Question 341413: Hi,
I am currently tutoring H.S. Math and I'm horrible at Math! Do you have a good book (text book or otherwise) that you could recommend, when teaching H.S. Math?
Also, I'm stuck on this question....
At Southport College, walkways currently run between buidlings as follows: from Hammond to Fields, and from fields to Watson (as shown in the diagram below). However, students walking from Hammond to Watson routinely cut across the lawn.
And then there is a picture of a right triangle: the base is 20 m, the other side is 48 m and then the third side is the proposed walkway, which you have to figure out.
Haniya, who supervises maintence, plans to propose a direct walkway from Hammon to Watson. In her report, what length, in meters, should she indicate for the propsed walkway?
the answers are:
1) 50
2) 52
3) 56
4) 58
5) 68
The answer is 2) 52.
How do I do this problem? Step by Step....
Thank you!

Question 355604: A barker comes up with a new carnival game. A player will draw 1 card out of a full 52 card deck. If the player draws an Ace, they win $10. If they draw a face card (king, queen, jack) they win $1.00. Drawing any other card from the deck and they win nothing. How much do they have to charge to play the game to make it fair?
I did this: (4/52 *$10)+(12/52 * $1.00) + (16/52 * $0)= .77+.23= $1.00 is that right?
