Answer:

The width of the spacing between  each board is \frac{21}{56} inches.

Step-by-step explanation:

Given: Each board 9\frac{1}{4} inches.

Let's convert the mixed number 9\frac{1}{4} inches to improper fraction.

9\frac{1}{4} = \frac{37}{4}

Total width of 15 boards = 15 . \frac{37}{4} = 138 \frac{3}{4} inches

Now we have to find the total space between the boards.

The total space = 144 - 138 \frac{3}{4}

The total space = 5 \frac{1}{4}

There 14 equal spaces between each board.

To find the width of spacing between each board, we need to divide 5 \frac{1}{4} by 14.

The width of spacing between each board = \frac{5\frac{1}{4} }{14}

Now we can convert the mixed number to improper and multiply with the reciprocal of 14.

The reciprocal of 14 is \frac{1}{14}

= \frac{21}{4} . \frac{1}{14} = \frac{21}{56}

Therefore, the width of the spacing between  each board is \frac{21}{56} inches.

Rainbow [258]

To find out if the triangle is a right triangle, we must check if the following equation is true:

(15)^2+(20)^2=(25)^2^{}^{}^{}

on the left side, we have:

(15)^2+(20)^2=225+400=625^{}

and on the right side, we have:

(25)^2=625

since on both sides we get 625, we have that the brace forms a right triangle.
