Answer:
Step-by-step explanation:
The total of all angles in the triangle is 180
You already know 2 values for the triangle, Angle A 25 as well as Angle C 90
Your formula is
180 - 90 -25
Answer:
There are 17.4 minutes of commercials are shown each hour.
Step-by-step explanation:
An hour has 60 minutes.
So in 3 hours, there are 3*60 = 180 minutes.
The commercials show 29% of the time.
So we have 0.29*180 = 52.2 minutes, in total, of commercial.
Per hour, we have 52.2/3 = 17.4 minutes of commercial.

Answer:
<h2>y = -2x + 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:

We have two points (1, -1) and (2, -3).
Substitute:

Put it and the coordinates of the point (1, -1) to the equation of a line:

<em>add 2 to both sides</em>

Finally:
