If three out of every 200 people contract viral disease how many people will contract the viral disease among 30,000 people solve using proportions.

Step-by-step explanation:

let no of people that contracts it be p.

3/200 = p/30000

200p = 90000

p = 450

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
