Answer:
28413.4 in (radius} = diameter divided by 2 = 47.7 divided by 2 =23.85
radius= 2
diameter
= 2
47.7
=23.85
<span>The video last for about 6.44 minutes. Rounded to the
nearest minutes
=> So let’s simplify the given equation
=> 6.44 minutes in where 6 = minutes, 44 = seconds.
Now, we have our minute’s value which is 6, let us start the rounding
=> 6.44, the number that follows the 6 is a decimal number which is 4.
4 is below 5, so we need to follow the rounding rule. This will round down.
=> 6 minutes
Therefore, the video lasts for about 6 minutes.

Answer:
C. -11,325
Step-by-step explanation:
- To know the answer, is convenient to replace some values of "n" in the sum
![\sum_{(n=1)}^{150}[-1-(n-1)]](https://tex.z-dn.net/?f=%5Csum_%7B%28n%3D1%29%7D%5E%7B150%7D%5B-1-%28n-1%29%5D)
.
- The result would appear after adding up every value of the expression when n=1,2,3.....,150.
- When n=1, the expression takes the value of (-1):
![[-1-(1-1)]= (-1)-0=-1](https://tex.z-dn.net/?f=%5B-1-%281-1%29%5D%3D%20%28-1%29-0%3D-1)
. - When n=2, the expression takes the value of (-2):
![[-1-(2-1)]=-1-1=-2](https://tex.z-dn.net/?f=%5B-1-%282-1%29%5D%3D-1-1%3D-2)
. - Following this way, for every n, we will obtain -n, then, the sum will be:
. This sum can actually be expressed as 
, which is the result of solving the initial expression of the sum 
. - Finally, the sum of n=-1 to n=-150 equals -11,325.
I would assume that he's using a 90° rotation.
