find the value of X assume that segments that appear to be tangent are tangent 7.
Answers
The tangent are tangent 7 value of X is 15.
The value of X, we need to use the fact that segments that appear to be tangent are actually tangent. This means that the line that contains segment AB is tangent to the circle at point C, and the line that contains segment DC is tangent to the circle at point E.
We can use the properties of tangent lines and the circle to find the value of X. First, we know that the tangent to a circle at any point is perpendicular to the radius that passes through that point. This means that angle ACB is a right angle, and angle CED is a right angle as well.
Next, we can use the fact that angles in a circle that intercept the same arc are congruent. Since arc AB and arc DE are congruent (they are both half of the circle), angles ABD and EDC are also congruent
We know that angle ABD is equal to 3X, and angle EDC is equal to 7X - 60
\(3X = 7X - 60\)
Subtracting 3X from both sides gives:
\(-4X = -60\)
Dividing both sides by -4 gives:
\(X = 15\)

If spring A has a spring constant which is 8 times spring B's spring constant, what is the ratio of their periods? Which is the stiffer spring?
Answers
If spring A has a spring constant which is 8 times spring B's spring constant then the ratio of their periods is = 9K and \(\frac{9K}{8}\)
Spring stiffness is a characteristic that describes the relationship between load and deflection. If k is stiffness, P is load, and x is deflection, P = kx. The smaller the deflection at a constant load, the stiffer the spring, k.
Given that,
If spring A has a spring constant which is 8 times spring B's spring constant,
Let us assume,
A spring is cut into two parts of length La and Lb
Also given that La : Lb
La : Lb = 1 : 8
The total of spring constant is = 1 + 8 = 9
If the length of spring is L , then La
La = \(\frac{L}{9}\)
And length of B , Lb
Lb = \(\frac{8L}{9}\)
We know, for spring force , spring constant or stiffness of spring is inversely proportional to length of spring .
K ∝ 1 / L
If initial spring constant is k then,
kL= KaLa = KbLb
Then,
Ka = \(\frac{K}{\frac{1}{9} }\)
Ka = 9K
And Kb = \(\frac{K}{\frac{8}{9} }\)
Kb = \(\frac{9K}{8}\)
Hence, stiffness of A is given by, 9K
Stiffness of B is given by \(\frac{9K}{8}\)
Therefore,
If spring A has a spring constant which is 8 times spring B's spring constant then the ratio of their periods is = 9K and \(\frac{9K}{8}\)

It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away. During the return journey, it took him 15 hours. Assume the pack ice was drifting at a constant rate, and that Fred’s snowmobile was traveling at a constant speed relative to the pack ice. What was the speed of Fred’s snowmobile?
Answers
Using the relation between velocity, distance and time, it is found that the speed of Fred’s snowmobile was of 27 miles per hour.
What is the relation between velocity, distance and time?
Velocity is distance divided by time, hence:
\(v = \frac{d}{t}\)
It took Fred 12 hours to travel over pack ice from one town in the arctic to another town 360 miles away, when the ice was drifting in the same direction, hence:
\(v_i + v_s = \frac{360}{12}\)
\(v_i + v_s = 30\)
\(v_i = 30 - v_s\)
In the return trip, with the ice in opposite direction he took 15 hours, hence:
\(v_s - v_i = \frac{360}{15}\)
\(v_s - v_i = 24\)
Since \(v_i = 30 - v_s\):
\(v_s - 30 + v_s = 24\)
\(2v_s = 54\)
\(v_s = 27\)
The speed of Fred’s snowmobile was of 27 miles per hour.

The sixth number of the arithmetic progression is 44
What is arithmetic progression?Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value.
For example 3, 8 , 13, 18, 23 is an arithmetic progression with common difference of 5
The nth term of a sequence is given as a1+(n-1)d
where a1 is the first number
Therefore
a5= 37
a4= 30
a2= 16
a3 = (30+16)÷2 = 46÷2= 23
therefore common difference = 23-16 = 7
a1 = 16-7= 9
therefore a6 = fifth number + common difference
a6= 37+7= 44

Answers
Answer:
150% = 132 cm, 25%= 22 cm, 100%= 88 cm
Given:
Height of Odalis = 132 cm
This height is 150%
Divided into 6 parts.
To find: Different percentages of Dallas's Height
Solution:
Dalia's Height = Odalis height * (100/150)
= 132 cm * (2/3)
= 88 cm.
150% of Dallas's Height is 132 cm.
25% of Dalia's Height = 1/4 * 88 = 22 cm
100% of Dalia's Height = 88 cm.
This can also be taken by parts.
6 parts = 150%
1 part = 150/6 = 25%
And 6 parts = 132 cm,
so, 1 part = 132/6 = 22cm.
so , 25% = 1 part= 22cm.
100% = 4 parts = 22*4 = 88 cm.
150% = 6 parts = 22*6 = 132 cm.
Hence, 150% = 132 cm
25%= 22 cm
100%= 88 cm

Your friend needs your help. His parents have told him that it is time for him to start paying for his own cell phone. After completing some research on the internet, you have narrowed down his options. Option 1 charges $0.30 for each cell phone call and $25 for unlimited text messaging. Option 2 charges a flat rate of $40.
Which plan is the best option?
Answers
Answer:
For less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.
Step-by-step explanation:
Option 1:
For n calls, the cost is given by:
\(C_{1}(n) = 25 + 0.3n\)
Option 2:
The cost is flat of 40, so \(C_{2}(n) = 40\)
Which plan is the best option?
Depends on the number of calls, as for a high number, \(C_1\) will be higher than \(C_2\). We have to find this number. So
\(C_{1}(n) > C_{2}(n)\)
\(25 + 0.3n > 40\)
\(0.3n > 15\)
\(n > \frac{15}{0.3}\)
\(n > 50\)
This means that for less than 50 calls, option 1 is the best, while for more than 50 calls, option 2 is the best.

Answer:
IQR= 3
Step-by-step explanation:
Hello!
The data represents the number of classes taught by each teacher at Broxin High School.
To calculate the IQR you have to do the following steps:
1) Arrange the data from least to greatest:
Raw data: 5, 7, 5, 1, 1, 9, 4, 5, 3, 4, 6
Arranged: 1, 1, 3, 4, 4, 5, 5, 5, 6, 7, 9
2) Calculate the 1st Quartile (Q₁):
The first quartile divides the bottom 25% of the data from the top 75%, to know which value of the data set corresponds to it you have to calculate its position:
PosQ₁= (n+1)/4= (11+1)/4= 3
This means that the 1st quartile corresponds to the 3rth observation:
1, 1, 3, 4, 4, 5, 5, 5, 6, 7, 9
Q₁= 3
3) Calculate the 3rd Quartile (Q₃)
The third quartile divides the bottom 75% of the data from the top 25%, as before, you have to calculate its position and then identify the value in the data set.
PosQ₃= (n+1)*(3/4)= (11+1)*(3/4)= 9
The third quartile corresponds to the 9th observation:
1, 1, 3, 4, 4, 5, 5, 5, 6, 7, 9
Q₃= 6
4) Interquartile range (IQR)
The IQR shows you the distance where the middle 50% of the data set is.
IQR= Q₃-Q₁= 6-3 = 3

15.
\(x = 4\) \(WX = 25\) \(XY = 17\) \(WY = 25\)
Step-by-step explanation:
Solving (14):
\(BC = BD\)
\(m<B = 13x - 35\)
\(m<C = 5x - 19\)
\(m<D = 2x + 14\)
First, we solve for x.
Since sides \(BC = BD\), then
\(m<C = m<D\)
This is so because the theorem of ASA (Angle-Side-Angle)
So, we have:
\(5x - 19 = 2x + 14\)
Collect Like Terms
\(5x - 2x = 19 + 14\)
\(3x = 33\)
Divide both sides by 3
\(x = 11\)
Solving for m<B, m<C and m<D.
We simply substitute 11 for x in their respective expressions.
\(m<B = 13x - 35\)
\(m<B = 13*11 - 35\)
\(m<B = 143 - 35\)
\(m<B = 108\)
\(m<C = 5x - 19\)
\(m<C= 5*11 - 19\)
\(m<C= 55 - 19\)
\(m<C= 36\)
\(m<D = 2x + 14\)
\(m<D = 2*11 + 14\)
\(m<D = 22 + 14\)
\(m<D = 36\)
Solving (15):
\(<X = <Y\)
\(WX = 9x - 11\)
\(XY = 4x + 1\)
\(WY = 7x - 3\)
First, we solve for x.
Since \(<X = <Y\), then
\(WX = WY\)
This is so because the theorem of SAS (Side-Angle-Side)
So, we have:
\(9x - 11 = 7x - 3\)
Collect Like Terms
\(9x - 7x = 11-3\)
\(2x = 8\)
Divide both sides by 2
\(x = 4\)
Solving for WX, WY and XY
We simply substitute 4 for x in their respective expressions.
\(WX = 9x - 11\)
\(WX = 9 * 4 - 11\)
\(WX = 36 - 11\)
\(WX = 25\)
\(XY = 4x + 1\)
\(XY = 4 * 4 + 1\)
\(XY = 16 + 1\)
\(XY = 17\)
\(WY = 7x - 3\)
\(WY = 7 * 4 - 3\)
\(WY = 28 - 3\)
\(WY = 25\)

Use cylindrical coordinates.
Find the volume of the solid that is enclosed by the cone

Answers
Answer: Find the answer in the attachment
Step-by-step explanation:
The volume constrained both by the cone and the sphere is \(21.905\pi\) cubic units.
The volume of a solid in cylindrical coordinates (\(V\)) can be determined by the following triple integral:
\(V = \iiint dz\,r\,dr\,d\theta\) (1)
The solid is constrained by the following equations in cylindrical coordinates:
Sphere
\(r^{2}+z^{2} = 32\) (2)
Cone
\(z = r\) (3)
The integration limits can be identified by using the following intervals:
\(z \in [0, +\sqrt{32-4^{2}}]\), \(r \in [0,4]\), \(\theta \in [0,2\pi]\)
And the triple integral has the following form:
\(V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\int\limits_{0}^{+\sqrt{32-r^{2}}} dz\,r\,dr\,d\theta\) (4)
Now we proceed to integrate the expression thrice:
\(V = \int\limits_{0}^{2\pi}\int\limits_{0}^{4}\sqrt{32-r^{2}}\,r\,dr\,d\theta = 10.952\int\limits_{0}^{2\pi}\,d\theta = 21.905\pi\)

y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First, we would find the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (6 - 3)/(2 + 1)
Slope (m) = 3/3
Slope (m) = 1.
At data point (-1, 3) and a slope of 1, an equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 3 = -1(x + 1)
y = -x + 4
For the quadratic equation, we have;
y = a(x - h)² + k
6 = a(-2 - 0)² + 2

Similarly, let Cooper's house be represented by the point (8.3, 7.4).The distance formula between the two points (2.8, 4.7) and (8.3, 7.4) is given by:distance = √[(8.3 - 2.8)² + (7.4 - 4.7)²]= √[5.5² + 2.7²]= √(30.25 + 7.29)= √37.54= 6.13 km (rounded to the nearest tenth)

I'm a bit rusty on SOE, so could someone help me with this?

The arc VQRST spans half the circle, so it measures 180 degrees. It's made up of the minor arcs VQ, QR, RS, and ST, so their measures all add up to 180 degrees.
\((y+7) + (x+11) + 3y + 65 = 180 \implies x + 4y = 97\)
The arc QRS is subtended by a right angle, so it measures 90 degrees. It's made up of arcs QR and RS, so
\((x+11) + 3y = 90 \implies x + 3y = 79\)
Solve for \(x,y\). Eliminating \(x\), we have
\((x+4y) - (x + 3y) = 97 - 79 \implies \boxed{y = 18}\)
Substituting this into either equation, we find
\(x + 4\cdot18 = 97 \implies \boxed{x=25}\)
The ratio of newcomers to returning students at the Midtown Adult
Learning Center is 3:7. Altogether there are 494 students at the center.
How many of them are newcomers?
Answers
Answer:
Step-by-step explanation:
Let's use algebra to solve the problem. Let's represent the number of newcomers as 3x, and the number of returning students as 7x, where x is some constant.
The total number of students is given as 494, so we can write:
3x + 7x = 494
Combining like terms, we get:
10x = 494
Dividing both sides by 10, we get:
x = 49.4
Since we can't have a fraction of a student, we need to round x to the nearest whole number. Since the ratio of newcomers to returning students is 3:7, we know that there are 3 parts of newcomers for every 10 parts of students. Therefore, the number of newcomers is:
3x = 3 * 49.4 = 148.2
Rounding to the nearest whole number, we get:
148
So there are 148 newcomers at the Midtown Adult Learning Center.
PLEASE HELP ON QUESTION ASAP !
hi ! I really need help understanding paragraph and I've also added a question about paragraph by me down below . Would like explanation in simple words.
If answers correct I'll rate you five stars a thanks and maybe even brainliest
Paragraph I needed help understanding:
If two or more cells are connected together side by side, the voltage across them is sum of the voltage of each cell. This is because both cells are pushing same way.
My Question about paragraph:
If the sum lets say was 4.5v would every individual cell be worth 4.5 as it says in question ' voltage across them is the sum of voltage of each cell ' or are they each a different value? And how would we be able to find value?.
Answers
If the sum of the voltage is 4.5V, it is possible that different cells have different voltages. For example, three cells with voltages 1V, 1.5V, and 2V could be connected together side by side to give a total voltage of 4.5V.
To find the voltage of each cell, we would need to know the voltage across each cell or the voltage of the other cells connected in the circuit. Then we could use the fact that the sum of the voltages across all cells in the circuit is equal to the total voltage of the circuit to solve for the voltage of each cell.

A boat travels 336 miles in 67
hours (with a constant speed).
How far can it travel in 58 hours
(with the same speed)?
Answers
Answer:
290.87 miles
Step-by-step explanation:
336 miles - 67 hours
x miles - 58 hours
Cross multiply
67x = 336 x 58
67x = 19488.
Divide both sides by 67
x = 19488/67
x = 290.87 miles
