erik [133]

Answer:

3.456E + 14= 3.456X10^{14

Step-by-step explanation:

The river discharges 4X10^6 cubic feet of water into the Pacific Ocean each second.

There are 86,400 seconds in one day.

Amount of water discharges each day

=4X10^6X86400\\=345600000000\\=3.456X10^{11

Since this differs from what you have, I will explain the scientific notation.

3.456E + 14 simply means 3.456X10^{14

The options are not well laid out but you can pick the appropriate option.

Anika [276]

Answer: 576.09

Step-by-step explanation:

First number = 5.19.

The second number was 10 times the first number which will be:

= 5.19 × 10

= 51.9

The third number was 10 times the second number. Thus will be:

= 51.9 × 10

= 519

The sum of the numbers will be:

= 1st number + 2nd number + 3rd number

= 5.19 + 51.9 + 519

= 576.09
