Answer:
The area of the pendant is <u>12 square centimeters</u>.
Step-by-step explanation:
<u><em>The question is incomplete, so the complete question is below:</em></u>
Giselle a pendant on her necklace that is the shape of a regular hexagon. On the pendant, there are lines for the center of each vertex that divided it into congruent triangles. Each triangle has an area of 2 square centimeters.
![What\ is\ the\ area\ of\ the\ pendant?](https://tex.z-dn.net/?f=What%5C%20is%5C%20the%5C%20area%5C%20of%5C%20the%5C%20pendant%3F)
Now, to get the area of pendant.
In the hexagonal pendant there are congruent triangles that are divided from the lines of the center of each vertex.
<u><em>Each triangle's area</em></u> = 2 square centimeters.
As, we see in the figure below there are six congruent triangles in the hexagonal pendant.
Hence, <u><em>the number of triangles</em></u> = 6.
So, to get the area of pendant we multiply each triangle's area by the number of triangles:
![2\ cm^2\times 6\\\\=12\ cm^2.](https://tex.z-dn.net/?f=2%5C%20cm%5E2%5Ctimes%206%5C%5C%5C%5C%3D12%5C%20cm%5E2.)
Therefore, the area of the pendant is 12 square centimeters.
Answer:
√1762
Step-by-step explanation:
Square root of 1762
How?
Well 41^2+9^2=c^2
1681+81=c^2
1762=c^2
c=√1762
What is 68 divided by 18...which gives you 3.8
Answer:
Amira used 4 balloons for each balloon animal.
Step-by-step explanation:
From the table, we can conclude that:
For 20 animals being sold by her, the leftover balloons were 180.
Then there is an increase in the number of animals being sold. She now sells 29 animals. So, the increase in animals being sold is given as:
29 - 20 = 9.
So, 9 more animals were sold. The balloons used for these 9 animals can be obtained by taking the difference of the leftover balloons for the two days.
The difference of the leftover balloons = 180 - 144 = 36.
So, 36 balloons were used for selling 9 more animals.
Similarly, there is an increase of another 9 animals when 38 animals were sold as 38 - 29 = 9. Also, the balloons used in this case is 36 only as the difference of the leftover balloons is 36.
144 - 108 = 36
Therefore, we conclude that for selling 9 balloon animals, Amira used 36 balloons.
Number of balloons used for 9 balloon animals = 36
∴ Number of balloons used for 1 balloon animal =
(Unitary method)
Thus, Amira used 4 balloons for each balloon animal.
