From this we get:
JK = KL
JL = JK + KL
JL= 2JK = 2KL
Here it is given that,
JK = 6x and JL = 13x - 7
JL = 2JK
13x - 7 = 2× 6x
13x - 7 = 12x
x = 7
We have to find the length of JK
JK = 6x

The heights of 10 year old children has a normal probability distribution with mean of 54.6 inches and standard deviation of 5.7 inches. What is the approximate probability that a randomly selected 10-year old child will be more than 51.75 inches tall?
The approximate probability that a randomly selected 10-year-old child will be more than 51.75 inches tall is 0.6915.
How to calculate the probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. From the information, the heights of 10-year-old children have a normal probability distribution with a mean of 54.6 inches and standard deviation of 5.7 inches.
Based on this, the probability that a randomly selected 10-year old child will be more than 51.75 inches tall will be:
P(X > 51.75)
= P(Z > [(number - mean) / standard deviation)]
= P(Z > [(51.75 - 54.6) / 5.7)]
= P(Z > -0.5)
= 1 - P(Z = -0.5)
This will be looked at in the z table.
= 1 - 0.3805
= 0.6915
Therefore, the probability is 0.6915.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example,
Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees. As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
In 177.4 gm of cereal contain 110 calories.
So, 1 gram cereal contain
= 177.4 / 110
= 1.6127
and, 246.5 gm will contain
=246.5 x 1.6127
= 397.5372 calories.
Hence, 397.5372 calories are in 246.5 grams of this cereal.

Find a with the given information.
m=-6/7 (-10,0) and (a,-6)
By using the equation to find the slope, we will see that the value of a is -3.
How to find the value of a?
Here we have two points that define a line.
Remember that a linear equation is of the form:
y = m*x + b
Where m is the slope.
And we know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ - y₁)/(x₂ - x₁)
In this case, we know that the points are:
(-10, 0) and (a, -6), and the slope is m = -6/7, then we can write the equation:
-6/7 = (-6 - 0)/(a + 10) = -6/(a + 10)
The denominator should be the same in both sides, so we must have:
a + 10 = 7
a = 7 - 10 = -3
Then the two points are (-10, 0) and (-3, -6).

4y = -3 Divide both sides by 4
y = [tex]\frac{-3}{4}[/tex]
Answer:

The sentence becomes: "The sum of 4 times y and 5 is 2"
Replace "is" with the equals sign, "="
The sentence becomes: "The sum of 4 times y and 5 = 2"
Replace "times" with the multiply symbol, " * "
The sentence becomes: "The sum of 4 * y and 5 = 2"
Replace "the sum of ___ and ___" with " ___ + ___"

Opposite angles are equal.
x° angle is the opposite angle of the 90° angle.
Therefore, x°=90°.
28)
The 90° angle marked in the figure and the y° angles forms a linear pair.
Hence, both angles are supplementary. Supplementary angles sum upto 180°.
Therefore, we can write
[tex]\begin{gathered} y\degree+90\degree=180\degree \\ y\degree=180\degree-90\degree \\ y\degree=90\degree \end{gathered}[/tex]Therefore, y°=90°.
29)
In the figure, let z°+46°=p°.
From figure, we can see that the p° angle is the opposite angle of y° angle.
Since opposite angles are equal, we can write
[tex]\begin{gathered} p\degree=y\degree \\ z\degree+46\degree=y\degree \end{gathered}[/tex]Since from part 28, y°=90°, we get
[tex]\begin{gathered} z\degree+46\degree=90\degree \\ z\degree=90\degree-46\degree \\ z\degree=44\degree \end{gathered}[/tex]Therefore, zh=44e.

From figure,

3000 for 2 years at 2% compounded quarterly
Based on the given parameters, the amount of the investment after 2 years is $3123
How to determine the amount?The given parameters about the compound interest are
Principal Amount, P = $3000
Interest Rate, R = 2%
Time, t = 2
Number of times, n = 4 i.e quarterly
Compound interests are different from simple interest, and they are calculated using the following compound interest formula
CI = P(1 + R/n)^nt - P
To calculate the amount, we have:
A = P + CI
So, the equation becomes
A = P + P(1 + R/n)^nt - P
Evaluate the like terms
A = P(1 + R/n)^nt
Substitute the known values in the above equation
A = 3000 * (1 + 2%/4)^(2 * 4)
Express 2% as decimal
A = 3000 * (1 + 0.02/4)^(2 * 4)
Evaluate the sum
A = 3000 * (1.005)^8
Evaluate the exponent
A = 3000 * 1.041
Evaluate the product
A = 3123
Hence, the value of the investment is $3123

x° +100° = 180°
x = 80 . . . . . . . . . divide by °, subtract 100
Angle sum theoremThe angle sum theorem tells you that the sum of angles in a triangle is 180°.
y° +62° +80° = 180°
y = 38 . . . . . . . . . . . . divide by °, subtract 142
In the other triangle, the same relation holds:

What is the slope of the line that passes through the points (10, 4)(10,4) and (7, 3)(7,3)? Write your answer in simplest form.
The slope of the line that passes through points (10,4) and (7, 3) is 1/3
Here we are dealing with a slope of a line where a slope of a line is the change in the y coordinate with regard to the change in the x coordinate. If P(x1,y1) and Q(x2,y2) are the two points on a straight line, at that point the slope formula is given by:
m = Change in y-coordinates/Change in x-coordinates
m = (y₂– y₁)/(x₂ – x₁)
Since we are given two points (10,4) and (7, 3), where x₁ and x₂ are 10, 7 whereas y₁ and y₂ are 4, 3
From the formula we get,
m = (y₂-y₁)/(x₂-x₁)
= ( 3-4)/(7 - 10)
= -1/-3
