∠IKL and ∠IKC and ∠DLH and ∠JLD are pairs by the Linear Pair Theorem.The angle is Applying the Transitive Property of Congruency and product of m∠IKL + m∠JLD = 180°.Therefore, ∠IKL ≅ ∠DLH by the Congruent Supplements TheoremWhat is the Transitive property of congruence?This states that, if a pair of lines or angles or triangles are said to be congruent to a third line or angle, therefore, the first line or angle or triangle is said to be congruent to the third line or angle.
∠IKL and ∠IKC and ∠DLH and ∠JLD are pairs by the Transitive Property of Congruency. because the two angles and the other side of the angle/triangle are said to be equal to two angles and other side of the other triangle.
∠IKC ≅ ∠JLD, so m∠IKC = m∠JLD and as such angle is Applying the Transitive Property of Congruency because if A =b, and b = c then A = c and therefore, the above is true.

Answer:
127.38
Step-by-step explanation:
The surface area formula for a square pyramid is:
A = a^2 + 2a * sqrt[ (a^2 / 4 ) + h^2 ]
So we input the base height as the a value, and the slant as H)
A = 6^2 + 2(6) * sqrt[ (6^2 / 4 ) + 7^2 ]
When using the exponents we get:
A = 36 + 2(6) * sqrt[ (36) / 4 ) + 49 ]
Then multiply/divide:
A = 36 + 12 * sqrt[ (9) + 49 ]
Then add the value in the sqrt.
A = 36 + 12 * sqrt[ 58 ]
Now, if we find the sqrt of 58, we get: sqrt[ 58 ] ≅ 7.615
A = 36 + 12 * 7.615
When multiplying we get:
A = 36 + 91.38
Finally, after adding, the surface area of the square pyramid is:
A = 127.38

What is Probability ?
Probability is the measure of likelihood of an event.
For a Normal Distribution ,
the z-score formula is given by
[tex]\rm Z = \dfrac{X - \mu }{\sigma}[/tex]
Here [tex]\rm \mu\\[/tex] is the mean and [tex]\rm \sigma\\[/tex] is the standard deviation .
It is the measure of the deviation of the data from its central tendency.
Each z-score has a probability value.
It is given in the question that
Mean of 2.16% = [tex]\rm \mu\\[/tex] = 2.16
Standard deviation of 1.36% means that [tex]\rm \sigma\\[/tex] = 1.36
For Sample of 31 the value of standard deviation is [tex]\rm s = \dfrac{\sigma}{\sqrt{n}}[/tex]
s = 1.36/√31
s = 0.2442
Substituting the values
Z = (2.6 -2.16)/0.2442
Z =1.8

inches tall and shaped like a rectangular prism. The bottom layer will be 12 inches long and 10 inches wide. The middle layer will be 10 inches long and 8 inches wide. The top layer will be 8 inches long and 6 inches wide.
What will the total volume of the wedding cake be?
Write your answer as a whole number, proper fraction, or mixed number.
Answers
The total volume of the wedding cake would be 620 in³.
What is the total volume?A rectangular prism is a three-dimensional shape. It also known as a cuboid.
Volume = length x width x height
The volume of the cake is the sum of the volume of the three layers.
Volume of the first layer = 2 1/2 x 12 x 10
5/2 x 12 x 10 = 300 in³
Volume of the second layer = 2 1/2 x 10 x 8
5/2 x 10 x 8 = 200 in³
Volume of the third layer = 2 1/2 x 8 x 6
= 5/2 x 8 x 6 = 120 in³
Total volume = 300 + 200 + 120 = 620 in³

y=
Answers
Answer:
Step-by-step explanation:
We'll look for a line with the form of y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
A parallel line will have the same slope as the reference line, For y=3x-8, the slope is 3. We can write:
y =3x + b for the new line. We need a value of b that will cause the line to include point (6,-4). To find a b that will work, simple use the given point in the above equation and solve for b:
y =3x + b
-4 =3(6) + b for (6,-4)
-4 =18 + b
b = -22
The parallel line that goes through point (6,-4) is y = 3x - 22

Answers
Answer:
$900
Step-by-step explanation:
x = the cost of the tickets
y = the cost of dj & decorations
In the first situation, the profit of -$150 = 75x - y
In the second situation, the profit of $100 = 100x - y
Using the first situation, we isolate y as follows:
-150 = 75x - y
Add y to each side: y-150 = 75x
Add 150 to each side to isolate y
y = 75x + 150
Use this formula in the second situation in place of the y
Original formula: 100 = 100x - y
With substitution: 100 = 100x - (75x + 150)
Simplify to: 100 = 25x - 150
Add 150 to both sides: 250 = 25x
Divide both sides by 25: 10 = x
Input the 10 in for x in either formula above
-150 = 75(10) - y
-150 = 750 - y
Add y to both sides
y - 150 = 750
Add 150 to both sides
y = 900

what is an equation of the line that passes through the point (-4, -6) and is perpendicular to the line 4x+5y=25 ?
Answers
Answer:
5x -4y = 4

An equation for the perpendicular line can be found by swapping the x- and y-coefficients, and negating one of them. The constant changes to a value so that the equation is satisfied at the given point.
__
new lineSwapping the coefficients gives us ...
5x +4y = c . . . . . for some constant c
Negating the y-coefficient (so the x-coefficient remains positive) gives ...
5x -4y = c
constantPutting (x, y) = (-4, -6) into the equation gives us the value of c:
5(-4) -4(-6) = c
-20 +24 = c = 4
