U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
the correct answer should be f-52=63
Step-by-step explanation:
Answer: First, add 3.99 + 7.17. Then take the sum of those two numbers and multiply it by .05 to get 0.55. Since we are dealing money, round to the nearest hundredth to get .56. Add the sum of 3.99 and 7.17 (11.16) and .55 to get a total of 11.71. Therefore the total cost of their dinner, including tax, was $11.71.

Answer:
B
Step-by-step explanation:
From the figure, we can say:
∠NFG + ∠EFN = ∠EFG
We substitute the given measure and write:
6x + 4 + 24 = 12x - 2
Now, we simply solve this algebraically for "x". Shown below:
x is 5, so B is the correct answer.
