Answer:

b = 70

Step-by-step explanation:

7+3/5b=7/10b

Subtract 3/5 b from each side

7+3/5b - 3/5 b=7/10b - 3/5 b

7 = 7/10 b - 3/5 b

We need to get a common denominator or 10 on the right hand side

7 = 7/10 b -3/5 *2/2 b

7 = 7/10b - 6/10 b

7 = 1/10 b

Multiply each side by 10

7*10 = 1/10 * 10 b

70 = b

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.
