The angular speed of the bicycle's wheels that are traveling at 25 mi/h is 1885.7 rad/min
To solve this angular speed problem the formula and the procedure we will use is:
v = w * r
Where:
v = tangential velocityw = angular velocityr = radiusInformation about the problem:
v = 25 mi/hd = 28 inchw = ?Calculating the radius of the wheel, we have:
r = d/2
r = 28 inch/2
r = 14 inch
Converting the velocity unit from mi/h to inch/min, we get:
25 mi/h * (63360 inch / 1 mi) * (1h / 60 min) = 26400 inch/min
Applying the tangential velocity formula and isolating the angular velocity, we get:
v = w * r
w = v / r
w = 26400 inch/min / 14 inch
w = 1885.7 rad/min
What is angular speed?When an object is in uniform circular motion, the angle described by the radius in each unit of time is known as angular speed. It is measured in units of (rad/s) (revolutions/s).

Write a function called height_range that accepts a list of integers representing heights in inches as an argument and returns the the difference between the tallest height and the shortest height. Assume that all heights are positive values.
The following function height_range in python language will accept a list of integers and return the difference between the tallest and shortest height.
What is a python programming language?Python is a well-liked computer programming language used to build websites and software, automate procedures, and conduct data analysis. Since Python is a general-purpose language, it may be used to create a wide range of applications and isn't specifically designed to address any particular problems. Because of its high-level built-in data structures, dynamic typing, and dynamic binding, it is appropriate for Rapid Application Development as well as for use as a scripting or glue language to connect existing components.
Given that, the Function should accept a list of integers as arguments, and the return type should be an integer value which is the difference between the maximum and minimum element from the list function will be:

Determine whether the ordered pair is a solution of the linear inequality.
x ≤ 3; (–2, 6)
Answer:
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].
Hence, (-2, 6) is a solution to the linear inequality.
Step-by-step explanation:
Given the linear inequality
x ≤ 3
substitute the value of x = -2
-2 ≤ 3
TRUE
It is clear that -2 is indeed less than 3. Thus, the ordered pair (-2, 6) is a solution to the linear inequality.
Also,
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].
Hence, (-2, 6) is a solution to the linear inequality.

The table shows the location of four cities relative to sea level.
Which city is closest to sea level? Explain.
City Location Relative to Sea Level
A –0.25 meter
B 74 meters
C −32 meters
C 0.5 meter
City A; –0.25 is closest to 0 on a number line.
City B; 74 has the greatest absolute value.
City C; −32 is farthest from 0 on a number line.
City D; 0.5 has the least absolute value.
Answer:
The correct answer is City D.
Step-by-step explanation:
When you say the phrase, "closer to sea level" you mean the closest to the very top of the sea, like "0" on a number line.
This means, that whether it is to the left of the right of the number line (or above or below the sea) whichever one has the lowest absolute value is the closest.
Therefore, the correct answer is City D.
Hope this helps! :D

A Liberian sorts 350 books at a constant role. After a days, the librarian still has 150 books to son, How much time does it take to sort the books from start to
finish
Answer: 7 days
Step-by-step explanation:
Books already sorted;
= 350 - 150
= 200
Time taken = 4 days
Rate = 200/4
= 50 books a day
150 books remain;
= 150/50
= 3 days
Total time = 4 + 3
= 7 days

Answer:
D) 121 degrees
Step-by-step explanation:
A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.
In this case, since supplementary angles add up to 180 degrees, we set up an equation:
<A+<B=180
(6x-19)+(11x-22)=180
17x-41=180
17x=221
x=13
Now we plug in x=13 for angle B:
11x-22
11(13)-22
143-22
121
Therefore, the measure of angle B is 121 degrees

Let logp/n=5 and logm/n=9
Answer:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P

What does a midpoint of a line segment create? a) a point that is equidistant to all points on the segment b) two line segments of equal length c) a point equidistant from the two endpoints
The option b and c is correct.
To solve this problem we must be aware of the concepts of line segment. And also what is a mid point.
When we connect two dots or two points it forms a line segment or we can say that line segment is part of line which is bounded by two points.
Mid-point of any line or line segment is that point which divides the line segment into two equal parts and also a point which is equidistant from the two endpoints.
So, a midpoint of a line segment divides the line segment in two equal parts and is also equidistant from the two endpoints.
Here, the appropriate option is b and c.

According to the given statement Andrea have to mark 440 yards out of 1760 for her race course.
The yard is defined as:A yard (yd) is a length unit used in various different systems, including US customary measures, Imperial units, and historic English units. It is 3 feet, 36 inches, or 0.9144 meters.
What exactly seems to be the conversion factor?A conversion factor seems to be a number that can be used to multiply and otherwise divide one set of units by another set of units. The right conversion factor must be used when converting to something like an equivalent value. For example, to convert inches to feet, the appropriate conversion value equals 12 inches equals 1 foot.
According to the given information:Want quarter-mile course for a race.
Total yards she has is a = 1760
We know that:
1 mile = 1760 yards
quarter-mile (.25) which means = 1760/4
