Answer:
Step-by-step explanation:
From the diagram in the image attached:
Base of triangle =
Base of triangle =
Height = 9cm
Area of triangle = (0.5) × base × height
Area of triangle =
Area of rectangle = Length × width
Area of rectangle =
Shaded area = area of rectangle - area of triangle
Shaded area =
Shaded area =
Answer:
Please find attached the graph of the relationship between the gallons, g, and cost, C
The relationship between the cost and number of gallons is cost C = $3.25 × Number of gallons, g
Step-by-step explanation:
The given parameters are;
Number of Gallons, g Cost, C
6 $19.50
22 $71.50
From the given coordinates, we generate the graph using Microsoft Excel, as seen in the attached graph
The given coordinates can be used to find the equation of the relationship in point and slope form as follows;
The slope of the the given coordinates are (71.5 - 19.5)/(22 - 6) = 3.25
The equation of the graph in point and slope form is C - 71.5 = 3.25·(g - 22)
C - 71.5 = 3.25·(g - 22)
C = 3.25·g - 3.25 × 22 + 71.5 = 3.25·g - 0
C = 3.25·g
The relationship between the cost and number of gallons is cost C = $3.25 × Number of gallons, g
From the above equation, we have, that the price per gallon is $3.25
