Answer:
Total amount paid = 20 + 15x
11 months
Step-by-step explanation:
Annual fee = $20
User charge per month = $15
Number of months = x
Total amount paid = 20 + 15x
Felix prepaid = $185
Total amount paid = 20 + 15x
185 = 20 + 15x
Subtract 20 from both sides
185 = 20 + 15x
185 - 20 = 20 + 15x - 20
165 = 15x
Divide both sides by 15
x = 165 / 15
= 11
x = 11 months
Answer:
∠b = 64°
Step-by-step explanation:
We know that a complete rotation is 360°, so:
∠b + 57° + 239° = 360°
∠b = 360° - 57° - 239°
∠b = 64°
Answer:
It's false.... correct is a2+2ab+b2
Step-by-step explanation:
This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.
That's why it's false.
Answer:
9= 71.67°
10= 60.65°
11= 86.59°
12= 62.30°
13= 34.51°
14= 51.71°
15= 22.87°
16= 44.63°
Step-by-step explanation:
The law of sine requires that if we have three sides of length A, B and C with their respective angles as a, b and c then these can be related by
