Give a button and a bookmark
to each student who visited the fair. the buttons came in
packages of 30. the bookmarks came in packages of 50.
the committee needed the same number of each left
over for another fair. the committee estimated that
400 students would visit the fair. how many
packages of buttons and packages of bookmarks
did they need?

15 packages of buttons

9 packages of bookmarks

Step-by-step explanation:

We need to find the least common multiple (LCM) of 30 and 50.

30 = 2×3×5

50 = 2×5²

LCM = 2×3×5²

LCM = 150

Now we need to find a multiple of LCM that is greater than 400.

3LCM = 450

The committee needs at least 450 of each, which means they need at least 15 packages of buttons and 9 packages of bookmarks.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

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.
