Answer:
9 1/2 inches
Step-by-step explanation:
The scale of a map is the ratio of map distance to represented distance. This can be used to write a proportion.
__
map distance/represented distance = 1 in/(30 mi) = x/(285 mi)
where x represents the map length of the southern border.
Multiplying by 285 mi, we have ...
x = (285 mi)(1 in)/(30 mi) = 9.5 in
The border is 9.5 inches on the map.
6. If 2 cards are drawn from a standard deck with replacement, find the probability of drawing a face card and an even number.
Answer:
15/169
Step-by-step explanation:
There are 52 cards in a standard deck. Of those 52 cards, 12 are face cards and 20 are even numbered. To find the probabily in this situation, we multiply 12/52 by 20/52. This gives us 240/2704. This can be reduced to 15/169.

A statistical question is a question that can be answered by collecting data that vary.
A statistical question is one that can be answered by collecting data and where there will be variability in that data
The only one that can have a variety of answers is the last one.
A, B, and C are countable and do Not Vary or change in amount they remain the same. There will always be 12 months in a year. 3 wheels on a tricycle and the amount of stripes in the flag will not change. If the question ask something that can change or vary it is a Statistical question. Like for example "How many minutes do 6th grade students typically spend on homework each week?" and “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
A Good Statistical Question Produces Data with Variability
A statistical question is one that requires the collection of data with expected variability in it. The data collected changes in value. You can quantify them. If the data could not be measured, then you have to think it over again.

Irrational numbers: cannot be written as a fraction
Rational numbers: can be written as a fraction
The only option that contains a fraction, is C
Hope this helps!
Option C
Solution:Rational numbers can be expressed as a fraction in the form [tex]\displaystyle\frac{p}{q}[/tex], where p is the numerator and q is the denominator.Now, which numbers can and cannot be expressed as a fraction?First of all, can we express [tex]\sqrt{12}[/tex] as a fraction? No, it's a surd.Can we express [tex]\pi[/tex] as a fraction? No. Remember, pi is irrational. It has an infinite number of digits after the decimal point (same with √12)Can we express [tex]-\displaystyle\frac{3}{7}[/tex] as a fraction? Sure. What's more, it's already a fraction.Can we express √7 as a fraction? No. It's also irrational, like √12 and π.Hope it helps.

A quadratic model would be the most appropriate model for the given data set.
What is a quadratic model?A quadratic model can be defined as a mathematical model which represents a quadratic equation with a single variable of degree 2.
Aso, a quadratic model is mainly symmetrical because the relationship between its variables when plotted on a graph forms a parabola.
In this scenario, the value of the graph at y(1) is equal to y(2) and y(0) is approximately equal to y(3) as shown in the image attached below, which simply means it is symmetrical about this axis.

The graph of f(x) = -x2 - 2x + 8 is shown. Which of the following describes all solutions for f(x)?
O(x -x2 - 2x + 8) for all real numbers
O(-4,0), (-1,9), (0, 8), (2.0)
O(-4.0), (2,0)
O(x, y) for all real numbers
Answer:
[tex]f(x) = -x^2 - 2x + 8[/tex]
y-intercept is when x = 0:
[tex]\implies f(0) = -(0)^2 - 2(0) + 8=8[/tex]
So the y-intercept is (0, 8)
x-intercepts are when f(x) = 0:
[tex]\implies f(x)=0[/tex]
[tex]\implies -x^2 - 2x + 8=0[/tex]
[tex]\implies x^2 + 2x - 8=0[/tex]
[tex]\implies x^2 - 2x + 4x - 8=0[/tex]
[tex]\implies x(x - 2) + 4(x-2)=0[/tex]
[tex]\implies (x+4)(x - 2)=0[/tex]
Therefore:
[tex]\implies (x+4)=0 \implies x=-4[/tex]
[tex]\implies (x-2)=0 \implies x=2[/tex]
So the x-intercepts are (-4, 0) and (2, 0)
The vertex is the turning point of the parabola. The x-value of the vertex is the x-value between the 2 zeros (x-intercepts).
Therefore, the x-value of the vertex is [tex]\sf \dfrac{x_1+x_2}{2}=\dfrac{-4+2}{2}=-1[/tex]
Substituting x = -1 into the function:
[tex]\implies f(-1) = -(-1)^2 - 2(-1) + 8=9[/tex]
So the vertex is (-1, 9)
The domain is the input values, so x = all real numbers.
The range is the output values, so the range is [tex]f(x)\leq 9[/tex]
Therefore, (-4, 0), (-1, 9), (0, 8) and (2, 0) are solutions of the function, HOWEVER they are not ALL the solutions.
All solutions of the function are:
[tex](x, -x^2 - 2x + 8)[/tex] for all real numbers of x

Which values of m and b will create a system of equations with no solution? choose 1 options.
Answer:
The graph of a linear equation is a straight line. The "solution" to a system of two linear equations is the point where the two lines cross. If the two lines are parallel, they never cross; hence parallel lines have no solution. Two lines are parallel if they have the same slope (the m value in y = mx+b). One of your equations is y = -2x + (you left the y-intercept out). The slope is -2. So any line with a slope of m = -2 will be parallel to this line and will not cross it. The second line also needs a different value of b, the y-intercept. Otherwise it is the same line and every point is a solution. So if your equation is:
y = -2x + 1
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.

Step-by-step explanation:
triangles angles should all add up to 180.
so, if you do 68+51 it should equal 119
then you will do 180-119 which gives you 61.

Step-by-step explanation:
I added the current angles together to get 119 and then subtracted 180 from it and got 61.
Number of Handshakes If eight people greet each other at a meeting by shaking hands with one another, how many handshakes take place?
The number of handshake that took place is 28.
In any situation where order of an outcome does not matter, mathematical combination (C) are use calculate the total outcomes of an event.
8 people are to shake each other once. The concept to be use to derive the number of hands that took place is Combination.
The formulae of Combination for this Scenario is n(n-1)/2n(n−1)/2 .
The number of people (n) is 8.
\begin{gathered}Total handshake = n(n-1)/2\\Total handshake = 8 * (8-1)/2\\Total handshake = 8 * 7/2\\Total handshake = 56/2\\Total handshake = 28\end{gathered}Totalhandshake=n(n−1)/2Totalhandshake=8∗(8−1)/2Totalhandshake=8∗7/2Totalhandshake=56/2Totalhandshake=28
In conclusion, the number of handshake that took place is 28.

Solve (2x + 1) (2x + 6) - 7(x - 2) = 4(x + 1)(x - 1)-9x
Answer:
x is equal to -34/16
Step-by-step explanation:
Hey there!
In order to solve for x, we need to first simplify everything
After simplifying, it will look like this:
[tex](4x^2+14x+16)-7x+14=4x^2-4-9x[/tex]
Now you can simplify by combining like terms
[tex]4x^2+7x+30=4x^2-9x-4[/tex]
You can cross out [tex]4x^2[/tex] from both sides and then simplify even more by again combining like terms
[tex]16x+34=0\\16x=-34\\x=-34/16[/tex]
So x is equal to -34/16
To solve the given equation, let's simplify and expand both sides:
[tex]\displaystyle\sf (2x+1)(2x+6)-7(x-2)=4(x+1)(x-1)-9x[/tex]
Expanding the brackets:
[tex]\displaystyle\sf (4x^{2}+13x+6)-7x+14=4(x^{2}-1)-9x[/tex]
Simplifying further:
[tex]\displaystyle\sf 4x^{2}+13x+6-7x+14=4x^{2}-4-9x[/tex]
Combining like terms:
[tex]\displaystyle\sf 4x^{2}+6x+20=4x^{2}-9x-4[/tex]
Subtracting [tex]\displaystyle\sf 4x^{2}[/tex] from both sides:
[tex]\displaystyle\sf 6x+20=-9x-4[/tex]
Bringing all the variables to one side and the constants to the other side:
[tex]\displaystyle\sf 6x+9x=-4-20[/tex]
[tex]\displaystyle\sf 15x=-24[/tex]
Dividing both sides by [tex]\displaystyle\sf 15[/tex] to solve for [tex]\displaystyle\sf x[/tex]:
[tex]\displaystyle\sf x=-\frac{24}{15}[/tex]
Simplifying the fraction:
[tex]\displaystyle\sf x=-\frac{8}{5}[/tex]
Therefore, the solution to the equation is [tex]\displaystyle\sf x=-\frac{8}{5}[/tex].

Find the volume please help I don't understand.
By dividing the figure into a rectangular prism and a pyramid, we will see that the total volume is 2,400 ft^3
How to find the volume?
We can divide the given figure into two simpler ones.
A rectangular prism of 20 ft by 10 ft by 10 ft, whose volume is the product of these dimensions:
V = 20ft*10ft*10ft = 2,000 ft^3
And a pyramid of 4 sides, with a height of 6ft and a base of 20ft by 10ft, and we know that the volume of the pyramid is one-third of the product between the base and the height.
V' = (1/3)*6ft*(20ft*10ft) = 400ft^3
Then the total volume of the given figure is:
volume = V + V' = 2,000ft^3 + 400ft^3 = 2,400 ft^3
