Anthony bought 5 metal balls. All together, the balls weighed 0.61 pounds. To the nearest hundredth of a pound, how much, on average, did each ball weigh?

0.01

Step-by-step explanation:

since 5 of the all together weighs 0.61 pounds. to find the weight of a single one, divide by 5.

0.61/5 = 0.0122 pounds

if you wanna round this to 100th it is 0.01 pounds

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
