( 2.8 , 4.4 )
It’s been a long time since I’ve done this so this is the best I could do
The number of picture frames he can put on the wall is 178 picture frames.
The wall is rectangular and it is 9 feet tall and 11 feet wide. let covert to inches.
9 feet = 108 inches
11 feet = 132 inches
<h3 /><h3>What is area:</h3>
The area is the space occupied by 2 dimensional figure. Let's find the area of the wall. Therefore,
area = lw
area = 108 × 132 = 14256 inches²
Therefore, let's find the area of the each picture frame. The frame is 8 inches by 10 inches.
area = 8 × 10 = 80 inches²
The number of picture you can put on the wall can be computed as follows:
He can put 178 pictures on the wall.

Vbox-vspheres
vbox=, I assume we are dealing with l=w=h
so
v=lwh=12^3=1728
vsphere=(4/3)pir^3
r=3
vsphere=(4/3)pi3^3=4pi9=36pi
8 of them so
8 times 36pi=288pi or about 904.7786842338604526772412943845 cubic inches
vbox-sphere=1728-904.7786842338604526772412943845=823.2213157661395473227587056155
space filled by packing beads is about 823.22 cubic inches
beads percent is 823.2213157661395473227587056155/1728 times 100=47.64% filled by beads
C.) 3:5 = 12:20
It is this because you can divide them evenly into each other. 3*4 is 12 and if you do 5*4 it is 20. Boo yeah
