The parts of the triangles Ebony needs to compare so as to make sure both triangles are congruent by SAS are;
[tex] \overline{EG} [/tex] and [tex] \overline{OM}[/tex]What are congruent triangles?Two triangles are said to be congruent when the three sides and three interior angles of one triangle have the same measure as the three sides and the three interior angles of the other triangle.
The given triangles are ∆MON and ∆GEF
The segments and angles that Ebony has ensured are congruent are;
[tex] \overline{EF} \cong \overline{ON}[/tex]

The method by which Ebony intends to use to make sure that the two triangles are congruent, SAS, Side–Angle–Side congruency postulate.
The Side–Angle–Side congruency postulate states that two triangles are congruent if two sides and an included angle in one triangle are congruent to the corresponding two sides and included angle in the other triangle.
Given that the sides that form included angles with [tex] \angle{ MON} [/tex] are [tex] \overline{ON}[/tex] and [tex] \overline{OM}[/tex] and the sides that form an included angle with [tex] \angle{ GEF}[/tex] are [tex] \overline{EF} [/tex] and [tex] \overline{EG} [/tex], the other segments Ebony needs to compare are therefore the segments;

a couple has four children. neither the father nor the mother is bald; one of the two sons is bald, but neither of the daughters is bald. (a) if one of the daughters marries a nonbald man and they have a son, what is the chance that the son will become bald as an adult? (b) if the couple has a daughter, what is the chance that she will become bald as an adult?
If one of the daughters marries a non-bald man and they have a son, the chance that the son will become bald as an adult is 0%
If the couple has a daughter, the chance that she will become bald as an adult is 0%
In the question, we have been given that the neither the father nor the mother is bald, and out of the four children only one son is bald, but the other son and the two daughters are not bald, now we solve the following:
Part a
A chance that the son will become bald as an adult:
If the daughter has no bald gene (XX), and she marries a non bald man then there is 0% chance that the son will become bald as an adult because neither the mom nor the dad has the baldness gene
Part b
The chance that she will become bald as an adult:
If the daughter having a bald gene ([tex]X^{b} X[/tex]) marries a non bald (XY)man then also there is a 0% chance that the daughter will be bald as an adult. As the baldness is a recessive trait, for the daughter to be bald she needs to have two baldness gene( one from father and one from mother). And since this is not the case the daughter might have baldness gene but the phenotype will be non-bald.

when an integer is subtracted from 8 times the next consecutive integer, the difference is 71. Find the vale of the greater integer.
The value of the greater integer will be 10.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The algebraic expression is,
'' An integer is subtracted from 8 times the next consecutive integer, the difference is 71.''
Now,
Let a number = x
Then, Its consecutive number = (x + 1)
So, We can formulate;
⇒ 8 (x + 1) - x = 71
Solve for x as;
⇒ 8x + 8 - x = 71
⇒ 7x + 8 = 71
⇒ 7x = 71 - 8
⇒ 7x = 63
⇒ x = 9
Thus, The value of greater number = x + 1
= 9 + 1
= 10
Therefore, The value of the greater integer will be 10.

Garcia's bike rentals, it cost $38 to rent a bike for 9 hours. How many hours of bike use does the customer get per dollar. If necessary, round the answer to the nearest hundredth
From the question, we were told that Garcia's bike rentals cost $38 to rent bike for 9 hours.
We are to find how many hours will a customer use the bike per dollar.
This can also be likened to calculating miles per gallon.
if i can drive 300 miles on 10 gallons of gas then my miles per gallon is 300/10 = 30 mpg.
So, hours per dollar is also a division problem too.
(9 hours)/($38)
= 9/38
= 0.2368
= 0.24 hours per dollar (to the nearest hundredth)
Wasif spent 1/3 of his income on housing and 2/5 on daily expenditure and save the rest if he save 24600 what was his income altogether
Answer:
61500
Step-by-step explanation:
1/3 = 3/15
2/5 = 6/15
1 - 3/15 - 6/15 = 6/15
6/15 = 24600
24600 ÷ 6 × 15 = 61500
Answer:
92250
Step-by-step explanation:
Forming algebraic equation and solving:
Let the income = x
Amount spent on housing = (1/3) of the income
[tex]\sf = \dfrac{1}{3}x[/tex]
Amount spent of daily expenditure = (2/5) of the income
[tex]\sf =\dfrac{2}{5}x[/tex]
Income = Savings + housing expenditure + daily expenditure
Income - housing expenditure - daily expenditure = savings
[tex]\sf x - \dfrac{1}{3}x-\dfrac{2}{5}x=24600\\\\\\\dfrac{x*15}{1*15}-\dfrac{1*5}{3*5}x-\dfrac{2*3}{5*3}x = 24600\\\\\\[/tex]
[tex]\sf \dfrac{15}{15}x-\dfrac{5}{15}x-\dfrac{6}{15}x = 24600\\\\\\\dfrac{(15 -5 - 6)}{15}x = 24600[/tex]
[tex]\sf \dfrac{4}{15}x = 24600[/tex]
[tex]\sf x = 24600 *\dfrac{15}{4}\\\\ x = 6150*15[/tex]
Income = 92250

solve each linear equation 7+2x=4x-3
Answer:
Simplifying
7 + 2x = 4x + -3
Reorder the terms:
7 + 2x = -3 + 4x
Solving
7 + 2x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
7 + 2x + -4x = -3 + 4x + -4x
Combine like terms: 2x + -4x = -2x
7 + -2x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
7 + -2x = -3 + 0
7 + -2x = -3
Add '-7' to each side of the equation.
7 + -7 + -2x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + -2x = -3 + -7
-2x = -3 + -7
Combine like terms: -3 + -7 = -10
-2x = -10
Divide each side by '-2'.

Write the perimeter of the triangle as a simplified polynomial. Then factor the polynomial.
Answer:
4x² + 29x + 7 = (4x + 1)(x + 7)
Step-by-step explanation:
Simplify the polynomial:Like terms are terms with same variable and same power.
Perimeter = sum of all the sides
= 3x² + 1 + 15x + 6 + x² + 14x
= 3x² + x² + 15x + 14x + 1 + 6
Combine like terms,
= 4x² + 29x + 7
Factorize:
Sum = 29
Product = 4*7 = 28
Factors = 1 , 28 {28 + 1 = 29 & 28*1 = 28}
Rewrite the middle term using the factors,

The probability of that the first 40 feet in a roll contain no flaws is ≈ .3012
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. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
CalculationΘ = μ = [tex]\frac{100 foot}{3 flaws}[/tex]
a ) We assume that the length until the first flaw follows an exponential distribution.
Probability density function of exponential distribution:
f(x) = [tex]\frac{1}{Θ} e^{\frac{-x}{Θ} } = \frac{1}{100/3}e^{-x/(100/3)} = \frac{3}{100}e^{-3x/100}[/tex]
The first 40 feet in a roll of 100 feet contain no flaws if the first flaw occurs after 40 feet.

Pattern x: Starting number: 3, Rule: add 3Pattern y: Starting number: 6, Rule: add 6For pattern x, we have the following highlights:
Start = 3
Rule = Add 3
This means that the nth term of pattern x is:
Pattern x = 3 + 3x
For pattern y, we have the following highlights:
Start = 6
Rule = Add 6
This means that the nth term of pattern y is:
Pattern y = 6 + 6y
The complete tableFor pattern x, set x = 0, 1, 2 and 3
So, we have
3 + 3x = 3 + 3(0) = 3
3 + 3x = 3 + 3(1) = 6
3 + 3x = 3 + 3(2) = 9
