Mathematics

Answer In a poligon of n sides can be drawn n-3 diagonals from each vertex.

Explanation The triangle is the first closed polygon, which has three sides and it is not possible to draw any diagonal from a vertex. In a polygon with four sides it is already possible to draw a diagonal from each vertex to the opposite one. Then diagonals = n-3.

When Famke charges her phone, it gains 2 percentage points each minute. When Frmke uses her phone, it loses 5 percentage points
kkurt [141]
If t is the amount of time she used it, then it lost t*(5/min) percentage points; then she charged it for 2t, so it gained (2t)*(2/min) =t*(4/min) percentage points.
This means that above this time period, the phone lost t*(5/min)-t*(4/min) =t*(1/min) percentage points; because this loss is recognized to be 10 percentage points, this means t*(1/min) =10, so t=10 min.
This means that she used her phone for 10 minutes and charged it for 20 minutes.
