spin [16.1K]

Answer:

\frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

Step-by-step explanation:

In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...

\frac{-90ft - (-15ft)}{40sec - 10sec} = rate of change

\frac{-75ft}{30sec} = rate of change

\frac{-2.5ft}{sec} = rate of change

Therefore, we can see that the rate of change of the diver is \frac{-75ft}{30sec} or simplified would be \frac{-2.5ft}{sec}

A guy walks into the store and steals $100 bill from the register without the owner’s knowledge. He comes back 5 minutes later a
Artemon [7]
The answer is $100
first the guy steals $100 from the owner. Therefore that $100 is a direct loss for the owner. 
the same guy comes and pays $100 for goods worth $70. and the balance is paid back to the guy. 
So the owner gets 100 and pays back 30 and gives goods worth 70. Therefore that transaction is cancelled as the amounts have been paid and no net effect with that transaction . the owner gets 70 for the goods he sold so that transaction wont lose his money. the fact that the guy paid for the bill with the money he stole isn't relevant here as the transaction has been completed
so the only loss for the owner is the $100 the guy stole at first 
answer is $100

2 1/2x -3/4 (2x+5)+3/8
OLEGan [10]
I am guessing this is an expression that needs to be simplify or factorise or both.
If the expression goes like this and I repeat :

2 1/2 x - 3/4 (2x+5) + 3/8
5x/2 - 3x/2 - 15/4 + 3/8
5x/2 - 6x/2 - 27/8
-x/2 - 27/8
-(4x + 27)/8 Answer:

Please comment me back if I got the question incorrect.
