Total distance = sum of velocity * time for both legs of the journey; let the time taken in air be t hence time taken in water is 12-t 127 = 16*t + 3(12-t) 127 = 16t + 36 - 3t 127 - 36 = 16t - 3t 91 = 13t t = 91/13 = 7 seconds Hence time taken in air = 7 seconds time taken in water is 12 - 7 =<span> 5 seconds</span> checking; 16*7 + 3*5 = 127
The answer is D
They have the same slope but different yint.

Answer:
y =71
Step-by-step explanation:
The sum of the angles of a triangle add to 180
y+y+38 = 180
Combine like terms
2y +38 =180
Subtract 38 from each side
2y+38-38 =180-38
2y = 142
Divide each side by 2
2y/2 =142/2
y = 71
Answer:
291
Explanation:
an hour contains 60 minutes and because you want to know the shuttle is moving per minute you also divide 17,460 by 60 so 17,460÷60= 291 miles per minute.
