Easiest way to find the arc is
2 * pi * r * ( the central angle (CA)/ 360)
20.pi* 2* r * central angle/ 360 = AB
2*r=24 CA/360=90/360=.25
pi*24*.25=pi * 6

So you should be able to use that formula on the rest :)

A large container has a maximum capacity of 64 ounces. The container is filled with 8 ounces less than its maximum capacity. Ans
son4ous [18]

Answer:

The container is filled to 87.5% of the maximum capacity.

Step-by-step explanation:

Given

Maximum capacity of container = m = 64 ounces

Filled capacity=> as it is 8 less than maximum capacity = 64-8 = 56 ounces

The container is 56 ounces full.

To find the percentage:

percentage = \frac{56}{64}*100\\= 0.875*100\\=87.5\%

Hence,

The container is filled to 87.5% of the maximum capacity.

Calculate the mean,median,and mode of the following set of data. Round to the nearest tenth 10,1,10,15,1,7,10,1,6,13
lions [1.4K]
Let's start with the mean. 

To find the mean of a data set, add all the numbers, then divide by the number of numbers there are. 

10 + 1 + 10 + 15 + 1 + 7 + 10 + 1 + 6 + 13 = 74
74/10 = 7.4

The mean is 7.4

Now for the median.

To find the median put all the numbers in order, then find the middle number.

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

The number in between 7 and 10 is 8.5
The median is 8.5

And finally, the mode.

To find the mode, find the number that appears the most. 

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

In this case, there are two modes. 1, and 10.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Find the other endpoint of the line segment with the given endpoint and midpoint: Endpoint - (1, 3) Midpoint - (0, 0)
Kobotan [32]

Answer:

The other endpoint of the line segment = (-1, -3)

Step-by-step explanation:

A segment has:

  • Endpoint: (1, 3)
  • Midpoint: (0, 0)

Let (x, y) be the other endpoint of the line segment

\frac{\left(1\:+\:x\right)}{2}=0

\mathrm{Multiply\:both\:sides\:by\:}2

\frac{2\left(1+x\right)}{2}=0\cdot \:2

1+x=0

x=-1

\frac{\left(3+y\right)}{2}=0

\mathrm{Multiply\:both\:sides\:by\:}2

\frac{2\left(3+y\right)}{2}=0\cdot \:2

3+y=0

y=-3

Therefore, the other endpoint of the line segment = (-1, -3)
