Station A and Station B are 120 miles apart. A train traveling from station A to station B travels exactly 1/3 of the distance when it is held up and stops for 16 minutes. When the train continues its journey,the engineer increases its avarage speed by 15 mph so that the train will arive at station B on schedule. Find the avarage speed of the train before it stopped for minutes
The required average speed of the train is calculated to be 60 mph, when the train travels certain distance and stops.
Distance between station A and station B is given as 120 miles.
A train traveling from station A to station B travels exactly 1/3rd of the distance when it is held up and stops for 16 minutes.
Let, its average speed was x mph.
Then, total time taken if it didn't stop = 120/x h
Now, before stop it took time = ( 1/3 × 120)/x h = (40/x) h
After stop the time it took = 80/(x + 15) h
i.e, 40/x + 16/60 + 80/(x+15) = 120/x
⇒ 80/(x + 15) + 8/30 = 80/x
⇒ 80(1/x - 1/(x + 15)) = 8/30
⇒ 10 × (15/x² + 15x) = 1/30
⇒ x² + 15x = 10 × 15 × 30
⇒ x² +15x - 450 = 0
⇒ x² +75x -60x - 450 = 0
⇒ (x+75)(x-60) = 0
⇒ x = 60 or, x = -75
As speed cannot be negative, the average speed is 60 mph.

Answer:
1 = 18
Step-by-step explanation:
Mrs. Everett, the P.E. teacher, is pairing off students to race against each other. Antonio can run 8 meters per second, and Devin can run 9 meters per second. Mrs. Everett decides to give Antonio a head start of 50 meters since he runs more slowly. Once the students start running, Devin will quickly catch up to Antonio. How long will that take?
Write a system of equations, graph them, and type the solution.
The time it took for Devin to catch Antonio is given as follows:
50 seconds.
How to model the situation?The position functions for each of Antonio and Devin can be modeled by linear functions in slope-intercept format, as follows:
y = mx + b.
In which:
The slope m represents the velocity.The intercept b represents the initial position.Antonio starts 50 meters in front of Devin, hence the functions, considering their velocities, are given as follows:
A(x) = 50 + 8x.D(x) = 9x.(these two equations compose the system of equations).
Devin will catch up to Antonio when:
D(x) = A(x).
Hence:
9x = 50 + 8x
x = 50 seconds.

If Georgia and Farrah work together, it takes them 8 minutes to clean the espresso machine at their coffee shop. Alone, Farrah takes 12 minutes less than Georgia to clean the machine. If x is the number of minutes it takes Georgia to clean the machine by herself, the situation can be represented by this equation
Georgia takes 24 minutes to clean the espresso machine by herself.
The correct answer is an option D.
The equation for the situation is:
[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8}[/tex]
here, x is the number of minutes it takes Georgia to clean the machine by herself.
We need to find the value of x.
Consider the equation,
[tex]\frac{1}{x} +\frac{1}{x-12} =\frac{1}{8} \\\\\frac{(x -12)+x}{x(x-12)}=\frac{1}{8}\\\\\frac{x -12+x}{x^2-12x}=\frac{1}{8}[/tex]
(2x - 12) × 8 = x² - 12x
16x - 96 = x² - 12x
x² - 12x -16x + 96 = 0
x² - 28x + 96 = 0
x²-24x-4x+96 = 0
(x - 24)(x - 4) = 0
x = 24 or x = 4
If x = 4, then x - 12 would be negative which is not possible.

In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
A straight line is shown and is marked with three angles. The first angle measures 60 degrees. The second angle measures 60 degrees. The third angle is labeled y. The line between the 70 degree angle and angle y extends below the straight line. The angle formed is labeled angle x.
Write and solve an equation to determine the measure of angle x. (5 points)
Your answer:
The equation x + (60 + 70)° = 180° is used to solve for the measure of the vertical angle x = 50°
What are vertically opposite anglesVertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.
The angle y and x form vertical angles, so x = y
Angle y form a straight line with 60° and 70° so we have the equation to solve for x as:
x + 60° + 70° = 180° {sum of angles on a straight line}
x + 130° = 180°
x = 180° - 130° {subtract 139° from both sides}
x = 50°
Therefore, the measure of the vertical angle x is equal to 50° derived with the equation x + (60° + 70°) = 180°.

Solve the equation ax + b = c for x.

Answer:
X = C - B
--------
A
Step-by-step explanation:
Solving for X is pretty much getting X alone on one side of the equal sign. That's when we would do the "opposite" of what the original equation is showing. And we do that to both sides.
For example, we see +b. The opposite of addition is subtraction, so we do just that. We do -b on BOTH sides of the equal sign. b -b = 0. It cancels it out. c-b is just as it says. So now we have ax = c-b.
Now we see ax are right next to each other with no symbol, which means they are being multiplied. The opposite of multiplication is division. So we'll do that exactly. We will divide A on both sides. ax/a gets rid of that a and leaves the x alone. Dividing c-b/a gives you just that, making the answer X = C-B/A

Define the term scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of such a different size is known as a scale factor (bigger or smaller).It is important to specify how significantly the shape has grown when describing expansion. For instance, a scale factor of 3 shows that the new geometry is three times as large as the original.The shape will just be smaller if the scaling factor is a fraction. Reduction is the term for this. So, a scaling factor of 1/2 shows that the new geometry is equal to half of the old shape.For the stated question:
The scale factor of a enlargement is 8 because a microscope displays a picture of an object which is 8 times larger than the object actually is. A 7 millimetre bug has a body length.Then,
body length (under microscope) = 7*8 millimeters

The total number of ounces needed to serve all guests (6 oz/guest * 80 guests) and then divide that number by the size of the bottle (25.4 oz) to get the total number of bottles needed.
In order to calculate the number of champagne bottles needed to serve all 80 guests, we need to use the formula for calculating the total number of ounces needed. The formula is: Number of bottles * size of bottle + total ounces of glasses * number of guests. In this case, the number of bottles needed is: (6 oz/guest * 80 guests)/25.4 oz bottle = 18.9 bottles. Therefore, 19 champagne bottles will be needed to serve all 80 guests. This is because each bottle holds 25.4 ounces and each guest needs 6 ounces of champagne, so we need to calculate the total number of ounces needed to serve all guests (6 oz/guest * 80 guests) and then divide that number by the size of the bottle (25.4 oz) to get the total number of bottles needed.

How do I find the perpendicular line of y = -3x + 2. The perpendicular line passes through the point 6, 8 (please break down into steps)
Answer:
y = [tex]\frac{1}{3}[/tex]x + 6
Step-by-step explanation:
The equation we currently have right now is y = -3x+2. Since we know that the line equation is y = mx + b, let's take out m to find the slope of a perpendicular line. M will be -3.
To convert a regular slope to a perpendicular one, we have to:
- reciprocal/flip it (this means that if m = 3, the perpendicular will be [tex]\frac{1}{3}[/tex])
- swap the signs (this will mean that if a number is positive, then it will become negative)
Therefore, if m = -3, the perpendicular slope will be [tex]\frac{1}{3}[/tex] (we flipped and changed signs)
Now, we are also given that this line passes through the point (6,8), so we can use this formula: [tex]y - y1 = m(x-x1)[/tex]
What do we know right now?
- y1 = 8 (from (6,8))
- x1 = 6 (from (6,8))
- m = [tex]\frac{1}{3}[/tex]
Let's plug in what we know:
y - 8 = [tex]\frac{1}{3}[/tex](x - 6)
y = [tex]\frac{1}{3}[/tex](x-6) + 8
y = [tex]\frac{1}{3}[/tex]x - 2 + 8
y = [tex]\frac{1}{3}[/tex]x + 6

What are the explicit equation and domain for an arithmetic sequence with a first term of 9 and a second term of 1?
The explicit equation for this arithmetic sequence is: aₙ = 9 + (n-1)(-8).
What in mathematics is an arithmetic sequence?An arithmetic series is one that has the following formula: a, a + d, a + 2d, a + 3d, a + 4d,... The basic distinction of the sequence is d, and the number an is the first term. An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d.
How do you discover the mathematical order?The formula for an arithmetic sequence is given as an=a1+(n1)d, where an a n is a broad term, a1 a 1 is the initial term, and d is the huge distinction. This is done in order to locate the general phrase in the list.
The general form of the explicit equation for an arithmetic sequence is:
an = a1 + (n-1)d
Given that the first term is 9 and the second term is 1,
d = a2 - a1 = 1 - 9 = -8
So the explicit equation for this arithmetic sequence is:
aₙ = 9 + (n-1)(-8)

In a quadrilateral ABCD,if m(<A)=80,m(<B)=100° and m(<D)=110°,find m(<C).
In quadrilateral ABCD, m∠C = 70°.
What is quadrilateral?A quadrilateral in geometry is a four-sided polygon with four edges and four corners.
Given:
ABCD is a quadrilateral.
m∠A =80°, m∠B = 100° and m∠D = 110°.
The sum of all the interior angles is 360°.
m∠A + m∠B + m∠C + m∠D = 360°.
80 + 100 + 110 + m∠C = 360
m∠C = 360 - 290
m∠C = 70°
Therefore, m∠C = 70°

Step-by-step explanation:
In a quadrilateral, the sum of the measures of the angles is 360 degrees. Therefore, if we know the measures of three of the angles in a quadrilateral, we can use this information to find the measure of the fourth angle.
In this case, we know that:
m(<A) = 80 degrees
m(<B) = 100 degrees
m(<D) = 110 degrees
So, to find m(<C), we can use the equation:
m(<A) + m(<B) + m(<C) + m(<D) = 360
Substituting in the known values, we get:
80 + 100 + m(<C) + 110 = 360
Solving for m(<C), we get:
m(<C) = 360 - (80 + 100 + 110) = 360 - 290 = 70 degrees
So the measure of angle C is 70 degrees.
A cylinder has a height of 6 in. and a radius of 8 in.
How does the cylinder's lateral area compare to the sum of the areas of the two bases?
Use π≈3.14.
Enter your answer rounded to the nearest tenth in the box to correctly complete the statement.
The lateral area of the cylinder is approximately
square inches less than the sum of the areas of the two bases.
Answer:
see below
Step-by-step explanation:
h = 6
r = 8 ==> area = πr² = 3.14*8² = 3.14 *64 =201.0
top & bottom = 2*200.96 = 401.9
r=8 ==> perimeter = 2πr = 2*3.14 *8 = 16* 3.14 =50.2
lateral area = h*perimeter = 6*50.24 = 301.44
so it's about 100 sq inch less
