There are 2015 marbles in a container. the marbles are numbered from 1 to
2015. marbles with equal digit sums have the same color and marbles with
different digit sums have different colors. how many different colors of marbles
are there in the container?

Step-by-step explanation:

I'm not certain but I believe it is 29

From 1 to 2015 the number with the highest digit sum is 1999. 1+9+9+9=28. Also digits can add up to all the numbers between 0 and 28 including 0 and 28, making 29 possible sums.

I don't fully understand the question but that is the best answer I can give from what I think they mean

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
