Answer:
(22÷7)×5×5=initial area
remaining area= 1/2(initial area)
=(11×25)÷7=39.28 square inches
Blue beads: 100/130, which reduces to 10/13.
Red beads: 20/130, which reduces to 2/13.
You're just taking the fraction of the certain color of beads compared with the total number of beads, which is 130.
The greatest common factor is 3x². The rest doesn't factor.
21x³y² -3x²y +75x⁴ = 3x²(7xy² -y +25x²)
3200 plus 1800 is 5000.
So find the percentage of 5000 1800 is.
So 36%
