The value of x in the triangle WXY is 27°
What is an equation?An equation shows how two or more numbers and variables are related to each other.
∠VWY + ∠XWY = 180° (sum of angle in straight line)
6x + ∠XWY = 180°
∠XWY = 180 - 6x
∠XYW + ∠ZYW = 180° (sum of angle in straight line)
∠XYW + 4x = 180°
∠XYW = 180 - 4x
∠XWY + ∠XYW + ∠YXW = 180° (angle in a triangle)
(180 - 6x) + (180 - 4x) + 90 = 180
450 - 10x = 180
10x = 270
x = 27°

What is the solution to 3(1-3x)=2(-4x+7)?
Answer:
x = -11
Step-by-step explanation:
3(1 - 3x) = 2(-4x + 7)
Distribute the 3.
(3 - 9x) = 2(-4x + 7)
Distribute the 2.
3 - 9x = -8x + 14
Add 8x to both sides.
3 - x = 14
Subtract 3 from both sides.
-x = 11
Multiply by -1.
x = -11.
Proof:
3(1 - 3x) = 2(-4x + 7)
3(1 - 3(-11)) = 2(-4(-11) + 7)
3(1 + 33) = 2(44 + 7)
3(34) = 2(51)

Is 8 15 17 a right triangle?
No, the sides of a right triangle do not include 8, 15, and 17. The sides of a right triangle must follow the Pythagorean theorem, so the sum of the squares of the two shorter sides must equal the square of the longest side. 8² + 15² does not equal 1
8² + 15² = 64 + 225 = 289
17² = 289
Therefore, 8, 15, and 17 are not the sides of a right triangle.
The Pythagorean theorem is an important mathematical concept used to determine if three numbers form the sides of a right triangle. This theorem states that the sum of the squares of the two shorter sides must equal the square of the longest side. In the case of 8, 15, and 17, 8² + 15² does not equal 17², so it is not a right triangle. To test this, we can calculate 8² + 15² = 289, and then 17² = 289. Since the two values are not equal, we can conclude that 8, 15, and 17 are not the sides of a right triangle.

Answer: In this exercise we have to calculate the values of the people who voted to expand the parking lot, so we have to:
Yes: parents will be 150 and not parents 40
No; parents will be 40 and not parents 30
As it is about sets, we have to use the data that were:

Suppose the number of adults who are not the parents and took the survey is .
As the total number of adults took the survey is 250 in which the number of parents took the survey is 180. Thus the number of adults who are not the parents and took the survey is,
Suppose the parents who does not thing that the park should be expanded is .
There is total 180 parents. As 150 of the adults with children thought the park should be expanded. Thus, the parents who does not thing that the park should be expanded is,
Form the 70 adults who are not parents things that park should be expanded is 40, hence the adults who are not parents does not thing the park should be expanded is (70-40) which is 30.

We have to find integers that satisfy 0 < a < 100.
a(a − 1)⁻¹ ≡ 4a⁻¹ (mod 20)
a ≡ 4a⁻¹(a − 1)(mod 20)
a² ≡ 4(a-1)(mod 20)

The value of πPhone stock has increased 9% each year for the past several years. In 2020, the stock was worth $75. What will the stock be worth in 7 years? What was the stock worth in 2016?
Answer:
2027 = $122.25
2016 = $48
Step-by-step explanation:
Find 1% of 75
75 / 100 = 0.75
multiply by 9
0.75 * 9 = 6.75
So that's $6.75 each year
Now, lets find our answers for 7 years.
6.75 * 7 = $47.25
75 + 47.25 = $122.25
The stock will be $122.25 in 2027
Now for 2016.
$6.75 * 4 = $27
$75 - $27 = $48
The stock was $48 in 2016
The following dotplot shows the centuries during which the 111111 castles whose ruins remain in Somerset, England were constructed. Each dot represents a different castle. According to the 1.5.IQR rule for outliers, how many high outliers are there in the data set?
The conclusion which we get after analyzing the data given is that there aren't outliers in the displayed data set.
We will calculate the interquartile range and us the rule 1.5 .
The formula to calculate interquartile range is to subtract the value of first quartile by the value of second quartile.
IQR = Q3 - Q1
Therefore, interquartile range becomes,
IQR = 17 - 13
IQR = 4
Now , we will apply rule 1.5 and for that we will multiply 4 by 1.5 first
4 * 1.5 = 6
and then,
17 + 6 = 23
on applying the rue we will get ,
13 - 6 = 7 .
This value means that there is no outlier in the displayed data set.

An aerospace engineer is designing a model of a portion of a new telescope, a cylinder with a cone cut-out as shown below. What is the total volume of the materials used to make the new telescope piece?
Answer:
See explanation
Step-by-step explanation:
The question is incomplete, as the required figure is not attached to the question.
From the question, we can deduce that the telescope is a composite figure made from a cone and a cylinder.
To get the volume of the materials used, you have to calculate the volume of the cone and that of the cylinder.
The sum of these volumes, is your answer.
Assume the following dimensions:
Cone
[tex]r = 5\\[/tex] --- radius
[tex]h = 7[/tex] --- height
Cylinder
[tex]r = 5\\[/tex] --- radius
[tex]h = 20[/tex] --- height
The volume of the cone is:
[tex]Volume = \frac{1}{3} \pi r^2h[/tex]
[tex]V_1= \frac{1}{3} \pi *5^2*7[/tex]
[tex]V_1= \frac{1}{3} \pi *25*7[/tex]
[tex]V_1= \frac{175}{3} \pi[/tex]
The volume of the cylinder is:
[tex]Volume = \pi r^2h[/tex]
[tex]V_2 = \pi * 5^2 * 20[/tex]
[tex]V_2 = \pi * 25* 20[/tex]
[tex]V_2 = 500\pi[/tex]
The total is:
[tex]Volume = V_1 + V_2[/tex]
[tex]Volume = \frac{175\pi}{3} + 500\pi[/tex]
Take LCM
[tex]Volume = \frac{175\pi+1500\pi}{3}[/tex]
[tex]Volume = \frac{1675\pi}{3}[/tex]

The number of students who went only to the water park is two times the number of students who did both. How many students did both?
60 students out of 210 in a school went both roller skating and water park.
What is algebraic equation ?
The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.
Have given ,
Total students = 210
Let x = The number of students who went only to the roller skating
and y = The number of students who went to the water park and roller skating
x + 4x + y = 210 ⇒ 5x + y = 210 ......(i)
x + y + 2y = 210 ⇒ x + 3y = 210 ⇒ x = 210 - 3y
Put the value of x in equation no. (i),
5(210 - 3y) + y = 210 ⇒ 1050 - 14y = 210 ⇒ 14y = 1050 - 210
14y = 840 ⇒ y = 60
Hence , 60 students out of 210 in a school went both roller skating and water park.
