What is the product of 16x48?
Elis [28]
768 because 6x8 = 48 the 8 drop Down to the answer and the 4 on top of 1 and multiply 1x8= 8+1 =9 so the 9 drop down to the answer. Now that is fake because you need to multiply 4x6 and 4x1 so 4x6 is 24 below the 8 add a 0 and go 1 move to the left and put 4 and 2 on top of 1 now 4x1 is 4+1 is 5 and put 5 on the left of 4 and the final step is add 98+540=768 so 768 is your real answer.

On his way to a local Hunting and Gathering Convention, Caveperson Stony Grok picks up a rock, drops it into a lake and watches
olganol [36]

Answer:

I guess that "Ura nok seblu" means that all rocks sink in water.

Step-by-step explanation:

A conjecture is an idea, opinion, theory or hypothesis, that is based on partial or incomplete information or evidence. Conjectures are generally speculations since there is not enough proof or evidence to support them.  

Even though Stony's theory didn't have a lot of evidence to support it, he was almost right. Most rocks sink in water, I guess that the only rock that doesn't is pumice. I might be wrong, but I don't know of any other rock that floats.
