Answer:
Arithmetic content = 300 pages
Geometric content = 180 pages
Step-by-step explanation:
Arithmetic : Geometry = 5 : 3
Total pages of book = 480
How much of each type of content will be needed to make a book of 480 pages?
Total ratio = arithmetic + geometric
= 5 + 3
= 8
Arithmetic content = 5 / 8 × 480
= 0.625 × 480
= 300
Arithmetic content = 300 pages
Geometric content = 3 / 8 × 480
= 0.375 × 480
= 180
Geometric content = 180 pages

Answer:
The required model is
60 pounds of concrete each bag make.
Step-by-step explanation:Consider the provided information.
Let the number of concrete bags are used is represented by y.
Part (A)
3.5 bags of concrete mix for a new set of stairs and 2.25 bags of concrete mix for a garden wall.
This can be written as:
Timothy mixed 345 pounds of concrete in all.
Therefore,
Hence, the required model is
Part (B) Solve for y. How many pounds of concrete does each bag make?
Consider the above equation.
Solve the equation for y as shown.
Add the like terms.
Divide both the sides by 5.75
Hence, 60 pounds of concrete each bag make.
