Answer:
a. a(b)c
b. a(a(b)c)c
d. a(a(a(a)c)c)c
Step-by-step explanation:
We are given the following in the question:

a. a(b)c
It is given b belongs to W.

b. a(a(b)c)c

c. a(abc)c
a(abc)c does not belong to W because we cannot find x in W such that a(abc)c belongs to W.
d. a(a(a(a)c)c)c

e. a(aacc)c
a(aacc)c does not belong to W because we cannot find x in W such that a(aacc)c belongs to W.
Answer:
The correct answer is - 72,349.2
Step-by-step explanation:
Given:
selling price = 7234.92
Initial profit = 16%
we know:
selling price = cost price + profit
Solution:
78300 = cp + 16*cp/100
profit = 78300*16/100 = 12528
cost price = 78300 - 12528 = 65772
then the profit on 10%
= 65772*10/100
= 6577.2
the new selling price = 65772+6577.2
= 72,349.2
186cm
You add all the sides up, so 42+42+51+51 which equals 186cm
