Answer:
8 Liters
Step-by-step explanation:
Percentage of Alcohol in water= 2L X 0 =0
Percentage of Alcohol to be added = xL X 0.9 =0.9x
- New Volume =(x+2) Liters
- Desired Concentration = 0.72%
Therefore:
0+0.9x=0.72(x+2)
0.9x=0.72x+1.44
Collect like terms
0.9x-0.72x=1.44
0.18x=1.44
Divide both sides by 1.44
x=8 Liters
Therefore, Shanice must add 8 Liters of 90% alcohol solution to create the desired mixture
Answer: 61
Step-by-step explanation:
First of all, a can be 11 and b can be 60 or other way around. Then, you use the formula to find the hypotenuse a2+b2=c2. Then, you substitute the given information: 11x11: 121, 60x 60: 3,600. Then add the answers: 121+3600=3721. Then do the square root of 3721 which is 61.
Point/slope form is:-
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line
In the above diagram the slope is -1 and one point on the line is (0, -2) so we have:-
y - (-2) = -1(x - 0)
y + 2 = -x
x + y + 2 = 0 is the answer
