Ever since I've been going out with my boyfriend, I've been seeing a butterfly everyday at the same time...1:37pm. Even if I'm at work, I'l be taking out trash or sweeping and a monarch will breeze right by me. If I'm at school I'll unintentionally go to the bathroom and I'll look out the window and there will be a butterfly flying by. It's a lil weird. If me and my boyfriend have a fight, I won't see one. I wanna know what it means lol. Help me haha

Mary and Joe would like to save up $10,000 by the end of three years from now to buy new furniture for their home. They currently have $2500 in a savings account set aside for the furniture. They would like to make equal year end deposits to this savings account to pay for the furniture when they purchase it three years from now. Assuming that this account pays 8% interest, how much should the year end payments be?

A 12.4 g bullet is fired horizontally into a 98 g wooden block initially at rest on a horizontal surface. After impact, the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.650, what was the speed of the bullet immediately before impact?
The answer I have is 94.01, which is incorrect, though it's within 10% of the correct answer.
Any help would be appreciated!

In the sucker of a cylinder there is 28 g Nitrogen in the temperature: t1= 0’ C. The sucker with section S= 100 cm2, through a drum system is connected to an object with weight 500 N. The cylinder is heated and it reaches the temperature: t2= 100’ C. Find the height in which the object goes down. The pressure of the atmosphere is 1 atm. (The weight of the sucker and the friction is not to be considered.)

My parents didn't go to college and my grandparents and on were all farmers. So I basically came from an uneducated background, and in school my friends all tell me how slow I am when it comes to common sense. Also when there are tests I have to study extra to get the materials through my head, while my other friend barely studies and get the same grades as me. Is it true that genetics affects you intelligence? Like I can become smart through books and become book smart but, when it comes to street smart its all genetics.

It is well known that bullets fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman's chest with bullets of mass m = 2.9 g at a rate of R = 115 bullets/min. The speed of each bullet is v = 560 m/s. Suppose the bullets rebound with no change in speed. What is the average force exerted by the stream of bullets on Superman's chest?

I'm in Algebra 1 and I'm working on intergers and stuff. How would I solve this equation? 3x+9=5
I think it's something like: 3x+9-9=5-9 or something like that. Aren't you supposed to subtract 9 from both sides or something?? Anyway, when I did it like that, the answer was wrong. Help!
