Answer: 13.79%
Step-by-step explanation:
Amount spent on broadcast TV advertisement = $10000
Amount spent on cable TV advertisement = $15000
Amount spent on radio advertisement = $4000
Total amount spent advertisement = $10000 + $15000 + $4000 = $29000
The Percentage of radio advertisement done will be:
= (Amount spent on radio advertisement / Total amount spent advertisement ) × 100
= (4000 / 29000) × 100
= 13.79%

The polygons are similar. Find the value of x
Ayudemen porfavor . Determine 4 ala potencia x + 4 ala potencia -x, si se sabe que 2ala potencia x + 2 ala potencia -x =3
Answer:
Es igual a 7.
Step-by-step explanation:
Ok, sabemos que:
[tex]2^x + 2^{-x} = 3[/tex]
Queremos calcular:
[tex]4^x + 4^{-x}[/tex]
Tambien sabemos que 4 = 2*2
Entonces:
[tex]4^x + 4^{-x} = (2*2)^x + (2*2)^{-x}[/tex]
y sabemos que 2*2 = 2^2
Entonces:
[tex]4^x + 4^{-x} = (2*2)^x + (2*2)^{-x} = (2^2)^x + (2^2)^{-x}[/tex]
y ahora podemos usar la relación:
[tex](a^n)^m = (a^m)^n = a^{m*n}[/tex]
entonces:
[tex](2^2)^x + (2^2)^{-x} = (2^x)^2 + (2^{-x})^2[/tex]
Ahora podemos completar cuadrados sumando y restando el termino:
[tex]2*(2^x)*(2^{-x})[/tex]
Asi tendremos:
[tex](2^x)^2 + (2^{-x})^2 = (2^x)^2 + (2^{-x})^2 + 2*(2^x)*(2^{-x}) - 2*(2^x)*(2^{-x}) = (2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x})[/tex]
Entonces de momento tenemos que:
[tex]4^x + 4^{-x} = (2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x})[/tex]
Sabemos que el termino que esta dentro del parentesis es igual a 3.
Y tambien podemos usar la propiedad:
[tex]a^n*a^m = a^{n + m}[/tex]
en el termino de la derecha.
Asi tendremos:
[tex](2^x + 2^{-x})^2 - 2*(2^x)*(2^{-x}) = (3)^2 - 2*2^{x + (-x)} = 9 - 2 = 7[/tex]

Find the equation of a line that is perpendicular to 4x+6y=1 that has a greater y intercept compared to 2x+3y=18
Answer:
4y = 6x + 40
Step-by-step explanation:
The general equation of a straight line is y = mx + b
m is the slope and b is the y-intercept
let us write both equations in this form;
we have this as;
6y = -4x + 1
y = -4x/6 + 1/6
and;
2x + 3y = 18
3y = -2x + 18
y = -2x/3 + 6
So firstly we want to find an equation that is perpendicular to the first
When two lines are perpendicular, their slopes has a product of -1
The slope of the first line is -4/6
let the slope of the line we want be m
As per they are perpendicular;
-4/6 * m = -1
-4m/6 = -1
-4m = -6
m = 6/4
So now, we want the y-intercept greater than that of the second equation which is a y-intercept of 6
we can choose 10
and we have the equation as:
y = 6x/4 + 10
multiply through by 4
4y = 6x + 40

Which of these figures has rotational symmetry?
Please help with 17, 19, and 21 using trigonometry. Thanks!
Which expression is a factor of 9r^2-4r+1
Answer:
There are no real factors for this.
Step-by-step explanation:
We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or
We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.
Let's use the 2nd approach.
Here, a = 9, b = -4 and c = 1.
Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.
Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

The vertices of a quadrilateral in the coordinate plane are known. How can the perimeter of the figure be found?
A) Use the distance formula to find the length of each side, and then add the lengths.
B) Use the slope formula to find the slope of each side, and then determine if the opposite sides are parallel.
C) Use the slope formula to find the slope of each side, and then determine if the consecutive sides are perpendicular.
D) Use the distance formula to find the length of the sides, and then multiply two of the side lengths.
Answer: A
Step-by-step explanation:
We have to find the perimeter of the figure.
For doing so, we have to find the length of all the sides of a quadrilateral
The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula:
after finding length of all the sides, we add the length of each side to get the perimeter.
Use the distance formula to find the length of each side, and then add the lengths.

A box is to be wrapped in a shiny pink decorative paper. The box is 99 inches long, 55 inches wide, and 44 inches high. What is the minimum amount of decorative paper needed to cover the box?
Answer:
24442 square inches of decorative paper
Step-by-step explanation:
To solve for the above question, we have to find the Surface Area of the box. The box is shaped as a Rectangular Prism.
Hence, the formula is given as:
A = 2(wl + hl+ hw)
Where:
Length (l) = 99 inches
Width (w) = 55 inches
Height (h) = 44 inches
=2 × (55×99 + 44×99 + 44×55)
=24442 square inches
Therefore, the minimum amount of decorative paper needed to cover the box is 24442 square inches of decorative paper.

B. No, because 6 and 5 are not congruent.
O C. Yes, because 3 and 6 are congruent.
D. No, because 3 and 5 are not supplementary
Answer:
c
Step-by-step explanation:
The solution is, (c) Yes, because angle 3 and angle 6 are congruent.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
given that,
Angles 3 and 6 are "alternate interior" angles. When those angles are congruent, as these are, then the lines crossed by the transversal are parallel.
we have,
We expect angles 5 and 6 to be supplementary because they are a linear pair.
That fact says nothing about the relationship of line d to line c.
Hence, The solution is, (c) Yes, because angle 3 and angle 6 are congruent.

a number y times fives is at most one hundred
Answer:
20
Step-by-step explanation:
twenty times five is one hundred, so, I hope that's the answer you're looking for
Answer:
y <= 20
Step-by-step explanation:
Since it says a number y, our variable is y.
The number is multiplied by 5 which gives us 5y.
It is at most one hundred which means this is an inequality. It is AT MOST which means that 100 is a possible value. This means that our inequality is:
5y <= 100
Now we divide both sides by 5 to isolate y
y <= 20
There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are red and how many are white?
Answer: red marbles = 140
White marbles = 98
Step-by-step explanation:
Let the number of white marbles be represented by x
Since there are 42 more red marbles in a jar than there are white marbles, red marbles will be: = x + 42
Since there are 238 marbles in the jar, this can be represented in an equation as:
x + x+42 = 238
2x + 42 = 238
2x = 238 - 42
2x = 196
x = 196/2
x = 98
White marbles = 98
Red marbles = x + 42
= 98 + 42
= 140
