∆EFJ ≅ ∆HFG
Step-by-step explanation:
Side EF in ∆EFJ ≅ side HF in ∆HFG (corresponding sides)
Side FJ in ∆EFJ ≅ side FG in ∆HFG (corresponding sides)
Also,
<F in ∆EFJ ≅ <F in ∆HFG (vertical angles are congruent)
Thus, two sides and one included angle of ∆EFJ are congruent to two corresponding sides and an included angle of ∆HFG.
Therefore, by the SAS Congruence Theorem, ∆EFJ ≅ ∆HFG.

Answer:
14
Step-by-step explanation:
Sin(∅) = Opposite angle ÷ hypotenuse.
Sin (45) = 7[tex]\sqrt{2}[/tex] ÷ hypotenuse
hypotenuse = 7[tex]\sqrt{2}[/tex] ÷ sin(45)
*********************
Keep in mind
sin(45) = √2÷2
*********************
so we have: Hypotenuse = 7√2 ÷ (√2÷2)
Hypotenuse= 14.

1) (2 points) Imagine a 21-gonal prism. How many total faces does this prism have? Provide a clear
and detailed justification for your answer, using appropriate vocabulary, that does not rely on a
formula.
Answers
Answer: There are 23 faces total.
Explanation:
This is because there are 21 lateral faces, each of which are a rectangle. Then there are the 2 base faces which are each 21-gons. A 21-gon is a 21 sided polygon. So we have 21+2 = 23 faces total.
[tex]\frac{1}{x {}^{2} - 3 } = \frac{ \sqrt{3} }{x + \sqrt{3} } - \frac{2}{ \sqrt{3} - x } [/tex]
can someone please solve this?
Answers
Answer:
[tex]\boxed{\textsf{ The value of x is \textbf{ 8 + 6}$\sqrt{3 }$.}}[/tex]
Step-by-step explanation:
Here we are given a equation which we need today simplify and solve for x .The given equation to us is :-
[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } [/tex]
Let's simplify the equation :-
[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } \\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}-\dfrac{2}{-(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}+\dfrac{2}{x-\sqrt3}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3(x-\sqrt3)+2(x+\sqrt3)}{(x+\sqrt3)(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3x-3+2x+2\sqrt3}{x^2-3}\\\\\sf\implies 1=\sqrt3x-3+2x+2\sqrt3 \\\\\sf\implies \sqrt3x+2x = 4-2\sqrt3\\\\\sf\implies x(\sqrt3 +2)=4-2\sqrt3\\\\\sf\implies x =\dfrac{4-2\sqrt3}{\sqrt3+2}\\\\\sf\implies x =\dfrac{ (4-2\sqrt3)(\sqrt3-2)}{(\sqrt3+2)(\sqrt3-2)}\\\\\sf\implies x =\dfrac{-8-6\sqrt{3}}{3-4}\\\\\sf\implies \boxed{\pink{\sf x =8+6\sqrt3}}[/tex]

Answers
Each of the guests gets 7 beignets and 5 beignets will remain.
Given that,
Tia made 320 beignets for an office Mardi Gras party.
If the 45 guests each ate the same number of beignets how many did each eat and How many beignets were left Is to be determined
In mathematics, it deals with numbers of operations according to the statements.
What is simplification?The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Tia made 320 beignets for an office Mardi Gras party.
Total beignet = 320
number of guests = 45
Each ate the same number of beignets, Divide 320 by 45 the quotient will be the number of beignets eaten by the guest and the remainder will be the remaining beignets
While dividing 320 by 45
Quetient = 7 and remaimnder = 45
Thus, each of the guests gets 7 beignets and 5 beignets will remain.

Answers
Answer:
the answer is 59 (I got it on khan academy)
Step-by-step explanation:
59 degrees is the measures of the minor arc YZ if diameter of a circle is XZ
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that diameter of a circle is XZ
We have to find the measure of arc YZ.
11w+5w+4=180
Add the like terms
16w+4=180
Subtract 4 from both sides
16w=176
Divide both sides by 16
w=176/16
w=11
Now plug in w value of yz
yz=5w+4
=5(11)+4
=55+4
=59 degrees
Hence, 59 degrees is the measures of the minor arc YZ.

the assignment. There were 15 students who passed the test and also completed the
assignment. What is the probability that a student who failed the test completed the
homework?
Answers
Answer:
The propability would be 4/26 students who failed the test but completed the
homework
Step-by-step explanation:
The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur,
Given,
Total number of students = 26 students
Number of students who completed the assignment = 18 students
Number of students who pass the test and also completed the assignment = 15 students
Number of students who completed the assignment and fail the test = 18 -15 = 3 students
Then,
Probability = Number of favorable outcome / Total number of outcome
Probability that a student who failed the test completed the homework = [tex]\frac{3}{26}[/tex]
Hence, The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]

which scatterplot represents the data given in the table which shows the number of apples in bags and the weights of the bags?
Answers
Answer:C
Step-by-step explanation: Because I took the pre test!
The scatterplot that represents the data given in the table is Scatterplot C.
Option C is the correct answer.
What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
From the table,
We see that,
Number of apples = 4 has weight 2lb and 3lb.
Number of apples = 5 has weight 2lb and 3lb.
Number of apples = 6 has weight 3lb and 5lb.
Number of apples = 7 has weight 4lb and 6lb.
Number of apples = 8 has weight 5lb and 7lb.
Now,
We see that in the scatter plot of option C, the table is represented.
Thus,
The scatterplot that represents the data given in the table is Scatterplot B.
