Answer:
4/pi
Step-by-step explanation:
The area of the square is
A = s^2
The area of the circle is
A = pi r^2
The diameter of the circle is s, we need to find the radius
d = 2r
s =2r
Divide by 2
s/2 = r
A = pi *(s/2) ^2
A = pi (s^2/4)
We want the ratio of the A square/ A circle
s^2/ pi (s^2/4)
The s^2 cancels
1/ pi (1/4)
4/pi
perfect square?
A. 2-12
B. 3-8
C. 4-6
Answer:
C. 4-6
Step-by-step explanation:
4 is the perfect square because when you do 2 x 2 you get 4. None of the other numbers are a perfect square.
The expression for total number of points gained = 2x+17
Points earned for completing x levels = 4x+12.......(1)
Points lost in the video game = - (2x-5) [negative as they are lost]......(2)
Total Points gained = Algebraic sum of equation 1 and equation 2 =
(4x+12) + {- (2x-5) }
Hence the expression for net points earned now = 4x+12 -2x +5 = 2x+17
