The mat doesn't matter. The diameter of the frame would be 12 ft even if there were no mat inside it. The length (circumference) of the frame, just like any circle , is ( pi diameter) = (3.14 x 12) = 37.7 ft.

In 2004, there were approximately 275 students in the Delaware high school band. In 2010, that number increased to 305. Find the annual rate of change in the number of students in the band.

Annual rate of change in the number of students in the band is 5 students per year.

Step-by-step explanation:

In 2004, there were approximately 275 students in the Delaware high school band.

Number of students in band on 2004 = 275

In 2010, that number increased to 305

Number of students in band on 2010 = 305

Duration of years = 2010 - 2004 = 6 years

Increase in number of students in band = 305 - 275 = 30

\\\\\texttt{Annual rate of change in the number of students in the band = }\frac{30}{6}\\\\\texttt{Annual rate of change in the number of students in the band = }5

Annual rate of change in the number of students in the band is 5 students per year.

On a certain survey it says:
12 out 15 people in the United States prefer eating at the restaurant rather than home.
To know how many percent is this.
=> 12 / 15
=> 0.8 which is also 80%
Now, the  80% of the those people in the survey is 400.
Find the total number  of people who took the survey.
Since we already have the 80%, we need to find the number of 20%
=> 400 x 20%
=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey

How do you solve 5v-4 over 10 equals 4/5

First you multiply each side by 10. Your new equation is: 5v-4 = 40/5. This simplifies to 5v-4=8.

Next, you add four to each side, getting 5v = 8+4 or 5v = 12.

Finally, you divide each side by 5. The answer is: v = 12/5

Can you show how to solve this question? Thomas and Sharlina work on weekends and holidays doing odd jobs around the neighborhood. They are paid by the day, not by the hour. They each earn the same whole number of dollars per day. Last month Thomas earned $184 and Sharlina earned $207 a. How many days did each person work? b. Whatis their daily pay PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER

To find out how much they earned, we need to find the GCF of 184 and 207.

The greatest common factor (GCF) of 184 and 207 is 23.

That means they earn 23 dollars per day. That is your answer for part b.

And Thomas worked 184/23 = 8 days
While Sharlina worked 207/23 = 9 days

That is your answer for part a.

1/7 = 0.142857142857142857142857142857142857142857142857142857 and so on

the pattern repeats

the first digit is 1
second digit is 4
third digit is 2
fourth digit is 8
fifth digit is 5
sixth digit is 7

and then the seventh digit is 1, and it repeats

so the six digits repeat again and again...

2012/6 = 335 2/6

It has a remainder of 2, which means that the 12th digit will be 4. because that is the second digit. After going 335 times the 6 digit patterns it will stop at the second digit which is 4.

Your answer is 4.
