On a certain sight seeing tour, the number of women to the number of children was 5 to 2. What was the number of men on the sight seeing tour?

(1) On the tour, the ratio of the number of children to the number of men was 5 to 11.

(2) The number of women on the sight seeing tour was less than 30.

The answer here is "C" - the answer can be found using both statements 1 and 2. But I have no idea how they came to an answer using this information. Can someone help?

Thanks!

A 4 year old just asked "why are our brains so soft?" -- the only answer I can come up with is "because it is." Can anyone provide an explanaton as to why the brain tissue is soft?

FDA decides that there is no need for labels to distinguish between animals that are natural and those that have been cloned.

Are you comfortable with that?

Im not!

But they are not asking for our approval or permission so I suppose there is not much we can do about it?

Not to mention they have been doing it (feeding it to us for testing) for over 5 years!

Scary days here in America huh?

I can see the toy speak and spell problems now...

What does a cloned cow say children? OOOOOMm, OOOmmmm... BRAINS!

Disclaimer on the label... There is no difference between real cows and cloned cows the FDA says so.

I know the equation for work is distance x force = work.

Is there such an equation for growth and/or for movement?
