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? How many beignets were left?
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.

In a math class with 26 students, a test was given the same day that an assignment
was due. There were 17 students who passed the test and 18 students who completed
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?
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]

In the figure below, \overline{XZ}
XZ
start overline, X, Z, end overline is a diameter of circle AAA.
What is the arc measure of minor arc \stackrel{\large{\frown}}{YZ}
YZ
⌢
Y, Z, start superscript, \frown, end superscript in degrees?
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.

Step-by-step explanation:
We have two shapes on a graph and the question is asking for the translation of rhombus QRST to rhombus Q'R'S'T.
Looking at the graph we can see that not only does the rhombus move backwards, but also downward, this indicates that our answers will be in a subtracting symbol.
So all we have to do is count the amount of spaces rhombus QRST went to get to rhombus Q'R'S'T

Solve the system by substitution.
8x – y = 42
-43 - 6 = y
Answer:
x = .875 y = -49
Step-by-step explanation:
(8x - y = 42)
(y = -43 - 6) or (y = -49)
Since we have our y value, we can plug it into our top equation:
8x -(-49) = 42
8x + 49 = 42
-42 -42
8x = 7
/8 /8
x = 0.875
To check the work:
8(0.875) - 49 = 42

model this sine function into a cosine function.
sine function: 67.5sin12(x-7.5)+67.5
Answer:
67.5sin12(x - 7.5) + 67.5
= 67.5[sin 12(x - 7.5) + 1]
= 67.5[sin(12x - 90) + 1]

rectangle has dimensions 12 litre into 6 CM if you draw a square on the same perimeter what will be its area
Answer:
[tex]Area = 81cm^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 12[/tex]
[tex]Width = 6cm[/tex]
Required
Determine the area of a square with the same perimeter
First, calculate the perimeter (P) of the rectangle.
[tex]P=2*(Length + Width)[/tex]
[tex]P=2*(12 + 6)[/tex]
[tex]P=2*18[/tex]
[tex]P=36[/tex]
The perimeter of a square is:
[tex]P = 4L[/tex]
Where L is the side length.
Substitute 36 for P
[tex]36 = 4L[/tex]
Make L the subject
[tex]L =\frac{36}{4}[/tex]
[tex]L =9[/tex]
The area of the square is:
[tex]Area = L^2[/tex]
[tex]Area = 9^2[/tex]
[tex]Area = 81cm^2[/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]

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.
for the following exercises, identify the type of data that would be used to describe a response (quantitative discrete, quantitative continuous, or qualitative), and give an example of the data.
14. distance to the closest movie theater
16. number of competing computer spreadsheet software packages
Answer:
14: quantitative continuous
16: quantitative discrete
Step-by-step explanation:
Distance can be any non-negative real number, hence it is continuous.
The number of packages has to be a positive integer, hence is discrete.
