Sexy question - basic physics - can anyone solve any of these 2 problems?

Question

1.) John and Mary Smith plan to put a wooden
fence around their yard in order to keep the
mean cats away from their dog Fido. There
is a gate that is 2.45 m long which is not
included as part of the length of the fence.
What total length of fence is required to
enclose a rectangular yard whose sides are
28.4 m and 34.4 m in length? 1 m = 3.281 ft .
Answer in units of ft.

(please show work - thank you very much)

2.
A billionaire offers to give you $4.9 billion if
you will count out the amount in $1 bills or
a lump sum of $4000. Assume that you can
count at an average rate of one bill per second,
and be sure to allow for the fact that you need
about 10 hours a day for sleeping and eating.
Which offer should you accept?
In order to answer this, how long will it take
you to count out the $4.9 billion? Answer in
units of years.

Answer 1

Do you're own homework or else you'll never learn.

Answer 2

1. To solve this problem, you'll first need to find the total length of the perimeter in meters, subtract the length of the gate which will give you the fence length, then convert that to ft.

Ok, lets first start with the perimeter.

((2 x 28.4 m) + (34.4 x 2)) - 2.45 m = Fence length

(56.8m + 68.8m) - 2.45 m = Fence length

125.6 m - 2.45 m = Fence length

Fence length = 123.15 m

Now we'll use dimensional analysis to convert the length from meters to feet.

123.15 m x (3.281 ft / m) = Fence length

123.15 * 3.281 m*ft / m = Fence length

Meters will cancel out like a variable

404.06 ft = Fence length Final answer.




2. To do this we're going to have to use some dimensional analysis to solve this one. First we'll find out how many seconds are in a 14 hour period, because you'll be counting the $1 bills for that period in a day.

$1 bill / 1 sec = bills counted

14 hr x (3600 sec / 1 hr) = bills counted per day

14 x 3600 hr*sec / hr = bills counted per day

50,400 sec = $50,400 bills counted per day.

Now we'll divide the the amount of bills counted per day into the total $4.9 billion to find out how many days we'll be counting bills for since we've already got the amount we've counted in a waking 14 hr day.

$4.9 x 10^9 / $50,400 = days counting bills

97,222.22 = 14 hr days counting bills.

Now we can convert the number of here into years.

97222.22 days x (1 yr / 365.25 days) = Time to count bills

The days cancel out leaving yrs

97222.22 yr / 365.25 = Time to count bills

266.18 yrs = Time to count bills.

I'd say to take the $4,000 lump sum because you'll be dead before you're even half way through counting. Final answer.

Answer 3

If you can't answer the question, folks, don't post an answer. I'll give it a go.

Question 1:
2 x (28.4 + 34.4) = 125.6 m (perimeter)
125.6 - 2.45 = 123.15m (less gate width)
123.15 x 3.281 = 403.93 ft. (403ft., 11.16in.)

Question 2:
4.9 x 10^9 / 60 = 8.17 x 10^7 sec.
8.17 x 10^7 / 60 = 1.362x 10^6 min
1.362 x 10^6 / 60 = 2.27 x 10^4 hr.
2.27 x 10^4 / 14 = 1,621.43 days (accounting for 10hr./day rest)
1,621.43 / 365 = 4.44 yrs.
