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

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? Mathematics Answer Comment 1 Semmy [17] 1 year ago 5 0 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?

300 liters

Step-by-step explanation:

The capacity of the tank is unknown, so we call it x.

The tank starts 4/5 full, so the amount of water in the tank is 4/5 x.

190 liters of water are drawn from the tank, so now the tank has

4/5 x - 190 liters of water left.

We are told that the amount of water left is 1/6 of the capacity of the tank, so the tank now has 1/6 x of water.

4/5 x - 190 = 1/6 x

We now solve the equation for x, the capacity of the tank.

We need a common denominator for 5 and 6. We can use the LCD of 5 and 6 which is 30.

Multiply both sides of the equation by the LCD to eliminate the fractions.

30(4/5 x) - 30 * 190 = 30 * 1/6 x

30/5 * 4x - 5700 = 5x

6 * 4x - 5700 = 5x

24x - 5700 = 5x

Subtract 5x from both sides. Add 5700 to both sides.

19x = 5700

Divide both sides by 19.

x = 300

300 liters

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
