Answer:
WU = (14√13)/13 ≈ 6.6564
Step-by-step explanation:
Call the incenter of ∆KWU point A. Call the center of circle ω2 point B.
Then ∠KWA has half the measure of arc WA. ∠AWU is congruent to ∠KWA, so also has half the arc measure. That is, ∠KWU has the same measure as arc WA and ∠KBW.
KB is a perpendicular bisector of chord WU, so ∆KWB is a right triangle, of which WU is twice the altitude to base KB.
The length of KB can be found several ways. One of them is to use the Pythagorean theorem:
KB² = KW² +WB² = 4² +6² = 52
KB = √52 = 2√13
The area of triangle KWB is ...
area ∆KWB = (1/2)KW·WB = (1/2)(4)(6) = 12 . . . . square units
Using KB as the base in the area calculation, we have ...
area ∆KWB = (1/2)(KB)(WU/2)
12 = KB·WU/4
WU = 48/KB = 48/(2√13) = 24/√13
WU = (24√13)/13 ≈ 6.6564
Answer:
Flip the second number
Step-by-step explanation:
To divide by a fraction, you simply flip it over and multiply
Take # 7 as an example:
5 /
becomes 5 X ![\frac{6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B1%7D)
Of course to make a whole number you put a 1 under it:
5 becomes ![\frac{5}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B1%7D)
Then you multiply straight across (top X top and bottom X Bottom)
Lastly, simplify as needed:
2 / ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Make the two a fraction and flip the fraction you are dividing with:
![\frac{2}{1} X \frac{3}{1} = \frac{6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1%7D%20X%20%5Cfrac%7B3%7D%7B1%7D%20%3D%20%5Cfrac%7B6%7D%7B1%7D)
which reduces to 6
To remember the steps use Keep it, Change it, Flip it.
Keep the first number, change from division to multiply, and flip the fraction you were going to divide by.
You need to first calculate the amount of lost money, which is 86-60.2=25.8 To find the discount, you need to put this over the initial price, or 86. This equals 0.3, which is 30 percent.
