Answer:
Step-by-step explanation:
After selecting A there are 6 letters that are not K out of the remaining 7 letters so 
P(!K)=6/7
 
        
             
        
        
        
height,h = 3"
base, b = length, l = 2
area of triangle, t = bxh/2...eqn 1
area of square, s = l^2...eqn 2
area of pyramid, p =4t + s...eqn 3
subst h = 3 and b = 2 in eqn 1
t = 3x2/2 = 3
subst l =2 in eqn 2
s = 2^2 = 4
subst t = 3 & s = 4 in eqn 3
p = 4(3) + 4 = 16sq inch
 
        
             
        
        
        
B. 12 guest per table all you need to do it’s divide 216 and 18
        
             
        
        
        
Answer:
a=41.8 BC=2.8
Step-by-step explanation:
sin30/6=sinx/8
8*sin30=6sinx
4=6sinx
sin^-1(4/6)
angle a
cosine rule
bc^2=3^2 +5^2-2(3)(5)*cos30
BC^2=
BC=2.83
2.8
