The scale of the map is 1 square inches = [tex]10^{13}[/tex] square inches.
Given that:-
Area of the desert = 25,000 square miles
Area of the desert in the map = 10 square inches
We have to find the scale of the map.
We know that,
1 mile = 63360 inches
Hence, conversion of square miles to square inches:-
1 mile * 1 mile = 63360 inches *63360 inches
1 square mile = 4,01,44,89,600 square inches
25,000 square miles = 40144893600*25000 = 10,03,62,24,00,00,000 square inches =[tex]10.036224 *10^{13}[/tex] ≈ [tex]10*10^{13}[/tex] square inches.
Now, we can say that [tex]10*10^{13}[/tex] square inches is scaled to 10 square inches.
Hence, the scale of the map is :-
1 square inches = [tex]10^{13}[/tex] square inches.

3. What is the simple interest and the amount in the account if you invested$175.00 for 90 days at 8%?
The formula for the simple interest I after an amount P is invested for period t at a simple interest rate r is:
[tex]I=P\cdot r\cdot t[/tex]In this problem, the simple interest annual rate is 8% = 0.08. But the period t of the investment is
t = 90 days = 3 months = (12/4) months = (1/4) year
And the rate is:
[tex]r=\frac{0.08}{\text{year}}=\frac{\frac{0.08}{4}}{\frac{\text{year}}{4}}=\frac{0.02}{t}[/tex]Then, using P = 175, the interest, in dollars, is:
[tex]I=175\cdot\frac{0.02}{t}\cdot t=175\cdot0.02=3.5[/tex]And the amount A, in dollars, in the account after that period is:

Speed (ft/sec), s: 4603 4748 4960 5049 5095 5062
A function which models the data in the given table is y = 3848.2x^0.054. Also, an approximate speed of sound when the water temperature is 100°F is equal to 4935 ft/sec.
What is a line of best fit?A line of best fit can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.
In this scenario, the temperature of water would be plotted on the x-axis of the scatter plot while the speed of sound would be plotted on the y-axis of the scatter plot.
By critically observing the scatter plot (see attachment) which models the data in the given table, we can reasonably and logically deduce that a function for the line of best fit is given by:
y = 3848.2x^0.054
Next, we would determine the speed of sound when the water temperature is 100°F as follows:
y = 3848.2x^0.054
y = 3848.2 × (100)^0.054
y = 3848.2 × 1.2823
y = 4934.55 ≈ 4935 ft/sec.

Steps for graphing a quadratic equation from vortex form
Graphing a Quadratic Equation
Let's take as an example the function:
[tex]y=-2\mleft(x-3\mright)^2+5[/tex]The vertex form of a quadratic function is:
[tex]y=a\mleft(x-h\mright)^2+k[/tex]Where a is the leading coefficient and (h,k) is the vertex.
If a is positive, the function is concave up, if negative the function is concave down.
The first step is to obtain the parameters by comparing the given equation with the general equation.
Thus, we have: a = -2. Vertex = (3,5)
Now we locate the vertex in the coordinate plane and draw the parabola opening down.
For more precision, we can substitute some points around the vertex, like for example:
x={1,2,4,5}
We get the y-coordinates:
y={-3,3,3,-3}
Then we plot the graph as follows:

Given that the person has a master's degree, the probability that a randomly chosen person was a business major.
The probability that the person has a business major is going to be represented by: p(B | M)
What is probability?This is the concept that is used in statistical and mathematical analysis to refer to the likelihood and the chances of something happening. That is the likelihood of an event occurring.
We have to define M as the event that the person that has been chosen randomly has a masters degree.
We have to define B as the event that the person that has being chosen randomly has a business major.
Given that the person has a master's degree, the probability that a randomly chosen person was a business major is given as p(B|M)
This would be the conditional probability that is written in the form of
p(B|M) = P(B and M) / P(M)

Interest rate (r) : 9% (0.09)
Future Value: 300
Initial Deposit:?
2) Since the current balance is given, let's call it Future Value because the amount that made that $300 is what we need to find out. Let's go find the Future Value since it's been 10 yrs ago. Plugging into the formula we have:
[tex]\begin{gathered} F=P(1+r/n)^{nt} \\ 300=P(1+\frac{0.09}{1})^{1\cdot10} \\ 300=P(1.09)^{10} \\ 300=2.367363675P \\ P=\frac{300}{2.367363675} \\ P=126.723 \\ P\cong126.72 \end{gathered}[/tex]Notice that, since this investment was compounded yearly, so n=1.
3) So the initial deposit, 10 years ago was approximately $126.72

As per the question statement, Mark bought a pen for $0.49, a box of pencils for $1.29, and a pad of paper for $0.98,
And the coach bought 10 ice cream cones for $0.35 each.
We are required to calculate the following:
(a) The total amount Mark had to pay
(b) The total amount the coach had to pay
Starting with part (a),
If Mark bought a pen for $0.49, a box of pencils for $1.29, and a pad of paper for $0.98, then the total amount he will have to pay will simply be the summation of the individual costs, that is, $[0.49 + 1.29 + 0.98] = $ 2.76.
Now solving part (b),
If the coach bought 10 ice cream cones for $0.35 each, then the total amount he/she will have to pay, will be a simple multiplication of the price of one ice cream, with the number of ice creams bought, that is,
$[0.35 * 10] =$3.5

then
f

has no Real solutions.
Explanation:
The x-axis is composed of all points for which
f
(
x
)
(or, if you prefer,
y
) is equal to
0
If the graph of
f
(
x
)
does not have an x-intercept
then it has no (Real) points for which
f
(
x
)
=
0
Step-by-step explanation:
No x-intercept means that it does not cross the x-axis. Thus two solutions is definitely ruled out.
However, if you DO NOT INCLUDE a point of coincidence (Vertex coincides with the x-axis) in the phrase "does not have an x-intercept". Then there could be a single value solution if you equate the quadratic to 0. Some people say that it still has two in such a case but they are both the same value. I do not like this way of thinking!
On the other hand, if you DO INCLUDE a point of coincidence in the phrase, then the plot does not cross the x-axis nor does any point on the curve coincide with it. In such an interpretation there is NO SOLUTION THAT IS REAL. hopes this helps

Question 3 Below are hvo parallel lines with a third line intersecting them. Find the value of x
In this case, we are given the value of one angle and told to find the value of angle x. To do so, we will try to relate them based on the position they have in the diagram.
Notice that the two parallel lines split the space into two. One space is in between the lines, and the other space is outside the lines. We can see that both angles are located outside of the parallel lines.
Now, see that the third line splits the space into two. One space is on the left of the third line, and the other one is on the right of the third line. From the diagram, we can tell that each angle is on an opposite side of the third line.
This two relations between these angles (being outside the parallel lines and on opposite sides of third line) gives them the name of alternate outer angles. This angles have the property that they have the same measure.
So, we have the following
[tex]x=56[/tex]so the measure of x, in degrees, is 56°.
