7. (5 Points) Suppose you are mixing Acid solutions in Chemistry lab. You need to have a solution of 60% acid. How can you obtain that by mixing a weak 20% solution with some
pure acid.
If you have 10 liters of the weak solution, how much of the strong stuff do you need to
add?
Solve either by the algebra method or explain how you can find the answer in the 'intuitive manner we
talked about in class.

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

42.4 6th grade students prefer hip hop

step-by-step explanation:

40 percent of 106 = 42.4

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
