Answer:
60
Step-by-step explanation:
1/6(x+6)=11
1/6x+1=11
1/6x=11-1
1/6x=10
1/6/1/6=10/1/6
10x6=60

Answer:
31
Step-by-step explanation:
CPCTC and Parallel concurrency theorem
1/2 because 6/7 and 6/5 are over 1 and 3/4 is greater than 1/2
V (Volume) = s^2 * h = 48 ------> h = 48s^-2
C (Cost) = (4sh)(2) + (2s^2)(1) = 2s^2 + 8sh = 2s^2 + 8s(48s^-2) = 2s^2 + 384s^-1
dC/ds = 4s - 384s^-2 = 0 ------> 4s(1 - 96s^-3) = 0
Since s can't be 0, the only possible solution is:
1 - 96s^-3 = 0
s^3 - 96 = 0
s = cube root(96) = 2 cube root(12) ~ 4.579 cm
s^2 = 4 + 2 cube root(18) = 2[2 + cube root(18)]
h = 48/s^2 = 24/[2 + cube root(18)] ~ 5.194 cm
