A tank is 4/5 full of water.After drawing off 190 litres of water it is just 1/6 full.What is the capacity of the tank?
1 answer:
Let's convert the fractions to the same denominator
this means that when 190 liters, or 19/30 of the water was drawn off, there was 1/6 left.
let's create an equation and solve for x. we know that 190 is equal to 19/30 of the the tank. what about 1/30? we nee to divide each side by 19 to find out.
190/10 would be 19. this means that 1/30 of the tank is 19 liters.
to find the full tank, or 30/30 of the tank, multiply 19 by by 30, to get 570.
the full capacity of the tank is 570 liters
hope this helped!
p.s. can i have brainliest?

Answer:
- The limits are 908.6 cm^3 and 1417cm^3
- 1337.0cm^3 is in between the limits
Step-by-step explanation:
To determine the limit by taking into account the range rule of thumb, you use the fact that the limits are given by the mean plus and minus twice the standard deviation, that is:
(1)
: mean of brain volume = 1162.8 cm^3
σ: standard deviation = 127.1 cm^3
You replace the values of the parameters in the equation (1):
Limits = (1417 , 908.6)
The limits are 908.6 cm^3 and 1417cm^3
1337.0cm^3 is in between the limits calculated above.
