the answer should be C. 5.27
WE KNOW THAT THE VOLUME OF THE CUBE IS '
V=a^3
our a=7
V=343 cm^3
3/4 + 1/12 = 10/12 and then you simplify it and get 5/6 as your final answer.
Step-by-step explanation:
3/4x+3-2x=1/4+1/2x+5
x=2/-3
Answer:
C. 6,000 km
Step-by-step explanation:
v = speed at S-wave travel through the earth = 8 km/sec
t = time of travel for the S-wave through the earth = 13 minutes = 13 x 60 seconds = 780 seconds (Since 1 minute = 60 seconds)
d = distance traveled by S-wave in the given time interval
Distance traveled by S-wave in the given time interval is given as
d = v t
inserting the above values in the formula
d = (8 km/sec) (780 sec)
d = 6240 km
the closest choice is 6000 km at option C
So Option C
