Ok Les asked a question in the shout bax, and I shouted back I pmed her the answer, but due to the outpouring of PMs (one actually)

I shall post the question, and answer.

Ally is putting up a border where the walls meet the ceiling of a room. She has a 20m roll of wallpaper border. Both room A and room B have ceiling areas of 24m^2. The roll of border is enough for one room, but not the other What could be the dimensions of the rooms?"


the room the border fits into is 4 x 6

the room it doesn't can be 2 x 12

24m^2 is the area, the way of figuring area is width x length

so 4 x 6 is 24 ^2

and the border is the circomfrance to 4 + 4 + 6 + 6 =20M enough border.

but if its 2x12 (also 24m^2) it's 2 + 2 +12 + 12 = 28m not enough border

I excel a grade 5 math

I'm still stuck in grade 2 when it comes to spelling :crying4:
 
put the metric measurements in order, starting with the shortest :lloyd:

.8m 880mm 9m 89cm 98mm



most of em were using a ruler so i can't replicate them here...this is a quickie calculator jobbie -

Julia jogs around a park with the following dimensions: 74m, 23m, 92m and 31m. How far did Julia jog if she jogged around the park three times?

got a good health test here too I might have failed :alienhuh:

1.)if 2 trains leave montreal going to vancouver on the same day same time, and assuming it's 2,000 km to vancouver one train goes for 8 hours a day at 140km/hour, and the other goes for 14 hours a day at 80km/hour, which will reach vancouver first, and in how long.

2.)same problem, except tehy are going 5,000kms away

The question - "What is the purpose of the nervous system in the body"

Zach's answer - "The purpose of the nervous system is so that you can feel stuff. The brain is part of the nervous system and controls your body. Without it you would be as dead of a doorknob. :lol2:


he only got 1/3 on that one :eek6:
 
The train going 140kmh will get there first on both trips. They both travel 1120 km per day, but since the train going 140 does that 1120 in 8 hours, it gets there first.

Make it interesting. The train that goes 140 kmh leaves the station each day at noon. The train that goes 80 kmh leaves the station each day at 6:00 am.

ok, math question..when you smoke a joint, you have a roach left over, it takes 7 roaches to make a new joint


you have 49 roaches how many joints can you make?

Depends, are you straight rerolling, or cleaning the roaches out and rerolling? Are you shredding up the paper to add the resin? These are important factors. Besides you're bound to get your clip out and smoke that big roach down to a nub while you're rolling the others, so I say 6.

8, you can roll 7 out of the 49, plus the roaches from 7 = 1 more joint
