In the old aquarium, 3 tablespoons of salt were used for 20 gallons. That's a conversion ratio of
![\dfrac{3\,\rm tbsp}{20\,\rm{gal}}=0.15\,\dfrac{\rm tbsp}{\rm gal}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%5C%2C%5Crm%20tbsp%7D%7B20%5C%2C%5Crm%7Bgal%7D%7D%3D0.15%5C%2C%5Cdfrac%7B%5Crm%20tbsp%7D%7B%5Crm%20gal%7D)
That is, for every gallon of water in the aquarium, there was 0.15 tbsp of salt. So a 50 gallon aquarium, Ill should add
![(50\,\rm{gal})\left(0.15\,\dfrac{\rm tbsp}{\rm gal}\right)=7.5\,\rm{tbsp}](https://tex.z-dn.net/?f=%2850%5C%2C%5Crm%7Bgal%7D%29%5Cleft%280.15%5C%2C%5Cdfrac%7B%5Crm%20tbsp%7D%7B%5Crm%20gal%7D%5Cright%29%3D7.5%5C%2C%5Crm%7Btbsp%7D)
to maintain the salinity.
Well you have to subtract 14056 from 32713 and the answer will be 18657
Answer:
50 feet per second
Step-by-step explanation:
500 / 10 = 50
divide feet by seconds to find feet per second ratio
P=38
2x-5 I would set it to 38
2x-5=38 den add 5 to both sides
2x=43 den divide 2 to both sides
X=22 this might be wrong I might have fixed it with my Geo. if this isn't what ur doing please let me know
