Answer:
0.4 sec
Step-by-step explanation:
Remember that
1 mile=5,280 feet
1 foot=12 inches
1 hour=3,600 seconds
Let
s -----> the speed in ft/sec
d ----> the distance in ft
t -----> the time in sec
s=d/t
Solve for t
t=d/s
step 1
Convert miles/hour to ft/sec
105 mi/h=105(5,280/3,600)=154 ft/sec
Convert 60 ft 6 in to ft
60 ft 6 in=60+(6/12)=60.5 ft
step 2
Find the time
t=d/s
we have
s=154 ft/sec
d=60.5 ft
substitute
t=60.5/154
t=0.39 sec
Round to the nearest tenth
t=0.4 sec
Since 1973, social security numbers have been issued by our central office. The first three (3) digits of a person's social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by our field offices. The number merely established that his/her card was issued by one of our offices in that State.

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
FORMULA:
- Pythagorean theorem —: h² = b² + p², where h = hypotenuse, b = base, p = perpendicular.
ANSWER:
Pythagoras theorem consists of a formula a² + b² = c² which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent).
