Answer:
9.42 m
Step-by-step explanation:
Arc AB = 2πr x (45/360)
= (2 x 3.14 x 12) / 8
= 9.42
Answer:
18.3
18.3 only has three significant figures while the other numbers have more
Answer:
y = 4
Step-by-step explanation:
Given that y varies jointly with x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 16 when x = 4 and z = 
, that is
16 = k × 4 × = 2k ( divide both sides by 2 )
8 = k
y = 8xz ← equation of variation
When x = 2 and z = 
, then
y = 8 × 2 × = 16 × = 4
35) that external angel is the 2 given angles added together (30 + 80 = dba)
36) same property (110 = 40 + x)
37) same property ( (x-20) + (3x-60) = 2x + 20)
40) I dont know either but I'm pretty sure that the type of angle that x is determines the triangle.
Answer:
1/10
Step-by-step explanation:
the probability of your first pick was 1/5, if not retured=ned, the probability of you getting an even number next will then be 2/4. (1/5)(2/4)=1/10
