I would say C, because it makes the most sense
Answer: 0.15 m
Step-by-step explanation:
Using the small angle formula
D= kd/206265 where
k= 22 and d= 1400
D= 22 x 1400/206265
D=0.149 m
Hence the linear diameter is 0.15 m.
Three times four is twelve so 6+6=12or9+3=12
Answer:
second option
Step-by-step explanation:
x + y = 18 → (1)
4x - 3y = - 12 → (2)
Multiplying (1) by - 4 and adding to (2) will eliminate the x- term
- 4x - 4y = - 72 → (3)
add (2) and (3) term by term to eliminate x
0 - 7y = - 84
- 7y = - 84 ( divide both sides by - 7 )
y = 12
Substitute y = 12 into (1) and solve for x
x + 12 = 18 ( subtract 12 from both sides )
x = 6
solution is x = 6, y = 12
