Answer:
66 feet
Step-by-step explanation:
Mayra wants to place tiles on the edge of pool, i.e, on the circumference of the circular part
so the length required will be ,2πr
radius=21/2 feet=10.5feet
now req lenght = (2π10.5)=66 (feet)
Answer:
Approximately 19.4%
Step-by-step explanation:
Co. Dogs: 13
Co. Others: 54
13+54=Total Co.
=67.
Co. Dogs: 13/67.
App. 19.4% (For 13 Co.)
App. 1.49% (For 1 Co.)
Since this equation is already in standard form, there is no need to convert it. Standard form is Ax + By = C. In this equation, 7 = A, 3 = B, and 10 = C. From standard form, Ax + By = C equals negative A over B.
7x + 3y = 10
↓
![\displaystyle\ m= \frac{-7}{-3}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%5C%20m%3D%20%5Cfrac%7B-7%7D%7B-3%7D%20%20)
Then you'd simplify.
![\displaystyle\ m=\frac{7}{3}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%5C%20m%3D%5Cfrac%7B7%7D%7B3%7D%20%20)
The slope cannot be simplified any more, so this would be the final answer.

Hi!
To find the semmetry between the nonagon just do this:
360 / 9 = 40
The regular nonagon has rotational symmetry of 40 degrees!
