Answer:
Step-by-step explanation:
Adding the expressions in the numerator, we get:
6·10^(-5).
Then the given fraction appears like:
6·10^(-5)
-------------
3·10^7
First, we reduce 6/3, obtaining 2:
10^(-5)
2 -------------
10^(7)
Since the bases are the same, we can rewrite these exponentials with that base (10) and single exponent 12, which is the sum of 5 and 7 and is in the denominator:
2
---------
10^12
This matches the second possible answer choice.
Answer:
Megan paid $71,505 in total.
Step-by-step explanation:

Answer:
12 pieces
Step-by-step explanation:
Since on Thursday Glenn and Ben each ate an eight, then total they ate 2*1/8=2/8=¼
¼ of 24 pieces is equivalent to
¼*24=6 pieces
The number of pieces that remain would be 24-6=18 pieces
The one third of leftover ate rhe next day will be equivalent to
⅓ of 18
⅓*18=6 pieces
Remaining pieces next day will be 18-6=12 pieces
Therefore, only 12 pieces out of 24 original pieces remain the following day.
