Answer:
The height is 10in
Step-by-step explanation:
If you need to calculate the volume, you need to know the formula. The formula is length x width x height. You have the length and width, so you need the height. 2.5in x 15in x 10in = 375 in^3. You may ask why it is inches cubed instead of inches. It is inches cubed because you multiplied three inches together.
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:
Ted
Step-by-step explanation:
5t+4>19------------------ > 5t > (19-4)
5t > (19-4)----------------- > 5t >15---------------- > t >15/5------ > t >3
the solution of this inequality is (3, ∞)
the answer is D. 4 or more times
