How many commercials do you watch in one year? How does that number compare to the national average for your age?
Determine how many commercials are in a typical 30 minute or 60 minute
television show and how many hours each week you watch television.
Research the national data. Then answer the questions and explain your
answers.

Step-by-step explanation:Typical breakdown is 66-75% of a show is content (22 minutes of total content for a half hour; 42-45 minutes for an hour). In a typical 30 minute show on network TV, you'll usually get 3 breaks of about 2-3 minutes each. The numbers that have been mentioned are not for televised sports, which have more commercials.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
