Average rainfall for the 9-day= 19/80 inches

Step-by-step explanation:

3/10 + 1/5 +1/10+ 3/10+ 2/5 +"1/5+1/5+1/5=19/10

Average rainfall= 19/10 ÷ 8= 19/10 ×1/8=19/80 inches

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

if i put something wrong your not gonna like it so rather not say nothing.
