The area of this figure would be 66 square centimeters.
Assume you need x liters 10% acid, y liters 80% acid
Then 10%x + 80%y = 65%*70, and x+y = 70
I get: x = 15, y = 55
The probability of a red marble is 25/250 or 1/10. The probability of a green marble is 50/250 or 1/5. The probability of a blue or orange marble is 175/250 or 7/10. Multiply the numerators and the denominators to get 7/500 probability (B)
