Answer:
55:5 for the second one, 121:11 for the second one
Step-by-step explanation:
Answer: -4
Explanation: To find the rate of change, notice that the y values in the
table decrease by 4 each time and the x values increase by 1 each time.
Therefore, the rate of change, or the <em>change in y </em><em>/</em><em> change in x </em>is 4/-1 or -4.
15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to gallons, and the total volume increases to gallons.
To get a concentration of 8% in this diluted solution, we add gallons of water such that
Solve for .
To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
