ok so
42≤0.45x+0.60y
x=pounds of finnishing nails
y=pounds common nails
when x+y≥30
now lets solve for y
y=-x+30
lets plug this in to the formula
42≤0.45x+0.6(−x+30)
x≤−160
nowing this lets plug in for x
x+y≥30
-160+y≥30
y≥190

Explain how the applications of inventory management for fixed quantities differ from those for fixed time periods. Give specific instances in which you would use a fixed time period model rather than a fixed quantity model. Provide real-world examples.
Answer:
The main difference between the fixed quantity and fixed time period is that the fixed quantity makes it mandatory for a fixed number of items to be ordered every time an order is made, while the fixed time period has a fixed period orders are received before the next order period.
Step-by-step explanation:
The fixed quantity model is adopted by producers of a product to maintain a package type and also to maximize the profit derived from sales. For example is when ordering or buying eggs from a store, the buyer cannot purchase five eggs since it is packaged in a dozen (12), and so must buy the whole package.
The fixed time model uses time intervals to receive and accumulate orders before delivery is made for every order interval.

Use quadratic regression to find the
equation for the parabola going
through these 3 points.
(2, 19) (6, 99) (-1, 1)
y=[?]^2+[?]x+[?]
Answer:
The standard form of the parabola is
y = 2 x² + 4 x + 3
Step-by-step explanation:
Step(i):-
The standard form of the parabola
y = a x² + b x + c ...(i)
The equation for the parabola is passing through the point (2 , 19 )
19 = 4a + 2b +c ...(ii)
The equation for the parabola is passing through the point (6 , 99 )
99 = 36a + 6b +c ...(iii)
The equation for the parabola is passing through the point (-1,1) )
1 = a - b + c ...(iv)
step(ii):-
subtracting (ii) and (iii) , we get
8a + b = 20 ...(a)
Subtracting (iii) and (iv) , we get
5a + b = 14 ...(b)
solving (a) and (b) , we get
subtracting (a) and (b) , we get
8a + b-( 5a + b ) = 20 - 14
3 a = 6
a = 2
substitute a=2 in equation (a) , we get
8a + b = 20
8(2) + b = 20
b =20 -16
b = 4
Substitute a= 2 ,b = 4 in equation (ii) , we get
19 = 4a + 2b +c
19 = 8 + 8 + C
c = 19 -16 = 3
Final answer:-
The standard form of the parabola is
y = 2 x² + 4 x + 3

Given:
A committee of 6 members is to be chose from the 100 members of the U.S. senate.
To find:
The number of ways to form a committee.
Solution:
We have,
Total number of members = 100
Number of members needs to selected of committee = 6
Number of ways to select r items from total n items is
[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
Number of ways to select 6 members from total 100 members is
[tex]^{100}C_6=\dfrac{100!}{6!(100-6)!}[/tex]
[tex]^{100}C_6=\dfrac{100\times 99\times 98\times 97\times 96\times 95\times 94!}{6\times 5\times 4\times 3\times 2\times 1\times 94!}[/tex]
[tex]^{100}C_6=\dfrac{100\times 99\times 98\times 97\times 96\times 95}{6\times 5\times 4\times 3\times 2\times 1}[/tex]
[tex]^{100}C_6=1192052400[/tex]
Therefore, the total number of ways to form a committee is [tex]^{100}C_6[/tex], i.e., equal to [tex]1192052400[/tex].

To Find :
The value of x.
Solution :
[tex](\dfrac{X}{10}\times 0.24 )- \dfrac{15.5}{7.5} = 9\\\\(\dfrac{X}{10}\times 0.24 ) = 9 + \dfrac{15.5}{7.5}\\\\(\dfrac{X}{10}\times 0.24 ) = \dfrac{(9\times 7.5 )+ 15.5}{7.5}\\\\(\dfrac{X}{10}\times 0.24 ) = \dfrac{83}{7.5}\\\\X = \dfrac{83\times 10}{7.5\times 0.24}\\\\X = 461.11[/tex]
Therefore, the value of X is 461.11 .

8r-5>75. helpppppppp
Answer and Step-by-step explanation:
In this inequality, we are solving for r. Just think of this as a normal equation, and worry about the sign at the end.
First, add 5 to both sides.
8r > 80
Now divide by 8 to both sides.
r > 10
So, r is greater than 10.
[ If the inequality had a negative number being divided, then the sign would flip.
For example:
-2x > 4
To solve this one, you would divide by -2 to both sides. Then, you would flip the sign.
x < 2 ]

Naty bought a dress for $24.95 and a skirt for $14.95.
The sales clerk said the total cost including 9.5% sales
tax was 49.40. Below are the steps the clerk completed.
Step 1: 24.95 + 14.95 = 39.90
Step 2: 39.90 +9.5 = 49.40
Are the clerk's steps correct? If she is incorrect, identify
her mistake and explain her error. Explain in writing how
to accurately calculate the sales tax, total cost, and state
the correct total. (Round final answer to the nearest
hundredth)
Answer:
Total items = $39.90
Sales tax amount = $3.7905
Total cost = $43.691
The clerk's error is using 9.5 as sales tax amount instead of finding 9.5% of the total items
Step-by-step explanation:
Dress = $24.95
Skirt = $14.95
steps the clerk completed.
Step 1: 24.95 + 14.95 = 39.90
Step 2: 39.90 +9.5 = 49.40
Correct steps:
Total items = dress + skirt
= $24.95 + $14.95
= $39.90
Sales tax = 9.5%
Sales tax amount = 9.5% of total
= 9.5/100 × $39.90
= 0.095 × 39.90
= $3.7905
Total cost = Total + sales tax amount
= $39.90 + $3.7905
= $43.6905
To the nearest hundredth
= $43.691
Sales tax is the amount of money imposed by government on the sales of some items
Total cost is the cost of all items including sales tax

which of the following best describes 4^2/3? a. sq root of 16, b. cube root of 4, c. sq root of four, d. cube root of 16
Answer: D) cube root of 16
================================================
Explanation:
The rule we use is
[tex]x^{m/n} = \sqrt[n]{x^m}[/tex]
In this case, x = 4, m = 2 and n = 3.
So,
[tex]x^{m/n} = \sqrt[n]{x^m}\\\\\\4^{2/3} = \sqrt[3]{4^2}\\\\\\4^{2/3} = \sqrt[3]{16}\\\\\\[/tex]
Showing that the original expression turns into the cube root of 16.

Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
m = -1

Figure ABCD has vertices A(- 5, 2) , B(4, 2) , C(4, - 5) , and D(- 5, - 3) . What is the area of Figure ABCD? 9 square units 45 square units 54 square units 122 square units
Answer:
54 square units
Step-by-step explanation:
ABCD = ABED + CED
A and B have same y coordinate
A and D have same x coordinate
AB ⊥ AD
AB = 4 - (-5) = 9
AD = 2 - (-3) = 5
EC = BC - AD = (2 + 5) - 5 = 2
ABCD = 9 x 5 + 1/2 (9 x 2) = 45 + 9 = 54

What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
The value of x = - 87
The value of y = 34
The equation x + y is calculated by substituting the values of x and y in the equation ,
Therefore , x + y = ( - 87 ) + 34
= -53
Hence , the value of x + y is equal to - 53
