Eduardwww [97]

Answer:

The remaining child got a fraction of  \frac{1}{10}.

Step-by-step explanation:

Lets take the fraction of the money fourth child got is x

Addition of all these fractions should be equal to 1.

⇒\frac{1}{3} +\frac{1}{6} +\frac{2}{5} +x=1

⇒\frac{10+5+12+30x}{30} =1 (Taking a common denominator)

⇒\frac{27+30x}{30} =1

⇒27+30x=30

⇒30x=3

⇒x=0.1

Therefore,

The remaining child got a fraction of  \frac{1}{10}.

two triangles have side lengths of 3 inches, 4 inches, and 5 inches, is it possible to draw two different triangles that meet th
Alenkinab [10]

Answer:

It is impossible to draw two different triangles with these criteria.

Step-by-step explanation:

The 3,4,5 triangle is a Pythagorean triplet, but if it was said to be 6,8,10, then yes two different triangles can be made, same with any other multiple of a 3,4,5 right triangle. The 3,4,5 triangle is in its reduced form causing there to be no other triangles that can be made that still function as a triangle through the theorem of triangles where the hypotenuse has to be bigger than either side length.
