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
0.22 because one side is 11 and the other is 11 so 11+11 is 22 the pursent of 22 is 0.22
Answer:
A) 6,3
Why?
The midpoint, which is somewhat self-explanatory thanks to its name, is a point in the center of a line.
To answer this question properly, you need to analyze the line and assess the situation.
How did it go from x = 2 to x = 10? Let's see, if we count by two's across the line, you'll notice it makes more sense. So now we know that every square goes up by two. x = 6 is the exact center of the line.
I hope this wasn't confusing, it's tough to explain it!
Add the amount of students together (21+24=45)
Divide by three to see how many will be in each group. (45/3 = 15)
15 in each group!
