When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:
3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.
We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86

Answer:
0.6666666667
Step-by-step explanation:
Mean: 4.6666666667
Median: 4
4.6666666667 - 4 = 0.6666666667
Answer:
V(t) = $40,000 + $3,300t
Step-by-step explanation:
The original capital, or the value V at t = 0, is $40,000.
The change in value per week is given by the difference between weekly income ($8,000) and expenses ($4,700).
Therefore, the value of the business (V) as a function of time 't', in weeks, is described by the following function:
