That is false. A semicircle is 1/2 a circle
It is either in the ones place or the hundred millions place
Answer:
A. XY
Step-by-step explanation:
A chord has both ends on the circle. Point X is not on the circle so segment XY is not a chord.
Ok, to solve this first you have to set up your proportion:
9/150=x/230
/ is a fraction
x= the number of vials it will take to treat 230 patients
in order to solve this, you have to cross multiply:
9 x 230= 2070
150 · x= 150x
so you get 150x=2070
then divide 2070 by 150
2070/150= 13.8
so it would take 13.8 vials of medicine to treat 230 patients
