Answer:
200 kg
Step-by-step explanation:
If w is the amount of water added, then the concentration of the solution is ...
salt/solute = 100(0.30)/(100 +w) = 0.10
30 = 10 +0.10w . . . . . simplify
20 = 0.10w . . . . . . . . subtract 10
20/0.10 = w = 200 . . . . divide by 0.10
200 kg of water must be added to dilute the solution to 10%.

Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
-6(3 + x) + 2(3x + 5) = 0
Step 2: Solve for <em>x</em>
<u>Distribute:</u> -18 - 6x + 6x + 10 = 0
<u>Combine like terms:</u> -8 ≠ 0
∴ No solution
Answer:
Step-by-step explanation:
<em><u>Given</u></em><em><u> </u></em><em><u>,</u></em>
Length of the tank = 27m
Width of the tank = 35m
Depth of the tank = 10m
<em><u>Therefore</u></em><em><u>, </u></em>
Volume of the tank = <em>Length</em><em> </em><em>×</em><em> </em><em>Width</em><em> </em><em>×</em><em> </em><em>Depth</em>
= 27m × 35m × 10m
