Answer:
11²= 121
5³= 125
2⁷= 128
Step-by-step explanation:
The whole numbers can be multiplied with themselves to get numbers between 120 and 130 .
For example
11*11= 121
This can be written in the exponent form as
11²= 121 which is between 120 and 130.
Also
5*5*5= 125 or
5³= 125 which is also between 120 and 130.
and
2*2*2*2*2*2*2= 128
2⁷= 128 which is between 120 and 130 as required.
We see that as the powers or exponent increases the whole number is decreased.
b. 24
c. 120
d. 360
e. 720
Answer:
D = 360
Step-by-step explanation:
Number of monsters that arrive at the theater = 6
Total number of arrangement for the 6 mobsters = 6!
= 6*5*4*3*2*1
= 720
The chance that Frankie will be behind Joey is half while the chance that Joey will be behind Frankie is half.
Since Frankie wants to stand behind joey in the line though not necessarily behind him, the arrangement can be done in 6!/2 ways
= (6!) 1/2
= 720/2
= 360 ways
