A box of cereal states that there are 90 calories in a 3/4 cup serving. What is the unit rate for calories per​ cup? How many calories are there in 4 cups of the​ cereal? please help me im really stuck it would be a huge help

What is the unit rate for calories per​ cup? 120 calories.

How many calories are there in 4 cups of the​ cereal?   480 calories

Step-by-step explanation:

if 3/4cup = 90 cal

then 3/4cup + 3/4cup + 3/4 cup+ 3/4cup = 3cups or 360cals ( 4 x 90cals)

and 360cals/ 3cups = 120 calories  

1cup = 120 calories so

  4cups x 120calories

4cups = 480 calories

Hope this helped :).

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
