Answer:

1200 L

Step-by-step explanation:

2/3 of the tank is removed, so 1/3 of the tank is left.  This is equal to 400 L.

1/3 V = 400 L

V = 1200 L

The volume of the tank is 1200 L.

Answer:

b = \sqrt{333}

Step-by-step explanation:

1. We can use the Pythagorean Theorem to find the missing side, b.

  • 14^2 + b^2 = 23^2

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (14*14)+b^2 =(23*23)
  • 196 + b^2 = 529

Step 2: Subtract 196 from both sides.

  • 196 + b^2 - 196 = 529 - 196
  • b^2 = 333

Step 3: Take square root of both sides.

  • \sqrt{b^2} = \sqrt{333}
  • b = \sqrt{333}

Step 4: Check if solution is correct.

  • 14^2 + \sqrt{333^2} = 23^2
  • (14*14)+(\sqrt{333} *\sqrt{333})=23*23
  • 196 + 333 = 529
  • 529 = 529

Therefore, b = \sqrt{333}.

mario62 [17]
It is false that deserts advance linearly, in easily mappable patterns.
Deserts don't really have a pattern when they are advancing - there are so many ways they can do this.
