Divided by 100 because u move the decimal over two places to the left
Divide each amount of napkins by the cost and that will get you the price for one napkin. You can use this to answer the other questions.
You take the base ten block and keep putting them in 8 groups then you will get the answer 98 hope I helped
Answer:
c
Step-by-step explanation:
The maximum distance is the <u>diameter of the circle</u>, which is of 44 units.
The equation of a circle of <u>radius r and center</u>
is given by:
![(x - x_0)^2 + (y - y_0)^2 = r^2](https://tex.z-dn.net/?f=%28x%20-%20x_0%29%5E2%20%2B%20%28y%20-%20y_0%29%5E2%20%3D%20r%5E2)
- The diameter is <u>twice the radius</u>, and is the <u>maximum distance</u> between two points inside a circle.
In this problem, the circular path is modeled by:
![x^2 + y^2 - 10x - 18y - 378 = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%20y%5E2%20-%2010x%20-%2018y%20-%20378%20%3D%200)
We complete the squares to place it in the standard format, thus:
![x^2 - 10x + y^2 - 18y = 378](https://tex.z-dn.net/?f=x%5E2%20-%2010x%20%2B%20y%5E2%20-%2018y%20%3D%20378)
![(x - 5)^2 + (y - 9)^2 = 378 + 25 + 81](https://tex.z-dn.net/?f=%28x%20-%205%29%5E2%20%2B%20%28y%20-%209%29%5E2%20%3D%20378%20%2B%2025%20%2B%2081)
![(x - 5)^2 + (y - 9)^2 = 484](https://tex.z-dn.net/?f=%28x%20-%205%29%5E2%20%2B%20%28y%20-%209%29%5E2%20%3D%20484)
Thus, the radius is:
![r^2 = 484 \rightarrow r = \sqrt{484} = 22](https://tex.z-dn.net/?f=r%5E2%20%3D%20484%20%5Crightarrow%20r%20%3D%20%5Csqrt%7B484%7D%20%3D%2022)
Then, the diameter is:
![d = 2r = 2(22) = 44](https://tex.z-dn.net/?f=d%20%3D%202r%20%3D%202%2822%29%20%3D%2044)
The maximum distance is the <u>diameter of the circle</u>, which is of 44 units.
