Answer:
The answer is zero there is no solving.
Step-by-step explanation:
cause you do
60/n=20/7, and then you move all the terms to the left
now it is: 60/2-(20/7)=0
the domain to this is n=0
add the numbers and variables together and get
60/n-(+20/7)=0 now get rid of the parentheses and now you got
60/n-20/7=0
and all that is 0

Answer:
Angle of Elevation
If a person is looking up at an object, the angle of elevation is the angle between the horizontal line of sight and the object. Angle of elevation problems can be solved by using trigonometry as the problem can be modeled as a right triangle.
The MIB agent is on the ground looking up at the alien at the top of the CN tower, and we need to find the angle he should shoot his laser gun. Therefore, we need to find the angle of elevation.
Diagram attached, where [tex]x[/tex] is the angle of elevation.
To find the angle of elevation, use the tan trig ratio:
[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven:
O = 553.3 mA = 67 mSubstituting the given values into the formula and solving for x:
[tex]\implies \tan(x)=\sf \dfrac{553.3}{67}[/tex]
[tex]\implies x= \tan^{-1} \left(\sf \dfrac{553.3}{67}\right)[/tex]
[tex]\implies x=83.09557654...^{\circ}[/tex]
Therefore, the angle of elevation is 83° (to the nearest degree).
Here is a hexagon.
Work out the value of x.
150°
140°
56°
Answer:
x = 142
Step-by-step explanation:
The sum of the internal angles in a hexagon is 720°
2x° + 150° +56° + 140° +90° = 720
2x° + 436° = 720°
2x° = 720 - 436
x° = [tex]\frac{284}{2} =142[/tex]

Mark transferred songs from his computer onto his portable music player. He transferred songs in minutes. How many songs did he transfer per minute?
Answer:
Need more info
Step-by-step explanation:
You're working with rates. It's relatively straight forward. Take miles per hour for instance. If you travel 60 miles in one hour, you're rate of speed is 60 miles per hour.
You haven't given any data in this example but the idea is the same. Let's say he transferred 10 songs in 5 minutes. That's means his rate is 10 songs per 5 minutes. You can change that to a fraction so it's easier to understand:
[tex]\frac{10 songs}{5minutes}[/tex]
Now just reduce the fraction and it becomes
[tex]\frac{2 songs}{1 minute}[/tex]

On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.
Chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a Catcher card.
Chad should not have included the values (1, 2) and (3, 6) because the ratio would be different for these points.
Chad should have changed the axes for the Infield and Pitchers cards so it was the same order as the table.
Chad needs to switch the order of each (x, y) value to show the decreasing values of the Pitchers cards.
The true statement for Chad graph is that:

EGG DROP The physics class is holding an egg drop competition. The formula h= −16t2+h0 can be used to approximate the number of seconds, t, it will take for the eggs to reach height, h, from an initial height of h0 in feet.
Find the time it takes an egg to reach the ground if it is dropped from an initial height of 40 feet. Round to the nearest hundredth, if necessary.
By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.
How long will take the egg to reach the ground?
Here we know that the initial height of the egg is 40ft, so the equation for the height will be:
[tex]h(t) = -16*t^2 + 40[/tex]
The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:
[tex]h(t) = -16*t^2 + 40 = 0\\\\16t^2 = 40\\\\t^2 = 40/16\\\\t = \sqrt{40/16} = 1.58[/tex]

Two corresponding sides of two similar triangles are 3 cm and 5 cm. The area of the first triangle is 12 cm. What is the area of the second triangle?
Since the are of the first triangle is 12 cm², the area of the second triangle is 33.33 cm².
To answer the question, we need to know what similar triangles are
What are similar triangles?Similar triangles are triangles in which the ratio of their corresponding sides is constant.
Given that the corresponding sides of the two similar triangles are 3 cm and 5 cm respectively. Also, the area of the first triangle is 12 cm². We need to find the area of the second triangle.
Area of second triangleSince the triangles are similar, we have that
(side of second triangle/side of first triangle)² = Area of second triangle/Area of first triangle
Area of second triangle = (side of second triangle/side of first triangle)² × Area of first triangle
= (5 cm/3 cm)² × 12 cm²
= 25/9 × 12 cm²
= 25/3 × 4 cm²
= 100 cm²/3
= 33.33 cm²

Female 120 93 63 34
Adult 173 103 72 58
Baby 52 61 33 28
The relative frequencies for the given table are:
Male → 13/44Female → 17/86Adult → 29/86Baby → 7/43How to get the relative frequencies?
The relative frequency of a given element out of a set, is given by the quotient between the number of that element and the total number of the set.
Here we can see that the total number of moose is:
52 + 34 + 58 + 28 = 172
There are 52 male moose, then the relative frequency for male moose is:
M = 52/172 = 26/86 = 13/44
There are 34 female moose, then the relative frequency is:
F = 34/172 = 17/86
There are 58 adult moose, so the relative frequency is:
A = 58/172 = 29/86
There are 28 baby moose, so the relative frequency is:

Which data set could be represented by the box plot shown below?
Answer:
B
Step-by-step explanation:
A box and whisker plot is a graphical representation of the 5-number summary of a data set. It shows the minimum, maximum, median, and the values of the 1st and 3rd quartiles. Here, you're asked to identify the data set having the same 5-number summary as that shown in the plot.
__
extremesThe minimum of the data set is shown by the end of the left "whisker." The plot shows a minimum value of 41. Choice C has a minimum of 40, so is not the data set we're looking for.
The maximum of the data set is shown by the end of the right whisker. The plot shows a maximum of 50, matching all of the answer choices shown.
medianThe median of the data set is shown by the vertical line in the middle of the box. Here, the median of the data set is indicated as 44. This will be the middle value, or the average of the two middle values of the set of data.
These sets of data have 10 values, an even number, so the median is the average of the middle two.
Choices A and B have a middle pair of 43 and 45, which means their median is (43+45)/2 = 44. Choice D has a middle pair of 43 and 47, so a median of (43+47)/2 = 45. Choice D is not the data set we're looking for.
quartilesThe 1st and 3rd quartiles of the data set are shown by the left and right ends of the box, respectively. They are indicated as being 43 and 48.
The median divides the data set into two parts. It is not considered to be a member of either part. The 1st quartile is the median of the lower (left) part. The 3rd quartile is the median of the upper (right) part.
Here, each part has 5 data values, so the quartile values are 3rd from the ends of the data set. In choice A, they are 43 and 49, not a match to the given plot. In choice B, they are 43 and 48, matching the values in the given box plot.
The data set in choice B could be represented by the box plot shown.

From the below graph option B is correct.
What is graph function?The graph of a function f is the set of all points in the plane of the form (x, f(x)).
It is also define as the graph of f to be the graph of the equation y = f(x).
Given,
Three different function for h(x)
[tex]\frac{1}{4}x -4 , x \leq 0\\ \\\frac{1}{3} x -3, 0 < x \leq 3\\\\\frac{1}{2} , x\geq 4[/tex]
From the above function,
x ≤ 0, the slope of the graph of h(x) is [tex]\frac{1}{4}[/tex]
0 < x ≤ 3, the slope of the graph of h(x) is [tex]\frac{1}{3}[/tex]
x ≥ 4, the slope of the graph of h(x) is [tex]\frac{1}{2}[/tex]
As we progress from left to right,
The slope of h(x) increases and the slope of the graph becomes steeper.
Therefore,
