Find are of shaded region?

castortr0y [4]

Ignoring the triangle first off, it is just a parallelogram. We can find the area with:
$A_{P}=b*h=23.8 * 15=357 square ft.$ (see first diagram).

Next, we need to find the area of the triangle. Its a right angle triangle, so the area can be found by:
$A_{T} = \frac{1}{2} wl$
where w and l are the lengths of the two smaller sides. We have one, and the longer side (hypotenuse) so we can use Pythagoras' Theorem to find the other small side (see second diagram).
$b= \sqrt{ a^{2} - c^{2} } =\sqrt{ 23.8^{2} - 21^{2} }=11.2ft.$
Then find the area:
$A_{T} =0.5*21*11.2=117.6 square ft.$

Take the area of the triangle away from the area of the paralellogram:
$357-117.6=239.4 ft^{2}$

(a) We have three standard 6-sided dice, colored red, yellow, and green. In how many ways can we roll them to get a sum of 9? Th

Kisachek [45]

I believe that there are 23 different ways to get a total of 20. Then we need to find the number of ways to get each of the 23 different ways. For instance, one way is 6 6 1-1-1-1- 1-1-1-1: 101 / (21-8) = 45 (different ways to get this result) 10 different dice are rolled, giving the 101 in the numerator since the 6 is used twice, divide by 21, since the 1 is used 8 times, divide by 8! Etc., etc., etc. Final answers, add all these results together. I'm not sure about part B! I'm sorry!!!

Amelia makes necklaces using beads and wire. She starts with 6 feet of wire. How many necklaces can she make?

navik [9.2K]

If Amelia starts with 6 feet of wire, the amount of necklaces that she can make is 18.

<h3>What is the necklaces about?</h3>

Jewelry wire is known to be a kind of a wire that can be either a copper, brass, or others that are often used in jewelry making.

Note that Wire is seen today as a single unit, and it is also seen to be cylindrical, elongated part of drawn metal.

Using the table:

6 ÷ 1/3

= 6 x 3

= 18
