Ruben has two congruent wooden dowels. he cuts one dowel in two in order to have three pieces to make a triangle. explain why, despite having three sides, ruben will not be able to make a triangle with his three pieces?

Ruben will not be able to make a triangle with his three pieces of wooden dowels because The sum of any two sides of the triangle will not always be greater than the third side.

Recall the triangle theorem :

However, this is impossible as the sum will be equal to the length of the third side.

Hence, since the three sides do not conform to the triangle theorem, then Ruben will not be able to make a triangle with the three pieces.

Let us use the Pythagorean theorem in identifying what triangle can be formed.

Let us assume that the 2 wooden dowels each measure 8 inches. We cut off one wooden dowel into half, so it becomes 2 pcs of 4 inches each.

The 3 wooden dowels now measure, 4 inches, 4 inches, and 8 inches.  

The Pythagorean theorem states:  

a² + b² = c²

4² + 4² = 8²

16 + 16 = 64

34 ≠ 64

The measure of the cut wooden dowel must be longer than the uncut wooden dowel to create a triangle.  

I also tried this on a piece of paper, I cut each piece according to the assumed measure. No triangle can be formed under this activity.  

Step-by-step explanation:

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
