Answer How much of a 20% acid solution should be blended with 30 liters of a 50% acid solution in order to achieve a 40% solution.... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That totals 18 liters of pure acid, resulting in a final mixture of 45 liters which contains 0.45 pure acid=18 liters.
Step-by-step explanation:
12 m^2/h to cm^2/min
12 m^2/h × 1 h/60 min = 0.2 m^2/min
0.2 m^2/min × 10000 cm^2/1 m^2 = 2000 cm^2/min
2000 cm^2/min
Answer:
x = 6
Step-by-step explanation:
The equation we need to solve is:
We can change it to exponential form to determine the answer. Below we illustrate the formula to convert log to exponential form:
Next, we convert the log into exponential:
Now we will solve for
