Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u
Speed of current = v
Let distance between A & B = 100 km
Time taken in downstream = 32 hours
u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours
u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045
v = 0.5205
Now the time taken by the un powered raft to cover this distance
Because un powered raft travel with the speed of the current.
T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
Answer: 8 + x = 3
To solve for this, we need to get x by itself on one side of the equation.
Currently, we have 8 being added to x, so we need to perform the opposite order of equations to get rid of 8.
The opposite of +8 is -8, so subtract 8.
Remember, if you add, subract, multiply or divide by any new number, you must do it to both sides of the equation.
8 + x = 3
Subtract 8 from both sides.
8 - 8 = 0
3 - 8 = -5
We're now left with:
x = -5
Your answer is A.) -5.
I hope this helps! can u pls give me brainliest
Step-by-step explanation:
Answer:
I know #1 is a
Step-by-step explanation:
#1 is a because the bus stops twice reaching zero speed to pick up riders then he stops again but since he has to slow down it's not a instant stop so it gradually decelerates twice but since it has a speed it has a constant line (straight) another easy way to tell us to look at the speed and then look the the graph and see if they match so you can elimnate a answer
I think this would be (y = -2x + 9). Let me know if it is right!
