Answer:
$6.48
Step-by-step explanation:
It would be $6.48 because 1.60 times 4 1/2 is 7.2 and if you do 10% of 7.2 you get B.
Begin by using the cosine rule to find the unknown side.
Where a- unknown side, b is 12, c is 16 and angle in between is 108°
The cosine rule...
a² = b² + c² - 2bc cosA
= 12² + 16² - (2×12×16 cos108°)
= 518.655076
Taking the positive
square root...
a = 22.774
a = 22.8 cm nearest tenth

Answer:
B- 7/12 and 17/18
Step-by-step explanation:
Get the fractions under a common denominator.
- A: 1/3=6/18. 5/6=15/18. 4/9=8/18.
- B: 7/12=21/36. 5/6=25/36. 17/18=34.
- C: 11/12=33/36. 5/6=25/36. 31/36=31/36.
- D: 1/4=6/24. 5/6=20/24. 5/8=15/24.
Out of A, B, C, and D– only B works.
