Evas cell phone plan allows her to send up to 125 text messages per month. if she sent 90 texts so far, what percent of her monthly message limit has she used?

72%

Step-by-step explanation:

We know that the milit of text messages is 125, so this number is the 100%.

We can represent this as follows:

Text messages     Percentage

         125          ⇒        100%

and we want to know what porcentage is 90 text, also i will call this unknown porcentage x:

Text messages     Percentage

         125          ⇒        100%

          90          ⇒        x%

To solve this problem we use the rule of three: we multiply the cross quantities on the table (100% and 90) and divide that by the remaining amount (125):

x% = (100%)(90) / 125

x% = 9000% / 125

x% = 72%

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.
