how many gallons of 30% alcohol solution and 50% alcohol solution must be mixed to get 16 gallons of 35% alcohol solution? There needs to be (blank) gallons of 30% alcohol solution and (blank) gallons of 50% solution.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

thats not a system of equations, that is a solution

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
