It takes 41 min for 9 people to paint 9 walls how long does it take for 14 people paint 14 walls

9p=9w=41

Therefore, it takes one person 41 minutes to paint one wall.

If the amount of people and walls painted are the same, the length of time to paint said walls will stay the same as well.

As long as the ratio between p and w, (people and walls painted) stays the same, the time it takes will remain constant at 41 minutes.

A:41 minutes

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
