Step-by-step explanation:
To factor a GCF, you just see the greatest common factor all the variables have in the equation.
1. <- here, for example, you can see that all the numbers in front of the variables can be divided by 3, so that is your first GCF.
<u>* you can only take out what you have, not what you don't have, btw.</u>
You can also see (by the powers) that you can take out x^3 because all the x's have at least 3 x's multiplied with each other.
And, you can take out only one y since there is at least one y in every set of variables.
Once you take out all of these GCF's, you divide each variable by them. This is because when you take them out, you're still going to be multiplying the whole set of variables by the GCF's, so <u>they should always equal their original form.</u>
I hope this step by step explanation for #1 is enough for all of the problems, if you need further help <em>please</em> feel free to comment! :)

The length of arc is 69.1 feet
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>
Where,
r is the radius
is the central angle in degrees
From given,
<em><u>Substituting the values we get,</u></em>
Thus the length of arc is 69.1 feet
Check the picture below.

Answer:$344
1/5 of 400 is 80 so if you subtract that it would be $320
1/50 of $400 is 8 so if you multiply that by 3,3/50 of $400 is(8*3)24 so $320+$24=$344
<u>Answer-</u>
It will take 665640 minutes for Strobe to travel one full rotation around its sun.
<u>Solution-</u>
Assuming all the time units i.e days and minutes are same as that of Earth, we know that a single day consists of 24 hours and each hour has 60 minutes in it.
We have been given that, Planet Strobe travels one full rotation around its sun in approximately 462.25 days.
Number of hours that is equivalent to 462.25 days is,
As we know the relationship between hours and minutes, 11094 hours is,
Therefore,planet Strobe will take 665640 minutes to travel one full rotation around its sun.
