1/4
Step-by-step explanation:
Answer:
F = 100(.5736)
= 57.36 lbs. (rounded off to 2 decimal places)
2) sin60 = .866
F = 18(.866)
= 15.59 lbs. (rounded off to 2 decimal places)
Step-by-step explanation:
F = friction
Answer:
- A: 16,000,000 carats
- B: 4,000,000 carats
Step-by-step explanation:
If the ratio is ...
A : B = 4 : 1
Then the ratio to the total is ...
A : total = 4 : (4+1) = 4 : 5
B : total = 1 : (4+1) = 1 : 5
Country A produces (4/5)×20 M carats, or 16 million carats.
Country B produces the remainder, 4 million carats.
Sin(2x-8)=cos(90-2x+8)=cos(6x-6).
So 98-2x=6x-6, 104=8x, x=13.
2x-8=18, 6x-6=72. The smaller angle is 18 and the larger angle is 72.
