Answer: 10 years
Explanation:
The original cost of the machine = 20000
The scrap value of the machine = 13122
Value of the machine = ( 20000 - 13122 ) = 6878
Depreciation of the machine for the first year = ( 6878 * 10 % )
= 687.8
So, the effective life of the machine is = ( 6878 / 687.8 )
= 10 years
6 is the answer 6,12,18,24,30
Answer:
The 2 factors are -2 and 18.
Step-by-step explanation:
xy = -36
Let y = 0.5x - 11 so
x(0.5x - 11) = -36
0.5x^2 - 11x + 36 = 0
0.5(x^2 - 22x + 72) = 0
(x - 4)(x - 18) = 0
x = 4, 18.
Try x = 18:-
The 2 numbers which are factors of -36 must be -2 and 18 because they fit the requirement that 0.5(18) - 11 = 9 - 11 = -2.
