School A : 750 + 200 = 950 per semester
School B : if u get a 10% discount, then ur actually paying 90%
0.90(1000) = 900 per semester
The best deal would be school B...u would save $ 50 per semester by choosing B over A
Answer:
141.3 km
Step-by-step explanation:
First crater has the radius (that is, half the diameter) of 7.5 km; the circumference of this crater is C = 2(pi)r, or 2(3.14)(7.5 km) = 47.1 km;
Second crater radius is C = 2(pi)(30 km) = 188.4 km
The circumference of the complex (larger) impact crater is
(188.4 - 47.1) km greater than the circumference of the simple (smaller) crater:
141.3 km
