Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
797,100 deaths x
---------------------------------- = -------------------------
350,000,000 people 100,000 people
or:
797,100 deaths x
--------------------------- = -----------------
3500 people 1 people
Result: 228 deaths per 100,000 people
Plural because it has eaten
Well, equation of circle is (X-X1)^2 + (Y-Y1)^2 = R^2
so, (X-4)^2 + (Y-3)^2 = 25
X^2 + 16 -8X + Y^2 + 9 - 6Y = 25
X^2 + Y^2 - 8X - 6Y = 0
this is the correct answer hope it helped :)
