I have the numbers 8,8,4,9. I somehow need to use all the numbers and get them to equal 24. I can add, multiply, divide, or subtract. I can only each number once. Need some help please! THANKS

THanks, but...73standard said:8+4-9x8=24

That is not the right answer.. the order of operations must be followed.

x,/,+.- with parentheses first.

8+4-9x8=8+4-(72)=(12)-72=-60

(8+4-9)x8 = 24.

3 guys enter a hotel and go to the reception. They ask the price for a room, and it's 30$ for the room. The three pay each 10$.

When they went to their room, the man behind the desk saw that the price for a room was only 25$, so he sent the boy who carries the luggage to the room with the 5$.

The boy didn't know how to divide the 5$ in three, so he gave each man 1$ back, and kept 2$ for himself.

Now, as each guy got 1$ back, they paid each 9$ for the room, so that makes 27 $, the boy kept 2$ for himself

Where is that one dollar ????

Lisa's team wins in 75% of his time. If the split was based on Time they would tie but based on distance she wins everytime.Mr B said:

A)What is the aceleration of the car during interval 1?Interval.Time.Description of motion.

1)10.0s.Accelerates from rest at a constaant rate to 24.0m/s

2)10.0s,travels at a constant speed from the end of interval 1

3))5.0s, slows at a constant rate to a velocity of 10m/s

4)5.0s, Travels at a constant speed from the end of interval 3

5)2.0s, Rapidly slows to a stop.

B)What is the acceleration of the car during interval 3?

My wife is a physics teacher. I picked a question (from the last test she gave out) and posted it here.ASurroca said:Oh, man, Tom, I remember getting questions like that years ago, but I completely forgot everything I learned. I think that was in calculus class. Can't remember anymore :lol:
