the radius of the wheel on a bike is 19 inches. if the wheel is revolving at 140 revolutions per minute, what is the linear speed of the bike, in miles per hour?
Answers
Therefore, the linear speed of the wheel on a bike is approximately 0.9π miles per hour.
What is meant by linear speed?The pace at which an object travels a specific distance in a predetermined amount of time is known as linear speed. By dividing the distance traveled by the time it takes to cover that distance, it may be used to determine how rapidly an item is travelling in a straight line. For instance, if a car moves 100 meters in 10 seconds, its linear speed is 10 meters per second. Linear speed is distinct from average speed, which takes into account any variations in velocity or direction throughout the duration of a voyage. Linear speed is also distinct from tangential speed, which is the pace at which an item travels along a circular route. Physics' fundamental idea of linear speed.
How to solve?
C=2πr,
C=2π(19)=38π.
linear speed of v=(38π/60)*5280=33.6π feet per second.
final speed of v=(33.6π/3600)*60=0.9π miles per hour.
Therefore, the linear speed of the bike is approximately 0.9π miles per hour.

Answers
Thus, the scale factor by which he increased his screen size is 3:2
What is scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.
Given, the pixel of Mike's old calculator = 96 pixel
His new calculator has pixels = 144 pixel
Scale by which it increased = New pixels/Old pixel

What are arithmetic operations?The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.
The given problem can be written in terms of expression as,
42 ÷ 51860
It can be solved as follows,
The number of digits in 51860 is 5 and in 42 is 2.
In order to divide the two numbers, the dividend should be greater than the divisor.
Therefore, multiply both 42 and 51860 by 10000 to obtain,
(42 × 10000) ÷ (51860 × 10000)
⇒ 420000 ÷ (51860 × 10000)
Now, first divide 420000 by 51860 to get,
420000 ÷ 51860 = 8.0987

What does profit means ?
Profit is the term used to describe the financial gain experienced when the revenue from a commercial activity exceeds the costs, costs, and taxes associated with maintaining that activity.
Any profits generated are returned to the company's owners, who can decide whether to keep the money for themselves, pay dividends to shareholders, or reinvest it in the company.
Entire revenue less total costs equals profit.
Companies report gross profit, operational profit, and net profit for accounting purposes (the "bottom line").
Investors are drawn to profitable businesses because these businesses either distribute their earnings as dividends to shareholders or invest them back into the business, which raises stock value.
According to the question Company lost 20% from its profit and it reached to 66 million that means
let X be the total profit of the year
X - loss percent = 66 millions
X - X (20/100) = 66 million
X-0.2X = 66 million
0.8X = 66 million
X= 66/0.8 million
X = 82.5 million
So, 82.5 million was the profit the year before

The vertices of ▲ XYZ are X (6,-5), Y (3,0), Z (-4, 9). A XYZ is translated 3 units left and 8 units up. Then, it is translated 2 units right and 6 units down. What is the final translation rule that maps the pre-image to the final image?
Answers
Answer:
After the first translation, the coordinates of the vertices of the triangle will be X (3,-13), Y (0,-8), Z (-7, 1). After the second translation, the coordinates of the vertices will be X (5,-7), Y (2,-2), Z (-5, 7).
The final translation rule that maps the pre-image to the final image is a translation of 2 units right and 6 units up. This can be written as a translation rule of the form (x, y) -> (x + 2, y + 6).

After the first translation the coordinates are:
(x, y) → (x - 3, y + 8)After the second translation the coordinates are:

Mary has 96 fliers to post around town. last week she posted 1/6 of them. this week she posted 1/4 of the remaining fliers. How many fliers has she still not posted?
Answers
Answer:
Start with 60 fliers
post 1/4 of fliers so 60*.25=15
60-15=45 left
post 1/5 of remaining so 45*.20=9
45-9=36 left
Step-by-step explanation:
Last week: (had 60) (used 1/4)= (60)(1/4)= 15. So, you used 15.
You have 60-15=45 left. This is how many you have to start the week.
This week: (had 45) (used 1/5)= (45)(1/5)= 45/5=9. So, you used 9.
This means that you have 45-9= 36 left.
Mary Still did not post 60 fliers.
Total fliers Mary was having = 96
Fliers she posted last week = 1/6 = 0.16
Fliers left with Mary after posting 1/6 part last week
= 96 x 0.16
= 16
Fliers left with Mary after the posting of 1/6 of them
= 96 - 16
= 80
Now the new remaining number of fliers with Mary = 80
Fliers she posted this week = 1/4 = 0.25
Fliers left with Mary after posting 1/4 part this week
= 80 x 0.25
= 20
Fliers left with Mary after the posting of 1/4 of them this week
= 80 - 20
= 60
Therefore, the fliers that Mary still did not post = 60

it is a regular pentagon.
so, all side lengths are equal, and also all cross connections between corners are equal.
that makes TR parallel to PQ.
and that makes SPQ an isoceles triangle (both legs are equally long). and the smaller triangle S to x to the angle to the right of x is similar to SPQ, which means they have the same angles.
so, the triangle interior angle at P = the triangle interior angle Q = y.
and they must be the same as the bottom 2 interior angles of the small triangle.
x and the angle right to x are equal too, as they are the triangle exterior (supplementary) angles to the bottom 2 interior angles of the small triangle.
we know that the sum of all angles of the internal trapezoid (PQ to x and its right neighbor) is 360.

What is Coordinate Geometry?The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.
A straight line is represented using its slope and a point on the line using point slope form. This indicates that the point slope form is used to get the equation of a line whose slope is "m" and which passes through the points (x 1, y 1). The equation of a straight line can be expressed in several ways. Point slope shape is one of them. Y - Y 1 = m(x - X 1) is the equation for the point slope form, where (x1, y1) is a randomly chosen point on the line and m is the slope of the line.
The slope of the line is 1.5
The Point through which the equation will satisfy is (6,12)
Therefore the equation of the line in Point-Slope form is
y - y1 = m ( x- x1)
⇒ y - 12 = 1.50 ( x - 6)
Option D, The equation that satisfy the situation is y - 12 = 1.50(x-6).

If each unit on the grid represent 25 feet, then the perimeter of the factory is 1000 feet
Each unit on the grid represent 25 feet
The length of the side w1 = 3 × 25

The length of the side N1 = 13 × 25
= 325 feet
The length of the side E1 = 7 × 25

The length of the side S1 = 5 × 25

The length of the side W1 = 4 × 25

The length of the side S2 = 8 × 25

The perimeter of the factory = 75 + 325 + 175 + 125 + 100 + 200

The required zeros of the function y=(x-3)(x + 2)(x-2) is given as 3, -2, and 2. Option C is correct.
Here,
Zero of the function are the values of x, for a function for which the function gives y = 0,
So let y = 0, - - - - - -(1)
Put y = (x-3)(x + 2)(x-2) in equation 1
(x-3)(x + 2)(x-2) = 0
Equating each parenthesis step by step with zero,
x - 3 = 0 ; x + 2 = 0 ; x - 2 = 0
x = 3 ; x = -2 ; x = 2
So the values that came out are 3, -2, and 2, are said to be zeros of the given function,
