Answer:
0.09 OR 9% is her tax
Step-by-step explanation:
Deborah has to pay 9% for tax. So is someone worked on her computer for two hours then she pays 9% on $120 worth of work. So her tax amount would be $10.800 and her total amount would be 10.8 +120 = $130.80.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Expected value of the bet = 
<h3>
P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) = </h3>
(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) = 
(64/132600) * 40 + (1 - 64/132600) *(-10) = 
64/3315 + (132536/132600) * (-10) = 
64/3315 - (132536/13260) = 
64/3315 - 33134/3315 = 
-33070/3315 =
-9.97586726998 = 
-$9.98, rounded to the nearest cent  
(i.e., the expected value of the bet is a loss of $9.98)

Answer: Angle C measures 132.5 degrees 
Step-by-step explanation: What we have here is an irregular polygon with six sides. Two sides have been identified as 90 and 130. And the other sides are yet unknown. We shall start by computing the total sum of the interior angles of the six sided polygon. 
The formulae for computing the interior angles of a polygon is given as (n - 2) x 180,
Where n stands for the number of sides of the polygon
Therefore in this diagram, sum of the interior angles equals
(6 - 2) x 180
= 4 x 180
= 720 degrees 
That means the addition of all the given angles equals 720. This can be expressed as follows;
90 + 130 + (x + 10) + x + x + x = 720
220 + x + 10 + 3x = 720
By collecting like terms we now have 
4x = 720 - 220 - 10
(Note that if a positive value crosses to the other side of an equation it becomes negative and vice versa)
4x = 490
Divide both sides of the equation by 4
x = 122.5
Therefore, since angle C is (x + 10)
C = 122.5 + 10
C = 132.5 degrees
