consider the length of the minute hand the radius of a circle
the diameter would be 16*2 = 32 inches
circumference ( distance around the circle) =
PI *32
using 3.14 for PI
3.14 *32 = 100.48 inches Round the answer as needed
The best estimate of r is 0.

0.05= 5*10^(-2)
As a matter of fact, the coefficient should be ≥ 1 and < 10.
0.05 written in scientific notation is 5*10^(-2)~
Hope this helps~
The solution to the system of equations x + 2y = 1 and -3x-2y = 5 is:
x = -3, y = 2
The given system of equations:
x + 2y = 1............(1)
-3x - 2y = 5..........(2)
This can be written in matrix form as shown:
![\left[\begin{array}{ccc}1&2\\-3&-2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}1\\5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%5C%5C-3%26-2%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%5C%5C5%5Cend%7Barray%7D%5Cright%5D)
