Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6
Let's solve this system of 2 equations:
x + y =63
x + 0.1 y = 12.6
Solving it will give you:
x= 7 liters at 100%
y = 56 liters at 10%
The answer is: We are more aware of the positive form than the negative spaces. In which with every movement, the connection of form and space modify. A creator should possess every angle in mind in which the form is being created and the spaces adjoining the form. Space may comprise curls, the curves, the waves, the straight hair or any arrangement. In general, it is the space which is the area surrounding the form or area that the style occupies.
Answer: y = 2
Step-by-step explanation:
If you pay attention 2 goes into 8, 10, & 12 and it looks like they all have one C. So what do you think it is lol?(:
Answer:
h = - 105
Step-by-step explanation:
