Answer:
k = 143
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°, thus
k = 180 - (27 + 10) = 180 - 37 = 143
To find this simply do 5!, or 5×4×3×2×1. That equals 120,
It does not say simple or compound interest.
Simple interest is rarely used these days, so assume compound.
Use the standard formula:
future value = present value*(1+rate/n)^(nt)
n=number of times interest is compounded per year (=1)
t=number of years
Plugging values,
200=100(1.09)^t
1.09^t = 2
take log
t(log(1.09))=log 2
t=log(2)/log(1.09)=0.6931/0.08618=8.04 years.
Hi there
I=prt
P principle 8000
R interest rate 0.095
T time 120/360
I interest earned?
I=8,000×0.095×(120÷360)
I=253.33
Hope it helps
