Yes they can, this is because they area biological catalyst so the speed a reaction up without being used themselves. Hope this Helps Cat
no you can watch them over and over like a normal DVD
Explanation for the answer to how many three digit prime numbers can be formed using only odd prime digits and digits may be used more than once?
The odd prime digits are 3, 5, and 7. but the final digit of your three-digit prime number can't be 5. So there are only 18 combinations to check. You can list these numbers a…nd start going through them to see which are prime. The easiest test is divisibility by 3 (sum the digits) and that quickly eliminates 7 of them. You are left with: 337 353 373 533 553x 557 577 733 737x 757 773 Of these, only two are not prime. I marked them with an "x". I used a table of primes to find these and don't know an easier way.
How many three-digit numbers can be made with 0 1 2 and 3 and the same digit may be used more than once?
How many 4 digit number combination are there using 1 3 5 7 and you can use each number more than once?
A renewable resource.
How many ways are there to write a 3-digit positive integer using digits 1 3 5 7 and 9 if no digit is used more than once?
There are 5 digits, and if none can be repeated then the first digit can be chosen in 5 ways, the second can be chosen in 4 ways and the third in 3. 5 x 4 x 3 = 60.
5,040 Assuming that the combination uses ALL single digits from 0 to 9, then for the first digit you will be able to use all 10 numbers, for the second digit you will be able …to use 9, for the third digit 8 and for the last digit 7, giving a total number of combinations of 10 x 9 x 8 x 7 = 5,040 without the same number being used more than once in each combination.
How many 2-digit numbers can be formed from the digits 4 6 and 8 Assume no number can be used more than once?

An Epi-pen is a single use instrument. After use, it should be discarded in an appropriate container. If you continue to have the symptoms that made you use the Epi-pen in… the first place, you may give yourself another dose of the Epi-pen, provided you have another one in your possession. Once you use your Epi-pen, you should call for EMS and be transported to the hospital for evaluation of your condition and observation to ensure you do not have recurrence of your allergic reaction.
How many even 3-digit numbers can be formed from digits 1 3 5 and 7 if each digit can be used more than once?
If your only option is to assemble the digits into a single number, then the answer is 0, as you need at least one even digit to make an even number, and the digits provided a…re all odd ones. If on the other hand, you can use operators on them (e.g. 1 + 3 + 5 + 7), then you actually have quite a large number of possibilities. For example: 1 + 3 + 5 + 7 - 1 + 3 + 5 + 7 1 - 3 + 5 + 7 (1 + 3) / ( 7 - 5) 1 + √(7 + 5 - 3) 31 + 57 etc. etc. Alternatively, if you're not worried about them being even numbers, then the answer is 24.
Certain ones are designed for repeated use. The SPACE SHUTTLE was one example of such.

All the numbers from 500 to 599 EXCEPT 500, 511, 522, 533, 544, 550 - 559, 566, 577, 588 & 599. That is 100 less 19 ie 81. If you regard 505 as being a repetition then there a…re 9 less overall.
