(0.8a+0.4b)^2= (0.8a+0.4b) *(0.8a+0.4b)
=
0.64 a^2 + 0.32 ab +0.32ab + 0.16 b^2=
0.64 a^2 + 0.64ab + 0.16 b^2
second
(0.8a-0.4b)^2+1.28ab
= 0.64 a^2 - 0.64ab +0.16 b^2 + 1.28ab
= 0.64 a^2 + 0.64ab + 0.16 b^2
since the first (left parameters ) equals the second(right side parameters)

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].

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.

Answer:
These triangles cannot be proven congruent
Step-by-step explanation:
If all sides and angles of a triangle is congruent to the corresponding sides and angles of another triangle, both triangles are congruent to each other.
This means, they have the same shape and size.
Invariably, knowing just the angles of two triangles are congruent to each other, is not enough to prove that the two triangles are congruent to each other.
Two triangles might have the same angle measure but different size lengths. This means they can have the same shape but different size.
With the information given in the diagram, we can only say that both triangles are similar to each other. However, we cannot prove they are congruent to each other.
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

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

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

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.

The price of a 7-minute phone call is $2.45. What is the price of an 18 -minute phone call?
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ price \ of \ a\ 18 \ min \ call \ is \ \$ \ . }}}[/tex]
Step-by-step explanation:According to Question ,The price of a 7-minute phone call is $2.45 . And we need to find the price of a18 minute phone call . So we will use unitary method here ,
[tex]\implies\bf Cost \ of \ 7 \ min. \ phone \ call \ is\ \$ \ 2.45 . \\\\\implies \bf Cost \ of \ 1 \ min. \ phone \ call \ will \ be \ \dfrac{\$ 2.45}{7} \\\\\implies \bf Cost \ of \ 18 \ min. \ phone \ call \ will \ be \ \dfrac{\$ 2.45}{7} \times 18 = \red{\$ 6.3 } [/tex]
Hence the cost of 18 minutes call is $ 6.3 .Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the cost also increases.

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
