Answer:
0.2
Step-by-step explanation:
Basically, all you would do is 120/540. Which is the same thing as division. So: 120 / 540 = 0.2
Answer:
I believe it would be $866.07
Step-by-step explanation:
All you need to do is 487.78+378.29 right?
I could be wrong-
Let there be x sides.
180(x-2)/x=11*360/x
180(x-2)=11*360
x-2=11*2
x-2=22
x=24
the polygon has 24 sides.
Answer:
Tn = -4n²+40n+36
Step-by-step explanation:
A general quadratic sequence, Tn = an²+bn+c, where n is the term of the sequence.
So, when n = 1, Tn = 72, which means T1 = a+b+c=72.
when n = 2, Tn = 100, which means T2= 4a+2b+c = 100
when n = 3, Tn = 132, which means T3 = 9a+3b+c = 132.
Now, use a calcaulatot to solve the 3 variable simultaneous equation. According to my calculator, a = -4, b = 40, c = 36.
Hence, you a, b, and c in the Tn equation given above.
Therefore, <em>Tn = -4n²+40n+36</em>
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
