A student was assigned 40 math problems for homework. The student correctly answered 85% of the problems. How many homework problems did the student correctly answer ?

34 questions right

Turn 85% into a decimal so .85 then multiply by 40 to get 34

Step-by-step explanation:

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.

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
