I’m pretty sure it’s 1 1/3
Answer:
B
Step-by-step explanation:
This is the difference of perfect squares, which follows a pattern of
(A+B)(A-B)
We have 64, which is 8-squared,
we have A squared, which is A squared ( :/ )
we have 81, which is 9-squared, and
we have B-squared, which is B squared.
We can factor this then following the pattern into:
(8A+9B)(8A-9B)
Choice B only matches one of our binomials.
The main formula is
M= P (i(1+i)^n) / <span>(1+i)^n) - 1
M: monthly payment
P: mortgage principale= </span><span> $20,230
i=montly interest, 11.5%=11.5/100=0.115, i= 0.115/12=0.009
n=number of months=12x20(years)=240 months
M= </span>$20,230(0.009(1.009)^240) / (1.009)^240-1=<span>$20,230 x 0.0077 / 8.58-1
M=$20.57
</span>
Answer:
a = 16*3.1415/3 = 16.76
Step-by-step explanation:
a =pi*r^2
r =D/2
r = 8/2
r = 4
a = pi*4^2
a=pi16
pi = 3.1416
The scale factor would be 1.25 because each segment is the same in this triangle
