To prepare for a lab experiment, Ted is making a solution that uses two types of concentrations of HCI (hydrochloric acid): 80 ml of 50% HCI solution, and 120 ml of 20% HCI soulution. What is the HCI concentration of the mixed solution?

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

the square root of what number? if you add that, then someone will probably answer the question.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.
