can anyone anwser this...it is KILLING ME Mth?

7(2)+343(4)+2401(4)=10990

there are 7 girls and each girl has 2 legs, which makes 14 human legs

there 7 big cats with 4 legs each making 28 legs

there are 7 kittens for each of the 7 cats totalling 49 kittens and each kitten has 4 legs making 196 legs

so we have 14 human legs

and in each backpack there are 224 legs.

there are a 7 backpacks per girl making a total 49 backpacks

224*49=10976+14= 10990

There are a total of 10990 legs total

There are 7 girls, giving you 14 legs.

Now you need to find the number of cats and multiply by 4.

We know that there are 7(7)=49 backpacks.

Each backpack has 7 big cats, i.e., there are 49(7) = 343 big cats, giving you 343(4) = 1372 big cat legs

For every big cat there are 7 little cats, that is, there are 343(7)=2401 little cats, giving you 2401(4)=9604 little cat legs.

Add the girl legs, big cat legs and little cat legs to get:

14+1372+9604=10,990 legs

7 girls X 2 legs + 7 backpacs X 0 leg +

7 girls X 7 bacpacs X 7 big cats X 4 legs +

7 girls X 7 backpacs X 7 big cats X 7 little cats X 4 legs=

14+0+1372+9604= 10990 legs

Let g = number of girls

b = number of backpacks

c = number of big cats

k = number of little cats.

It follows that the number of legs = 2g + 4c + 4k

and g =7, b = 7g, c = 7b, k = 7c.

Therefore c = 7^2g = 7^3 and k = 7^3g = 7^4.

And so the number of legs on the bus = 2*7 + 4*7^3 + 4*7^4 = 10990.

Unless its a trick question.

number of big cats = 7*7*7 = 343

number of little cats = 7*7*7*7 = 2401

number of legs = 7*2 + 343*4 +2401*4 = 10,990

7x7 backpacks =49backpacks

49X7cats= 343bigc

343X7little= 2401litttle c

each cat has four legs (hopefully)

2401X4=9604

343X4=1372

the girls each have two legs

7X2= 14

add them up

10,990 legs!

70

Are we counting the legs of the bus driver? If we count his or her legs, it's 10992.
