Half of a dozen is 6. And 12+12 is 24 and 24+6 is 30. So Katoni bought 30 pencils.
Answer:
See explanation below
Step-by-step explanation:
Archimedes was able o obtain the actual volume of the supposedly gold made object by collecting the water displaced by the object as it was sunk on a bowl filled with water to the rim. Then knowing the volume displaced and therefore the volume of the object, he could find the object's density (mass over volume). The mass he could get just by weighting the object. and compare that with the density of any other object made of real gold (like for example a coin) and see if the quotient was the same. The density of both objects should be the same if they are made of the same material.
ANSWER:
B. $3.50
STEP BY STEP EXPLANATION:
We start out with buying the stock for $15.75 then sell it at $19.25. We need to find the difference.
Subtract $15.75 from $19.25
19.25 - 15.75 = 3.50
To check your work add $3.50 to $15.75
15.75 + 3.50 = 19.25
