Answer:

31 yards of ribbon

Step-by-step explanation:

Of after purchasing the ribbon in bulk she has $21.28 left from her initial $25 it would mean that she spent $3.72 in total.

25 - 21.28 = 3.72

So in spending $3.72 on ribbons we can find how much yards she bought by seeing how many times 12 cents can go into the $3.72 (the amount of money she spent).

0.12 \sqrt{3.72}  = 31

I am confused please help

Answer:

3 tiles will not fit together.

Step-by-step explanation:

Measure of an Interior angle of a polygon = \frac{(n-2)\times 180}{n}

Here, n = number of sides of the polygon

Therefore, measure of the interior angles of a regular hexagon,

A = \frac{(6-2)\times 180}{6}

A = 120°

Similarly, interior angle of the regular pentagon,

B = \frac{(5-2)\times 180}{5}

B = 108°

Now m∠A + m∠B + m∠C = 360°

m∠C = 360° - (120° + 108°)

        = 132°

To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.

D = \frac{(8-2)\times 180}{8}

D = 135°

m∠C ≠ m∠D

Therefore, 3 tiles will not fit together.
