The value for X, the measure of angle MKL, is not specifically given in the question. Since angle JKL is a straight angle of 180 degrees, X can be any value up to 180 degrees.
Explanation:In mathematics, a straight angle is defined as an angle of 180 degrees. In the scenario described with angle JKL, it is mentioned that this is a straight angle. Given that angle MKL is a part of the straight angle, its degree measure X is a component of those 180 degrees. The specific value of X is not given in the question, and it can be any number less than or equal to 180, provided the other part of the angle KJM is equal to 180- X.

The measure of angle MKL is 60 degrees.
Finding the Measure of Angle MKL
To determine the value of X in this problem, we first need to understand that a straight angle measures 180 degrees. The problem states that angle JKL is a straight angle, so:
Angle JKL = 180 degrees
Next, we have the measure of angle JKM given as 120 degrees. Since angle JKL is made up of angle JKM and angle MKL, we can set up the following equation to find the measure of angle MKL, which is X:
Angle JKM + Angle MKL = Angle JKL
Substituting the known values:
120 degrees + X = 180 degrees
To find X, subtract 120 degrees from both sides:
X = 180 degrees - 120 degrees = 60 degrees
Therefore, the measure of angle MKL is 60 degrees.

THE FIRST PIC IS THE QUESTION!!!!
Answer:
a) Error: Moving the decimal point without changing the exponent changes the value of the number. The final number reported is different from the one computed.
b) Correct work: (see below)
... Correct solution: 1.035×10¹¹
Step-by-step explanation:
a) When the decimal point is moved to the left in the mantissa, its value is divided by 10 for each place the decimal point is moved. To keep the overall value of the number the same, the power of 10 must be increased to compensate. The increase in the exponent is the number of places the decimal point is moved left.
In this problem, the decimal point is moved 1 place left, so the exponent needs to be increased from 10 to 11.
b) Correct work:
[tex]\displaystyle(7.14\cdot 10^{10})+(3.21\cdot 10^{10})=(7.14+3.21)\cdot 10^{10}\\\\=10.35\cdot 10^{10}=1.035\cdot 10^{11}[/tex]

y = [tex]\frac{3}{2}[/tex] x + 3
calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = 2, 7 ) and (x₂, y₂ ) = (- 1, 3 )
m = [tex]\frac{3-7}{-1-2}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
calculate m using the gradient formula
with (x₁, y₁ ) = (- 4, - 3) and (x₂, y₂ ) = (0, 3 )
m = [tex]\frac{3+3}{0+4}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]
the line crosses the y-axis at (0, 3 ) hence c = 3

Write the equation of the line parallel to the given line and passing through the given point. y= 1/2 x+2 through (0,4)
Parallel lines have the same slope, so the slope of the new line is 1/2.
The line passes through (0,4), and this gives the y-intercept, which would equal 4.
The equation now would be: y = 1/2x + 4
HHELLLP IDEK HOW TO DO THIS THIS IS DUE TODAY!!!!!
The slope is 8/5 because you are increasing 8 units in the y axis and 5 units in the x direction. So the equation here would be d = 8/5t which means for every increase in t by 1, d will increase by 8/5.

1. y = 3 x
y = -8x
2. y = - 7x
y =-4x - 12
(1)
both equations express y in term of x, hence equate the right sides
- 8x = 3x ( subtract 3x from both sides )
- 11x = 0 ( divide both sides by - 11 )
x = 0
substitute x = 0 into y = 3x → y = 0
solution is : (x, y ) → (0, 0)
(2)
both equations express y in terms of x, hence equate the right sides
- 4x - 12 = - 7x ( add 7x to both sides )
3x - 12 = 0 ( add 12 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into y = - 7x → y = - 28
solution is : (x, y ) = (4, - 28 )

1 0.338
2 0.418
3 0.152
Answer:
A.
Yes, the table shows a probability distribution.
Step-by-step explanation:
Given that a sociologist randomly selects single adults for different groups of three. And the random variable x is the number in the group who say that the most fun way to flirt is in person.
Since sample size is only 3, x cannot be more than 3.
So x can take values as 0 1 2 3
Prob distribution is given as
x P(x)
0 0.092
1 0.338
2 0.418
3 0.152
We find that x values are from 0 to 3.
Each probability is positive but less than 1.
Also total probability = 1
So this is a perfect probability distribution.
A.
Yes, the table shows a probability distribution.
Gina is making pancakes for breakfast. Each batch of pancakes calls for 1/4 of a teaspoon of salt. Gina has 9/10 of a teaspoon of salt left. How many batches of pancakes can she make?
Divide the total amount she has by how much she needs per batch.
When dividing fractions, flip the second one over and then multiply straight across.
9/10 / 1/4 becomes: 9/10 x 4/1
9/10 x 4/1 = 36/10 = 3 6/10 = 3 3/5
She can make 3 more batches and have 3/5 of a teaspoon left over.
half the quotient of a number and 3 is ten. find the number.
call that number x.

What method would you choose to solve the equation 2x2 – 7 = 9? Explain why you chose this method.
I would add 7 to get ...
... 2x² = 16
then divide by 2 to get
... x² = 8
Now, I would take the square root, recognizing that both positive and negative values will solve the problem.
... x = ±√8
The root can be simplified, so we have ...
... x = ±2√2
_____
The above method seemed the most obvious method to me. One could use the quadratic formula, but that seems to involve more operations.
... 2x² -16 = 0 . . . . subtract 9
... x = (-0 ± √(0² -4·2·(-16)))/(2·2) . . . . put the coefficients into the formula
... x = ±(√128)/4 = ±√8 = ±2√2 . . . . . simplify the result
Sample Response/Explanation: I would use the square root property of equality. Because there is no x term, I would just add and divide to get x2 by itself. Then I would take the square root.
The graph of an inequality has a closed circle at 2.6, and the ray moves to the left. What inequality is graphed?
x Greater-than-or-equal-to 12
A closed circle is used on the graph.
The arrow on the graph points right.
The inequality representation is x ≤ 2.6 and has been graphed.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of before example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given,
The graph of inequality has a closed circle at 2.6, and the ray moves to the left.
The closed circle represents that point x = 2.6 is included.
Suppose the variable is x then x ≤ 2.6 represents the inequality.
Hence "The inequality representation is x ≤ 2.6 and has been graphed".

A kite is flying on 39 feet of string. How high is it above the ground if it’s height is 22 feet more than the horizons distance from the person flying it. Assume that the string is being held at ground level.
Answer:
about 36.3 feet
Step-by-step explanation:
Let x represent the height of the kite in feet. Then (x-22) is the horizontal distance to the kite. The Pythagorean theorem tells you the string length is related to these distances by ...
... 39² = x² + (x-22)²
... 2x² -44x -1037 = 0 . . . . rearrange to standard form
Using the quadratic formula, the positive solution is ...
... x = (-b+√(b²-4ac))/(2a) . . . . for a=2, b=-44, c=-1037
... x = (44 + √((-44)² -4(2)(-1037)))/(2·2)
... x = 11 + √639.5 ≈ 36.288
The kite is about 36.3 feet above the ground.
if the x-intercept (–68, 0), and the y-intercept (0, –34), what is the equation?
y = - [tex]\frac{1}{2}[/tex] x - 34
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 68, 0 ) and (x₂, y₂ ) = (0, - 34 )
m = [tex]\frac{-34-0}{0+68}[/tex] = [tex]\frac{-34}{68}[/tex] = - [tex]\frac{1}{2}[/tex]
the y-intercept = (0, - 34 ) ⇒ c = - 34
y= - [tex]\frac{1}{2}[/tex] x - 34
Answer:
Y=-.5x-34
Step-by-step explanation:
this is because you can do y2-y1/x2-x1 to get slope
-34/68
Which equals one half so currently
Y=-1/2x
To get the y intercept we can look at the number when x=0 so it would be -34. So here is the equation
Y=-.5x-34

While in college, why did Euler work through advanced math books on his own? His father required it. The quality of education offered was not satisfactory. His teacher advised it because he did not have time to tutor Euler privately. He wanted to come up with a method that would help builders find the best arrangement for a ship’s masts.
The correct answer is "His teacher advised it because he did not have time to tutor Euler privately." I just did the assignment and got it correct.
While in college, Euler work through advanced math books on his own because his teacher advised it because he did not have time to tutor Euler privately.
Leonhard Euler was a renowned Swiss mathematician who made significant contributions to various branches of mathematics. While in college, Euler worked through advanced math books on his own not because of his father or the quality of education, but because his tutor, Johann Bernoulli, advised it. Bernoulli recognized Euler's talent and encouraged him to pursue mathematics independently, as Bernoulli did not have enough time to tutor Euler privately.
