b. 460 cubic cm
Step-by-step explanation:
When you multipy 1.229 x 15 your answer is 18.435. Rounding to the nearest cent will only include 2 numbers after the decimal. Looking at 18.435, the last number, 5 will round your answer to 18.44
If you are given with all the tree sides of the triangle, you may solve for all the angles through the Law of Cosines,
c² = a² + b² - 2ab(cos C)
where angle C is the angle opposite the side c. You may use the same equation to get the values of the remaining angle. Additionally, if you already have one known angle, you can solve for the rest of the angles by Law of Sines,
a / sin A = b / sin B = c / sin C
The vintage movie posters and the 2 rock posters could be priced the same, $8.
8 x 4 = 32.
the rap poster could be $6, but with the half-off coupon it comes to $3
32 + 3 = 35
assuming the gift card covers the total cost, this reasoning is correct.
