Answer:
i think it might be fact families
Step-by-step explanation:
this is because they use the 3 same #rrs
There are two coefficients in this equatin,why because we have two variables "x and y " . Therefore the coefficients are (+6 for variable x) and (+14 for variable y) and we have only one constant...why? because we can only have one constant in a given equation.
Answer:
401/99 and 802/198
Step-by-step explanation:
Unfortunately the other answer to this question is wrong - you are looking for something equivalent to 4.0505050505050505, not just 4.05.
Typing the answer suggestions into a calculator you get:
405/99 = 4.0909090909 which is incorrect
401/99 = 4.0505050505 which is correct
81/33 = 2.45454545455 which is incorrect
802/198 = 4.0505050505 which is correct
405/100 = 4.05 which is incorrect as it doesn't repeat.
Hopefully this helps, let me know if you have any questions :)
Answer:
$ 50,340.97
Step-by-step explanation:
From the above question, we can deduce that we are to find the Initial amount invested which is also called the Principal.
The formula to find Principal in a compound interest question is:
P = A / (1 + r/n)^nt
Where:
A = Total Amount obtained after invested = $80,000
r = Interest rate = 3.1% = 0.031
n = number of times interest in compounded = Quarterly = 4
t = time in years = 15
P = $80,000/(1 + 0.031/4)^4 × 15
P = $80,000/(1 +0.00775)^60
P = $ 50,340.97
Hence, James would have to invest $50,340.97 today to have $80,000 in 15 years.
