Answer:
3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
If the first pipe can fill the pool in 9 hours that means that in 1 hour it fills of the pool, we use the same logic for the second pipe and conclude that in 1 hour it feels up
of the pool. If both were to fill the pool together that means that in 1 hour they would fill...
of the pool in 1 hour.
Now to find how many hours it will take divide the pool by the speed with which it is getting filled.
hours
3.6 hours in other words is 3 hours and 36 minutes.
If two triangles are similar, it means that one is the scaled version of the other.
In similar triangles, correspondant angles are the same, and correspondant lengts are all in the same ratio . The ratio between the areas is
.
So, for example, if the scale ratio is , all sides of the new triangle are twice as long as the sides of the old one, and the area of the new one is
times the area of the old one.
Since in this case the two areas are equal, their ratio is . This implied that also
, which means that also correspondant sides are equal.
In other words, these two triangles are not only similar, but congruent. This means that, in particular, all correspondant sides have same length, so the longest side of ABC has a length of 25 as well.
