Answer:
the runners have gone 20.8 times around the globe all together
Step-by-step explanation:
At the Bostom Marathon, we have a total of
N = 20,000 runners
We know that each runner ran a distance of
d = 26 miles
Therefore, the total distance travelled by all runners combined is:

We know that the circumference of the Earth is

Here we want to find how many times around the globe would the marathon runners have gone. This can be found by calculating the following ratio:

And substituting the values, we find:

So, the runners have gone 20.8 times around the globe all together.
Shane:
8 x 3 = 24 Because it is 8h per day for 3 days. Per is like times
24h out of 36 24/36 GCF is 12 divide to and bottom by 12
24 / 12 is 2 36 / 12 is 3 2/3 Shane worked for 2/3 of 36h
Percentage: 100% / 3 (because there is 3 parts)= 33.333333333333
33.33333333333 x 2 (because it is there is 2 parts needed) = 66.6666666666%
Shane has worked for 66.6666666666% of 36 hours
Andrew:
4 x 6 = 24
Hey did you realise, the 24 is exactly the same! So the fraction would still be 2/3 of 36, and so on, there percentage is still the same, it's still 66.6666666666%
Answer: Both of Andrew and Shane has worked for the exact same time, therefore they have the exact same percentage <span />
Answer:
50
Step-by-step explanation:
I assume you are asking how much she EARNS after 2 years.
500x.-5=25 interest per year
25 x 2 years = 50 interest for 2 years.
I believe the answer is: -190.98
