An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)
You wouldn't *really* need a protractor to complete your homework; you could guesstimate.
I hope this helps!
6/12=1/2
Therefore 6/12 is equal to 50/100 or 50%
Answer:
The Answer is 18

2 1/4 X 8= 18
Answer:
Step-by-step explanation:
We can see from the graph that 
can't be lesser than 
and extends unendlessly in the positive direction.
Answer:
Suppose the fraction of blue balls at any given state n is 
. At the start of the process we have: 
=1.
Now consider the situation after having drawn n times.
The current fraction of blue balls is , the number of blue balls is therefore 10.
We either draw a red ball, with probability 1−. and the number of red balls, blue balls stay the same (we swap red for red):
(red)=
or we draw a blue ball, with probability and we obtain 10−1 blue balls on a total of 10 balls, thus:
(blue) = (10− 1)/10
The total probability of (fraction of) blue balls after this n'th draw is therefore:
=(red)(1−)+(blue)
which can be simplified to:
=0.9
which leads to:
fn=0.9
At the end of the 10'th draw the fraction of blue balls is equal to:
= 
≈ 0.348678
