Given: Δ L M N is isos. with LM ≅ NM , and MO bisects ∠L M N .
Prove: Δ M L O ≅ ΔM N O
It is proved that ΔLMN is an isosceles triangle.
What exactly do we mean by a triangle's congruency?Two triangles are said to be congruent if all three corresponding sides are equal and all three corresponding angles are equal in measure.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are repositioned, they will coincide.If two triangles satisfy the five congruence conditions, they are congruent.They are side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side (RHS).So,
Given:
LM ≅ NMMO bisects ∠L M NTo prove congruency:
MO = MO (Common line)LM = NM = Given∠LM0 = ∠NMO = equal angles (As MO bisects ∠LMN)Therefore, ΔM LO ≅ ΔMNO under SSA congruency.
Since the 2 sides are similar so the angles in front of them will also be similar.So we can say that ΔLMN is an isosceles triangle.Therefore, it is proved that ΔLMN is an isosceles triangle.

FITNESS A fitness instructor is starting a new aerobics class using fitness hoops. She, wants to confirm that all of the hoops are the same size. What measure(s) can she use to prove that all of the hoops are congruent? Explain your reasoning.
The instructor can use Mathematical coincidence to prove that all of the hoops are congruent.
What do we mean by Mathematical coincidence?The term "coincide" refers to something happening at the same time. In mathematics, coincident lines are lines that lie on top of each other so that when we look at them, they appear to be a single line rather than double or multiple lines. Two lines as well as shapes that are exactly on top of one another.For instance, these two lines are coincidental, but they appear to be one line because they are on top of each other.So, the fitness instructor should use Mathematical coincidence and should keep the hoops on one another to check the congruency.

The monthly cost of using a cell phone is $29.95 plus $0.035 per minute of talk time. An equation to
represent this monthly cost would be:
C = 29.95 + 0.035x, where C represents the monthly cost and x represents the number of minutes used.
How many minutes were used during a month if the cost amounted to $43.53 ?
O 506 minutes
O 426 minutes
O 388 minutes
438 minutes
Answer:
c) 388 minutes
Step-by-step explanation:
Given equation,
→ C = 29.95 + 0.035x
Then the call duration will be,
→ C = 29.95 + 0.035x
→ 43.53 = 29.95 + 0.035x
→ 0.035x = 43.53 - 29.95
→ x = 13.58/0.035
→ [ x = 388 ]
Hence, option (c) is correct.
If p(a|b) =0.40, p(b) = 0.74, and p(a) = 0.42, are the events a and b independent?
The set of items that exist as part of both sets A and B exists at the intersection of the two sets.
If p(a|b) =0.40, p(b) = 0.74, and p(a) = 0.42, then P(A∩B) is 0.46.
What is Probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
It exists given that the Probability of two independent event A and B exists given by P(A) and P(B).
The intersection of event A and B is given by P( A∩B).
The group of items that are part of both sets A and B is the intersection of the two sets. A ∩ B represent the intersection. The symbol "∩" can be used to represent the intersection of sets.
The collection of all outcomes that are components of both sets A and B is known as the intersection of events A and B (abbreviated AB).
Given: P(a|b) = 0.40
P(A) = 1 - 0.40 = 0.6
P(B) = 1 - 0.74 = 0.26
P(A∪B) = P(A) + P(B) − P(A∩B)
substitute the values in the above equation, we get
0.40 = 0.6 + 0.26 - P(A∩B)
- P(A∩B) = 0.40 - 0.6 - 0.26
P(A∩B) = 0.46
Therefore, the independent events of A and B exists 0.46.

Urijah is starting a food cart business. The cost to start the business is $20,000 and the monthly costs are $8,000. He has been earning $8,800 every month in revenue. In how many months will Urijah's business break-even and earn a profit?
He will break even on the 25th month.
How to find the number of month his business will break even?The cost to start the business is $20,000 and the monthly costs are $8,000.
He has been earning $8,800 every month in revenue.
Profit = Selling Price - Cost Price
Therefore,
let
x = number of month
Hence,
selling price = 8800x
cost price = 20000 + 8000(x) = 20,000 + 8000x
Therefore,
profit = 8800x - (20,000 + 8000x)
profit = 8800x - 20000 - 8000x
profit = 8800x - 8000x - 20000
profit = 800x - 20000
Hence,
The month when they will break even is as follows:
8800x = 20,000 + 8000x
20000 = 8800x - 8000x
20000 = 800x
x = 20000 / 800
x = 25
Therefore, he will break even on the 25th month.

Find the value of x if A C=4 x-3, D C=2 x+9, m∠ E C A=15 x+2, and EC is a median of ΔAED. Is EC also an altitude of Δ A E D ? Explain.
If AC = 4x - 3, DC = 2x + 9, m ∠ ECA = 15x + 2, and EC is a median of ΔAED then EC is not an altitude of ΔAED because of m ∠ ECA = 92.
What is meant by the altitude of a triangle?
In geometry, an altitude is a line that passes through two very specific points on a triangle: a triangle's vertex, or corner, and its opposite side at a right, or 90-degree, angle. The base is the opposite side. Triangles have three vertices and three opposite sides in common.
Given: AC = DC
4x - 3 = 2x + 9
4x - 2x - 3 = 2x - 2x + 9
simplifying the above equation, we get
2x - 3 = 9
2x - 3 + 3 = 9+3
2 x = 12
x = 6
Substitute the value of x in m ∠ ECA, then we get
m ∠ ECA = 15x + 2
= 15(6) + 2
m ∠ ECA = 92
EC is not an altitude of ΔAED because of m ∠ ECA = 92.
Therefore, EC is not an altitude of ΔAED.

What is the slope of a line perpendicular to the line whose equation is x+4y=16x+4y=16. Fully simplify your answer.
The slope of a line perpendicular to the line of x + 4y = 16 is 4.
What is the slope of a line perpendicular to the line of the given equation?Given the equation of line;
x + 4y = 16
First, rearrange in slope intercept form ( y = mx + b ) by solving for y
x + 4y = 16
Subtract x from both sides
x - x + 4y = 16 - x
4y = -x + 16
Divide each term by 4 and simplify
4y/4 = -x/4 + 16/4
y = -(1/4)x + 4
Using the slope intercept form ( y = mx + b ) to compare.
y = -(1/4)x + 4
Slope m = -(1/4)
Now, the equation of a perpendicular line to y = -(1/4)x + 4 must have a slope that is the negative reciprocal of the original slope.
Hence, m_perpendicular will be;
m_perpendicular = -( 1 / original slope )
m_perpendicular = -( 1 / -(1/4) )
m_perpendicular = -( -4 )
m_perpendicular = 4
Therefore, the slope of a line perpendicular to the line of x + 4y = 16 is 4.

The center and radius of the circle given by the equation x^2 + y^2 - 4y - 16 = 0 is (0 , 2) and 2√5, respectively.
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 4y - 16 = 0, then the coefficients are:
D = 0
E = -4
F = -16
If D = -2h and D = 0, then
0 = -2h
h = 0
If E = -2k and E = -4, then
-4 = -2k
k = 2
If F = h^2 + k^2 -r^2 and F = -16, then

How many total fish did the company catch over the first 10 years, to the nearest whole number?
The company catches 1,237,275.5 fishes over 10 years.
Given that, a company catches 175000 fishes in a year, the population decreases, the number of fish the company was able to catch decreased by 8% each year.

The second year = 175000 × 0.92 = 161000
The third year = 161000 × 0.92 = 148120
The fourth year = 148120 × 0.92 = 136,270.4
The fifth year = 136270.4 × 0.92 = 125368.8
The sixth year = 125268.8 × 0.92 = 115339.3
The seventh year = 115339.3 × 0.92 = 106112.2
