Answer:
Step-by-step explanation:
Answer:
The total cost C = $10 + $0.05·x
Step-by-step explanation:
The given parameters are
The cost of the cell phone plan per month = $20
The number of minutes of free calls that one can make in a month = 200 minutes
The cost of additional minutes of cell phone call = 5 cent
5 cents to a dollar = $0.05
The total number of minutes of calls made in a month = x
The time duration of a person's usage of the cell phone in a month > 200 minutes
The total cost C of a person's usage per month is given by;
C = $20 + $0.05 × (x - 200) = $20 + 0.05·x - $10
C = $10 + $0.05·x
Where x > 200.
The degree of the polynomial is 7
Answer:
First drawing - answer is: D: DG, FG and DE
Second drawing - answer is: π (pi)
Third drawing - answer is: 70° ( If you mean on measure of central angle which is corresponing to the arc CB)
Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )
Step-by-step explanation:
For the second drawing
arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π
For the third drawing
∠CAB is peripheral angle of the central angle ∠CFB.
∠CFB= 2·∠CAB= 2· 35° = 70°
Good luck!!!
