Circumference of Circle=C, =2(pi)(radius)
Radius of Circle=r
Side of square=x
f(x)=area of circle
g(r)=area of square
16 feet=C+4x
C=16-4x
2(pi)(r)=16-4x
2(pi)(r)=2(8-2x)
(pi)(r)=8-2x
r=(8-2x)/(pi)
x=(8-(pi)r)/2
f(x)=(pi)(r^2)
f(x)=(pi)((8-2x)/(pi))^2
f(x)=((8-2x)^2)/(pi)
f(x)=((64-32x+4x^2))/(pi)
g(r)=((8-(pi)r)/2)^2
g(r)=((64-16(pi)r+(pi)^2(r^2))/4
Step-by-step explanation:
The probability of u getting an odd number is 1/2
The probability that the second card is less than 5 is also 1/2

1+1=2
for example if you have 1 apple and then you pick another apple you get 2 apples
Answer: The answer is B)
Step-by-step explanation:
The slope of the blue line is
3
4
, and the y-intercept is −1; therefore, the equation for the line is y =

x − 1.
The slope of the black line is −

3
, and the y-intercept is 9; therefore the equation for the line is −

I would use algebra to solve this:
let the amount of child ticket sold be x and the amount of adults ticket sold be 2x
so 2x•9.60+ x•6.30 = 969.00
19.2x+6.30x = 969.00
25.5 x =969.00
x=38
hence ans is 38
an alternative solution would be:
9.60×2 + 6.30 = 25.5
969.00÷25.5= 38
the methods are actually almost the same.
