If the radius goes through 1 rotation. The "angle" gone through is 360 degrees. So the method is to figure out circumference of the circle, multiply this by a fraction involving 120, and you are done.
Formula
Arc Length = (120/360) * 2 * pi * r Substitute values into this equation.
Givens
Central angle = 120
r = 9.5
Solution
Arc Length = (120/360) * 2 * 3.14 * 9.5
Arc Length = (0.333) * 2 * 3.14 * 9.5
Arc Length = 19.87 cm
Answer:
<em>The 15th term is 10.25</em>
Step-by-step explanation:
<u>Sequences</u>
The given sequence:
-0.25, 0.5, 1.25, 2, 2.75...
can be categorized as an arithmetic sequence. To better know, we try to find a common difference between successive terms:
0.5 - (-0.25) = 0.75
1.25 - 0.5 = 0.75
2 - 1.25 = 0.75
Once we are certain it's an arithmetic sequence, we find the general term by using the formula:
![a_n=a_1+(n-1)r](https://tex.z-dn.net/?f=a_n%3Da_1%2B%28n-1%29r)
Where n is the number of the term, a1 is the first term, and r is the common difference. We have already found that:
r=0.75
a1=-0.25
The 15th term (n=15) is:
![a_{15}=-0.25+(15-1)*0.75](https://tex.z-dn.net/?f=a_%7B15%7D%3D-0.25%2B%2815-1%29%2A0.75)
![a_{15}=-0.25+14*0.75](https://tex.z-dn.net/?f=a_%7B15%7D%3D-0.25%2B14%2A0.75)
![a_{15}=-0.25+10.5=10.25](https://tex.z-dn.net/?f=a_%7B15%7D%3D-0.25%2B10.5%3D10.25)
The 15th term is 10.25
Answer:
![\frac{4}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B25%7D)
Step-by-step explanation:
there are a total of 20 marbles and the chance that it is blue is 8/20 so multy that by itself and the answer is 4/25
