30% of Number A is the same as 40% of Number B.
Goryan [66]

30% of number A means

\dfrac{30A}{100}=\dfrac{3A}{10}

similarly, 40% of number B means

\dfrac{40B}{100}=\dfrac{2B}{5}

These must be equal, so we have

\dfrac{3A}{10}=\dfrac{2B}{5}

Multiply both sides by 10 to get

3A=4B \iff A=\dfrac{4B}{3}

So, you can choose any number for A, and then you multiply it by 4/3 to get B. There are infinitely many solutions to this equation.

A square has a diagonal that is 26 feet long.<br> What is the perimeter of this square?
Bond [772]

answer:

52\sqrt{2}

step-by-step explanation:

  • we can use the 45-45-90 triangle theorem for this: x, x, x\sqrt{2}

this is because this is a square

  • squares have two sides of the same length, and the diagonal is different
  • the x's stand for the sides, whereas the x\sqrt{2} stands for the diagonal

x\sqrt{2} = 26

x = 13\sqrt{2}

  • now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4

13\sqrt{2} X 4 = 52\sqrt{2}
