It is difficult because prime numbers are numbers with no factors. There's not many. A lot of one digit numbers are prime and odd numbers but after 2, all of the even whole numbers are composite and some odds past 100 (and some before 100) are, also
What are the answer options?
A rotation of 270 would be equal to 630, 990, etc. Adding 360 degrees would result in the same rotation.
A rotation of 90 degrees counter-clockwise would also result in the same rotation, as would 90 plus any multiple of 360 if rotated counter-clockwise.

Step-by-step explanation:
9xy + 5y +
We know that
<span>8 machines in the factory could make all the bottles in 5 days
so
100%-----------> 5 days
1 day------------> 100%/5------> 20% with 8 machines
1 machine work at the rate-------> 20%/8-----> 2.5% per day
day 1---------> </span><span>4 machines are used to make the bottles-----> 4*2.5%---> 10%
</span>day 2--------> 4 machines are used to make the bottles-----> 4*2.5%---> 10%
day 3-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 4-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 5-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 6-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
<span>total work in 6 days=[10+10+20+20+20+20]------> 100%
the answer is
6 days
</span>
