Answer:
2. 94.0 km/h
Step-by-step explanation:
since the airplane is moving at angle of 54° from the ground, the horizontal component of the velocity is given by cos component
speed of air plane= 160 km/hr
horizontal component of velocity v= 160 cos 54°
= 94.045 km/hr
Thus the truck must travel at an speed of 94.0 Km/hr hence second option is correct.
We will use addition to find the length of the new, longer hose.
6.25 feet + 5.755 feet + 6.5 feet = 18.505 feet is the length of the new longer hose.
What's the question?
If it's "What's the difference?" or something like that, then the answer is 15. :)
Answer:
x = 9.5
Step-by-step explanation:
We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:
3x - 6 + x + 2 = 34
4x - 6 + 2 = 34
4x - 4 = 34
4x = 38
x = 9.5
