Answer:
$77,558.55
Step-by-step explanation:
A fix periodic payment for specific period of time.
We need to calculate the present value annuity to determine the value of investment today.
Present value of annuity = P x ( 1 - ( 1 + r )^-n / r )
where
P = Periodic payment = $12,000
r = interest rate = 10% / 2 = 5%
n =numbers of payment = 4 years x 2 = 8 payments
Placing values in the formula
Investment Value today = $12,000 x ( 1 - ( 1 + 5% )^-8 / 5% )
Investment Value today = $77,558.55

Answer:
3 hours
Step-by-step explanation:
The pool was filled at noon = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
After
hours the fool was filled = ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
So,water filled in pool in
hours = ![\frac{3}{4}-\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D-%5Cfrac%7B1%7D%7B3%7D)
So,water filled in pool in
hours = ![\frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B12%7D)
of pool is filled in hours =
Whole pool is filled in hours =
Whole pool is filled in hours =
Hence it took 3 hours the pump to fill the pool .
14x-3x= 11x and the 17 stays the same, so the answer is 11x/17 or answer B.
8•25•23=
25 eight times is 25 four times + 25 four more times
((25•4)+(25•4))•23= (100+100)•23= 200•23= 2•23•100= 46•100= 4,600
