Answer:
Total Bill = 4006 dollars
Step-by-step explanation:
A cell phone company charges a flat fee of 20 dollars plus 3 cents a call.
If there was a total of 200 calls for the month, the total charge by the cell phone company will be.
Let me convert all to cent first
100 cent = 1 dollar
20 dollar =20 *100
29 dollar = 2000 cent
Charge by the company for a call is 2003 cent
Let me put down the equation.
1 call = 2003 cent
200 calls =( 200 calls* 2003cent)/1 call
200 calls = 200 * 2003cent
200 calls = 400600 cent
Let's convert back to dollar
100 cent = 1 dollar
400600 cent = 400600/100
400600 cent = 4006 dollars

Answer:
60 squaer feet
So lets seperate the shapes one for the bottom small chunk and one for hte big long large top chunk.
To find area you do height times width. So the bottom would be 3 times 4 which is 12 square feet.
Now the top part would be 4+4+4 which is 12 then times that by 4 and get 48.
Now you add 48 and 12 and you get 60 square feet!
Answer:
2nd option
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
the centre is at the midpoint of the endpoints of the diameter.
The coordinates of the centre is the average of the coordinates of the endpoints.
centre = ( 
, 
) = (
, 
) = (- 1, 3 )
the radius is the distance from the centre to either of the endpoints
using the distance formula to calculate r
r = 
with (x₁, y₁ ) = (- 1, 3 ) and (x₂, y₂ ) = (2, - 1 )
r = 
= 
= 
= 
= 
= 5
then equation of circle is
(x - (- 1) )² + (y - 3)² = 5² , that is
(x + 1)² + (y - 3)² = 25
