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.
Answer:
Use F.O.I.L method
First, Outter, Inner, Last
So:
5x*7x= 35x^2
5x*-6= -30x
7x*2= 14x
2*-6= -12
So just add it all up, combine like terms and you have your answer.
35x^2 -16x -12
Answer:
8.75 cups
Step-by-step explanation:
3.5:1 (the ratio of batches to 1 batch)
x:2.5 (the ratio of cups of sugar used to the amount used for only 1 batch)
3.5/1=x/2.5 (proportion)
x= 8.75
Answer:
<5 = 105 degrees
Step-by-step explanation:
From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case
<4 = <5 (alternate angle)
Since <4 = 105 degrees, hence m<5 = 105 degrees
