In my opinion, I would say that it was a concave, because if you look up the word concave it is, "having an outline or surface that curves inward like the interior of a circle or sphere."
I hope this helps, and if you need any additional help as to what a concave is, please refer to the link.

Answer:
A 90
Step-by-step explanation:
Rounding off numbers to their nearest mentioned position
allows approximation from the number value itself.
In the number 63, 849

5.
</span>Rounding off to the nearest ones would mean the
value of 9 which is equal to 63, 859.00</span>
Since there are no decimal values the ones value stays the
same. Take note of the rounding off rules between number 0-4 and 5-9.
keeping in mind that any line parallel to MN will have the same exact slope as MN's.

Answer:
Change the sign
Step-by-step explanation:
Asumming you are talking about the keep change flip method for dividing fraction, you would 1) keep 3/1, 2) flip the / symbol into * and 3) flip the 2nd fraction
