The formula for volume of a hemisphere is: V = 2/3 * π * r³
Volume = 2/3 x 3.14 x 150^3
Volume = 7,065,000 cubic feet.
Multiply the cost per cubic foot by the volume:
7,065,000 x 0.05 = 353,250
The total cost was $353,250
Alright, lets get started.
Jim was thinking of a number.
Suppose the number Jim was thinking, is x.
Jim adds 20 to it means number will be = 
And Jim doubles it, means 
Jim gets 99.2 and as per us, he gets 
So, making them equal


Subtracting 40 in both sides



It means the original number is 29.6. : Answer

We want to show that
. So we are asked to show that there exist integer 
So what is
?

(I use foil to get this)
Factoring out 8 gives us:

Now I could have factored some 8's out of 25. There are actually three 8's in 25 with a remainder of 1.

We have shown that there is integer
.
The integer I found that is n is 8km+5k+5m+3.
Therefore
