Explanation:
It depends on the definition of "factor" that you use.
One dictionary defines "factor" to be ...
"a number or quantity that when multiplied with another produces a given number or expression"
In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.
___
Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.
Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.
Answer:
<u>274.6 inches</u> more snowfall Michigan received during the winter of 1978-79 than in 1930-31.
Step-by-step explanation:
Given:
The state of Michigan recorded an all time high snowfall of 355.9 inches during the winter of 1978-79.
Its lowest snowfall of 81.3 inches was recorded during the winter of 1930-31.
Now, to find how much more snowfall did Michigan received during the winter of 1978-79 than in 1930-31.
The snowfall in 1978-79 = 355.9 inches.
And, the snowfall in 1930-31 = 81.3 inches.
So, to get the how much more snowfall in 1978-79 than 1930-31 we subtract:
Snowfall in 1978-79 - Snowfall in 1930-31.
Therefore, 274.6 inches more snowfall Michigan received during the winter of 1978-79 than in 1930-31.
