Answer:
Seb will take 13 minutes and 20 seconds to run 4000 m at an average speed of 5 m/s
Step-by-step explanation:
time taken = distance / speed
time taken = 4000/5
time taken = 800 seconds
time taken = 13 minutes and 20 seconds
Answer:
1/7, 14.3%
Step-by-step explanation:
Since out of the 7 numbers, only one of them is 3
Therefore only 1/7 meet the standards, in percent form it is 14.3%
Answer:
3 hours and 51 minutes
Step-by-step explanation:
Take the ending time and subtract the start time
3:13pm - 11:22am
Remember that pm means aft 12 o'clock in the after noon so add 12 hours
12+3:13 - 11:22
15:13 - 11:22
We are subtracting more minutes than we have so we have to borrow from the hours
1 hour = 60 minutes
14 : 60+13 - 11:22
14:73 - 11:22
3: 51
3 hours and 51 minutes
Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.
If there are 5 specific spots and the order does matters then we would have:
11*9*8=792
Hope this helps!
