Answer:

1.5 x 10^-4

Step-by-step explanation:

move the decimal 4 places to the right in order for the number to be in correct notation.  Then add your x 10 and negative exponent since you moved your decimal to the right and not the left. If you moved it to the left, it would be a positive exponent.

Ella bought 8 meters of ribbon for $10.
Zanzabum

Answer:

$0.03 per inch


Step-by-step explanation:


We need to convert 8 meters to inches first.

Unit ratio for meters to cm is:

\frac{1m}{100cm}

So 8 meters is 800 cm

Now,

we need to convert 800 cm to inches

Unit ratio for cm to inches is:

\frac{2.54cm}{1inch}

So, 800 cm is :

\frac{800}{2.54}=314.96inches


To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):

\frac{10}{314.96}=0.032


Rounded to nearest hundredth, $0.03 per inch
