Ok,
Since we have that the price of the pants is $2995 and that represents the 100%.
In order to determine the total value since we get a 10% discount, we do as follows:
[tex]2995\to100\text{ \& x}\to10[/tex]We determine the 10%, multiplying the percentage we want to know (10%) times the total ammount of money the pants cost ($2995) and then divide by the total percentage (100%):
[tex]x=\frac{2995\cdot10}{100}\Rightarrow x=299.5[/tex]x represents our 10% and so we extract x from the total:
[tex]T=2995-299.5\Rightarrow T=2695.5[/tex]Therefore the total price to pay is $2695.5
For a function f(x), you know that f(3) = -8 and f(4) = 3. One zero of f(x) would be located between x= and x=
Problem Statement
The question tells us that f(3) = -8 and f(4) = 3 and we are asked to find where one of the zeros of the function.
Solution
The function f(x) moves from negative to positive when moves from x = 3 to x = 4. This means that the value of f(x) must cross the x-axis between these two values of x.
Answer
Thus, one zero of the function lies between X = 3 and X = 4

You're going to the mall with your friendsand you have $200 to spend from yourrecent birthday money. You discover astore that has all jeans for $25 and alldresses for $50. You really, really want totake home 6 items of clothing because you"need" that many new things. How manypairs of jeans and how many dresses youcan buy so you use the whole $200 (taxnot included)?
Given that:
- You have $200 to spend.
- The store sells all jeans for $25 and all dresses for $50.
- You want to take home 6 items of clothing.
Let be "j" the number of jeans and "d" the number of dresses you can buy so you use the whole $200 (not including the tax).
Set up this System of Equations using the data provided in the exercise:
[tex]\begin{cases}j+d=6{} \\ 25j+50d={200}\end{cases}[/tex]You can follow these steps in order to solve the System of Equations using the Elimination Method:
1. You can multiply the first equation by -25:
[tex]\begin{cases}-25j-25d={-150} \\ 25j+50d={200}\end{cases}[/tex]2. Add the equations:
[tex]\begin{gathered} \begin{cases}-25j-25d={-150} \\ 25j+50d={200}\end{cases} \\ ------------ \\ 0j+25d=50 \\ 25d=50 \end{gathered}[/tex]3. Solve for "d":
[tex]\begin{gathered} d=\frac{50}{25} \\ \\ d=2 \end{gathered}[/tex]4. Substitute the value of "d" into the first original equation and solve for "j":
[tex]\begin{gathered} j+(2)=6 \\ j=6-2 \\ j=4 \end{gathered}[/tex]Hence, the answer is: You can buy 2 dresses and 4 jeans.

Andy is designing a dice tray in the shape of a rectangular prism to use during a role-playing game. The tray needs to be three centimeters highand have a volume of 252 cubic centimeters in order for the dice to roll properly. The length of the tray should be five centimeters longer thanits width.The volume of a rectangular prism is found using the formula V= / w- h, where / is the length, w is the width, and h is the height.
Explanation
The volume of a rectangular prism is given by
[tex]v=length\times breadth\times height[/tex]We have the information:
h =3cm
v=252 cm³
If the width is x
And the length is 5cm longer than the width
L =5+x
Then, we will have
[tex]volume=252=l\times w\times h=(5+x)(x)(3)[/tex]Thus, we will have
[tex]\begin{gathered} 252=3x(5+x) \\ 252=15x+3x^2 \\ 3x^2+15x-252=0 \end{gathered}[/tex]Simplifying further
[tex]x^2+5x-84=0[/tex]Thus, the equation that models the tray will be
[tex]x^2+5x=84[/tex]Part B
To check if a with of 7.5 is possible, we will put x = 7.5c and check if the equation holds true
[tex](7.5)^2+5(3.5)=93.75[/tex]since
[tex]\begin{gathered} 93.75\ne84 \\ The\text{ is false} \\ \end{gathered}[/tex]Therefore, the answer is NO.
It is not possible for the width to be 7.5cm

Is the vertex of the quadratic function below a maximum or minimum?
A quadratic equation is of the form below:
[tex]ax^2+bx+c=y[/tex]The vertex of the quadratic equation is the value of y where the curve cut the y-axis.
To find the vertex, we would first first find the x-coordinate of the equation using
[tex]x=-\frac{b}{2a}[/tex]To find the vertex, we would substitute for x in the equation to get y.
Given the quadratic function below
[tex]f(x)=-3x^2-4x+7[/tex]It can be observed that
[tex]a=-3;b=-4,c=7[/tex]The x-coordinate of the vertex is as shown below:
[tex]\begin{gathered} x=-\frac{b}{2a} \\ x=\frac{--4}{2(-3)} \\ x=\frac{4}{-6} \\ x=-\frac{2}{3} \end{gathered}[/tex]The vertex would be
[tex]\begin{gathered} f(-\frac{2}{3})=-3(-\frac{2}{3})^2-4(-\frac{2}{3})+7 \\ f(-\frac{2}{3})=-3(\frac{4}{9})+\frac{8}{3}+7 \\ f(-\frac{2}{3})=-\frac{4}{3}+\frac{8}{3}+7 \\ f(-\frac{2}{3})=\frac{-4+8}{3}+7 \\ f(-\frac{2}{3})=\frac{4}{3}+7 \\ f(-\frac{2}{3})=1\frac{1}{3}+7=8\frac{1}{3}=\frac{25}{3} \end{gathered}[/tex]Hence, the vertex of the quadratic function is (-2/3,25/3)
It should be noted that when a is positive, the quadratic graph opens upward and the vertex is minimum but when a is negative, the quadratic curve opens downward, and the vertex would be maximum
The graph of the quafratic function given is shown below

The speed in kilometers per second is 28.8 kilometers per second
The distance traveled in 15 seconds is 432 kilometers
Converting speed to kilometers per second and distanceFrom the question, we are to convert the speed to kilometers per second
From the given information,
The speed of the Earth is approximately 18 miles per second
Now, we will convert 18 miles to kilometers
Also, from the given information,
We are to assume that 1 mile is equal to 1.6 kilometers
If 1 mile = 1.6 kilometers
Then,
18 miles = 18 × 1.6 kilometers

The data set below provides the monthly rent (in dollars) paid by 7 tenants.990, 879, 940, 1010,950, 920, 1430Suppose the rent for one of the tenants changes from $1430 to $1115.What is the mean before the rent change?What is the mean after the change?
To solve this question, we need to find the mean for both cases. The mean is given by summing the given values and then dividing them by the number of values (or given cases).
We have that, before the rent chance, we have the following monthly rent (in dollars):
990, 879, 940, 1010,950, 920, 1430
There are seven (7) values. Then, the mean, in this case, is:
[tex]m_{\text{before}}=\frac{990+879+940+1010+950+920+1430}{7}=\frac{7119}{7}\Rightarrow m=1017[/tex]Therefore, the mean, in this case, is equal to $1017.
Now, we have that the rent change for the one with $1430 to $1115, now the values are:
990, 879, 940, 1010,950, 920, 1115.
We can proceed as before to obtain the mean:
[tex]m_{\text{after}}=\frac{990+879+940+1010+950+920+1115}{7}=\frac{6804}{7}\Rightarrow m_{after}=972[/tex]Thus, the mean after the change is equal to $972.
In summary, we have that:
• The mean before the rent change is equal to $1017
,• The mean after the rent change is equal to $972.
