It take 23 minutes for 6 people to paint 6 walls. How many minutes does it take 9 people to paint 9 walls?

It would take 34.5 minuets for 9 people to paint 9 walls

Step-by-step explanation:

Divide 23 by 2 and you sound get 11.5

and 11.5 to 23 to get 34.5

The reason you must do it like this is because if they all do it at the same rate you need to know how long it would to for 3 people to do it so that you have a minimum point, then add the mid and min points to get the max point, 9 people.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
