Step-by-step explanation:

Scale factors deal multiplication. So, you would need to find a number to multiply by 6 to get 12. You can do this by doing 12 / 6.

Answer:

18.7 m/h

Step-by-step explanation:

I believe that is the correct answer because it shows the answer is going to be m/h (meter/hour) so then you would just divide the meters over the hours.

768.57 / 41.1 = 18.7 m/h

Rajan needs 1 liter of 15% hydrochloric acid solution for an experiment. He checks his storage cabinet, but he only has a 5-lite

yarga [219]

Answer:

Rajan must use 0.75 liters of 5% hydrochloric acid solution and 0.25 liters of 45% hydrochloric acid solution.

Step-by-step explanation:

Let us assume that, x liters of the 5% hydrochloric acid and y liters of the 45% hydrochloric acid solutions are combined.

As Rajan need total of 1 liter of solution, so

$x+y=1$

i.e $x=1-y$ --------------------1

As Rajan needs 5% hydrochloric acid and 45% hydrochloric acid to make a 1 liter batch of 15% hydrochloric acid, hence acid content of the mixture of two acids will be same as of the final one, so

$0.05x+0.45y=1\times 0.15$
