In algebra, symbols are used to represent numbers. Example: 5x=20 or 4x=24
9.60 (.25) = 2.40
9.60 - 2.40 = 7.20
25% of $9.60 is $2.40, so the bottle would be $7.20
Answer: 196 m
Step-by-step explanation:
Since we know a circle has 360 degrees, the sector bounded by a 90 degree arc will be a quarter of circle (360/90 = 4). Then, to calculate the area of that sector, we can calculate the total area of the circle of radius 10, and then divide it by 4.
The area of a cirlce of radius r is:

Then, the area of the sector would be:
