If in Central city, there are 29791 registered voters and 93 voting centers, then each voting centers serves about 320 of the city population.
Total number of registered voters in Central city = 29791 voters
Total number of voting centers = 93 voting centers
The number of population serves by each center = Total number of registered voters in Central city ÷ Total number of voting centers
Substitute the values in the equation
The number of population serves by each center = 29791/93
= 320.33
≈ 320
Hence, If in Central city, there are 29791 registered voters and 93 voting centers, then each voting centers serves about 320 of the city population.

Given:
The measure of angle of arrc SQ is 160°.
The measure of angle of arc PR is 102°.
The objective is to find the measure of angle x.
Since, the angle x is away from te center of the circle.
Then, the formula to find the value of angle x is,
[tex]x=\frac{PR+SQ}{2}[/tex]Now, substitute the given values in the above formula.
[tex]\begin{gathered} x=\frac{102+160}{2} \\ =\frac{262}{2} \\ =131\degree \end{gathered}[/tex]Hence, the value of x is 131°.
Sean weighs 10 lb more than twice Brad’s weight. If Brad gains 10 lb, together they will weigh 230 lb. How much does each weight now?
Using equations the weight of both Sean and Brad is 156 lbs and 73 lbs.
What do we mean by equations?The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.as in 3x + 5 = 15, for example.There are many different types of equations, including linear, quadratic, cubic, and others.The three primary forms of linear equations are point-slope, standard, and slope-intercept.
So, the weight of Sean and Brad.
Let, Brad, be 'x'.Then Sean be '2x + 10'So, the equation will become:
x + 2x + 10 = 230
Now, solve this equation for 'x' as follows:
x + 2x + 10 = 2303x = 230 - 103x = 220x = 220/3x = 73.33Rounding off: 73 lbs
Then,
Brad weights ⇒ 73 lbsSean weights ⇒ 2(73) + 10 = 156 lbsTherefore, using equations the weight of both Sean and Brad is 156 lbs and 73 lbs.

The variables we need to use in the question are defined. We will call the price of a knife as [tex]k[/tex] and the price of a spoon as [tex]s[/tex].
The total price of [tex]12[/tex] spoons and [tex]16[/tex] knives is then given. Let's write knives instead of [tex]4[/tex] spoons.
[tex]12s+16k=105.64[/tex][tex]3k+16k=105.64[/tex][tex]k=5.56[/tex] per knife.===================================================
Explanation:
k = cost of one knife
s = cost of one spoon
costs are in pounds
12s = cost of 12 spoons
16k = cost of 16 knives
12s+16k = 105.64 pounds is the total cost
We can replace k with 4s because of the phrasing "a knife is 4 times the cost of a spoon". Whatever s might be, quadruple it and it leads us to the value of k.
So,
12s+16k = 105.64
12s+16(4s) = 105.64
12s+64s = 105.64
76s = 105.64
s = 105.64/76
s = 1.39 pounds is the cost of one spoon
k = 4s = 4*1.39 = 5.56 pounds is the cost of one knife
----------------------
Check:
1 spoon = 1.39 pounds
12 spoons = 12*1.39 = 16.68 pounds
1 knife = 5.56 pounds
16 knives = 16*5.56 = 88.96 pounds
12 spoons + 16 knives = 16.68+88.96 = 105.64 pounds total
This fully verifies the answer.

Given the function:
f(x)=x²-3x - 4
Find the following values.
a) f(2)
f(2)=
b) f(4)
ƒ(4)=
c) f(-3)
ƒ(-3) =
The values of f(2), f(4) and f(-3) for the function, f(x) = [tex]x^{2} -3x-4[/tex], are -6, 0 and 14 respectively.
According to the question,
We have the following information:
f(x) = [tex]x^{2} -3x-4[/tex]
Now, to find the values of each function we will put the values in place of x.
We will find the value of f(2) by putting 2 in place of x.
f(2) = [tex](2)^{2} -3(2)-4[/tex]
f(2) = 4-6-4
f(2) = -2-4
f(2) = -6
(We know that the numbers with negative sign are added but the result always remains in negative.)
We will find the value of f(4) by putting 4 in place of x:
f(4) = [tex](4)^{2} -3(4)-4[/tex]
f(4) = 16-12-4
f(4) = 4-4
f(4) = 0
Now, we will find the value of f(-3) by putting -3 in place of x:
f(-3) = [tex](-3)^{2} -3(-3)-4[/tex]
f(-3) = 9+9-4
f(-3) = 18-4
f(-3) = 14
Hence, the values of f(2), f(4) and f(-3) are -6, 0 and 14 respectively.

A survey was given to people who own a sertain car. What percent of the people surveyed were completely satisfied with the car
The percent of the people surveyed were completely satisfied with the car is 55%.
How to calculate the percentage?Number of people completely satisfied = 1155
Number of people somewhat satisfied = 755
Number of people not satisfied = 190
Total number of people = 1155 + 755 + 190 = 2100
Therefore, the percent of the people surveyed were completely satisfied with the car will be:
= Number of people completely satisfied / Total number of people × 100
= 1155 / 2100 × 100
= 55%

a ladder 10 feet long rests against a vertical wall. let be the angle between the top of the ladder and the wall, and let be the distance from the bottom of the ladder to the wall. if the bottom of the ladder slides away from the wall, how fast does change with respect to when ?
Rate of change of x with respect to [tex]\alpha[/tex] when [tex]\alpha =\frac{\pi }{3}[/tex] is 5ft/s.
Since the ladder is 10ft long resting against a vertical wall.
Let the angle between the top of the ladder and the wall is [tex]\alpha[/tex] .
And let the distance from the bottom of the ladder to the wall is x.
Thus we need to find the rate of change of x with respect to [tex]\alpha[/tex] when [tex]\alpha =\frac{\pi }{3}[/tex]
Consider L to be the length of the ladder.
Then, L = 10ft
Thus, we get the relation between the angle and distance x i.e.
x = L [tex]\sin \alpha[/tex]
On differentiating the above equation,
[tex]\frac{dx}{dt} =L \cos \alpha[/tex]
Now after putting the values [tex]\alpha =\frac{\pi }{3}[/tex] in above equation, we get,
[tex]=(10)\cos(\frac{\pi }{3} )=(10)(\frac{1}{2} )=5[/tex]
Therefore, [tex]\frac{dx}{dt} =5[/tex] ft/s

Find the area of ABC with verticles A(4,-3), B(9,-3) and C(10,-11)
Answer:
Step-by-step explanation:
The area of the triangle when the vertices of the triangle are given can be calculated by the following formula:
Area of triangle = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)| where the vertices are A(Ax, Ay), B(Bx, By), C(Cx, Cy)
Now, we have been given the values of vertices as A(4, -3) B(9,-3) , and C(10, −11)
Therefore,
By applying the formula and substituting the given values, we get
Area = 0.5 * |4 * (-3 + 11) + 9 * (-3 + 11) + 10 * (-3 - 3)|
Area = 0.5 * |44|
Area = 22
Hence, the area of triangle ABC with the given vertices is 22 square units

There are 125 people in a sport centre.
59 people use the gym.
70 people use the swimming pool.
55 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
17 people use the gym and the track.
6 people use all three facilities.
A person is selected at random.
What is the probability that this person doesn't use any facility?
Probability that the person selected at random from the sport centre of 125 people is a fraction of 1/4 or 0.25.
Probability of an eventThe probability of an event is the fraction of the required number of outcome divided by the number of possible outcomes.
We shall determine the answer to the question as follows;
People in the sport centre = 125
People who used the 3 facilities = 6
People who accessed only gym = 59 - (6 + 11 + 19) = 26
People who accessed only track event = 55 - (6 + 11 + 24) = 14
People who accessed only swimming pool event = 70 - (6 + 19 + 24) = 21
People who accessed only gym and swimming pool events = 29 - 6 = 19
People who accessed only gym and track events = 17 - 6 = 11
People who accessed only swimming pool and track events = 30 - 6 = 24
Total number of people who accessed at least any one of the facilities = 121
The number of people who did not access any of the facility = 125 - 121 = 4, which is the number of possible outcomes for our required outcome.
Therefore, the probability that the person selected doesn't use any facility = 1/4
