If a wheel makes 12 of a rotation in 2 seconds, what is the angular velocity, in radians per second?

Answers

Answer:

angular velocity = 12π Radians per second

Step-by-step explanation:

The angular velocity is a measure of the rotation/revolution speed of an object, relative to another point.

In order to present the answer in radians per second, let us first establish the relationship between radians and rotations/revolution.

one complete revolution = 360° = 2π Radians

∴ 1 roration = 2π Radians

12 rotations = 12 × 2π Radians = 24π Radians

Angular velocity in radians = 24π Radians in 2 seconds

Now let us convert to radians per seconds.

24π Radians = 2 seconds

2 seconds = 24π Radians

∴ 1 second = (24π Radians) ÷ 2

1 second = 12π Radians

∴ angular velocity = 12π Radians per second

Answer:

1/ 6

7/ 12

Step-by-step explanation:

Answer:

7a) 1/7

7b) 7/12

Step-by-step explanation:

For 7a) you know that the denominator of 5/6 is equal to 6 so that means you should make 1 have a denominator of 6. To do that, you have to multiply the denominator and the numerator by 6 to get 6/6-5/6=?. With this, you could easily solve the two fractions because they have equal denominators. You subtract the numerator and keep the denominator. 6-5=1 so the answer is 1/6.

For 7b) I would first convert 1 3/12 into an improper fraction. To do that, you have to multiply the whole number by the denominator then add the numerator. It will look like this 12x1+3/12 which is equal to 15/12. This makes the question easier to solve. You then want to convert 2/3 to have a denominator of 12. To do that, you have to multiply 4 on the numerator and denominator. This will turn the fraction into 8/12. After you do that, you can easily subtract the fractions again. you do 15-8/12 which is equal to 7/12.

How would you find the percent of discount if the sale price is $61.75 and the original price is $95

Answers

Answer:

Sale Price = $61.75 (answer). This means the cost of the item to you is $61.75. You will pay $61.75 for a item with original price of $95 when discounted 35%. In this example, if you buy an item at $95 with 35% discount, you will pay 95 - 33.25 = 61.75 dollars.

You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one shirt.
A) Graph the system of equations.
B) What was the price of the shoes and each shirt?

Please answer and take seriously will give brainliest

Answers

Step-by-step explanation:

1. making the equation:

shoes = x

shirts = y

175 = x + 3y

x = 4y

2. graph it (I'm using desmos)

the green line is for 175 = x + 3y and the purple one is for x = 4y

3. find the price

x = 4y

175 = 4y + 3y

175 = 7y

y = 175/7 = $25

price of the shirt = $25

x = 4y = 4*25 = $100

price of a pair of shoes = $100

He keeps = 150

And, he gives her = 100

As he saves 12% of his share

i.e.

= 12% of 150

= 18

Now the number of weeks is

= 360 ÷ 18

= 20 weeks

Answers

Mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

What is mean?

Mean is the sum of numbers divided by the numbers. It is also known as average.

How to calculate values?

Fow calculating mean we have to find sum of numbers which is calculated in figure as 1553.

Mean=1553/25=62.12

Mode is basically the number having higher frequency which is 53.

Median is[ (n+1/2)th term,(n/2)th term]/2

=(60+60)/2

= 60.

Range is basically the difference of smallest number and largest number divided by 2=82-49=32

Q3=3(N+1)/2

=3(25+1)/2

=18.5th term which is 69.

Hence mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

F(x) = (x-5)/3x(x+ 1)

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?

Answers

Answer:

115.02 feet

Step-by-step explanation:

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?

We solve this question using the Trigonometric function of tan

tan x = Opposite/Adjacent

x = Angle of depression = 72°

Opposite = Height of the tower = 354 feet

Adjacent = Distance of the airplane from the base of the tower = y

Hence,

tan 72 = 354/y

Cross Multiply

tan 72 × y = 354

y = 354/tan 72

y = 115.02157247 feet

Approximately = 115.02 feet

Therefore, the distance of the airplane from the base of the tower is 115.02 feet

if you go over to the right 3 then your adding 3 to the x intercept or subtracting 3 from ^x+1 so it would be ^x-2

the y intercept part is easy all you have to do is subtract 2 from the y intercept so it would be +2

The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas.Which details are used to support the main fact in the fifth paragraph?
