Answer:7
Step-by-step explanation: 10 +10 +x+x=34
20+2x= 34
-20 20
2x=14 x=7
H=80 ft
Distance from horizon
=sqrt(h/0.57) miles
=sqrt(80/0.57) miles
=11.85 miles.
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
Answer:
20
Step-by-step explanation:
10+10+10+10=40
40/2=20
