Do you really think it is a worn down Egyptian sculpture? Are those really the bases of worn down pyramids around it? If you did not know the Orbiter took photos of what appears to be a face on the surface of mars, several years ago. 10 to the best explanation

I think I figured out the following Q by checking what anwser would work but I hope someone can explain it to me in steps.

A farmer has 160 feet of fencing to enclose 2 adjacent rectangular pig pens. What dimensions should be used so that the enclosed area will be a maximum?

After drawing the picture and naming the short sides x and the long sides y, I think
4x+3y=160
y=(160-4x)/3

I put y back in the first expression: 4x+3((160-4x)/3)=160

I need to do something with the derivative but what?

Out of the answers I can choose only 20ft by 80/3 ft gives me the total of 160ft.
How do I work this problem??

Lets just say that the earth reaches the point where the artic icecap melts and the sea level rises 20 feet (and it will within 50 years if we don't control our greenhouse gas emissions--see movie An Inconvenient Truth). What happens from there? Will the earth turn into a Venus-like planet that will heat up uncontrollably?

(serious answers only, please)

I find this a rather startling fact, but apparently if you accelerate at 1g for half the distance and decelerate at 1g for the other half then you can get to Mars in 1 day. Is this right? How much reaction mass would you need, assuming you could chuck it out the back at a significant proportion of C? How much would you need to go the 4 light years to the nearest star? Is it conceivable that a spacecraft could generate enough power to maintain this kind of acceleration over a long period of time?

A couple of hours ago, my arm started itching. When I noticed the spot it had something that looked like a blister put it had pus in it. It had a red circle around it not really big. But it keeps itching and now the red spot is the size of a dime and it is swollen (the red spot.) The pus pocket or blister is in the center of the red swollen circle. This bite is on my lower left arm & my arm is hurting all the way to my elbow & it is sharp/shooting pains. I am going to search for spider bites but I wanted to try here first since I have found a lot of good answers here. Thanks to those who help me.

I've passed out twice in my life and each time I started dreaming. Of course, I didn't realize I'd passed out until I came to but it was much more disorienting because I'd been dreaming and didn't know what was going on at first. I talked to a friend about it and he said that he started dreaming when he passed out once at the doctor's. So why is that?

Astronomers tell us that Star X or Galaxy Y is 10 billion light years away. How do they know? They have never been there. They don't have a ruler telling them that the star is that far away. What are they using to help them to tell us about these vast distances?
And how can they measure the Milky Way Galaxy? They tell us it is 100 million light years across. What is the standard they are measuring it with?
Sorry, I never took physics or astronomy, so put it in layman's terms if possible.

Is the glue recipe in "Romy and Michele's High School Reunion" factually based? Here's the quote from the movie:
"Ordinarily when you make glue first you need to thermoset your resin and then after it cools you have to mix in a Poxide which is really just a fancy schmancy name for any simple oxygenated adhesive, right? And then I thought maybe, just maybe, you could raise the viscosity by adding a complex glucose derivative during the emulsification process and it turns out I was right."
