It is 12 because there are 180 degrees in a set of supplementary angles and 12 times 10 equals 120, plus 60 equals 180.
25$ because if you bout something that was 25$ 25$ off would make it free but 25% off would make it 6.25
a[n] = 7n - 16
The fifth term is a[5]
a[5] = 7(5) - 16 = 35 - 16 = 19
Answer: C. 19
The answer is <span>B.154/d = 44/14
</span>
<span>In a circle, the circumference (C) and diameter (D) vary directly:
C = kD
k = C/D
Circle 1: k = C1/D1
Circle 2: k = C2/D2</span>
C1/D1 = C2/D2
C1 = 154
D1 = ?
C2 = 44
D2 = 14
154/D1 = 44/14
So, the choice B. is correct.
Answer:
3
Step-by-step explanation:
