Answer:

The answer is 7800 seconds

Explanation:

1 hour = 60 mins

2 hours = 120 mins (60×2)

120 mins + 10 mins = 130 mins

130min = 130 × 60 = 7,800 seconds

Sooo... 2 hr 10 min = 7,800 seconds

<em>hope this helps :D</em>

Answer:

3.844\,*\,10^5

So a=3.844 and b=5

Explanation:

Scientific notation requests to write a number using powers of ten as a factor accompanying a real number (a) between 1 and smaller than 10 that contains the digits to exactly represent the original number. So in this case, the number 384,400 can be written as:

384,400=3.844 \,*\,100,000= 3.844 \,*\,10^5

with a=3.844, and "5" as the exponent of ten (so b=5)
