Answer:
She increased 80% the practise time
Step-by-step explanation:
The question is incomplete, the following is missing:
<em>by how much did she increase the time she practised each day?
</em>
From Monday to Wednesday she increased 90 - 50 = 40 minutes the practise time.

In this case, that is: 40/50*100 = 80%, where 50 minutes is taken as a reference.

mi
The area of a sector of a circle is:
A = π r² Ф/360
A = π (9)² 60/360
