Answer:
672 ways
Step-by-step explanation:
The total number of ways the friends were supposed to sit without restrictions would have been = 6!
= 720 possible ways.
If the girs should sit on the first or last sit
The possible arrangement= 2!4!
= 2*24
= 48
But now the two girls should be arranged in such a way that the don't sit on either the first or the last chair.
So the possible way now is= way without restriction - way if the girls are to sit at either first or last sit
= 720-48
= 672
Answer:
Step-by-step explanation:
in complementary angle sum of two angle is always 90 degree.so,
let another be x
x+28.1=90
x=90-28.1
x=61.9
therefore another angle is 61.9 degree.
Answer:
-6 and -6

1. Exponential
2000 times 2= 4000 (60)
4000 times 2= 8000 (120)
8000 times 2= 16000 (180)
16000 times 2= 32000 (240)
2. pull a 2x out of everything
answer is b
Answer:
D get $ 63, G get $9, J get $18.
Step-by-step explanation:
Given : D has 90 dollars. He gives 0.1 of them to G. He gives 0.2 of them to J. He keeps the rest.
To find : How much does each person get?

D has 90 dollars.
He gives 0.1 of them to G.
i.e. 
So, he gives $9 to G
He gives 0.2 of them to J.
i.e. 
So, he gives $18 to J
Total he give 9+18=$27
D will left with 
Therefore, D get $ 63, G get $9, J get $18.
