Answer:
okay, you have pay special attention to time.i.e 60secs = 1 minute, 60 minutes = 1 hour, 24 hours in one day, and 7 days in one week. No. of seconds in one week we are told is 6.1048 x 10 ^5 seconds.
Step-by-step explanation:
s = d/t [ speed = distance/time]
therefor, rearranging, we get d = s x t
Since speed = 2.998*10^5 Km/s and time = 6.048^10^5
d = (2.998 x 10^5) x (6.048 x10^5) = (2.998 x 6.048) x 10 ^(5+5)
d = 18.131904 X 10^10 km
d = approximately 18.132 x 10^10 km (to 3 decimal places)

Answer:
B. cost(time)
Step-by-step explanation:
In the information given above, you can eliminate choices "A," and "D," since they're just using the cost of a repair and the time the mechanic works. This leaves us with either "B," or "C." The correct answer is "B," because the cost of the repair depends on whatever is inside the parenthesis (the time).
Answer:
$180
Step-by-step explanation:
step one 86+4 =90
step two 90×2=180
Given x = adjacent
10 = hypothenuse
Sohcahtoa (cah)
Cosine uses both adjacent and hypothenuse
x/10 = cos(37)
0.79863551 = x/10
x = 7.9763551
Solution: x = 8
