Roland and Sam wash dogs to make extra money. Roland can wash all of the dogs in 4 hours. Sam can wash all of the dogs in 3 hour
dimaraw [331]
To complete the 100% of (the job) washing, Roland needed 4 Hours & Sam, 3 hour,
Mind you 100% = 1
Find for each one the (job) achieved in 1 hour:

Roland achieved 1/4   & Sam 1/3 each one in 1 hour.

In one hours both will achieve 1/4+1/3 =7/12

So they will complete 7/12 (of the job) in 1 hour & for a time = t they will complete 100% (or 1) of the job, that is 1/t =7/12 & t=12/7 =1.71 hour

40 POINTSSSSSS&gt; RIGHT ANSWER ONLY!!!!. Will report if answer is faulty. PLEASE HELP MATHEMATICIANS!!!!!!!
Marat540 [252]
The probability of hitting the black circle is closer to 0 than it is to 1. because: find area of circle ~ 3.14*r^2
which is 3.14 because the radius squared is 1. so 1*3.14= 3.14
 and the area of the whiteness is 121.
subtract 3.14 from 121 and you get 117.86 
this answer is closer to a 0 probability than the white space. the white space is closer to a probability of 1.
