Calculate the indicated length in the figure.
[Pre-Calculus honors] Find the rotation in revolutions per minute given the angular speed and the radius given the linear speed and the rate of rotation.
37. V= 82.3 m/s, 131 rev/min
38. V= 144.2 ft/min, 10.9 rev/min
39. V= 553 in. /h, 0.09 rev/min
Please do all of them, or at least as many as you can.
Answer: To find the rotation in revolutions per minute (RPM) given the angular speed and the radius, we can use the formula:
RPM = (Angular Speed (rad/s)) / (2 * pi)
To find the RPM, we first need to convert the linear speed to angular speed. We can do this by using the formula:
Angular Speed (rad/s) = Linear Speed (m/s) / Radius (m)
Angular Speed = 82.3 m/s / 0.131 m = 630 rad/s
RPM = (630 rad/s) / (2 * pi) = 131 rev/min
To find the RPM, we first need to convert the linear speed to angular speed. We can do this by using the formula:
Angular Speed (rad/s) = Linear Speed (ft/min) / (Radius (ft) * 12)
Angular Speed = 144.2 ft/min / (10.9 ft * 12) = 10.9 rad/s
RPM = (10.9 rad/s) / (2 * pi) = 10.9 rev/min
To find the RPM, we first need to convert the linear speed to angular speed. We can do this by using the formula:
Angular Speed (rad/s) = Linear Speed (in/h) / (Radius (in) * 3600)
Angular Speed = 553 in/h / (553 in * 3600) = 0.09 rad/s
RPM = (0.09 rad/s) / (2 * pi) = 0.09 rev/min

Question: PartA Can you draw a Gaussian surface that offers a simple way to compute the electric field surrounding a charged dipole? O Yes O No
It is impossible to create a Gaussian surface that makes it easy to calculate the electric field around a charged dipole. Thus, the response is no.
According to Gauss's law, the enclosed electric charge directly affects how much an electric field's net flux is moving over a closed surface. This is given by, [tex]\phi=\frac{Q}{\epsilon_0}[/tex], where the electric flux is represented by Ф, the permittivity of free space is represented by [tex]\epsilon_0[/tex], and the enclosed charge is represented by Q.
Gauss's law must be applied for the symmetric charge distribution required for the given surface in the equation [tex]\frac{Q}{\epsilon_0}=\int\vec{E}\cdot d\vec{A}[/tex] to have a single value of the electric field.
The electric field surrounding a charged particle can be estimated using the Gaussian surface. Gauss' Law cannot be applied to the dipoles because electric dipoles lack a surface with a symmetric distribution of the electric field all around them.

Step-by-step explanation:
combine the like terms together.
In four years' time, Imran's mother will be three times as old as Imran. Six years ago, his mother was seven times as old as him. Find
(i) Imran's present age,
(ii) the age of Imran's mother when he was born.
Answer:
(i) 11 years old
(ii) 30 years old
Step-by-step explanation:
K is x
In four years, he will be x+4 and his mother will therefore be 3(x+4)
Six years ago, he was x-6 and his mother was 7(x-6).
In 10 years his mother went from 7(x-6) to 3(x+4)
so their difference is 10
7x-42+10=3(x+4), since 7x-42 is 10 years less than 3x+12
7x-32=3x+12
4x=44
x=11 age of K now
in 4 years he will be 15 and his mother 45.
Six years ago he was 5 and his mother 35
Therefore, his mother was 30 when he was born.
She is now 41.
Imran is currently 10 years old. His mother's current age is 34 years old and she was 24 years old when Imran was born.
Explanation:The question involves a system of equations based on the relationship between Imran and his mother's ages. We can define Imran's current age as i and his mother's current age as m. From the problem we have the following two equations:
In four years' time, his mother will be three times as old as him: m + 4 = 3 * (i + 4)Six years ago, his mother was seven times as old as him: m - 6 = 7 * (i - 6)
By solving this system of equations, we can determine that Imran's current age (i) is 10 years old and his mother's current age (m) is 34 years old. To find the age of Imran's mother when he was born, we would subtract Imran's age from his mother's, i.e., 34 - 10, so Imran's mother was 24 years old when Imran was born.

a train traveled at an average speed of 45 miles per hour for 40 minutes, and at an average speed of 60 miles per hour for 1 hour. what was the average speed of the train, in miles per hour, for the trip?
So, the average speed of the train is 54.09 miles per hour.
To calculate the average speed of the train for the entire trip, you need to find the total distance traveled and the total time traveled.
First, you can convert the time traveled at each speed to hours. 40 minutes is equal to 40/60=0.67 hours. So the total time traveled is 1+0.67=1.67 hours.
To find the total distance traveled, you can use the formula: distance = speed x time. At 45 mph, the distance traveled is 45 x 0.67 = 30.15 miles. At 60 mph, the distance traveled is 60 x 1 = 60 miles. Therefore, the total distance traveled is 30.15 + 60 = 90.15 miles.
Finally, you can use the formula: average speed = total distance / total time.
Average speed = 90.15 miles / 1.67 hours = 54.09 miles per hour.

O 9 ft, 7 ft, 2 ft
so we have hmmm 4 sets above, hmm let's check say the second set, the triangle with sides 5, 9, 3. Check the picture below.
we have three sides, let's look at the two smaller sides first, 5 and 3.
if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side? Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 5 - 3 = 2. However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle. So whatever the third side may be, it must be greater than 2.
Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 3 + 5 = 8. However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle. So whatever the third side may be, it must be less than 8.
so for those reasons the third side can't be 9, it won't work for a triangle, even 8 is not good, so it must be less.
Now, if we look at the 1st set and 4th set, we end up with the same dilemma, the longest side is too long.
If we take a looksie at the 3rd set however with small sides of 6 and 7, it gives us a third side that must be more than 1 but less than 13, so 7 fits just nicely, so that one works.

the four longest rivers in the world are all named after types of monkeys the howler river is 230 Mi longer than the Barbary River the Gin river is 150 Mi longer than the Barbarian River the retinal river is 30 miles shorter than the Barbary River the rivers when combined have a total length of 19,230 Mi how long is each River?
Answer: We can set up a system of equations to represent the information given:
Let x = length of Barbary River
Howler River = x + 230
Gin River = x + 150
Retinal River = x - 30
Total length = x + (x + 230) + (x + 150) + (x - 30) = 19,230
We can then use substitution and the equations above to solve for the length of each river:
x + (x + 230) + (x + 150) + (x - 30) = 19,230
4x + 350 = 19,230
4x = 18,880
x = 4720 (length of Barbary River)
Howler River = x + 230 = 4720 + 230 = 4950 mi
Gin River = x + 150 = 4720 + 150 = 4870 mi
Retinal River = x - 30 = 4720 - 30 = 4690 mi
Step-by-step explanation:
alma starts running and jacob starts running 7 seconds later. let t represent the number of seconds since alma started running. write an expression (in terms of t ) that represents the number of seconds jacob has been running.
The expression that represents the number of seconds Jacob has been running is t - 7.
A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations. This mathematical operation enables the multiplication, division, addition, or subtraction of numbers. An expression's structure is as follows: (Math Operator, Number/Variable, Math Operator). The two integers are connected by a mathematical operator.
Since Jacob started running 7 seconds after Alma, the number of seconds Jacob has been running can be represented as t - 7. So the expression that represents the number of seconds Jacob has been running is: t - 7.
