Answer:
Step-by-step explanation:
<u>The interior and exterior angles are supplementary:</u>
- A + 108° = 180°
- A = 180° - 108°
- A = 72°
Answer:
22.35 m/s
Step-by-step explanation:
The distance is always a positive unit, so distance traveled (d) = 15 miles
Time (t) = 0.3 hours
Time (t) = 0.3 * 60 = 18 minutes
(1 hour = 60 minutes)
Velocity (v) = ?
The formula of distance is: d = v*t
=> v = d/t = 15/18 = 0.83 miles/minute
we can also calculate velocity is meter/sec, for that
1 minute = 60 sec
=> 18 mins = 18*60 = 1080 sec
1 mile = 1609.34 meters
=> 15 miles = 15 * 1609.34 = 24,140 m
hence,
v = 24,140/1080 = 22.35 m/s
Answer:
4(b-6)=b^2
Step-by-step explanation:
The difference would mean that it is subtraction and you multiply that difference by 4 and set it equal to b squared
She needs at least 130 points, so 130 - 75 (that she is earning from the sign up) = 65 points.
65 : 5,5 = 11,81 ≈ 12
So she has to sign up and visit he movie theatre at least 12 times to earn a movie ticket.
