1 answer:

8 0

The correct answer is choice C) 136.2.

Why is it C)? Because 264.72 - 128.49 = 136.23 and then round it to nearest tenth and u get 136.2.

Nadia is investigating rotations about the center of regular polygons that carry the regular polygon onto itself. She claims tha

Answer:

$\theta_1 \ n\ \theta_2 = 120, 240$

Step-by-step explanation:

The question is incomplete, as the angles of rotation are not stated.

However, I will list the angles less than 360 degrees that will carry the hexagon and the nonagon onto itself

We have:

$Nonagon = 9\ sides$

$Hexagon = 6\ sides$

Divide 360 degrees by the number of sides in each angle, then find the multiples.

<u>Nonagon</u>

$\theta = \frac{360}{9} =40$

List the multiples of 40

$\theta_1 = 40, 80, 120, 160, 200, 240, 280, 320$

<u>Hexagon</u>

$\theta = \frac{360}{6} =60$

List the multiples of 60

$\theta_2 = 60, 120, 180, 240, 300$

List out the common angles

$\theta_1 = 40, 80, 120, 160, 200, 240, 280, 320$

$\theta_2 = 60, 120, 180, 240, 300$

$\theta_1 \ n\ \theta_2 = 120, 240$

This means that, only a rotation of $120, 240$ will lift both shapes onto themselves, when applied to both shapes.

The other angles will only work on one of the shapes, but not both at the same time.

Zoe is solving the equation 3x – 4 = –10 for x. She used the addition property of equality to isolate the variable term as shown

kherson [118]

3x-4 = -10

3x-4 +4 = -10 +4

3x = -6

then you can divide it :

x = -6 : 3

x= -2

A painter charges $35 per hour for labor plus $40 for a ladder rental when he paints a house. The customer provides the paint. T

zhenek [66]

the answer is not there. first you take 950.00 and back out (subtract) the 40 dollar fee for a ladder rental which leaves 910.00 then divide the 910 by 35/hr and you get 26 hrs.
