(a) The perimeter of the shape is the sum of half a circumference and the diameter itself.
The circumference of a circle with radius is , and since we can write the circumference as
So, half a circumference is
Ad we get the perimeter by addind the diameter:
(b) Given the perimeter, we can solve for :
So, we can divide both sides by the parenthesis and we have
Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side
6x - 7x = 2 + 3
-x = 5
x = -5
I hope this helps.
Yes they will all be trapezoid
The total cost of the ticket is the sum of the base ticket price, p(x) = 15x + 10, and the service charge, c(x) = 5x + 2. Therefore, from the word sum, the operation involved is Addition. This is the first among the choices given.
