Suppose that a factory manufactures only tables and chairs and that the profit on one chair is $15 and on the table is $20. Each chair requires 1 large piece and 2 small pieces. Each table requires 2 large pieces and 2 small pieces (see Figure 1 below). Finally, suppose that you have only 6 large pieces and 8 small pieces. How many chairs and how many tables should you build to maximize profit? Write a system of equations using inequalities and constraints
Answer:
The data we have is:
Profit per chair = $15
Profit per table = $20
Chair needs: 1 large pice, 2 small pieces.
Table needs: 2 large pieces, 2 small pieces.
You have 6 large pieces and 8 small pieces, and you want to maximize the profit.
Let's define:
T = # of tables
C = # of chairs.
Total profit:
P = C*$15 + M*$20
The number of chairs that you can make is given by:
0 ≤ C ≤ 4
If you make 4 chairs, the profit is:
P = 4*$15 = $60
And there will be 2 large pieces left.
Now for the tables.
0 ≤ T ≤ 3
If you make 4 tables, the profit will be:
P = 3*$20 = $60 (same as before)
And there will be two small pieces left.
Then we want to use a medium number of tables and chairs, we can not use the maximum for any of those, the first thing we should try is:
we ideally would want to use all the pieces that we have.
8 small, 6 large:
Then we can make:
2 tables: we use 4 large pieces and 4 small pieces.
T = 2
And we have left 2 large pieces and 4 small pieces.
The leftover is enough to make two chairs.
C = 2.
In this case, where we used all our materials, the profit will be:
P = 2*$15 + 2*$20 = $30 + $40 = $70
The profit is maximized when we make 2 tables and two chairs.
how to solve a variable?
Answer:
In mathematics, to solve an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.

48 dollars (0.55)
48 dollars (55)
48 dollars (0.55) + 48 dollars
48 dollars (55) = 48 dollars
Answer:
The answer is 48(0.55) x 48
Step-by-step explanation:
wholesale $48 and sold at 55% which is the same as 0.55 then multiply wholesale by percent

16. For the the equation 4x+8 9x+3.
Explain the steps that were used to solve the equation below
4X + 8 9X+3
4x + 5 = 9x
5 = 5x
1 = X
4X + 8 9X+3 (this is the equation, nothing to explain in this step)
4x + 5 = 9x (you combine or subtract the like terms, 8 - 3 = 5)
5 = 5x (you do 9x - 4x = 5x, subtracting the like terms)
1 = X (your answer after dividing 5 from both sides)
A manufacturer of widgets finds that the production cost, C, in dollars per unit is a function of the number of widgets produced. The selling price, S, of each widget in dollars is a function of the production cost per unit.
C(x) = –0.1x2 + 100
S(C) = 1.4C
What is the selling price per widget as a function of the number of widgets produced, and what should the selling price be if 15 widgets are produced?
A.C(S(x)) = –0.196x^2 + 100; $108.64
B.C(S(x)) = –0.196x^2 + 100; $55.90
C.S(C(x)) = –0.14x^2 + 140; $144.41
D.S(C(x)) = –0.14x^2 + 140; $108.50
This is a question on composite functions.
Answer:
S(C(x)) = –0.14x2 + 140; $108.50 - On edgenuity the answer is D.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The value of the function at 870, the local maximum, is
= -0.02(870)2 + 34.80(870) - 4700
= -0.02(756900) + 30276 - 4700
= -15138 + 25576
= 10438
So the vertex is (870, 10438)
The cost t the company to produce 870 widgets is
C(870) = 4700 + 5.20(870) = 4700 + 4524 = 9224
So, the cost of the widgets plus the profit must be equal to the total sales, which is divided by the number of widgets reveal their individual price.
(10438 + 9224)/870 = 19662/870 = $22.60
P(x) = 7700
- 0.02x2 + 34.80x - 4700 = 7700
-0.02x2 + 34.80x -12400 = 0
x = {-34.80 ± √[(34.80)2 - 4(-0.02)(-12400)]}/2(-0.02)
x = [-34.80 ± √(1211.04 - 992)]/(-0.04)
x = (-34.80 ± √219.04)/(-0.04)
x = (-34.80 ± 14.8)/(-0.04)
x = 870 ± 370
so, $7700 in profits will be earned at either 500 widgets or 1240 widgets

Which is defined using the undefined terms point and line?
A) angle
B) circle
C) parallel lines
D) ray
Answer:
i would say circle cause there no evan lines angles or points in it
Step-by-step explanation:
The object which is defined using undefined terms of points and lines is option D)
D) Ray
Reason for electing the above option is as follows;
Undefined terms are terms that are not required to be given formal definition in them selves and they include the terms set, plane, line, and point
A point is a dimensionless marker of position and it is indicated in geometry by a capital letter. In geometry, a point is the most elementary entity
A line is an infinitely long and straight geometric object that is defined and named by any two points located on it
A ray is a subset of a line that extends long straight infinitely in one direction, and has a starting point
Therefore, the geometrical object defined by a point and a line is a ray and the correct option is option D)

The length of an American flag is 1.8 times its width. What is the
width of the flag?
length=10
Answer:
5.56 or put [tex](5 \frac{5}{9})[/tex]
Step-by-step explanation:
length = 1.8* width
if the length is 10 , we solve like this :
10 = 1.8* width
10/1.8 = width
width = 5.555.... [tex](5 \frac{5}{9})[/tex]
