A carousel has 30 cars. Determine the angle of rotation that maps #6 to car #19.
ivolga24 [154]

Answer:  The answer is 260°.


Step-by-step explanation: Given that a Carousel has 30 cars. We need to find the angle of rotation which maps car no. 6 to car no. 19.

Now, the Carousel will make a regular polygon with 30 sides and each car as a vertex.

So, angle of symmetry for the polygon is

\theta=\dfrac{360^\circ}{30}=20^\circ.

Number of sides from car 6 to car 19 = 19 - 6 = 13.

Therefore, the angle of rotation that maps car 6 to car 19 is given by

\alpha=13\times \theta=13\times 20^\circ=260^\circ.

Thus, the required angle of rotation is 260^\circ.

Answer:

A) Volume of Prism = 48 ft cubed

B) Volume of Pyramid = 16 ft cubed

C) 1/3

This equation is true for all rectangular prisms and rectangular pyramids with the same length, same width, and same height.

Step-by-step explanation:

1) find the volume of the prism

2) volume of a prism = Length x Width x Height

3) 4 x 2 x 6 = 48

4) find the volume of the pyramid

5) volume of a pyramid = Length x Width x Height divided by 3

6) 4 x 2 x 6 = 48 divided by 3 = 16

Hope this helps :)
