Writing an equation and drawing its graph to model a real-world situation ​
Mariana [72]

Answer:

A = B + 15

Step-by-step explanation:

Let Diane sold B books in one hour,

Additional earning by selling 1 book = 1$

Additional earning by selling B books = Number of books sold × Additional earning by selling one book

= B × ($1.00)

= $B

Fixed earning of Diane in one hour of part time = $15

Total earnings = B + 15

A = B + 15

Table to find the input-output values for the graph,

A      15      16        17      18

B       0        1          2       3

Now we can plot the points on the graph.

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so very much!
Romashka [77]

Answer:

66.3 sq ft

Step-by-step explanation:

Here's the plan: we'll find the area of the circle then subtract the area of the triangle.

Area of circle:

A = pi•r^2

= pi•6^2

= 3.14•36

~= 113.04

Area of triangle:

A = 1/2bh

= 1/2(10.39)(9)

The height is the 6+3 in the image.

~= 46.755

Subtract to find

Area of Shaded:

113.04 - 46.755

= 66.285

Round to nearest tenth.

~= 66.3 sq ft
