Answer:
36 minutes
Step-by-step explanation:
time = distance / speed
time = (7.2×10² km)/((1.2×10³ km)/(60 min)) = (7.2×60/1.2)×10²⁻³ min
= 360×10⁻¹ min
= 36 min
It takes sound about 36 minutes to travel 720 km.

Step-by-step explanation:
Answer:
The answer is C
Step-by-step explanation:
Every negative or positive number in the modulus while be positive at the end
363 in^2
The radius is 11 (as shown in the diagram).
A = pi(r)^2
pi = 3
3(11)^2 = 3*121 = 363 in^2
