a stadium shaped like a hemisphere with a radius of 150 feet. last month the owners of the stadium paid $0.05 per cubic foot to
lesantik [10]

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

Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?
azamat

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 = x+20

And Jim doubles it, means 2*(x+20)

Jim gets 99.2 and as per us, he gets 2*(x+20)

So, making them equal

2(x+20)=99.2

2x+40=99.2

Subtracting 40 in both sides

2x+40-40=99.2-40

2x=59.2

x=29.6

It means the original number is 29.6.   :   Answer

Hope it will help :)

Prove that if a is equivalent to 5 mod (8) and b is equivalent to 3 mod (8), then 8 divides ab+1
olga nikolaevna [1]

Answer:

Explanation contains the proof.

Step-by-step explanation:

a \equiv 5 (mod 8) \text{ means there is integer } k \text{ such that } a-5=8k.

b \eqiv 3 (mod 8) \text{ means there is integer } m \text{ such that } b-3=8m.

We want to show that 8 \text{ divides } ab+1.  So we are asked to show that there exist integer n \text{ such that } 8n=ab+1 \text{ or 8n-1=ab

So what is ab?

a-5=8k \text{ gives us } a=8k+5.

b-5=8m \text{ gives us } b=8m+5.

So back to ab....

ab

=(8k+5)(8m+5)

=64km+40k+40m+25  (I use foil to get this)

Factoring out 8 gives us:

=8(8km+5k+5m)+25

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

=8(8km+5k+5m+3)+1

We have shown that there is integer n \text{ such that } ab=8n-1.

The integer I found that is n is 8km+5k+5m+3.

Therefore 8|(ab+1).
