Answer: 720ways, 24ways
Step-by-step explanation:
Given the seven letter words "SYSTEMS", if E is always occurring before M it means E and M will always be together therefore they letter 'EM' will be taken as an entity to five us 6letters i.e SYST(EM)S.
This can then be arranged in 6!ways
6! = 6×5×4×3×2×1 = 720ways
Similarly, if the E somewhere before the M and the three Ss grouped consecutively, this means E and M must always be together as well as the Ss to give (SSS)YT(EM).
This means that the letters in the bracket can be taken as an entity to give a total of 4 entities. This can them be arranged in 4! ways.
4! = 4×3×2×1
4! = 24ways
Involving the second and no higher power of an unknown quantity or variable.
Answer:
15:100:60 or simplify to 3:20:12
Step-by-step explanation:
15 is 15 percent of 100, 60 is 3/5 of 100. assume x is 100 because it makes the answer simpler. finally simplify by dividing everything by 5 so that you get the most simplified version of the equation because 3 is a pride umber and can no longer be divided unless in fraction or decimal form.
The third one is correct.
