Answer:
120960
Step-by-step explanation:
We get 11 books 7 of geography and 4 of chemistry
We need to line all of them with 2 constraints
1.-three of the geography must be: 1 in the middle and in each end, then we already have
C₄,₃ = 4! / ( 4 - 3 ) ! C₄,₃ = 4*3*2*1
C₄,₃ = 24 different ways
Now we have 7 books of chemistry. To place them we get
P₇ = 7! P₇ = 7*6*5*4*3*2*1 P₇ = 5040
Now the total number will be
C₄,₃* P₇ = 120960
First you need the same denometer Which is 12
9/12+2/12 = 11/12
So 1/12 pie is left

Answer:
No he wont.
Step-by-step explanation:
50% of 40=20
40+20=60
40+8=48
Michael has 48 and Susan has 60
9•10^4 / 3•10^3 = 30.
The whale has 30 times the mass of the elephant, or 29 times more. For that reason, it's 29 times heavier than the elephant.
