{p+20}{q+20}=\frac{7}{3} \;(2)[/tex]
From equation 1, you have:
[tex]p-5=9q-45\\ \\ p=9q-40[/tex]
And from equation 2, you have:
[tex]3*(p+20)=7*(q+20)\\ \\ 3p+60=7q+140\\ \\[/tex]
Now, substitute p=9q-40 in 3p+60=7q+140
[tex]3p+60=7q+140\\ \\3*(9q-40)=7q+140\\ \\ 27q-120=7q+140\\ \\ 20q=20\\ \\ q=10[/tex]
If q=10 for p=9q-40, you will have:
[tex]p=9q-40\\ \\ p=9*10-40\\ \\ p=90-40\\ \\ p=50[/tex]
Therefore, the ratio [tex]\frac{p}{9}[/tex] is equal to [tex]\frac{50}{9}[/tex].

The sum of a number x and 4 is less than 12.
Which of the following inequalities represents this
statement?
Answer:
x+4<12
Step-by-step explanation:
You did not put the inequalities, but that is how the statement would look like. "And" is a clue that we're adding. So, x + 4 would be the first part, and we know when the open part of this symbol '</>' is pointed at a number then that number is greater than the number before it. So, in this case, you'll want to have that symbol pointed at 12 because x + 4 is less than 12.

all you really need to do is find the common denominator and it'll get you an answer for the numerator.
Answer:
13/15
Step-by-step explanation:
You first need to find the common denominator between both 3 and 5, so you have to find the number that would be the best, which is 15. Then you have to multiply the numerator by how many times you went up for that number, for 2/3 would be times 5, and 1/5 would be times 3. Doing this will get you your answer, 13/15.

one leg of a right triangle is 21 centimeters long. The hypotenuse of the triangle is 29 centimeters long. What is the length of the unknown leg?
Answer:
20 cm
Step-by-step explanation:
A2 + B2 = C2
C is your hypotenuses = 29 cm
And one leg of a right triangle is 21 cm long
So we have A2 = (21cm)2 = 441 cm + B2 = (29cm)2 = 841cm
B2 = 841 - 441 = 400
B = √400 = 20
So the third leg of a triangle that has a hypotenuses of 29 cm and one side of a right triangle that is 21 cm long is 20 cm
