Answer:
x = 105°
Step-by-step explanation:
interior angle of regular polygon = (180 x (n - 2)) / n
hexagon: (180 x 4) / 6 = 120
octagon: (180 x 6) / 8 = 135
x = 360 -120 -135 =105°
A = number of $1 bill
B = number of $5 bill
A + B = 1919
A*$1 + B*$5 = 5959
so
A + B = 1919
A + 5B = 5959
Substract both equation
A + 5B - (A + B) = 5959 - 1919
4B = 4040
B = 1010
And
A = 1919 - B = 1919 - 1010 = 909
A = 909
Check the result :
A*$1 + B*$5 = 909 + 1010*5 = 909 + 5050 = 5959
Answers:
1, 6, 36, 216: Geometric
12, 4, -4, -12: Arithmetic
1, 2, 8, 64: Neither
-216, -72, -24, -8: Geometric
Explanations:
Arithmetic Sequence: Every number in the sequence is either added or subtracted by the same number. We know that 12, 4, -4, -12 is arithmetic because each number in the sequence is subtracted by 8.
Geometric Sequence: Every number in the sequence is either multiplied or divided by the same number. We know that 1, 6, 36, 216 is geometric because each number in the sequence is multiplied by 6. We also know that -216, -72, -24, -8 is geometric because each number in the sequence is being divided by 3.
Neither: 1, 2, 8, 64 is neither because it is not being added, subtracted, multiplied, or divided by the same number.
I hope this helped!
