Answer: 14
explanation: work the problem in the smallest parentheses first. 14. now work the longer parentheses. 14/7=2. now multiply it by 7. 2x7=14
960$
80 x 12=960
the 2 weeks means nothing
3/22 is the answer in simplest form
The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
