How do you write 0.0024 in scientific notation?
0.000000025 = 2.5 × 10^-8To convert a number to scientific notation:write out the number starting with the first non-zero digit and continue until the last non-zero digit;put the decimal point after the first digit;count how many digits the decimal point needs to move to get back to where it was originally (if there was no decimal point as the number was a whole number it was "hiding" after the ones-digit, the last digit);if the decimal point need to move left make this count negative;write ×10 to the power of this count after the number written in step 2.→ 0.000000025 = 2.5 × 10^-8
What is the Speed of light in 2 significant figures?
The speed of light in vacuum is defined to be exactly 299,792,458 meters per second. Exact quantities have an infinite amount of significant digits. To reduce the expression to 2 significant digits, we take only the first two digits starting at the leftmost digit as accurate and round the quantity represented by the first 2 digits in their place value up if the third digit is greater than 5 or down if the third digit is less than 5. The reason for doing this is that we want the result to be the closest number of the two possible choices to the original value. For this reason, if the third digit is 5, consider the value of the fourth digit instead, as this will tell you whether rounding up or rounding down will give you the closest number. If the fourth digit and all the rest of the digits are 0, then both rounding up and rounding down are the same distance from the original number, and it is up to your local convention which one you choose to do. For this number, the first two digits, keeping their place value, gives us the number 290,000,000 meters per second. The third digit in the original number is 9, so we round 290,000,000 up to 300,000,000 meters per second. It is difficult to tell how many digits are significant in standard notation, so most publications use scientific notation. We would write it as 3.0x10^8 meters per second instead, where we explicitly write 2 significant digits including the significant 0 as the multiple of 10^8.

How many combinations are possible for a six-digit lock?
Assuming each "digit" actually has 10 different states, there are one million combinations possible in a six-digit combination lock. However, many combination lock designs actually have fewer than 10 different states per "digit", resulting in far fewer actual combinations on such locks.

How many 5 digit combos in 30 numbers?
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.
