We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.
To find the area of community pool we will use area of pentagon formula.
, where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.
Let us find the perimeter of our given pentagon by multiplying each side length by 5.

Now let us find apothem of our pentagon by using Pythagoras theorem.





Upon substituting our given values in above formula we will get,



Therefore, the area of the pool that needs to be covered is 960.42 square feet.
Question is unclear to me ,, can you rewrite it in a nicer way so i can answer?
Simple just do normal simple algebra:)
Answer:
0.75 cents
Step-by-step explanation:
You take...
$2.25 and subtract $1.50 to get 0.75 cents
In-depth...
Start off with taking a dollar away...
2.25 - 1.00 = 1.25
Then take off 0.50 cents...
We know that 0.50 cents are two 0.25 cents
So, we take off one 0.25 cent
1.25 - 25 = 1.00
Then the next 0.25 cents
*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)
<--- it is just adding 25 each time
If we subtract 0.25 cents from a dollar we get...
0.75 cents
Answer:
21/41
Step-by-step explanation:
Find the total number of students
6+7+2+3+6+8+4+5=41
Then find the students that do not study chemistry
6+7+2+5 = 20
P( not study chemistry) = do not study chem)/total
=21/41
