The polygon that when rotated at 180 degrees about it's center may not be carried onto itself is a quadrilateral. The reason being quadrilateral is not regular in the sense that different sides have different measures.
Answer:
7 more students need to sign up.
Step-by-step explanation:
if you subtract the number of students needed by the number of students you have, you get 7 (30-23)
(2) (2+5) = 14
2•2= 4
2•5= 10
4+10= 14
Answer: The Answer is in a fraction form
Step-by-step explanation:
9/73
20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.
Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours
So the answer is A.
