Answer:
B
Step-by-step explanation:
Use the formula:
Radio= r, Height= h
V= 3.14xrx2h
r =25, h=31
V= 3.14 x 25 x 2 (31) =. 4867
V= 4867 cubic inches

Answer:
The answer is B: 468.50
Step-by-step explanation:
Let x = # of tickets sold in advance
Let y = # of tickets sold the day of
Cost of the tickets & total sales: 6x & 10y = 6828
You also know y = x + 206
Take the equation mentioned above y = x + 206 and sub it in anywhere the variable y is in the other equations so you'll have this:
6x + 10(x+206) = 6828
Now solve for x to get x = 298
To finish the problem, you must now find the number of y tickets sold.
Sub your x value that you found back into the equation y = x + 206 and you'll get y = 504.
So, 298 tickets were sold in advance and 504 tickets were sold the day of
Answer: 06.45
Explanation: For this problem, it is essential to know that there are 24 hours in a day. With that said, we take our starting time of 16.45 and since we want to know what time it is 14 ahead (addition), we add the two numbers together.
16.45 + 14 = 30.45
Since there are only 24 hours in a day, and we have exceeded that value, we subtract 24.
30.45 - 24 = 06.45
And that is the time in Brisbane.
Alternatively, you can count time in 12-hour format and convert 16.45 to 4.45 pm by subtracting 12.
Knowing your start time is 4.45pm simply add 14 to that (or change the pm to an and add 2 since 14-12=2).
You will again get 6.45am.
Cheers.
