Answer: $56.20
Step-by-step explanation:
Both the tax and the tips will be based on the total cost:
Tip = 43.57 * 20%
= $8.71
Tax = 43.57 * 9%
= $3.92
Total = Cost + Tip + Tax
= 43.57 + 8.71 + 3.92
= $56.20
Answer:
I'm going out on a branch and say B
Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
