Consider this option:
1. according to the first condition 45 min for 4 p. 5 walls, it means that: n*a*t=w, where n-numbers of people, a- ability of one person and w-numbers of walls.
4a*45=5, a=1/36 - ability for one person.
2. according the second condition for 6 people and 4 walls:
6*1/36*t=4, ⇒ t=24 minutes.
answer: 24 min.

If it is possible check the arithmetic part.

The diagram shows a triangle.<br> 490<br> 880<br> What is the value of v?<br> V =
Step2247 [10]

Answer:

43°

Step-by-step explanation:

The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...

49+88+x=180

Combine like terms:

137+x=180

Subtract the 137 on both sides:

x= 43

That's it the value of v is 43°.

How many sides are there on a convex polygon if the sum of the interior angles is 3240?
svp [43]

Answer:

20

Step-by-step explanation:

Let the number of sides be n

One exterior angle = 360/n

Exterior angle + interior angle = 180

Interior angle = 180 - Exterior angle

                      = 180 - 360/n

Sum of interior angle = n(180 - 360/n) = 3240

n(180 - 360/n) = 3240

180n - 360 = 3240

180n = 3240 - 360

          = 3600

n = 3600/180

   = 20
