Answer:
starts at 36....marks up by 60%
36 + 0.60(36) = 36 + 21.60 = 57.60
now they mark it down by 20%
57.60 - 0.20(57.60) = 57.60 - 11.52 = 46.08
46.08 * 2 = 92.16
Step-by-step explanation:
To solve the volume of water in units of cubic meters, we
are going to convert first all units in terms of meter.
Let us say that the dimensions are:
length l = 4.40 nautical miles
width w = 3.90 nautical miles
depth h = 20 fathoms
Converting the dimensions to meters:
l = 4.40 nautical miles (6076 feet / nautical mile) (1
meter / 3.28 feet) = 8,150.73 m
w = 3.90 nautical miles (6076 feet / nautical mile) (1
meter / 3.28 feet) = 7,224.51 m
h = 20 fathoms (6 feet / fathom) (1 meter / 3.28 feet) =
36.59 m
The volume of a rectangular prism is:
V = l w h
Substituting the values:
V = (8,150.73 m) (7,224.51 m) (36.59 m)
V= 2,154,330,380 cubic meters
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
<u>Answer-</u>
<em>The cubic equation-</em>
<em></em>
<em>Milk consumption in 1994 was </em><em>58.4 pounds.</em>
<u>Solution-</u>
The general form of a cubic model is,
x = input variable = year - 2000 i.e number years after 2000
y = output variable = milk consumed in pounds
Then putting the values from the table,
--------------------------1
-------------2
-------------3
------------4
Solving equations (1), (2), (3) and (4) simultaneously we get,
So, the equation becomes,
In order to get the milk consumption in 1994, putting x=94
Therefore, milk consumption in 1994 was 58.4 pounds.
