Each exterior angle = 360 / 40 = 9 degrees. So each interior angle = 180 - 9
= 171 degrees.
Hi there
The formula is
A=p (1+r)^t
A future value?
P present value 1020
R rate of increases 0.03
T time 2,015−2,001=14 years
So
A=1,020×(1+0.03)^(14)
A=1,542.8 round your answer to get
A=1543
Hope it helps
Answer:
x=-3, y=-19
Step-by-step explanation:
we can solve by substitution.
y = 2x-1 we can derive from the second equation.
plugging it into the first equation, 2x -3(2x-1) = 15.
simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.
now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1
simplify, 18+y = -1 --> y = -19.
Answer:
Circumference = 39.6 cm
