Answer:
THe expected annual cost is $282200
Step-by-step explanation:
We should take the base cost and sum it by the anual cost multiplied by 3, because the lifetime of the machines is 3 years. Since the expected return is 10%, then we have to multiply the result by 1.1, therefore
cost = (750000+12000*3)*1.1 = $864600
Now, we divide this by 3 to obtain the annual cost
Annual cost = 864600/3 = $288200
Answer: 67 degrees
Step-by-step explanation:
50 times 30 is 1500 and 9 times 8 is 72 added is 1572
Solution
For this case we need to find the number of cubes in the stack given so then we can do this:
The first line present 5 cubes
The second line present 5 cubes
And the last line we got:
10 cubes
Then the total of cubes are:
10 +5+5 = 20 cubes
If we need to find the number of faces we can do the following:
5+ 4+ 4+4 +4 +1 + (5+4+4+4+4+1 ) + (5+4+4+4+4+1 ) + (5+ 4+4+4 +4 )
And solving we got:
22+22+ 22+21= 87
