How many gallons each of 25% alcohol and 5% alcohol should be mixed to obtain 20 gal of 10% alcohol

it would rotate about 180 degrees.

they charge the same amount at 20 minutes.

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

3+3+3+2*2*2+29*12 = 365
