There is a theorem that said that the ratio of lengths of chords at point  of intersection are the same.
I think the relationship would be X/W  = Y/Z

hope this helps

Answer with explanation:

Following theorems are used when there are segments that is chords are drawn inside the circle

1. Equal chords are equidistant from the center.

2. Perpendicular from the center to the chord bisects the chord.

3. Chord which are larger in length is nearer from the center.

⇒If these two segments are equal in length

 X +W=Z +Y

Otherwise, X+W > Z +Y

There is other relation possible between segment.

Join A, B,C and D.

In Δ AOB and ΔCOD

Angle in the same segment of a circle are equal.

→∠1=∠2

→∠3=∠4

→∠5=∠6------Vertically opposite angle

⇒ Δ AOB ≅ ΔCOD----[AAA similarity]

When triangles are similar their sides are proportional.

    \rightarrow \frac{OA}{OD}=\frac{OB}{OC}\\\\\rightarrow \frac{X}{Z}=\frac{Y}{W}

→X W=Z Y

Solve the following proportion for v. <br>8/5 = v/6 <br>Round your answer to the nearest tenth.​
bekas [8.4K]

Answer:

v=\frac{48}{5}=9\frac{3}{5} \\

Step-by-step explanation:

\frac{8}{5}=\frac{v}{6}

Swap sides:

\frac{v}{6}=\frac{8}{5}

Multiply to both sides by 6:

\frac{v}{6}\cdot6=\frac{8}{5}\cdot6

Group like terms:

\frac{1}{6}\cdot6v=\frac{8}{5}\cdot6

Simplify the fraction:

v=\frac{8}{5}\cdot6

Multiply the fractions

v=\frac{8\cdot6}{5}

Simplify the arithmetic:

v=\frac{48}{5}

what’s the answer and work for this??? SOMEONE PLEASEEEE TELLLLL MEEEE!!!!!
Cloud [144]

Answer:

ten scores in order: (Hint: These are in order)

81

81

  1. 82
  2. 84
  3. 85
  4. 86
  5. 89
  6. 93
  7. 94
  8. 95
  9. sum = 870
  10. mean = 870/10 = 87
  11. median 85.5 (5 above, 5 under)
  12. mode = 81 (there are two of them)

Hope this helped you solve the problem :)

P.S Bad at Math.

Step-by-step explanation:

Skills needed: Addition Multiplication Division Data Sets

When you get a big set of data there are all sorts of ways to mathematically describe the data. The term "average" is used a lot with data sets. Mean, median, and mode are all types of averages. Together with range, they help describe the data. Definitions: Mean - When people say "average" they usually are talking about the mean. You can figure out the mean by adding up all the numbers in the data and then dividing by the number of numbers. For example, if you have 12 numbers, you add them up and divide by 12. This would give you the mean of the data. Median - The median is the middle number of the data set. It is exactly like it sounds. To figure out the median you put all the numbers in order (highest to lowest or lowest to highest) and then pick the middle number. If there is an odd number of data points, then you will have just one middle number. If there is an even number of data points, then you need to pick the two middle numbers, add them together, and divide by two. That number will be your median. Mode - The mode is the number that appears the most. There are a few tricks to remember about mode: If there are two numbers that appear most often (and the same number of times) then the data has two modes. This is called bimodal. If there are more than 2 then the data would be called multi-modal. If all the numbers appear the same number of times, then the data set has no modes. They all start with the letter M, so it can be hard to remember which is which sometimes. Here are some tricks to help you remember: Mean - Mean is the average. It's also the meanest because it take the most math to figure it out. Median - Median is the middle. They both have a "d" in them. Mode - Mode is the most. They both start with "mo". Range - Range is the difference between the lowest number and the highest number. Take, for example, math test scores. Let's say your best score all year was a 100 and your worst was a 75. Then the rest of the scores don't matter for range. The range is 100-75=25. The range is 25.

Points A, B, and C are collinear. Find the value of x given AB = 3x, BC = 5x + 10. and AC = 74.​
Mars2501 [29]

Answer:

x = 8

Step-by-step explanation:

since it's a collinerar

or, AB+BC=AC

or, 3x+5x+10 = 74

or, 8x = 74-10

or, 8x = 64

or, x = 64/8

x = 8

Multiple choice please answer please
joja [24]

Answer:

A

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosA = \frac{adjacent}{hypotenuse} = \frac{AC}{AB} = \frac{2}{3} , thus

A = cos^{-1} (\frac{2}{3} ) ≈ 48° → A
