The object is to get everything except for "h" on one side of the equation.
The equation says that everything on the right side is being multiplied by 1/2.
What do we have to multiply times 1/2 to get 1? The answer is 2.
So multiply both sides by 2 to get rid of the fraction.
2A = (a+b)h
Now we are multiplying h times (a+b) so to get rid of (a+b) we have to divide both sides by that term.
(a+b)/(a+b) is 1
So you are left with: 2A/(a+b) = h
Done!
Volume = pi x radius^2 x height
400=3.14 x 4^2xheight
400=50.24h
400/50.24= h
7.96 = height
Answer:
V = 270 cm³
Step-by-step explanation:
Remember your volume formula: V=<em>lwh</em>
So, plug in all your variables and multiply:
(6)(5)(9) = 270
And we have our final answer!
The ones where I had to dance. For me, I am not a big fan of dancing and we had to do the la cha cha as our warm ups everyday. It was so weird. I think I rather do 5 push-ups, 10 sit-ups and jumping jacks for a warm up instead. :V
Answer:
48 +72- 0= 120 that is my simplification
