To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: The<span> regular octahedron with edges that are 2.1 inches.

 2. Therefore, you must apply the formula for calculate the volume of a octahedron, which is:

 V=(a^3</span>√2)/3

 3. Therefore, you have:

 V=((2.1 inches)^3√2)/3
 V=178.30 inches^3

Find Arc Measures of two diameters
svetoff [14.1K]

Answer:

m arc ACD =310

m arc AC = 130

Step-by-step explanation:

drawing the figure helps

if you do,  should get something like the figure below

filling in arc ad as 50 degrees tells you that the angle describing it is also 50 degrees; it's a central angle.

and we  know that 1/2 of a circle  is 180 degrees. so if you subtract 50 from 180 you'll get  130 which will be your measurement for arc AC (because it is a central angle and AC

+AD completes the 180 half.).

as well as that to get ACD, well 1st we know that arc AC is within arc ACD. that would mean that ACD has to be more than 130.

what you can do is subtract  50 from 360. the entire circle is 360, but  seeing as the arc is ACD (The rest of the circle excluding arc AD since we aren't looking for that measurement) we can just subtract.

subtracting 50 from 360 will give you 310

M+2 1/4=8 4/5 pls show your work . A) 6 3/1 B) 11 1/20 C) 6 11/20 D) 6 9/20
Neko [114]
Please include the instructions.  It appears that you want to find the value of m that makes m + 2 1/4 = 8 4/5, but you should state this explicitly.

Rewrite   m + 2 1/4 = 8 4/5   as   m + 2.25 = 8.80.
Subtr. 2.25 from both sides:        m             = 6.55   (answer)

This is also equal to 131/20 or 6 11/20.

Next time, would you please insert punctuation in your list of answers, to separate A from B, B from C, and so on.

Artist 52 [7]

The 40-year-old should have $76800 in capital. The 35-year-old should be saving $$10,320 for retirement.

<h3>How to solve for the amounts</h3>

The capital that a 40 year old has to have with an income of 32000 is

capital income at age 40 * income

= 2.4 * 32000

Capital = $76800

b. At 35 the savings income has to be

percentage of savings income * income

= 12% * $86000

= $10,320

c. There is no specified value for education earnings.
