Since the dimension of the scale model is fourth of dimensions of the room, divide by 4 the given dimensions.
new dimensions:
= 18 ft / 4 = 9/2 ft
= 16 ft / 4 = 4 ft
The area is calculated by multiplying the dimensions,
Area = (9/2 ft)(4 ft) = 18 ft²
Therefore, the area of the scale model is equal to 18 ft².

Answer:
2440
Step-by-step explanation:
The difference in fixed costs is ...
37815 -16465 = 21350
The difference in variable costs is ...
20.50 -11.75 = 8.75 . . . . per book
Then the number of books that must be produced for the difference in variable costs to be equal to the difference in fixed costs is ...
21350/8.75 = 2440
For production of 2440 books, the costs of the two methods will be the same.
_____
<em>Additional comment</em>
You can write expressions for total cost of each production method. When you set them equal and solve for the number of books, you find the math you end up doing is the same as that shown above.
Answer:
Step-by-step explanation:
take two points to find the equation:
(0,4),(-2,0)
y= 2x+4
domain is where the equation is defined ( x inputs)
Range is the set of values that correspond with the domain(y outputs)
the domain and the range are all real number
domain(-∞,∞) , range (-∞,∞)
Factor:
5x^3 + 320
Answer when factored:
= 5(x + 4)(x^2 - 4x + 16)
Hope that helps!!!
