519 km....ok, lets convert it to centimeters
there are 1000 meters in 1 km, so in 519 km, there are 519 * 1000 meters then.
there are 100 centimeters in 1 meter, so in (519 * 1000) meters, there are then (519 * 1000) * 100 centimeters.
that's how many centimeters Los Angeles is from San Francisco.
now, the slip rate is 2.1 cm per year.
how many times does 2.1 go into (519 * 1000 * 100)?
well, is just (519 * 1000 * 100) / 2.1.
that many years.
Answer:
(3,0)
Step-by-step explanation:
58 DAYS, WITH EACH DAY BEING 24 HOURS, EQUALS HOW MANY HOURS TOTAL RIGHT
58/1 * 24/1
THE DAYS CANCEL EACH OTHERS OUT, LEAVING 1,392 HOURS
30/1 * 1/60
THE MINUTES CANCEL EACH OTHERS OUT AND 30/60 IS SIMPLIFIED TO HALF AN HOUR
FINALLY YOU ADD 1,392+15+0.5 TO GET A FINAL RESULTS OF 1,407.5 HOURS
Answer:
B = 48.7°, C = 61.3°, b = 12.0
Step-by-step explanation:
A triangle solver makes short work of this. (See below.)
_____
If you're interested in solving this using only calculator trig functions (and not the solver function), you can use the Law of Sines:
sin(C)/c = sin(A)/a
sin(C) = (c/a)sin(A)
C = arcsin(c/a·sin(A)) = arcsin(14/15·sin(70°))
C ≈ 61.3°
From the sum of angles, the third angle is ...
B = 180° -A -C = 180° -70° -61.3°
B = 48.7°
Again from the Law of Sines:
b/sin(B) = a/sin(A)
b = a·sin(B)/sin(A) = 15·sin(48.7°)/sin(70°)
b ≈ 12.0
