Pretty simple equation, where we need to find the number of books. If it is 2$ each day per book
72/9 = 8$ per day is the late fee paid
So if each book is 2$, then we can assume
8/2 = 4 books
So equation is
“# books = (amount paid)/(days * per day payment)”
You multiply 5 times 10, which gives you 50. This is the length of one side. Since it's a square, all sides are the same length.
Answer: 50cm x 50cm
Answer:
Alright solve for x by simplifying both sides of the equation, then isolating the variable
x = - 13/4 Hope this helps :)

Problem 1
Answers:
- Choice A) Cylinder
- Choice C) Rectangular prism
- Choice D) Rectangular pyramid
Reason:
Refer the diagram below to see how rectangular cross sections are possible. The cross sections are marked in red.
For the rectangular prism, we could have a vertical or horizontal plane. For the cylinder, only a vertical cross section is possible. On the flip side, a rectangular pyramid can only have horizontal rectangular cross sections (which are similar to the base).

Problem 2
Answer: Approximately 73,280.62908 square feet
Explanation:
Calculate the area of the trapezoid. Ignore the small triangle for now.
A = h*(b1+b2)/2
A = 354*(266+158)/2
A = 75,048
Now calculate the area of the triangle we ignored earlier
Before we do this, we'll need to use the pythagorean theorem to find the missing horizontal piece
a^2 + b^2 = c^2
b = sqrt(c^2 - a^2)
b = sqrt(97^2 - 40^2)
b = 88.368546 which is approximate.
Now we can find the area of the small triangle
Area = base*height/2 = 88.368546*40/2 = 1,767.37092
This is to be subtracted from the area of the trapezoid we found earlier.
75,048 - 1,767.37092 = 73,280.62908
Round the result however you need to.
V = V 1 + V 2 + V 3 =
= 4² · 8 + 4² · 12 + 4² ·8 =
= 4² · ( 8 + 12 + 8 ) =
= 16 · 28 = 448
Answer:
The volume of the composite figure is 448 yd³.
