3. Without computing, decide whether the value of each expression is much smaller than 1, close to 1, or much greater than 1.
a. 100 =
1000
b. 501 - 50
C. 4.7=5.2
d. 2: 7335

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

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
