Jose pose la question :
Mr. Appleberry brought in pumpkins for science class, one for each group.
The fist task wa to weigh the pumpkins, but the scales they had wouldn't register
any weight under 7 pounds, and it seemed that two ot three pumpkins were under
that weight. The class decided that they could weigh the pumpkins two at a time,
so they weighed each pumpkin with each of other pumpkins.
The weights registered on the scale were:
7 pounds
8 pounds
9 pounds
10 pounds
11 pounds
12 pounds
How many pumpkins were there, and how much did each weigh?

The angle between the hands on a clock |
2008-04-04 |
|
Kristin pose la question :
The question I need help with is : Bobo looked at the clock at 1:25. What was the precise measure of the angle formed by the hour and minute hands of the clock? Assume that each of the clock hands moves at a constant rate continuously around the face of the clock. Thus, in any given fractional part of an hour, each hand will move that same fractional part of an hour's worth of movement.
