Step-by-step explanation:
Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make
of the total work. If the same analysis is applied Niko, in 1 minute, will make
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make
of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:

Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the lengths of the angles' opposite sides are <em>1-√3-2</em>.
If the long leg is 8, then the short one is 8/√3, or <em>8√3/3</em>.
Therefore, the hypotenuse, which is <em>double the short leg</em>, is 16√3/3.
