Suppose L litres are required.@ 40% it will contain 0.4L of the active ingredient.Then total volume of mixture = L + 100 litresand volume of active ingredient = 0.4L + 25 litresThe strength is (0.4L + 25)/(L + 100) = 30% = 0.3(0.4L + 25) = 0.3*(L + 100)0.4L + 25 = 0.3*L + 300.1L = 5L = 50 litres.

What is the difference between paid entry basic date and basic active service date?

Basic Active Service Date is when you came into the military and swore in. For some that is about a week prior to Basic Training, for others, who were in the Delayed Entry Program, that can be months before basic training. PEBD is what finance uses to determine credible time you are getting paid for. I have 12 years of Active Federal Service but I am getting paid for 16 since I got out and went National Guard for four years. But this is only for pay purposes. The four years will not count for retirement unless there was active time in there.

What is the formula to convert an active sentence to a passive sentence?

There's no formula, really. Just make sure the Subject (actor) is doing the Acting (verb). Watch out for verb forms of "to be"-- is, are, was, were, has, had, have, etc. If your sentence includes "by", it is likely passive voice. And passive sentences are longer than active sentences. You may need to substitute synonyms for some words. If you have leftover words when making an active sentence, they are likely unneeded. She was walking to the store. She walked to the store.
