Show the steps you use to solve the problem. estimate: 120divied by 3

40

Step-by-step explanation:

1. We can tell 120 is divisable by three.  A trick I like to use is adding all the individual numbers with that numbers and seeing if the sum is divisible by three.

EX: 1+2+0=3 so we know 120 is divisible by three

7+2=9 so we know 72 is divisable by three.

2. divide the number by ten in your head.  

120/10=12

3. 12/3=4

4. 4x10=40

5.120/3=40

answer: the answer is simply nothing.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
