Hi there!
Since ST is a tangent to the circle, we can use the relationship: tangent squared = external secant segment x entire secant segment.
WORK:
(I will be using x in place of ST)
x^2 = 7(23 + 7)
x^2 = 7(30)
x^2 = 210
x = squareroot(210) or approximately 14.5 inches
Hope this helps!! :)
The answer is : multiply 5
30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.
So this "327,000,000,000" needs to be converted into scientific notation, in which the answer that I will get would be 3.27 10^11, in calculation (as in calculator), you will get 3.27E+11.
Hope this helped!

X=3/5
do you need an explanation?
