Sales â Cost of Sales = Gross Profit â Operating Expenses = Operating Income. Using the operating income margin as an indicator--computed by simply dividing operating income by total sales--will allow you to measure managementâs efficiency in running the business. The higher the margin, the more efficient--this means that operating expenses are consciously guarded as sales grow.
Snakes 'hiss' - It sounds just like the sound humans make when they say the letter 'S' out loud. One of my favourite past-times is driving and exploring with my husband (and my dog). In WikiAnswers, I am constantly On the wallaby.
Can sharks hear a hum when something yummy is around? Sharks have keen hearing, a huge advantage in the ocean since sound travels both farther and faster in water. On top of that, sharks can pick up on very low-pitched noises known as infrasounds. Many oceanic sounds fall into this frequency range â a perfect example is the noise fish make when they're in trouble. Sharks hear this noise and know where they can track down some easy prey. Scientific studies have proven that when sharks pick up on infrasonic sounds â often their first clue about the location of prey â they usually swim over to the source in a hurry.
