Answer:
2√6cm
Step-by-step explanation:
Area = L×L
A=L2
24 =L2
√24 =√L2
2√6= L
:.L =2√6.cm.
Answer:
3x-x+2=4
Step-by-step explanation:
This is a distance problem so we can use distance = rate x time.
Given: the distance to the telephone is the same as the distance back from the telephone. We also know the two speeds and the total time for the trip.
But first let's convert 15 minutes into seconds: 15*60 = 900 seconds.
So: d = 5(t1) (t1 is the time he took to run to the telephone)
d = 4(t2) (t2 is the time he took to come back from the telephone
t1 + t2 = 900 or t1 = 900 - t2
Now use substitution:
5t1 = 4t2
5*(900 - t2) = 4t2
4500 - 5t2 = 4t2
4500 = 9t2
500 = t2
So therefore t1 = 400
So the distance to the telephone is 5*400 = 2000 meters
Two negative make a positive note matter what
Hello Pirates6027,
After reading your question, the answer is fairly simple.
Just add the numbers and divide by the amount of numbers there are for the mean, which comes out to be 913.8. For the median, order your numbers and find the middle number, which is: 38.
Hope this helps!
