Gabriel has two jars of jelly beans, one with x beans and the other with y beans. Each jar has a lever. When a jar has at least 2 beans, pressing its lever will give Gabriel one bean from it and move one bean from it to the other jar (if there are 1 or 0 beans in the jar, then pressing the lever has no effect). Determine necessary and sufficient conditions on x and y, so that Gabriel can extract all but one of the jelly beans.

answer: 0.64

step-by-step explanation:

0.50 , 0.75

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
