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.
Answer:
Simple, 4*pi*r^2
Step-by-step explanation:
Answer:
slope = 3
Step-by-step explanation:
5 - x1 -5 - y1
-1- x2 7 - y2
m= y2 - y1 / x2 - x1
m= 7 - (-5) / -1 -(-5)
m= 12 / 4
m= 3
Answer:
84 yards (don't forget to label, as my friend failed a test because of it!)
Hope this helps
Step-by-step explanation:
The total perimeter of the field is 358
The are length and widths...
the length is 95
but since there are two lengths...
its 95*2 which is 190
358-190=168
Since there are two widths...
168/2= 84
