A circle has a circumference of 16π yards. Find the area in terms of π (pi).

Answers

64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.

64 pi is the answer if I’m correct

A) 20/77

B) 30/121

The answer would be A)20/77.
The reason is that without replacement it would go (10/22)*(12/21)=0.2597
You can do the easy route I did then do (20/77) which would also give you 0.2597.
The answer is exactly A there is not other choises make sense

A music store is having a clearance sale. All items are discounted by 20%. What is the sale price of a radio that regularly costs $30?

Answers

Answer:

24

Step-by-step explanation:

You would first multiply 20% by $30. Then you would get 6 and subtract 6 from $30.

Answer:

$24

Step-by-step explanation:

Method 1: find 10% of 30 = 3 (just divide 30 by 10)

then double it to make 20% = 6

subtract 6 from 30 to give 24.

Method 2: 20% = 1/5

To find 1/5 of a number, divide it by 5.

30 divided by 5 = 6.

Then subtract 6 from 30 = 24.

Method 3: to decrease a number by 20% multiply it by 0.8.

30 x 0.8 = 24

What is 6(5j + 4 + 3j) after using distributive property. Please explain your answer.

Answers

Answer:

Step-by-step explanation:

30j + 24+ 18j

48j + 24

Answer:

48j+24

Step-by-step explanation:

6(5j + 4 + 3j)

when there is a number outside of the parenthesis you have to multiply everything in the parenthesis by that number

6x5j=30j

6x4=24

6x3j=18j

so now we are left with 30j+24+18j

the final step would be to combine like terms

the only like terms are 30j and 18j

30j+18j=48j

so the final answer is

48j+24

Read Digital Field Trips to the Grand Canyon.The Grand Canyon is one of Arizona's most well-known tourist attractions. People from all over the world visit this natural wonder every year. It is also a popular field trip for students living close enough to make the journey. For some, though, visiting the Grand Canyon is not easy and is certainly not possible for a field trip. Students living hundreds of miles away may never have the opportunity to visit this world-class destination. That is, until recently. Due to a new program created by the National Park Service, students from all over the world are now able to experience the Grand Canyon. They visit the park through digital field trips.In the past, programs at the park focused on those for physical visitors to the park. To improve access, the park has unveiled a permanent Virtual Studio for Kids to help the "visit" the park. Improvements in green-screen technology have allowed the park to make high quality videos. These videos make students feel like they are right there in the park. Though education programs have been limited for years, students are now able to connect with experts in the park. These experts include park rangers, scientists, geologists, and other experts. Students can now directly ask questions. They can now learn about the Grand Canyon by talking to the professionals that know it best.A major reason that students from across America and the world have been unable to visit the Grand Canyon is the high cost of taking a field trip to Arizona. Teachers in states like New York would have to organize accommodation, travel, and food for students, resulting in an expensive field trip that many schools and students simply cannot afford. The National Park Service has thought of this too. It now offers five different, free interactive presentations for different age ranges. Teachers just need to sign up early in order to secure their spot for this digital field trip.

Larry is considering two investment strategies. The first strategy involves putting all of his available funds in Project X. If Project X succeeds, he will receive a $10,000 return, and if it fails, he will suffer a $2,000 loss. There is a 70% chance Project X will succeed and a 30% chance it will fail. The second strategy involves diversification: investing half of his funds in Project X and half of his funds in Project Y (which has the same payoff structure as Project X). If both projects succeed, he will receive a $5,000 return from Project X and a $5,000 return from Project Y, for a net gain of $10,000. If both projects fail, he will suffer a $1,000 loss on Project X and a $1,000 loss on Project Y, for a net loss of $2,000. If one project succeeds and one fails, he will receive a $5,000 return from the successful project and will suffer a $1,000 loss on the failed project, for a net gain of $4,000. As with Project X, there is a 70% chance that Project Y will succeed and a 30% chance that it will fail. Assume that the outcomes of Project X and Project Y are independent. That is, the success or failure of Project X has nothing to do with the success or failure of Project Y.
