Answer:
Caleb keeps 65% of his mask collection on the wall.
It is immensely important to go through all the details given in the question. Based on those details the answer to the question can be deduced.
Number of G.I. Joe in Betty's collection = 165
Number of G.I. Joe dolls Betty gave to Joe = 165 * (1/3)
= 55
Then the number of G.I. Joe dolls Betty have now = (165 - 55)
= 110
The
number of G.I. Joe dolls that were left with Betty after giving away
1/3 rd of the dolls was 110. I hope the answer is absolutely clear to
you. In future you can always use this procedure for solving similar
kinds of problems.
The mathematical expression of the given complex number above is -5 + 4i. The conjugate of this complex number is that which has an opposite operation. The given is an addition operation. That is -5 - 4i. Therefore, the answer is the third among the choices.
