Answer:
500m
Step-by-step explanation:
a rectangle has 4 sides, so 30=60 and 20=40
60x5=300
40x5=200
300+200=500
500m
reason of 500
The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.
Answer:
Step-by-step explanation:
As stated in the question, the probability to toss a coin and turn up heads in the first try is
, in the second is
, in the third is
and so on. Then, P(C) is given by the next sum:

This is a geometric series with factor
. Then is convergent to
. With this we have proved that P(C)=1.
Now, observe that

Then



and

What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).
So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.
Now you will connect the line M and Z.
Thats it! I hope this helped!! :)
