 Question 5058: I have two problems that I have tried to answer but I need them checked to see if I did them correctly, and if not, what I did wrong. Your help will be very much appreciated. First problem: Write a complete solution to the following problem. If the degree measure of the smallest angle of a triangle is one-half of the degree measure of the second largest angle and one-third of the degree measure of the largest angle, then what is the degree measure of each angle? My answer: Smallest angle: x = 30 deg. Medium angle: 2x = 30*(2) deg. = 60 deg. Largest angle: 3x = 30*(3) deg. = 90 deg. Here's my second problem: Write a complete solution to the following problem. One side of a triangle is 1 foot longer than the shortest side, and the third side is twice as long as the shortest side. If the perimeter is less than 25 feet, then what is the range of the length of the shortest side? My answer: Shortest side: x feet Third side: 2x feet Other side: x+1 feet Perimeter: <25 feet 2x+x+1<25 3x+1<25 3x<25-1 3x<24 x<8 So, the range of the length of the shortest side is <8.

 Question 5149: why doesn't this work??? there's a bunch of us in denver, colorado that are perplexed!!! :) 3 fellows go into a hotel. The desk clerk tells them that it will be \$30 for the night, so each one pays \$10 and they head off to the room for the night. Shortly after, the manager reminds the desk clerk that they are running a special that night, and it's only \$25 for the room. The desk clerk pulls out five singles and gives them to the bell boy to return to the fellows. On the way up to the room, the bell boy realizes that it will be impossible to evenly split the \$5, so he takes \$2 for himself. Once he gets to the room, he explains to the fellows what happened, and returns the \$3, one for each fellow. This means that each fellow paid \$9 for the room. Now, add it back up. They each paid \$9. 9 times 3 is 27. The bell boy took \$2, that makes 29. Where is the extra dollar? any explanations??? THANKS! Click here to see answer by longjonsilver(2297)
