Answer:

99 ways

Step-by-step explanation:

Let's say the the 11 courses are labeled a, b, c, d, ect. The possible chances of A bieng combined with another 9 appetisers is 9. Then B is combined with 9 appetisers. The C is combined with 9 appetisers and so on and so on. Meaning of there are 9 appetisers you times it by 11 main courses it means there will be 99 ways to make two course mean with one appetiser and one main course.

I am not 100% sure this is correct but this is what I think.

Step-by-step explanation:

Pi (Ratio of the Circumference of a Circle to Its Diameter) Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Answer:

Yes

Step-by-step explanation:

Yes they are because if you divide 18 by 3 you get six and if you divide 15 by 3 you get 5, so it simplifies to 6:3 which is the same as the ratio for rings

Find the coordinates of the point P at an angle of 45 degrees on a circle of radius 4.5. Round your answer to 3 decimal places.

Varvara68 [4.7K]

$\bf sin(\theta)=\cfrac{y}{r}
\qquad 

% cosine
cos(\theta)=\cfrac{x}{r}\quad 
\begin{cases}
r=radius=hypotenuse\\
x=adjacent\\
y=opposite\\
\theta=angle
\end{cases}\\
-----------------------------\\
thus
\\\\

\begin{cases}
r=4.5\\
\theta=45^o
\end{cases}\implies 
\begin{cases}
sin(\theta)=\cfrac{y}{r}\to sin(45^o)=\cfrac{y}{4.5}\to 4.5\cdot sin(45^o)=y
\\\\
cos(\theta)=\cfrac{x}{r}\to cos(45^o)=\cfrac{x}{4.5}\to 4.5\cdot cos(45^o)=x
\end{cases}
\\\\
P\ is \ at\quad (x,y)$

the angle is in degrees, thus, when taking either sine or cosine, make sure your calculator is in Degree mode
