During the recycling drive, 1/5 of the material collected was bottles and 1/4 was paper. cardboard boxes made up 1/10 of the material. how much of the total do these three represent?

There would have been, 20 bottles collected, 25 pieces of paper collected, and 10 cardboard boxes. Theses three therefore show 55/100, of the total amount collected.

Step-by-step explanation:

So, to get this answer ^^, I had to find out how much each one of the materials was actually collected. So, for the bottles, I thought of how many 5's went into 100, which is 20, and then did 20 x by 1 (the fractions numerator), which gave me 20, therefore there was 20 bottles. Then, I did the same with the paper and the cardboard boxes. The paper was: 100 divided by 4 = 25, 25 x 1 is 25, and then the cardboard boxes was: 100 divided by 10 which is 10, 10 x 1 = 10.

Hope this helps! Xo

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
