Help me with this question

Mathematics
1 answer:
MaRussiya [10]3 years ago

Answer:


Step-by-step explanation:


In kilograms, just move the decimal right before the first digit and multiply it by ten to the power of how many times you moved the decimal:

6.20 x 10^6

In grams, change 6,200,000 kg to g.  One kg is 1000 g, so divide  6,200,000 by 1000.  This would equal 6200 g.  Now, move the decimal right before the first digit and multiply it by ten to the power of how many times you moved the decimal:


6.20 x 10^3

Help WHERE DID THE 10 come from
kkurt [141]

Step-by-step explanation:

It came from nowhere.  It makes no sense to add up the balance numbers.  To illustrate, let's use a different example:

\left[\begin{array}{cc}Spend&Balance\\100&400\\100&300\\100&200\\100&100\\100&0\end{array}\right]

Adding up the money you spent, and you get $500.  Add up the balances, and you get $1000.  But why would you add the balances?  The 300 in the second line is included in the 400 in the first line.  You can't add them together.  You'd be counting the 300 twice.
