how much 45% acid solution should be mixed with a 30% acid solution to make 450 ml of a 40% acid solution?
FromTheMoon [43]
We do as follows:

let x = amount of 45% solution
    y = amount of 30% solution

overall balance =>    x + y = 450
acid balance     =>    .45x + .30y = .40(450)

Solving simultaneously, we will have:

x = 300 mL
y = 150 mL

This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.

Please help with the problem below! Thank you
Gwar [14]

Answer:

d \le -3

Step-by-step explanation:

The given inequality is;

\frac{d-3}{10} \ge \frac{2d+3}{5}+\frac{d+3}{3}

Clear the fraction by multiply through by 30;

3(d-3) \ge 6(2d+3)+10(d+3)

Expand;

3d-9\ge 12d+18+10d+30

Group like terms;

3d-12d-10d \ge 18+30+9

-19d \ge 57

Divide through by -19 and reverse the sign.

d \le -3
