The answer is A, the economy was largely based on agriculture.
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.
1 month = 5.5cm long
2 month = 7cm long
So 2 months
Answer:
Refraction trust me I am in high school biology
Step-by-step explanation:
X2/y+x2/
x=6
y=-4
z=-2
6✖️2/-4➕6✖️2
6✖️2=12
This goes for both due to PEMDAS
Now it looks like this:
12/-4➕12
-4➕12= 8
Now it looks like this:
12/8
Since there was no z then -2 wouldn’t be needed
So your answer would be 12/8
Hope this helps! :3
