Step-by-step explanation:
Because the cosine of beta is : cos(B) = BC/AB
Answer:
multiply 77 by 10 which is 770 then you multiply it by 5 which is half of 10 so 385 then add them together and you get 1155
Answer:
1164
Step-by-step explanation:
Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.
384 + 600 + 192 = 1164
There are 24 segments on the wheel in total. 1 segment is the $500 and 2 are the bankruptcy spaces. You would then multiply the two fractions 1/24 and 2/24 (the chances of getting each result) to get the answer. 1•2=2 and 24•24=576 making the fraction 2/576. Then you would simplify by dividing both sides by 2 which equals the final answer 1/288.
x-4 needs to be greater or equal to zero so
[4, ∞) is the answer
