A person has $30,000 to invest. As the persons financial consultant, you recommend that the money be invested in Treasury bills that yield 2%, Treasury bonds that yield 4%, and corporate bonds that yield 6%. The person wants to have an annual income of $1120, and the amount invested in corporate bonds must be half that invested in Treasury bills. Find the amount in each investment.

What is the solution? (hint: write 3 equations using x=treasury bills, y=treasury bonds, z=corporate bonds.)

Up to the date of a fire that completely destroyed all of Singer's inventory, Singer had sales of $2,000,000 and purchases of $1,800,000. The cost of beginning inventory was $140,000 and the company's typical gross profit was 40 percent. Using the gross profit method, estimate Singer's inventory loss from the fire. (Show your work.)

So... this may sound crazy, but....

Me and my boyfriend started dating a little over a year ago. I always had flawless skin, I'm not bragging..but I literally never had pimples. ever. Once we started dating, i noticed that i was getting acne. It wasn't bad at first, but after a couple months it got really bad. I tried everything to get rid of it- nothing was working!!! i went to the doctor and got medicine (didn't work) nothing worked! we dated for almost a year, and then we decided to take a break for a little bit because we were having some problems. We broke up for about four months..within the first month of our break i noticed my acne was gone! COMPLETELY gone. i didn't have one pimple the whole time we were broken up. We decided to get back together one night.. and within the first week of us being together i have acne again. I'm not taking a few zits here and there... i'm taking full on acne. 30-40 zits at a time.. a pizza face as some people call it. it's horrible! we've been back together for about three months now and my acne is just getting worse! my whole face is covered.

it's just weird because i never had acne before we dated.. and when we broke up it went away. why is this??? i'm not stressed out with him or anything.. i'm way happier with him than i am without him.

so long story short...

my fiance and i had sex on the 23rd. we didn't use any protection whatsoever and he came inside me. four days later, on the 27th i started bleeding.. i thought it was my period but it only lasted one day? i just..don't know. i mean, maybe it was my period. i just don't understand why it lasted one day. what else would the bleeding have been from? could i possibly be pregnant? if so, what was the bleeding from?

i love my fiance, and yes, we would keep the baby, if i was pregnant. and we would LOVE them. i'm not in any way worried..just anxious to know. we weren't plaaning on having kids until we got married. but, we're as ready now as we'll ever be. so don't think i would have an abortion or anything like that.

how soon can you take a pregnancy test? i'm sorry i'm asking so many questions.. i'm just so new to this. i have no insurance, and can't really afford to see a doctor right now..my mom will help us out in any way. i just don't want to ask her until i know for sure that i am pregnant.

I have Winterboard on my iPod touch 2nd gen. and ever since I installed it, my cydia app will not work. Many people have told me that if i remove Winterboard, Cydia will work fine again. Well, problem is: winterboard will not go away! I went into Cydia, clicked manage, clicked Winterboard, clicked remove, and then confirm.. and it came up with an error. every time. Maybe it has nothing to do with Winterboard, but if not, then why is my Cydia comming up with an error every time I try to use it?

i left my calculus book at home, like an idiot.

so, my function is (when being dropped from the same height, the time it takes for an object to hit the ground is a function of the objects weight.) right?

well, what's that formula? like, say i'm dropping a 5 pound brick from a 10 foot building how do i calculate the time it'd take it to hit the ground?

i know there is a formula for it, i just can't remember it!

help ):

what is speed measured in?

like, time is measured in seconds.

weight in pounds and so on.

what about speed?

okay, so i know people will probably call me stupid. but, oh well :)

so, am i understanding this right.. inorder to use the internet on my ipod, i have to have a router to plug it into? if so, how do i get a router? better yet, what is a router?!
