The area of the square is:
And the area of the circle is:
![\begin{gathered} Ac=\pi r^2 \\ Ac=\pi\cdot(3\sqrt[]{2})^2 \\ Ac=18\pi \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Ac%3D%5Cpi%20r%5E2%20%5C%5C%20Ac%3D%5Cpi%5Ccdot%283%5Csqrt%5B%5D%7B2%7D%29%5E2%20%5C%5C%20Ac%3D18%5Cpi%20%5Cend%7Bgathered%7D)
The area of one segment is given by:
Answer:
y = 8(.88)^x
y = 4.221855 for the fifth reduction
Step-by-step explanation:
We can use the formula
y =ab^x
where a =the initial value
b= 1 -percent decrease
a = 8 inches
b = 1-12%
= 1-.12
= .88
y = 8 (.88)^x
The fifth reduction is
y = 8 (.88) ^5
y = 4.221855
The answer is A because that is the only one that is correct
Answer:
x=9
Step-by-step explanation:
2x+10=28
2x=18
x=9
Teresa gave away 8 baseball cards and has 4 left. 8 plus 4 means she originally had 12. Right now she has 4 out of her original 12 cards remaining. This gives us 4/12. We can simplify this by dividing our greatest common factors. 4 goes into both parts of our fraction, when we divide each part by 4 we end up with 1/3. Since we are unable to simplify this problem any further, this means our solution and fraction is 4/12 aka 1/3.
