Answer:
12.8 grams per 1 package
102.4 grams per 8 packages
128 grams per 10 packages
Step-by-step explanation:
we can take
25.6 ÷ 2
to get the unit rate (number of grams per 1 package)
25.6 ÷ 2 = 12.8
12.8 grams per 1 package
multiply 12.8 by 8 to get the amount of grams per 8 packages
12.8 * 8 = 102.4
102.4 grams per 8 packages
we can set up a proportion to find the number of packages for 128 grams
let p = number of packages
12.8/1 = 128/p
12.8 = 128/p
multiply by "p" on both sides to get rid of the "p" in the denominator
12.8*p = (128/p )* p
12.8p = 128
divide by 12.8 on both sides to isolate "p"
12.8p = 128
÷12.8 ÷12.8
p = 10
128 grams per 10 packages

The area of a new wctabfle is 28m^2 and the length of the rectangle is 1m more than double the width. Find the dimensions
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Represent the sides of the rectangle
Let the length be represented by l
Let the width be represented by w
STEP 2: Interpret the statements in the question.
[tex]\begin{gathered} length\text{ is 1m more than the double of the width:} \\ double\text{ of the width}\Rightarrow2w \\ 1m\text{ more than the double}\Rightarrow2w+1 \\ \therefore l=2w+1 \end{gathered}[/tex]STEP 3: Equate the area of the rectangle to given measure
[tex]\begin{gathered} Area=length\times width \\ length=2w+1,width=w \\ Area=(2w+1)\cdot w=28 \\ By\text{ simplification,} \\ w(2w+1)=28 \end{gathered}[/tex]STEP 4: Solve for the width
[tex]\begin{gathered} w(2w+1)=28 \\ By\text{ expansion,} \\ 2w^2+w=28 \\ Subtract\text{ 28 from both sides} \\ 2w^2+w-28=28-28 \\ 2w^2+w-8=0 \end{gathered}[/tex]STEP 5: Solve the equation using quadratic formula
[tex]quadratic\text{ formula}\Rightarrow\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]From the equation,
[tex]a=2,b=1,c=-28[/tex]By substitution,
[tex]\begin{gathered} w_{1,\:2}=\frac{-1\pm\sqrt{1^2-4\cdot\:2\left(-28\right)}}{2\cdot\:2} \\ \sqrt{1^2-4\times2(-28)}=15 \\ By\text{ substitution,} \\ w_{1,\:2}=\frac{-1\pm \:15}{2\cdot \:2} \\ \mathrm{Separate\:the\:solutions} \\ w_1=\frac{-1+15}{2\cdot \:2},\:w_2=\frac{-1-15}{2\cdot \:2} \\ w=\frac{-1+15}{2\times2}=\frac{14}{4}=\frac{7}{2}=3.5 \\ w=\frac{-1-15}{2\cdot\:2}=\frac{-16}{4}=-4 \end{gathered}[/tex]Since the width cannot be negative, this means that the value of the width is 3.5m
STEP 6: Solve for the length
By substitution into the formula in step 2, we have:

A book store sells used books. Paperback books cost $1.00. Hardback books sell for $5.00. The store sold 100 books and made $260 from the sale, How many paperback books did the store sell?
ANSWER
60 paperback books
EXPLANATION
We have that:
Paperback books sell for $1.00
Hardback books sell for $5.00
The store sold 100 books and made $260.
Let the number of paperback books be x
Let the number of hardback books be y.
This means that:
x + y = 100 _____(1)
and
1 * x + 5 * y = 260
=> x + 5y = 260 ____(2)
We have two simultaneous equations:
x + y = 100 ____(1)
x + 5y = 260 ___(2)
From (1):
x = 100 - y
Put that in (2):
100 - y + 5y = 260
=> 100 + 4y = 260
Collect like terms:
4y = 260 - 100
4y = 160
y = 160 / 4
y = 40 books
This means that:
x = 100 - 40
x = 60 books
Therefore, 60 paperback books were sold.
Ian is a salesperson who sells computers at an electronics store. He makes a base payof $80 each day and then is paid a $5 commission for every computer sale he makes.Make a table of values and then write an equation for P, in terms of x, representingIan's total pay on a day on which he sells x computers.
ANSWER
[tex]P=5x+80[/tex]EXPLANATION
Let the number of computers sold be x.
Let the total pay be P.
We have to find the equation that represents the total pay in terms of the number of computers sold.
The equation that represents the total pay is a linear equation and a linear equation has a general form of:
[tex]y=mx+b[/tex]where m = slope
b = y intercept
To find the slope, we have to apply the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]where (x1, y1) and (x2, y2) are two sets of points from the table.
Let us pick (0, 80) and (3, 95)
Therefore, the slope, m, is:
[tex]\begin{gathered} m=\frac{95-80}{3-0} \\ m=\frac{15}{3} \\ m=5 \end{gathered}[/tex]Now, we apply the point-slope formula to find the equation:
[tex]P-P_1=m(x-x_1)[/tex]Note: P is used in place of y (the dependent variable)
Therefore, we have:
[tex]\begin{gathered} P-80=5(x-0) \\ P-80=5x \\ \Rightarrow P=5x+80 \end{gathered}[/tex]That is the equation that represents the total pay, P.
Solve 3x-9 = 6.A. x = 2B. x=-1C. x = 1D. x = 5
Step 1. The expression that we have is:
[tex]3x-9=6[/tex]And we need to solve for x.
If we are going to solve for x, we need to have the 'x' alone on one side of the equation.
For that, the first step is to add 9 to both sides:
[tex]3x-9+9=6+9[/tex]Step 2. On the left side, -9+9 cancel each other, and on the right side 6+9 is 15:
[tex]3x=15[/tex]Step 3. The next step is to divide both sides by 3:
[tex]\frac{3x}{3}=\frac{15}{3}[/tex]In this way, 3/3 on the left side cancel each other and we are left only with x:
[tex]x=\frac{15}{3}[/tex]And on the right side, 15/3 is equal to 5:
[tex]\boxed{x=5}[/tex]This is shown in option D.
Answer:
D. x=5

Find the domain of the rational function.f(x)=(x−7)/(x+8)
Answer:
[tex](-\infty,-8)\cup(-8,\infty)[/tex]Explanation:
Given the rational function:
[tex]f(x)=\frac{x-7}{x+8}[/tex]The domain of f(x) is the set of the values of x for which the function is defined.
A rational function is undefined when the denominator is 0.
Set the denominator of f(x) equal to 0 in order to find the value(s) of x at which f(x) is undefined.
[tex]\begin{gathered} x+8=0 \\ \implies x=-8 \end{gathered}[/tex]-8 is the excluded value of the domain.
Therefore, the domain of f(x) is:
[tex](-\infty,-8)\cup(-8,\infty)[/tex]
For the function f(x) = x^2 + 3x,a) Find f(-2).b) Is this function linear or quadratic? Justify your answer.c) Will the graph of this function appear as a line or a parabola?
a) Evaluating the function at x= -2 we get:
[tex]f(-2)=(-2)^2+3(-2)=4-6=-2[/tex]b) Notice that the given function has the form:
[tex]y=ax^2+bx+c[/tex]Therefore f(x) is a quadratic function.
c) Since f(x) is a quadratic function its graph is a parabola.
4 The number of cars in 5 different parkinglots are listed below.35, 42, 63, 51, 74What is the mean absolute deviation ofthese listed numbers?
The number of cars in 5 different parking lots are given as data points as follows:
[tex]35\text{ , 42 , 63 , 51 , 74}[/tex]We are to determine the Mean Absolute Deviation ( MAD ). It is a statistical indicator which is used to quantify the variability of data points. We will apply the procedure of determining the ( MAD ) for the given set of data points.
Step 1: Determine the Mean of the data set
We will first determine the mean value of the data points given to us i.e the mean number of cars in a parking lot. The mean is determined by the following formula:
[tex]\mu\text{ = }\sum ^5_{i\mathop=1}\frac{x_i}{N}[/tex]Where,
[tex]\begin{gathered} \mu\colon\text{ Mean} \\ x_i\colon\text{ Number of cars in ith parking lot} \\ N\colon\text{ Total number of parking lots} \end{gathered}[/tex]We will use the above formulation to determine the mean value of the data set:
[tex]\begin{gathered} \mu\text{ = }\frac{35\text{ + 42 + 63 + 51 + 74}}{5} \\ \mu\text{ = }\frac{265}{5} \\ \textcolor{#FF7968}{\mu=}\text{\textcolor{#FF7968}{ 53}} \end{gathered}[/tex]Step 2: Determine the absolute deviation
The term absolute deviation is the difference of each point in the data set from the central tendency ( mean of the data ). We determined the mean in Step 1 for this purpose.
To determine the absolute deviation we will subtract each data point from the mean value calculated above.
[tex]AbsoluteDeviation=|x_i-\mu|[/tex]We will apply the above formulation for each data point as follows:
[tex]\begin{gathered} |\text{ 35 - 53 | , | 42 - 53 | , | 63 - 53 | , | 51 - 53 | , | 74 - 53 |} \\ |\text{ -18 | , | -11 | , | 10 | , | -2 | , | }21\text{ |} \\ \textcolor{#FF7968}{18}\text{\textcolor{#FF7968}{ , 11 , 10 , 2 , 21}} \end{gathered}[/tex]Step 3: Determine the mean of absolute deviation
The final step is determine the mean of absolute deviation of each data point calculated in step 2. Using the same formulation in Step 1 to determine mean we will determine the " Mean Absolute Deviation ( MAD ) " as follows:
[tex]\begin{gathered} \mu_{AD}\text{ = }\frac{18\text{ + 11 + 10 + 2 + 21}}{5} \\ \mu_{AD}\text{ = }\frac{62}{5} \\ \textcolor{#FF7968}{\mu_{AD}}\text{\textcolor{#FF7968}{ = 12.4}} \end{gathered}[/tex]Answer:
[tex]\textcolor{#FF7968}{MAD=12.4}\text{\textcolor{#FF7968}{ }}[/tex]Given the diagram shown, which of the following statements are true.

[in the following write an expression in terms of the given variables that represents the indicated quantity.]the sum of three consecutive integers if the greatest integer is x.the expression for the sum of the three consecutive integers is _________
Answer
Sum of the three consecutive integers = 3x - 3
Explanation:
Find the sum of three consecutive integers
Condition given: Greatest integer should be x
Since, x is the greatest integer, therefore, the other integers should be less than x
The three consecutive integers are: x, x - 1, and x - 2
Sum of the three integers = x + x - 1 + x - 2
Sum = x + x - 1 + x - 2
Collect the like terms
= x + x + x - 1 - 2
Sum = 3x - 3
Therefore, the sum of the three consecutive integers is 3x - 3
