U never help me so why should i help u, thx for the points though
Answer:
m∠A and m∠B = 130°
m∠D = 50°
Step-by-step explanation:
If all angles equal 360° and angles A and B are equal then we know the A + D and B + C equal 180° then it's simple subtraction to figure out the degrees of all the angles
X: volume of the 20% sol'n to be used in the mixture
y: vol. of the 80% sol'n to be used in the mixture
Then x+y must equal 30 gallons.
.20x: amt. of pure fertizer in the 20% sol'n
.80x: amt of pure fert. in the 80% sol'n
.60(x+y) = amt of pure fert in the 60% sol'n
Then:
.20x + .80y = .60(x+y) = .60(30)
Since x+y must equal 30, y=30-x, and
.20(x) + .80(30-x) = 18
.20x + 24 - .80x = 18
6 = .60x
x = 10
Use 10 gallons of the 20% solution and 20 gallons of the 80% solution.
The result will be 30 gallons of a 60% solution.
Answer:
I don't know how this is math but...
The Gulf of Tonkin Resolution authorized President Lyndon Johnson to “take all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression” by the communist government of North Vietnam. Hope I helped! ☺
