Answer:
m<GKH + m<HKI = 180; m<HKI + m<IKJ = 180 - Angles forming a linear pair sum to 180
m<GKH + m<HKI = m<HKI + m<IKJ - Subsitution
m<GKH = m<IKJ - Algebra
<GKH ≅ <IKJ - Definition of congruence
Step-by-step explanation:
Angles that form a linear pair are supplementary because together they make a straight line. So, they must sum to 180.
In statement 2, m<HKI + m<IKJ replaces 180 degrees. This is allowed because m<HKI + m<IKJ is equivalent to 180 degrees, so it can be substituted.
In statement 3, m<HKI is subtracted from both sides. This is allowed through the property of equality, which is a part of algebra.
The definition of congruency is that two shapes that are equal are congruent. So if m<GKH = m<IKJ, then they must be congruent as well.
If 120 L of an acid solution is 75% acid, how much pure acid is there
in the mixture?
Answer:
25% or 30L
Step-by-step explanation:
100% is 120L, we know 75% is acid, we need the other 25% to make the 100%. 25% of 120 is 30, so 30 liters is pure acid

c^2 = 9+26 = 25
c = 5
Answer:
B

40 POINTS PLS HELP I WILL ALSO GIVE BRAINLY (ANSWER THE BOXES ON BOTTOM RIGHT)
Answer: See explanation
Step-by-step explanation:
ΔLNM and ΔLKN are 30°- 60°- 90° triangles
We have to find the length of LN before we can find the length of MN.
In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3
Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.
LN = √3 times the shorter leg
3 × √3 = 3√3
LN = 3√3
We now know the length of the longer leg in ΔLNM (3√3)
MN would be 3√3 × √3
3√3 × √3
= 3√9
= 3 × 3 = 9
MN = 9
ΔLKM is also a 30° - 60° - 90° triangle
The short leg is 6 m
The hypotenuse would be 12 m
The longer leg would be 6√3
Perimeter: 6 + 12 + 6√3
The perimeter is 18 + 6√3
Area: 1/2 × b × h
b = 6√3
h = LN = 3√3
6√3 × 3√3
18√9 = 18 × 3 = 54
Area: 54 m²

What are the advantages and disadvantages of bar chart
Answer:
Advantages:
● Bar charts are pretty easy to interpret, and there's a very clear relationship between size and value that allows easy comparison.
● They're simple to make and most people have experience creating and understanding them from school.
● They can help in presenting very large or very small values more emphatically.
Disadvantages:
● Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant. An alternative to this would be creating an adjusting scale for the bars, but this complicates the visual aspect of the presentation and breaks the intuitive sense that size correlates directly to value.
● Bar graphs tend to be locked into a particular data set, making it hard to show multiple values or changes over time unless the chart is modified, such as by making the bars layered and three-dimensional.

Why?
The interquartile range is a better measure of spread because, The interquartile range is often seen as a better measure of spread than the range as it is not affected by outliers.

The length of a diagonal of a square is 18√2 inches. Find the perimeter of the square.
A diagonal of a square is defined, [tex]d=a\sqrt{2}[/tex] where a is side of the square. Solve for a to get [tex]a=\frac{d}{\sqrt{2}}[/tex].
Now multiply a by 4 since that is the definition of a perimeter,
[tex]P=4a=4\cdot\frac{18\sqrt{2}}{\sqrt{2}}=4\cdot18=\boxed{72}[/tex].
Hope this helps.
for each sequence find the first 4 terms and the 10th term
Answer:For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:
a) 1 (1st term) + 5 = 6
2 (2nd term) + 5 = 7
3 (3rd term) + 5 = 8
4 (4th term) + 5 = 9
10 (10th term) + 5 = 15
And so on for b (not going to keep writing the term, I’m sure you get that by now.
b) 2(1) - 1 = (2x1) - 1 = 1
2(2) - 1 = (2x2) - 1 = 3
2(3) - 1 = (2x3) - 1 = 5
2(4) - 1 = (2x4) - 1 = 7
2(10) - 1 = (2x10) - 1 = 19
Hope this helps :)

Which of the following are solutions to the cubic equation x^3+4x^2+4x=0

Answer:

Step-by-step explanation:
In a particular region, for families with a combined income of $57,000 or more, 12% have no children, 37% have one child, 43% have two children, and 8% have three children. Use this information to construct the probability distribution for X, where x represents the number of children per family for this income group. Arrange x in increasing order and write the probabilities P(x) as decimals.
Answer:
P(X = 0) = 0.12.
P(X = 1) = 0.37.
P(X = 2) = 0.43.
P(X = 3) = 0.08
Step-by-step explanation:
12% have no children
This means that P(X = 0) = 0.12.
37% have one child
This means that P(X = 1) = 0.37.
43% have two children
This means that P(X = 2) = 0.43.
8% have three children.
This means that P(X = 3) = 0.08

the difference between two numbers is 308 328. if the smaller number is 6 524, what is the larger number?
The larger number is 301804
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
The smaller number =6 524,
The difference between two numbers = 308 328
Now,
Let the missing number be x
x-6524=308328
x=308328-6524
x=301804
Therefore, the larger number of algebra will be 301804.

Answer:
x = 8
there is no ∠1
Step-by-step explanation:
The angle sum theorem tells you ...
∠XYW +∠WXZ = ∠XYZ
70° +(5x -4)° = 106°
5x = 40 . . . . . . . . . . . divide by °, subtract 66
x = 8 . . . . . . . . . divide by 5
∠WYZ = 36° . . . . . . . the difference between 70° and 106°
