9 inches per year

Step-by-step explanation:

We are told that in a 3/12 year period, the amount of snowfall was 27/12. Therefore, we can find the amount of snowfall in one year by using the following proportion:

where 12/12 represents one year, and x the amount of snowfall in one year. Solving for x, we find

So, the average yearly snowfall is 9 inches per year.

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

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
