A snowstorm lasted for three days. During the storm, 8 inches of snow fell on the first day, 6 inches of snow fell on the second day, and 9 inches of snow fell on the third day. Altogether, how many feet of snow fell during the three-day snowstorm? Write your answer as a mixed number. During the snow storm feet of snow fell. In mixed number

Step-by-step explanation:

Given

Snowfall on the first day is 8 inches

Snowfall on the second day is 6 inches

Snowfall on the third day is 9 inches

Also, 1 ft= 12 inches

Total snowfall is

Converting inches to feet

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the second option
