A chemist has three different acid solutions. The first acid solution contains 25% acid, the second contains 45% and the third contains 75%. He wants to use all three solutions to obtain a mixture of 156 liters containing 35% acid, using 2 times as much of the 75% solution as the 45% solution. How many liters of each solution should be used?

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
