Answer:
Step-by-step explanation:
According to the problem, the hot-air ballon and the wind are movind in the same direction, which means the component form of the velocity of the ballon is the net vector between both velocities.
Basically, the net velocity is
Because both velocities have the same direction.
Assuming they are moving in a horizontal direction, the component of this velocity is
x = 5.
I attached an image of my work!
Step 1: Subtract 8 from both sides
4x = 20
Step 2: Divide each side by 4
x = 5
Answer:
C
Step-by-step explanation:
When doing 4 divided by 2 you get 2. Looking at the sign it is saying 3 is greater than the number we solve for. Since we solved and got 2 we can double check and ask is 3 greater than 2? Yes it is so that would make the statement correct.
Hope this Helps :)
Answer:
10/18
Step-by-step explanation:
3/18 +7/18 =10/18
Answer:
a) 2 1/8 miles per hour
b) 8/17 hours per mile
Step-by-step explanation:
To find the rate in mile per hour, divide miles by hours:
(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = 17/8 mi/h = 2 1/8 mi/h
__
To find the rate in hours per mile, invert that number:
1/(17/8 mi/h) = 1/((17 mi)/(8 h)) = (8 h)/(17 mi) = 8/17 h/mi
