solve 11kx+13kx=6 for x
The solution of the equation 11kx+13kx= 6 is x = 1/(4k)
The given equation is 11kx+13kx = 6
To solve this equation first we have to take x as common and rearrange the equation, so we can group the like terms together
x(11k+13k) = 6
Add the like terms in the equation
x(24k) = 6
Move 24k to the right hand side of the equation
x = 6/(24k)
Here we have to simplify the value of x, for that we have to divide 6 by 24k in the equation
x = 1/(4k)
Hence, the solution of the equation 11kx+13kx= 6 is x = 1/(4k)

Step-by-step explanation:
1. What value of x makes this equation true?
X/2-2= X/4+4
A. 4
B. 8
C. 16
D. 24
Please help me anyone :'( it would mean a lot!
The x value of 24 makes the equation to be true
How to determine the value of x in the equation?The equation is given as
x/2 - 2 = x/4 + 4
Add 2 to all sides of the equation
So, we have
x/2 = x/4 + 6
Subtract x/4 from all sides of the equation
So, we have
x/2 - x/4 = 6
Multiply through by 4
So, we have
2x - x = 24
So, we have
x = 24
Hence, the value of x in the equation is 24

0.6054 is the probability that at least eight but no more than thirteen of the college graduates plan to pursue a graduate degree.
What are examples and probability?
It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is 12.this is binomial with parameter n=21 and p=0.39
a)
probability = P(X<=5)= ∑x=0x (nCx)px(1−p)(n-x) = 0.1124
b)
probability = P(X=8)= (nCx)px(1−p)(n-x) = 0.1763
c)
probability = P(8<=X<=13)= ∑x=x1x2 (nCx)px(1−p)(n-x) = 0.6054

Demuestra las funciones trigonométricas de 45o a partir de un cuadrado con longitud de lado igual a 1.
The most appropriate choice for trigonometric function will be given by -
sin 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
cos 45° = [tex]\frac{1}{\sqrt{2} }[/tex]
tan 45° = 1
cot 45° = 1
sec 45° = [tex]\sqrt{2}[/tex]
cosec 45° = [tex]\sqrt{2}[/tex]
What are trigonometric functions?
Trigonometric functions are those functions which shows the relationship between side and angle of a right angled triangle.
There are six trigonometric functions-
[tex]sin \theta, cos\theta, tan\theta, cot\theta, sec\theta, cosec\theta[/tex]
[tex]sin \theta[/tex] = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
[tex]cos\theta[/tex] = [tex]\frac{Base}{Hypotenuse}[/tex]
[tex]tan\theta[/tex] = [tex]\frac{Perpendicular}{Base}[/tex]
[tex]cot\theta[/tex] = [tex]\frac{Base}{Perpendicular}[/tex]
[tex]sec\theta[/tex] = [tex]\frac{Hypotenuse}{Base}[/tex]
[tex]cosec\theta[/tex] = [tex]\frac{Hypotenuse}{Perpendicular}[/tex]
Here,
The diagram of the square has been attached with this answer
∠ABC = 90° [Side of a square is 90°}
∠BAC = [tex]\frac{90}{2}[/tex]
= [tex]45[/tex]°
Side of square = 1 unit
Length of diagonal of a square = [tex]\sqrt{2}[/tex] [tex]\times[/tex] side
= [tex]\sqrt{2}[/tex] [tex]\times[/tex] [tex]1[/tex]
= [tex]\sqrt{2}[/tex] units
From [tex]\Delta[/tex] ABC,
sin 45° = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
= [tex]\frac{BC}{AC}[/tex]
= [tex]\frac{1}{\sqrt{2} }[/tex]
cos 45° = [tex]\frac{Base}{Hypotenuse}[/tex]
= [tex]\frac{AB}{AC}[/tex]
= [tex]\frac{1}{\sqrt{2} }[/tex]
tan 45° = [tex]\frac{Perpendicular}{Base}[/tex]
= [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{1}{1}[/tex]
= 1
cot 45° = [tex]\frac{Base}{Perpendicular}[/tex]

In this question, we have been given a scale drawing of a car is presented in the following three scales.
We need to order the scale drawings from smallest to largest.
We know that,
1 cm = 2.54 inch
and 1 meter = 1.1 yards
We know that the metric conversion,
1 meter = 100 centimeters
And 1 cm = 2.54 inch
So, 1 meter = 254 inches
This means, meter is the largest scale and inch is the smallest scale.
1 yd = 91.44 cm

What are Trigonometric Identities?
Trigonometric Identities are equalities that utilize trigonometry functions and hold true for all variables in the equation. There are several trigonometric identities relating to the side length and angle of a triangle.
Given that the value of tan(x) = -4/3 and x is in quadrant 2.
In order to find the value of cos(2x), we can use the trigonometric identity of cos(2x), therefore, for cos(2x) we can write,
\cos(2x) = \dfrac{1-\tan^2(x)}{1+\tan^2(x)}cos(2x)=
1+tan

(x)
1−tan

Since the value of tan(x) is known, substitute the value in the identity,
\begin{gathered}\cos(2x) = \dfrac{1-(-\frac{4}{3})^2}{1+(-\frac{4}{3})^2}\\\\\cos(2x) = \dfrac{1-(\frac{16}{9})}{1+(\frac{16}{9})}\\\\\end{gathered}

cos(2x) = (-7/9) × (9/25)
Cancelling 9 from the numerator and the denominator,

The length of metal flashing needed to be purchase is [tex]1\frac{5}{8}[/tex] feet's.
How to find the length of feet he needs to purchase?He needs 6 ½ feet of metal flashing to complete a household project.
He has two small pieces measuring 3 1/8 feet and 1 3 / 4 feet.
Therefore, the length of metals for him to purchase can be calculated as follows;
The length he has = 3 1 / 8 + 1 3 / 4
The length he has = 25 /8 + 7 / 4
The length he has = 25 + 14/ 8
The length he has = 39 / 8 feet
Therefore
length required to purchase = [tex]6\frac{1}{2} - \frac{39}{8}[/tex]
length required to purchase = [tex]\frac{13}{2}-\frac{39}{8}[/tex]

There are 14 girls and 19 boys in the chess club.
Step-by-step explanation:Let x be girls and y be boys in the chess club. First, we need to write the system.
We know there are 33 students in total.
x + y = 33
We also know there are five more boys than girls in the club.
x + 5 = y
Here is our system of equations and the solving process:x + y = 33
x + 5 = y
First, we will solve for y with substitution:
x + y = 33
x + (x + 5) = 33
2x = 28
x = 14
Now, we will plug in this x-value:
x + y = 33
(14) + y = 33
y = 19

The value of the fraction given as - 1 3/4 - (-8 1/3) - (- 4 1/4) will be 10 5/6.
How to calculate the fraction?It should be noted that a fraction is simply used to represent the numbers that aren't whole.
Based on the information given, the fraction is illustrated as:
= - 1 3/4 - (-8 1/3) - (- 4 1/4)
Note that (-) × (-) = +
Therefore,
= - 1 3/4 - (-8 1/3) - (- 4 1/4)
= - 1 3/4 + 8 1/3 + 4 1/4
The LCM of the denominator is 12
= - 1 9/12 + 8 4/12 + 4 3/12
