Answer:
A_ 1,2,4,5,-1, or,-2
3 plus any of these will always leave you with a positive number of 1-8
B_ -1, -3, -4, -5, or 1
-2 plus any of these will leave you with a negative number of -7 through -1
C_ 1+(-1)
2+(-2)
3+(-3)
4+(-4)
5+(-5)
since all the numbers are 1-5 are both negative and positive these will cancel out and equal to zero.
Step-by-step explanation:
1/8 or 1 in 8. There are 8 sections and only one is yellow. Therefore, you have a 1/8 chance of spinning yellow. As a percent it would
be 12.5%
X=11
The triangle equals to 180
Hope this helps!!
This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence:

If a1=1.6 then:

The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
