Answer
Find out the how many comic books does Jim have.
To proof
Let us assume that comic books Jim have be u.
Let us assume that comic books Charlie have be v .
Let us assume that comic books bob have be w .
As given
jim has three times as many comic books as Charlie
thus
u = 3v
Charlie has two thirds as many books bob.
Thus
bob has 27 books .
i.e w = 27
Put this in the equation
Solving
v = 18
thus
comic books Charlie has be 18 .
Put v = 18 in the u = 3v
u = 3 × 18
= 54
comic books Jim has be 54 .
Hence proved
The given scenario above is like a geometric sequence with r or common ratio being 1.05 and the first term being 31 square meters. The nth term of the sequence is calculated through the equation,
A15 = (A1)(r)^(n - 1)
Substituting,
A15 = (31)(1.05)^(15 - 1) = 61.3778 square meter
Therefore, the area covered by the spill after the 15th day is approximately 61.4 square meters.
Answer:
Equation of the line is y = -x + 4
Step-by-step explanation:
When the two lines having their slopes 
and 
are perpendicular to each other then 
If is the slope of the line passing through two points (0, 3) and (4, 7) then
= 
= 1
Now slope of the second line perpendicular to first line will be
= 
= -1
Slope intercept form of the equation of a line is represented by
y = mx + c
where m = slope
c = y intercept
Since the line is passing through (-1, 3) and slope = -1, therefore,
3 = -1 + c
c = 4
Now we plug in these values in the equation.
y = -x + 4
Equation of the line is y = -x + 4
Answer:

Step-by-step explanation:
The cost is 24 cents per foot.
We find this by dividing the cost of the roll by the number of feet in the roll:
47.03/200 = 0.235 ≈ 0.24
