Answer:
1 3/5 cups.
Step-by-step explanation:
That would be 4/5 * 2
= 8/5
= 1 3/5 cups.
You would expect an even number to be rolled 1/2 of the time as there are 3 evens and 3 odds
1/2 of 60 is 30
so you expect an even number to be rolled 30 times
Answer:
1010
Step-by-step explanation:
There are a whole class of questions that rely on the method to this one.
First add up what you know
1270 + 1150 + 870 + 1450 = 4740
Now add on the 5th month (which you don't know. Call it x)
4740 + x
Divide by 5
(4740 + x)/5 = 1150 and that is your equation
Solution
Multiply both sides by 5
5*(4740 + x) / 5 = 1150 * 5
4740 + x = 5750
Subtract 4740 from both sides
4740 - 4740 + x = 5750 - 4740
x = 1010
Which seems kind of low, but that's what the numbers come to.
The volume of any solid whose base is uniform is V = Ah. Since
the base is a sector of a circle, it’s area is defined by the equation A = θ (r^2)/2, where θ is in radians.
90 degrees in radians
is Pi/2. So the A = (PI) (r^2)/4
Therefore, V = [(PI) (r^2)/4]*h
