Question

A painting job can be completed by 4 painters in 23 days.

If 8 more painters join the team 5 days after starting work on the job, how many more days are required to complete the job?

A 24" x 24" square metal plate needs to be attached to a wooden board.

Nails are used all along the edges of the square such that there are 25 nails on each side of the square.

Each nail is at the same distance from the neighbouring nails.

How many nails are used?

Answer 1

shouldn't Question 1's answer be less days

and question 2 ...idk

Answer 2

96NAILS

Answer 3

With all those painters it would probably take forever, as they would stand around talking.

Nailing the plate would use 96 nails

Answer 4

I dunno about the first one but the second one sounds like a trick question.... 25 nails on each side... a square has 4 sides so you need 100

probably wrong but that's my guess... good luck x

Answer 5

6 more days are required

There are 96 nails

Answer 6

There are 96 nails on the square. It doesn't matter how big the square is. If there are 25 nails along each side that means 25 X 25 in one direction (i.e. up and down), so 50. But, you have to take back two nails from the count on either edge going the other direction (top/bottom) because they are already counted from the other sides. 100 - 4 = 96.

Answer 7

1. You would not need any more days, the job would be finished sooner.

2. Can you nail into metal? you would have to drill holes first for the 100 nails or form lines for the plate to sit on..

Answer 8
