In total group 1 makes xm cakes per hour

In total group 2 makes yn cakes per hour

so altogether they make (xm+yn) cakes per hour,

On average this is  (xm+yn)/(x+y) cakes per student per hour.

I think that is what the question is asking for but the working is not very clear....

Thanks Alan :)

Ben throws four identical darts. Each hits one of four identical dartboards on the wall. After throwing the four darts, he lists the number of darts that hit each board, from greatest to least. How many different lists are possible?

It depends on what is imortant in the count. I mean is each board classed seperately of is is just the number of darts one any board that matters.

I'll assume it is just the number of darts that matter

Here are the possible answers

0004

0013

0022

0211

1111

That is 5 posiblilities :)

Never mind

Guest, please DO NOT delete your answer unless you really believe it is totally incorrect.

If that is the case then leave a note saying so. Thanks.

I have no idea what you are on about Splatmaster.

(x^3+250x^2+100x) / (1\2x^2+25x+9)

The meaning of the question is not clear.

What is the backwards slash for?

If it is a divide sign is the 1 divided by everything after it or is it only divided by the 2 or perhaps by only the 2x^2   ??

Hi,

I have tried to show you with this sketch.

I have found the new point for just one of the vertices, you should be able to work our where the other two points go.

If you have any questions you can ask :)

Hi Helper,

There is no super quick answer to this but here are some video units you can watch to learn a little about matrices.

The Khan academy has some really great teaching tools, you maye find these quite interesting. :)

Thanks guest
