Answer:1/25
Step-by-step explanation:
1/25 = (2/5)/p. This can be solved by cross-multiplying: p = 25(2/5) = 10. He can clean 10 pools in 25 hours.
IT IS THE THIRD ONE:
3+8.486
because I find it like that
A bag has 5 red marbles, 6 blue marbles and 4 black marbles
so total no. of marbles = 5 + 6 + 4 = 15
now probability of picking a black marble = 4/15
after replacement again probability of picking black marble is 4/15
it is given that black marble is picked two times
so probability of picking black marble two times or picking , replacing , and then picking is 4/15*4/15 = 16/225
I believe 1) 4:40 2) 4:40 3) 7:40 if you are trying to figure out the time shown on each of the clocks
1 kilometer = 1000 meters
3 kilometers would be 3000 meters
Divide total meters by number of parcels:
3000 / 10 = 300
The answer is 300 meters
