Answer:
ACV=$4,500
Step-by-step explanation:
We have that the actual cash value (ACV) is defined as:
Where:
actual cash value
replacement cost or purchase price of the item
expected life of the item
current life of the item
Then we have R=$6,000, C=5years, and to find the expected life of the item we can use the depreciating of the roof, then if the roof is depreciating $200 each year we just need to divide $4,000 by $200 to find the expected life of the roof:
Then the espected life of the roof is 20 years, with this result we have all the data, then:
Then the ACV is $4,500
Answer:
Step-by-step explanation:
-1/2x -7=-11
-1/2x +4=0
4=1/2x
x=8
Answer:
It is not correct, the answer is 15
Step-by-step explanation:
They forgot the rule of PEMDAS, and accidentally subtracted before they multiplied. It should've gone
(25+3) - 7 x 3 + (2x4)
28-7x3+8
28-21+8
Since it's minus 21, that means it's negative, so -21+8=13
28-13=15
Dividing by 2, we have S/2=lw+lh+wh. After that, we subtract lh from both sides to get S/2-lh=lw+wh. Next, we divide both sides by w to get (S/2)/w=l+h. Next, we divide by S/2 to get 1/w=(l+h)/(S/2). Lastly, we multiply by w and divide by (l+h)/(S/2) to get w=(S/2)/(l+h)
