Answer:
DE ≈ 6.97
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos55° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{EF}{DE}[/tex] = [tex]\frac{4}{DE}[/tex] ( multiply both sides by DE )
DE × cos55° = 4 ( divide both sides by cos55° )
DE = [tex]\frac{4}{cos55}[/tex] ≈ 6.97 ( to the nearest hundredth )
in a class of 20 students, how many conversations must be had so that every student talks to every other student in the class?
A) 190
B) 380
C) 760
D) 6840
Answer:
[tex]\text{A) }190[/tex]
Step-by-step explanation:
Similar to the handshake problem, if every student must talk with another person, each student will talk to 19 other students. However, a conversation consists of two people, so we must divide the number of ways we can rearrange the two people ([tex]2![/tex]). Therefore, our answer is [tex]\frac{20\cdot 19}{2!}=\boxed{\text{A) }190}[/tex]

Answer:
Below
Step-by-step explanation:
First, find the difference. You would do
-19 - (-9) = -10
-9 - 1 = -10 and so on...
The difference is -10
Now you need to find what number will make 11 when added to -10.
11 - (-10) = 21
The equation:
y = -10x + 21

Answer:
A. Parallelogram LMNP
B. 33
C. 98°
Step-by-step explanation:
LMNP is a parallelogram.
Adjacent angles of a parallelogram are Supplementary.
[tex] \therefore 82\degree +(3x - 1)\degree =180\degree [/tex]
[tex] \therefore (3x - 1+82)\degree =180\degree [/tex]
[tex] \therefore (3x +81)\degree =180\degree [/tex]
[tex] \therefore 3x +81 =180 [/tex]
[tex] \therefore 3x =180-81 [/tex]
[tex] \therefore 3x =99 [/tex]
[tex] \therefore x =\frac{99}{3} [/tex]
[tex] \therefore x =33 [/tex]
[tex] \implies m\angle N= (3x - 1)\degree=(3*33 - 1)\degree=(99-1)\degree = 98\degree [/tex]
[tex] \because m\angle L =m\angle N[/tex]
(Opposite angles of a parallelogram)
[tex] \therefore m\angle L =98\degree [/tex]
Answer:
1 no the quadilateral is parallelogram
2 no .82+82+3x-1+3x-1=360
162+6x=360
6x=198
x=198/6
x=33
3 no angle L =3x-1(opposite angles of a parallelogram are equal)

Question: If 2cm represents 75 miles on a scale drawing. How long would a line segment be that represents 50 miles?
Answer:
1.33cm
Step-by-step explanation:
if 2cm is representing 75 miles, that means that .66 (repeating) is representative of 25 miles. This is because .66 (repeating) times 3 is equal to 2, and 25 times 3 is equal to 75. The reason 1.33cm would be equal to 50 miles is because if 25 miles is equal to .66, and 50/25 = 2, then you would have 2x.66 (repeating), to get 1.33.

So far Monica has read 5/6 of book she has read the same number of pages each day for 5 days. What fraction of the book does Monica read each other ?
Answer:
Each day she has read 1/6 of the book.
Step-by-step explanation:
Monica has read 5/6 of book .
Each day she read the same number of pages for 5 days
Each day she read 5/6/5= 5/6*5= 1/6
Each day she has read 1/6 of the book.
So that in 5 days it makes
1/6+1/6+1/6+1/6+1/6= 5/6

A rectangle has a side length of 2x and a diagonal of 8x. What is the missing lenght?
Answer:
2x[tex]\sqrt{15}[/tex]
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{15}[/tex] · [tex]\sqrt{x^2}[/tex]
This can be simplified to be 2x[tex]\sqrt{15}[/tex]

Step-by-step explanation:
A stem-and-leaf plot is a detailed graphical presentation of quantitative data on special kind of table that promotes visualizing the individual numbers in the data with the number at the stem being the first digits of the numbers in the data set while the leaf represent the last digit of each number in the data set
Following the above rule, the data in the given stem-and-leaf plot are;
64, 67, 69, 79, 81, 81, 83, 83, 84, 86, 90, 91, 92, 95
Therefore, the set of data that could have been used to create the stem-and-leaf plot is the data set that has all the numbers in the given stem-and-leaf plot which is the data set;
64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92.
Which relationship is true for the triangle based on the Law of Sines?
Answer:
We know the angle given refers to the length of the opposite side.
Given angle = 82 and the opposite side = 34 so part of the relationship is
sin 82 / 34 = sin ( ) / ( )
We are also given one side = 27 and that side is opposite angle at C
so that part of the relationship is sin C / 27
sin 82 / 34 = sin C / 27
A true relationship based on the Law of Sines was found in the given triangle.
In the given triangle
∠A=82°
Length of side in front of ∠A = 34
Length of side in front of ∠C = 27
What is sine law?According to sine law, in a triangle, ABC, if the sides in front of ∠A, ∠B, ∠C are a, b, c respectively then
[tex]\frac{SinA}{a} =\frac{SinB}{b} =\frac{SinC}{c}[/tex]
According to the sine law, the sides in front of angle A and angle C are 34 and 27 respectively.
So, [tex]\frac{Sin82}{34} =\frac{SinC}{27}[/tex]
Hence, a true relationship based on the Law of Sines was found in the given triangle.

Data are collected about the amount of time, in minutes, each band member spends practicing. How does a single outlier change the lower and upper quartiles of the collected data?
Answer:
A single outlier does not affect the values of the quartiles.
Step-by-step explanation:
It is given that data are collected for each band member that spends time on practicing in minutes.
We know that the interquartile range is defined as [tex]$\text{the difference between the upper quartile,}$[/tex] [tex]Q_3[/tex] and the lower quartile, [tex]Q_1[/tex].
This interquartile range describes the middle i.e. the 50 percent of the values when it is ordered from the lowest to the highest or may be from the highest value to the lowest values.
Therefore, the IQR is considered to be a better measure of the spread then the range since the values are not affected by the outliers.
Therefore, we see that the single outlier does not affect the values of the quartiles, it does not change the lower quartile as well as the upper quartiles.

Step-by-step explanation:
So we know it is less than a right angle and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(not what we are looking for) , 120, is greater, and 180 is greater which leaves us to our answer 45.

Answer:
To find the left triangle we make the two right triangles equal 1 square, making the area of that 2x2 or 4
Then we take the uppermost triangle on the left and find the area of that which is 2x2 / 2 or 2. Then we find the right uppermost triangle which is 5x 2 /2 or 5. Then we take the rightmost triangle and find that 4x 4 /2 or 8. Then we add the square in the middle which is 3 x 4 or 12.
Add those area 4 + 2 + 5 + 8 + 12. You should get 31.

Consider this equation. Cos(0) = 8/9 if 0 is an angle in quadrant IV, what is the value of tan(0)? I
Answer:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{8}{9}[/tex]
Where θ is in QIV.
And we want to find the value of tan(θ).
Recall that cosine is the ratio of the adjacent side over the hypotenuse.
Therefore, the opposite side is:
[tex]o=\sqrt{9^2-8^2}=\sqrt{17}[/tex]
Next, in QIV, only cosine is positive: sine and tangent are both negative.
Tangent is the ratio of the opposite side to the adjacent. So:
[tex]\displaystyle \tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}[/tex]
Substitute. Tangent is negative in QIV. Hence:
[tex]\displaystyle \tan(\theta)=-\frac{\sqrt{17}}{8}[/tex]
