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
V = 36 pi centimeters cubed
Answer:
C. 3/5
Step-by-step explanation:
Probability that M will occur =1-0.8=0.2=1/5
Probability that R will occur = 1-0.6=0.4=2/5
Probability that either of them will occur= 1/5 + 2/5= 3/5
C = 82.8°
<span>b = 27.5 </span>
<span>Here's the working in case you need to see it. </span>
<span>Using Law of Cosines to first find b: </span>
<span>b² = a² + c² - 2acCOS(B) </span>
<span>b² = (41)² + (20)² - 2(41)(20)COS(36) </span>
<span>b = about 27.5 </span>
<span>Now using Law of Sines to find A </span>
<span>sin(36) / (27.5 = sin(A) / (41) </span>
<span>sin(A) = 41sin36 / 27.5 </span>
<span>sin(A) = 0.876334376145 </span>
<span>A = SinInverse(0.876334376145) </span>
<span>A = about 61.2° </span>
<span>Now using 180-61.2-36 to find B = 82.8° </span>
<span>Have a good day! </span>
Answer:
use a midpoint formulae (X2+X1 /2 ; Y2 + Y1 /2 )
(-2+3/2 ; -2+4/2 )
X = 1/2 ; Y = 1
