I believe that because there are 180 degrees in a triangle, and ACB is a triangle, you can add up two of the angles and subtract that from 180. So
30+50=80 and 180-80=100, that mean the angle above angle 1 is 100. And since angle one and that angle 100 are vertical angles, angle 1 = 100
Answer:
11/4
Step-by-step explanation:
<em><u>Step 1: Simplify both sides of the equation.</u></em>
12x+3−1=35
12x+3+−1=35
(12x)+(3+−1)=35(Combine Like Terms)
12x+2=35
12x+2=35
<em><u>Step 2: Subtract 2 from both sides.</u></em>
12x+2−2=35−2
12x=33
<em><u>Step 3: Divide both sides by 12.</u></em>
12x / 12 = 33 / 12x =
11 / 4

Answer:
k = ½
Equation => 
Step-by-step explanation:
Constant of proportionality (k) = y/x
Using a point on the graph, (6, 3),
k = y/x = 3/6 = ½
k = ½
Equation of the line:
Plug in the value of k into
(slope-intercept form of equation for proportional relationship)
Thus:

Expected value = Sum of Probability * Cost of each ice cream.
Expected value
= 50%* $1.20 + 30%* $2.00 + 2<span>0%* $3.50
</span>
= 0.50* $1.20 + 0.30* $2.00 + 0.2<span>0* $3.50
</span>
= $1.90
Expected value of the cost of one ice cream = $1.90
