You subtract the intial from the final. your answer is0.94grams
Step-by-step explanation:
This actually depends in different problem but the way I think your talking about is the easiest way.
Problem: 80% of 385
Step 1 You will be Multiplying
Step 2. Move the decimal to the left by 2 places.
Example: 385
x .80
----------
Step 3 do the problem
example: 385
x.80
-----------
308.0% is the percentage
make sure to drop the decimal but if there there nothing after it don't leave it in your final answers ( some teachers mark it wrong when it really it's not wrong just improper format)
The first one would be 6.
So, use the distance between two points formula:squareroot((x2-x1)^2+(y2-y1)^2)
squareroot((-7--4)^2+(8-7)^2)
squareroot((-3)^2+(1)^2)
squareroot((9+1)
squareroot(10)
squareroot 10 can be simplified to 3.2 units
