Answer:  6 or -6

hello,

Step-by-step explanation:

Let say n the number

\dfrac{2}{3} *n^2-7=17\\\Longrightarrow\ \dfrac{2}{3} *n^2=24\\\Longrightarrow\ n^2=\dfrac{3*24}{2}\\\Longrightarrow\ n^2=36\\\Longrightarrow\ (n-6)(n+6)=0\\\\n=6\ or\ n=-6\\

Triangle ABC is rotated 180 degrees around point B and then dilated to form triangle DBE as shown. Which postulate or theorem es
sleet_krkn [62]

Answer:

AAA Similarity

Step-by-step explanation:

Given:

Triangles ABC and DBE

Required

Which postulate shows ABC and DBE similarity

From the question, we understand that the following transformation were done on ABC

  1. Rotation
  2. Dilation

It should be noted that, when a triangle (e.g. triangle ABC) is rotated, the length of the sides and angle measurements remain unchanged.

However, when this triangle is dilated, the sides of the triangle change, but the angles remain unchanged.

Having said that,

When ABC is rotated and dilated to form DBE, we have:

\angle A = \angle D = a

\angle B = \angle B = b

\angle C = \angle E = c

<em>[See Attachment]</em>

<em>Hence, the postulate that answers this question is AAA (Angle-Angle-Angle).</em>

Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths
Mice21 [21]

Answer:

Nina is not correct because 393.5$ less then yesterday's ticket sales.

Step-by-step explanation:

To find total sales she he is not correct because

3 / 4 of 1440 = 1,080$ ticket sales from yesterday

and 295.25 - 33.50 = 261.75$

Therefore, ( 3 / 4 * 1440 ) + ( 295.25 - 33.50 ) = 1,341.75$ sale of today

Ticket from yesterday and today

1,080 - 1,341.75 = 393.5

393.5$ less then yesterday's ticket.
