Answer:
1072.3
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*
= (2/3)*
= (2/3)**512
= 1072.3
Answer:
4/5
Step-by-step explanation:
Slope(m) = (y2-y1)/(x2-x1)
Pick two points on your graph that are closest to clear values. (By that I mean you shouldn't pick points that aren't obvious unless you have to.)
For instance, I see the points (-2,0) and (3,4) to be clear; so we don't have to approximate anything.
You could plug these in in a any order but I'm going to let Point 1=(-2,0) and Point 2=(3,4). So:
m=(4-0)/(3--2)=(4/5)
Slope=4/5
I dont know if those lines were suppose to be there, but i put 0.63 in simplest form = 63/100
Answer:
60%
Step-by-step explanation:
6 ÷ 10 = 0.6
Then, 0.6 can be made into a percentage by multiplying the decimal by 100 and then adding %.
0.6 x 100 = 60%

That's of course the 30/60/90 right triangle.
If you need to see the algebra, the acute angles in a right triangle are complementary, adding to 90 degrees:
x + 2x = 90
3x = 90
x = 30
