inside the circle where there were 2 chords drawn. one chord the length was 7 (3+4) and the other with lenth 2x-4 (x-4+x) these 2 chords made 2 triangles (which i believe were similiar) was i to put the correspoding sides in proportion to find the value of x?

anyways can anyone fill me in on wat they might have gotten or how they procceded with the problem?

If you're American or even not, have you seen the "Price is Right" ?
They use the showcase-showdown "Big Wheel" numbering from 5 through 100 in 20 increments of 5.
You have one or two spins, and you choose after your first spin whether you want to spin again which adds to your total, or stay if you're in the lead or think you will win with your total.
Closest to 100 without going over wins.
If you tie someone, there is a one-spin spinoff, winner take all, repeating of course if a tie occurs again.
What are the values for each of the three contestant's first spins below which they should spin again and above which they should stay?

*A tie means they have a one-spin spin-off. (50-50) Repeated ties mean repeated one spin spin-offs until a winner is declared.

OK, here's the question:

3 men go into a restaurant for lunch. Their meals cost $10 each ($30 altogether). However, when the waiter adds up the bill he finds that it is only $25. So he gives $3 change to the men, but puts the remaining $2 in his pocket. (He's cheeky ;)

However - this means the men only paid $9 each for their meal (and $9 times 3 is $27) since they each got $1 change back.
Now the waiter has the $2, making that $29.

So where is the missing dollar?

Good luck working this one out - I first came across this logic question a year ago and it took Mum, Dad and my teacher to work it out!

The cost of producing a number of items x is given by
C = mx + b, in which b is the fixed cost and m is the variable cost (the cost ofproducing one more item).
If the fixed cost is $40 and the variable cost is $10, write the cost equation.
The revenue generated from the sale of x items is given by R = 50x. Graph the revenue equation on the same set of axes as the cost equation.
How many items must be produced for the revenue to equal the cost (the break-even point)?
