Answer:
Britain's goal with the Dominion of New England was to conglomerate all the governance of the colonies under one governor, a governor that would be able to properly enforce British laws. Before the Dominion was created, New England colonies were ruled under individual charters that allowed for self-government.
Step-by-step explanation:
% acid=[amount of acid / (amount of solution (acid + water))]*100
Data:
We have 5 gallons of a 20% acid solution:
amount of acid=20% of 5 gallons=(20/100)(5 gallons)=1 gallons
water amount=80% of 5 gallons=(80/100)(5 gallons)=4 gallons.
x=amount of pure acid (gallons).
(5+x)=amount of solution.
(1+x)=amount of acid in 50% solution
We have this equation:
50%=[(1+x) / (5+x)]*100%
(1+x)/(5+x)=50%/100%
(1+x)/(5+x)=1/2
2(1+x)=(5+x)
2+2x=5+x
2x-x=5-2
x=3
Answer: we need 3 gallons of pure acid.

Answer:
Step-by-step explanation:
Use the second equation to substitute for d in the first equation.
0.43t = 0.33t +8
Subtract 0.33t from both sides
0.10t = 8
Multiply by 10
t = 80 . . . . . . Michelle will catch Jen in 80 minutes
The distance traveled will be ...
d = 0.43t = 0.43×80 = 34.4 . . . . km
The girls will have traveled 34.4 km when they meet.
