At which angle will the hexagon rotate onto itself?

The correct answer is: 60°  

Step-by-step explanation:

Rotational symmetry is a type of symmetry, in which an object returns back to its original shape after rotation at an angle of 360°/n about a fixed point.

A hexagon is a regular polygon that has six edges and vertices. It has six internal angles, 120° each.

Since there are 6 equal edges, therefore, the hexagon will rotate onto itself after every rotation at an angle of: 360°/n = 360°/6 = 60°

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
