In 1 meter, there are 10^9 nanometers, and in 1 second there are 10^{12} picoseconds, so we have

\dfrac{3.0\times10^8\text{ m}}{1\text{ s}}\cdot\dfrac{10^9\text{ nm}}{1\text{ m}}\cdot\dfrac{1\text{ s}}{10^{12}\text{ ps}}=3.0\times10^{8+9-12}=3.0\times10^5\dfrac{\text{nm}}{\text{ps}}

What is the 399,713 rounded to the place value of the third underlined digit of 399
maksim [4K]

The <em>correct answer</em> is:

400,000.

Explanation:

The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.

The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.

Total number of cards= (average number of cards)*(number of persons)

Total number of cards is

Fernando card +other two cards =33

Urgent will mark brainliest
Luda [366]

First, isolate the variable:

x>-33

The answers would be 25, 14, -25.

I am not sure if that is a more than sign or a more than or equals sign; if it is a more than sign the answers mentioned above are the only answers, but if it a more than or equals sign, the answers are 25, 14, -25, -33.

If it helped please consider giving be brainliest :)
