13 dollars per gallon
130\10 = 13
This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
Answer:
156ft would be the answer
Step-by-step explanation:
Simple, 184-28=156. If it was the area you would divide 184 by 28 to get about 6.57.
L+W=P
aka length + width= perimeter. But LxW=Area, LxW=A, or bXh (base times the height)
You'd first have to find out what percentage of people would be 30 out of 100%
C = 2 pi r
C = 2 x 3.14 x 5
C = 31.4 yd
A = pi r^2
A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 yd^2
