Change a speed of 50 metres per second to a speed in kilometres per hour.
Answer:
180m/s
STEP BY STEP EXPLANATION:
1m/s = 3600/1000 km/h
50m/s = 3600/1000 * 50
= 36 * 5
= 180m/s
A student in eighth grade notices that the current cost of tuition, books, and fees at a 4 year college is $14,000 per year. The family reads that there is an annual increase of $550 per year. What will the the total cost of tuition, books, and fees for this student when this student attends college for four years, after graduating high school? $63,700 $68,100 $70,300 $72,500.
Answer:
$68,100
Step-by-step explanation:
$14,000 : 9th grade
$14,000 + $550 = $14,550: 10th grade
$14,550 + $550 = $15,100: 11th grade
$15,100 + $550 = $15,650: 12th grade
$15,650 + $550 = $16,200: year 1 of college
16,200 + $550 = $16,750: year 2 of college
$16,750 + $550 = $17,300: year 3 of college
$17,300 + $550 = $17,850: year 4 of college
16,200 + 16,750 + 17,300 + 17,850 = $68,100
Answer:
$68,100
$14,000 + $550 = $14,550: 10th grade
$14,550 + $550 = $15,100: 11th grade
$15,100 + $550 = $15,650: 12th grade
$15,650 + $550 = $16,200: year 1 of college
16,200 + $550 = $16,750: year 2 of college
$16,750 + $550 = $17,300: year 3 of college
$17,300 + $550 = $17,850: year 4 of college

For which value of x does f(x) = 2
Answer:
x = -4Step-by-step explanation:
Look a the picture.
Draw the horizontal line y = 2.
Common point: (-4, 2).
Conclusion: f(x) = 2 → x = -4
From the graph at x = -4, then value of f(x) will be 2.
What is Graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
In the given graph, first we have to draw a line f(x)=2 i.e y=2
Draw the horizontal line y = 2.
We have to check where the horizontal line is meeting the line in graph.
Then we get a Common point at (-4, 2).
So x value is =-4 for f(x)=2 in the given graph.

Step-by-step explanation:
a furniture company currently produces 5800 chairs per month. If production decreases 5%, find the amount of the decrease and the new number of chairs produced each month.
Answer:amount of decrease 290 ;numbers of chairs 5510
Step-by-step explanation:
Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Number of chairs produce in a month = 5800
5% decrease in production:
= 5% of 5800
= 5/100 x 5800
= 5 x 58
= 290
The number of new chairs produced each month:
= 5800 - 290
= 5510
Thus,
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.

{(1, 5),(2, 6),(3, 6),(4, 1),(4, 20),(5, 21),(6, 24)}
We have x = 4 repeating itself
If we graph the two points (4,1) and (4,20), then we see the relation fails the vertical line test.
The input x = 4 leads to more than one output y = 1 and y = 20 simultaneously.
This is why we don't have a function.
The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -
(4, 1), (4, 20).
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the coordinates as -
{(1, 5), (2, 6), (3, 6), (4, 1), (4, 20), (5, 21), (6, 24)}
The given set does not represent the function as one value of [x] has two values of [y] in the coordinates -

Answer:

At the us open tennis championship a statistician keeps track of every serve that a player hits during teh torunment. The statistcian reported that the mean serve speed of a particluar player was 101 miles per hour and teh standard deviation of the serve speeds was 11 mph. If nothing is known about the shape of distribution give an interval that will contain the speeds of at least eight ninths of the players serves
Answer:
68mph to 134 mph
Step-by-step explanation:
We apply
Chebyshev's Theorem States:
At least 3/4 or 75% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
From the question,
Mean = 101 miles per hour
Standard deviation = 11 miles per hour
We are to give an interval that will contain the speeds of at least eight ninths of the players serves
Hence, we apply the rule
At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
μ - 3σ
= 101 - 3(11)
= 101 - 33
= 68 miles per hour
μ + 3σ.
= 101 + 3(11)
= 101 + 33
= 134 miles per hour
Therefore, the interval is 68mph to 134 mph

Which of the following two-dimensional shapes can be rotated to create a cone? Right triangle Square Circle Ellipse.
Refer to the figure below for an example.
Imagine the right triangle acts like a propeller to spin around to carve out the 3D shape of a cone. The axis of rotation is the vertical part of the triangle. In a sense, it's like a revolving door of sorts.
In contrast, a square and rectangle will rotate around to create a cylinder. An ellipse or circle rotates around to form a (squashed) sphere.

Hey there!
Here; Looking at it we can state that it is a Right angled triangle.
And must use the Pythagoras relation if the triangle is a Right angled triangle.
So, let's work on it.
Let ABC be a triangle.
Taking reference angle as C, we get;
perpendicular= 3m
Hypotenuse= 7m
Base = xm
Now;
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]or \: b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]
Put all values.
[tex]b = \sqrt{ {7}^{2} - {3}^{2} } [/tex]
Simplify to get answer.
[tex]b = \sqrt{49 - 9} [/tex]
[tex]b = \sqrt{40} [/tex]
Therefore, X= 6.3m.

Points A and B are two of the vertices of a right triangle. They are the endpoints of the hypotenuse AB¯¯¯¯¯ of the triangle. The third vertex of the triangle lies in the first quadrant.
Plot a point at the location of the third vertex.
Answer: (1, 2)
Step-by-step explanation:
There are many possibilities for the third point in the first quadrant
The simplest case is drawing a line parallel to x axis from point A and drawing a line parallel to y axis from point B and see where they intersect
The two lines would be:
y=2, x=1
So the point of intersection is (1,2) and they intersect at right angle hence qualify as a third point
Therefore, one possible location for third point is (1,2)
Answer:
Point (1 , 2)
Step-by-step explanation:
AB will form the hypotenuse and this will be the vertex.
In order to solve the following system of equations by subtraction, which of
the following could you do before subtracting the equations so that one
variable will be eliminated when you subtract them?
4x – 2y=7
3.x – 3y = 15
A. Multiply the top equation by 15 and the bottom equation by 7.
B. Multiply the top equation by 1/3.
O C. Multiply the top equation by 3 and the bottom equation by 4.
D. Multiply the top equation by-3 and the bottom equation by 2.
4x – 2y=7
3x – 3y = 15
we want to keep y by eliminating the x
so we will Multiply the top equation by 3 and the bottom equation by 4.
we will get
12x - 6y = 21
12x - 12y = 60
we subtract the equations
12x - 6y - 12x - (-12y) = 21 - 60
6y = -39 and so on
The cost, in dollars, of making x cups of lemonade is x+25. The predicted revenue is 12+2x dollars. Write a polynomial that represents the profit of selling x cups of lemonade. If you sold 20 cups of lemonade, will you make a profit? (yes or no)
Answer:
P = x - 13
Yes, you will make a profit
Step-by-step explanation:
Given;
cost of making x cups, C = x + 25
predicted revenue, R = 12 + 2x
Profit of selling x cups is given by;
P = R - C
P = (12 + 2x) - (x + 25)
P = 12 + 2x - x - 25
P = x - 13
When 20 cups of lemonade are sold, the profit made can be estimated using the profit function above;
P = x - 13
P = 20 - 13
P = 7
Thus, you will make a profit
