Jenny drew a figure in art class. Does it have rotational symmetry? If yes, what is the angle of rotation.

Andrews [41]

Answer:

60°

Step-by-step explanation:

Jenny drew a figure in art school and the figure is shown in the attached diagram.

The diagram is a regular hexagon and it has rotational symmetry.

Two of its sides is placed parallel to the x-axis.

Therefore, by rotating 60° the adjacent sides will become parallel to the x-axis and the figure remains the same and symmetric with respect to the coordinate axes. (Answer)

Who wants to help me on question 41. I don't understand what it means when it says "label a net".

Novosadov [1.4K]

A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.

1. Avital counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stay the same, how many more

Luba_88 [7]

X represents the number that would be added to the silver cars.

x/40= 4
X=40x4
x=160

Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4

Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points

Point (0, 2)

Point (3, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{2 + 3}{0 - 3}$
Simplify: $\displaystyle m = \frac{-5}{3}$
