180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
A.) borrower must pay off the loan.
Answer:
19.1
Step-by-step explanation:
Let's assign some variables to this triangle.
angle A = 63°
angle B = unknown
angle C = 71°
side a = 18
side b = y
side c = x
By the law of sins, applicable to ALL triangles, we have:

Let's then take the equation for angles A and C, in order to isolate the c (which is our x to find).
we then have

So, the answer is the second one.
Divide the cost, 9, by 15 to get the cost per cookie: 6 cents
Answer:
C
Step-by-step explanation:
A geometric sequence has a common ratio r between consecutive terms
A
4 ÷ 2 = 2
6 ÷ 4 = 1.5
Thus not a geometric sequence
B
1 ÷ 1 = 1
2 ÷ 1 = 2
Thus not a geometric sequence
C
÷ 1 = 
÷
= 
÷
= 
D
4 ÷ 7 = 
1 ÷ 4 = 
Thus not a geometric sequence
Then the geometric sequence is C
