Total cans on bottom 4 shelves = 29 x 4 = 116
total cans on top 3 shelves = 42 x 3 = 126
total cans = 116 + 126 = 242 cans

-------------------------------------------------------------

used cans = 56
remaining cans = 242 - 56 = 186 cans
number of cans in each shelf = 9
number of shelves = 186/9 = 20 and 6 cans remaining
remaining 6 cans will be displayed in another shelf

total shelves = 20+1 = 21

29 x 4 = 116
42 x 3 = 126
116+126=242

242-56=186
186 divided by 9 = 20.6
so 21 shelves needed

hope this helps

Question on the picture:

Answer:

$36\ feet$

Step-by-step explanation:

Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,

$(height):(shadow)$

As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,

$6:1.7$

It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).

$6:1.7=x:10.2$
