well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.
B)
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x[/tex]
A)
Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.
Final answer:
Dorian's claim is incorrect because dividing 10,200 votes by 30% (or 0.30) gives 34,000 votes, which is the correct total number of votes cast in the mayoral election. Therefore, the calculation shows that the total votes are much higher than Dorian's claim of 3,060 votes.
Explanation:
A. Dorian's claim that the total number of votes cast in the mayoral election was 3,060 is not reasonable because if the losing candidate received 10,200 votes which represented 30%, then the total votes should be much higher than 3,060. To find the total, you would divide the number of votes the candidate received by the percentage they represent.
B. To find the total number of votes cast in the mayoral election, you would set up the equation 10,200 = 0.30 * Total Votes. Dividing 10,200 by 0.30 gives the total number of votes cast, which is 34,000.
Equation: Total Votes = 10,200 votes / 0.30 = 34,000 votes
6! = 3! • 2! = =
Evaluate each expression
Answer:
120
Step-by-step explanation:
! means 3*2*1
so 6*1=6*5*4*3*2*1
6=720
720/6=120
factorial of n is given as
n! = n × (n-1) × (n-2)× . . . . . × 1
so lets solve it
6! = 6 × (6-1) × (6-2) × ( 6-3)×(6-4)×(6-5)
= 6×5×4×3×2×1
=720
similarly
3! = 3×2×1 =6
2!= 2×1= 2
3! × 2! = 6×2= 12

The product of the polynomials 7x - 4 and 8x + 5 is 56x^2 + 3x - 20, attained by applying the FOIL method.
Explanation:The given question asks to find the
product
of two polynomials: 7x - 4 and 8x + 5. The product of two polynomials can be found using the distributive property, also known as the FOIL (First, Outer, Inner, Last) method. So, start by multiplying the first terms of each polynomial: 7x * 8x = 56x^2. Then, multiply the outer terms: 7x * 5 = 35x. Next, the inner terms: -4 * 8x = -32x. And finally, the last term: -4 * 5 = -20. Summing all these gives the final answer: 56x^2 + 3x - 20.

Step-by-step explanation:
use the table of values to write the exponential function
Answer:
[tex]\frac{1}{2}(\frac{1}{4}^x)[/tex]
Step-by-step explanation:
To find the function, compare the y values. Notice that each y value decreases by being divided by 4. This means the base of the exponential is 1/4.
To find the initial value, consider the point (0,0.5). When 1/4 is raised to the 0 power, the value is 1. This leaves that the initial value is 1/2 since 1/2*1 = 0.5.
The function is [tex]\frac{1}{2}(\frac{1}{4}^x)[/tex].
Answer:
The required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].
Step-by-step explanation:
The general exponential function is
[tex]f(x)=ab^x[/tex] .... (1)
where, a is the initial value and b is growth factor.
From the given table it is clear that the function passes through the points (0,0.5) and (-1,2). It means the equation of function must be satisfied by the points (0,0.5) and (-1,2).
Substitute f(x)=0.5 and x=0 in equation (1), to find the value of a.
[tex]0.5=ab^0[/tex]
[tex]0.5=a[/tex]
The value of a is 0.5.
Substitute a=0.5, f(x)=2 and x=-1 in equation (1), to find the value of b.
[tex]2=(0.5)b^(-1)[/tex]
[tex]2=\frac{0.5}{b}[/tex]
[tex]2b=0.5[/tex]
Divide both sides by 2.
[tex]b=\frac{0.5}{2}[/tex]
[tex]b=0.25[/tex]
The value of b is 0.25.
Substitute a=0.5 and b=0.25 in equation (1).
[tex]f(x)=0.5(0.25)^x[/tex]
[tex]f(x)=\frac{1}{2}(\frac{1}{4})^x[/tex]
Therefore the required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].
Please solve this. I'm very confused
Answer:
244.56
Step-by-step explanation:
Alice starts with x amount of money, and then spends 41.52 of it. This means that x-41.52 is equal to the amount of money Alice has left because spending 41.52 means that it is subtracted from the bank account. Thus, x-41.52=203.04 .
Using the additive property of equality, we can add 41.52 to both sides, resulting in x=244.56

If F(x)=2^x +5x and g(x)=3x-5 find (f+g)(x)
Final answer:
The sum of the functions [tex]F(x) = 2^x + 5x[/tex] and g(x) = 3x - 5 is [tex](f+g)(x) = 2^x + 8x - 5[/tex], which is obtained by adding the corresponding elements of each function and combining like terms.
Explanation:
The question asks for the sum of two functions, F(x) and g(x). In mathematical terms, (f+g)(x) means we have to add the functions F(x) and g(x) together. This is done by adding the corresponding elements of each function.
Here are the given functions:
F(x) = 2x + 5x
g(x) = 3x - 5
To find (f+g)(x), we combine them like this:
(f+g)(x) = F(x) + g(x) = (2x + 5x) + (3x - 5)
Now, we simply combine like terms:
(f+g)(x) = 2x + 5x + 3x - 5
(f+g)(x) = 2x + 8x - 5
This is the simplified form of the sum of the functions F(x) and g(x).
Final answer:
To find (f+g)(x) where f(x)=2ˣ + 5x and g(x)=3x-5, you simply add the functions together to get (f+g)(x) = 2ˣ + 8x - 5.
Explanation:
The student has asked to find (f+g)(x) where f(x) = 2ˣ + 5x and g(x) = 3x - 5.
To find (f+g)(x), we add the two functions together:
f(x) = 2ˣ + 5xg(x) = 3x - 5So, (f+g)(x) is:
(f+g)(x) = (2ˣ + 5x) + (3x - 5)
Combine like terms:
(f+g)(x) = 2ˣ + 5x + 3x - 5
(f+g)(x) = 2ˣ + 8x - 5
That is the simplified form of the function (f+g)(x).

Which equations correctly represent a line that has a slope of -2/3 and passes through the points (–2, 8) and (1, 6)?
Answer:
2x + 3y = 20
Step-by-step explanation:
Slope of the line is -2/3 . We can use any of the given points to find the equation of the line. Lets use (1, 6)
The general point-slope form of a line is:
[tex]y-y_{1} =m(x-x_{1} )[/tex]
Here m is the slope which is -2/3
x1 and y1 are the coordinates of the point. So x1 = 1 and y1 = 6
Using these values, we get:
[tex]y-6=-\frac{2}{3} (x-1)\\\\ 3(y-6)=-2(x-1)\\\\ 3y-18=-2x+2\\\\ 2x+3y=20[/tex]
Answer:
2x + 3y = 20
Step-by-step explanation:
We are given two points: (–2, 8) and (1, 6) and the slope (m) of the line and we are to find the equation of this line.
We know that the standard equation of a line is:
[tex]y=mx+c[/tex]
So we will plug in the given values in the above equation to find the y intercept.
[tex]6=-\frac{2}{3} (1)+c[/tex]
[tex]c=\frac{20}{3}[/tex]
So the equation of this line will be:
[tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
or
2x + 3y = 20
Determine which ordered pair is a solution for the system of equations.
Y=5/2x-3
y=-x+3
(12/7, 9/7)
Since y = -x + 3, substitute it into the first equation.
-x + 3 = 5/2x - 3
Now add x and subtract 3 from both sides.
0 = 7/2x - 6
Now add 6 on both sides.
6 = 7/2x
Now divide by 7/2 on both sides.
12/7 = x
Now, just substitute x into the second equation.
y = -12/7 + 3
y = -12/7 + 21/7
y = 9/7

Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
To find x subtract the sum of the 2 given angles from 180, that is
x = 180° - (32 + 52)° = 180° - 84° = 96°
-------------------------------------------------------
x and y form a straight angle, hence
y = 180 - x = 180° - 96° = 84°
------------------------------------------------------
To find z subtract the sum of the 2 angles from 180
z = 180° - (55 + y)° = 180° - (55 + 84)° = 180° - 139° = 41°
--------------------------------------------------------
x = 96°, y = 84°, z = 41° → A
To watch the high school play, theatre goers must buy a ticket at the door. The cost of an adult ticket is $10.00, and the cost of a student ticket is $7.50. If the number of adult tickets sold is represented by a, and the number of student tickets sold is represented by s, which expression represents the amount of money collected at the door from the ticket sales? A. 7.50as B. 7.50(a + s) C. (10.00a)(7.50s) D. 10.00a + 7.50s
Answer: Option 'D' is correct.
Step-by-step explanation:
Let the number of adult tickets sold be 'a'.
Let the number of students tickets sold be 's'.
Cost of an adult ticket = $10.00
Cost of a student ticket = $7.50
According to question, it becomes,
[tex]10.00a+7.50s[/tex]
Hence, option 'D' is correct.
The expression that represents the amount of money collected at the door from the ticket sales is $10a + $7.50s
The total amount collected at the door is the sum of the total cost of adult tickets and children tickets
Total cost of adults ticket = cost per ticket x total number of adults tickets sold
$10 x a = $10a
Total cost of children's ticket = cost per ticket x total number of children tickets sold
$7.50 x s = $7.50s
The total amount collected at the door = $10a + $7.50s

Answer:
A. (2x-3)/2
Step-by-step explanation:
Performing the long division indicated by the perimeter expression, you find ...
perimeter = (2x -3) + (10x +6)/(x^2 +2x)
Comparing this to the formula for the perimeter ...
perimeter = 2W +2L
where L is said to be of the form (ax +b)/(x^2 +2x)
we can match terms in the perimeter expression to see that ...
2W = 2x -3
2L = (10x +6)/(x^2 +2x)
The problem doesn't ask for it, but we can see that (a, b) = (5, 3). We can also see that ...
W = (2x -3)/2 . . . . . . . matches choice A

what is 12 / 2/3 ? nothing pops up when i search it and i have a module exam!
Answer:
18
Step-by-step explanation:
Yur Welcome
The answer to the question [tex]\( \frac{12}{2/3} \) is \( 18 \).[/tex]
To solve the expression [tex]\( \frac{12}{2/3} \)[/tex], need to divide 12 by [tex]\( \frac{2}{3} \).[/tex] Dividing by a fraction is the same as multiplying by its reciprocal. Therefore, we can rewrite the expression as:
[tex]\[ 12 \times \frac{3}{2} \][/tex]
Now, multiply 12 by \( \frac{3}{2} \):
[tex]\[ 12 \times \frac{3}{2} = \frac{12 \times 3}{2} \][/tex]
[tex]\[ \frac{12 \times 3}{2} = \frac{36}{2} \][/tex]
Finally, divide 36 by 2 to get the result:
[tex]\[ \frac{36}{2} = 18 \][/tex]
So, [tex]\( \frac{12}{2/3} = 18 \)[/tex]. This is the value you would use if this calculation appears on your module exam.
Type the correct answer in each box. If necessary, use / for the fraction bar(s). Given: AB || CD . If the coordinates of point A are (8 , 0) and the coordinates of point B are (3 , 7), the y-intercept of AB is _____ . If the coordinates of point D are (5 , 5), the equation of line CD is y = ___ x + ___ .
Answer:
Im not sure about the other 2 but the last box is 12, the answer above is incorrect for PLATO. I just took the test.
The y-intercept of line AB is 0, and the equation of line CD is y = 5.
Explanation:The y-intercept of a line is the point where it intersects the y-axis. In this case, we are given the coordinates of point A as (8, 0). Since the y-coordinate of point A is 0, the y-intercept of line AB is 0.
The equation of a line can be determined using the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept. The slope of line CD can be found by finding the difference in y-coordinates divided by the difference in x-coordinates between points C and D. In this case, the slope is (5 - 5) / (5 - 5) = 0. Therefore, the equation of line CD is y = 0x + b, where b is the y-intercept. Since point D has coordinates (5, 5), the y-intercept is 5. Therefore, the equation of line CD is y = 0x + 5, or simply y = 5.
