Okay. If you made a 67 on a test that was worth 100 points, and you had no other grades in that class, then your grade in that class is 67 points out of 100. ( = 67% )

If you did 10 things in that class, and each was worth 50 points, you did perfectly on 6, made a 70% on 1, and made a 0% on 3, then you will have a (100% * 50 * 6  +  70% * 50  +  0% *50 *3) / (50*10)= 335/500. (=67%)

In both cases, your grade is a 67%.

But when you get a 30/30 on those packets, in the first case, your grade will increase to 97/130 = 74.6%

In the second case, your grade would increase to 365/530 = 68.9%

The more work you have done in that class so far, the smaller the impact those packets have on your grade.

I hope this helps.

He shot the guy to make sure he was dead. I think I've heard that before.

I fixed it. You should get a 74.6% if you had a 67 out of 100 to start with and get a perfect score.

If you can, tell us out of how many points you have a 67%??

We can tell you a more accurate answer.

Is this a trick question or is that "someone" you? The 67% is worth what? 67/100? 335/500? What score was obtained on the 3 30 point packets?

Assuming you had a 67/100 in the class, and you made a perfect score on 3 30 point packets, you have a 74.6%. (67+30 / 100 +30 = 97/130) = 74.6%

If your original 67% was worth more points, (for example, if it was calculated from 335/500) then your grade would be closer to 67%.

Honey, the sooner you "grow up" and learn to deal with ignorant fools, the better off you'll be. I was there, right where you are now, hurt by insensitive, rude, foolish individuals. A wise mentor caught a whiff of my misery and gave me some very good, helpful advice. You, as a person, cannot change people. You cannot change what people do, or say, or think. And for that reason, you should absolutely not let other people's folly affect your happiness. Ignore it, and move on. I can speak from experience that it helps. We are very, very sorry that you were hurt here on web2.0calc. Keep in mind that this is a public place and anybody, including hurtful, ignorant fools, can get on here and say whatever they want. Also keep in mind, this is a free service, so don't expect perfection, the mod staff on here can't stop everything, but they do their best. I express full sympathy for you. And I hope you'll consider some of what I say. I hope this was helpful :)

EDIT: I just read the post link above. Nobody on that particular post was being rude! So .... take waht I said up here for general advice ... kay?

1st click on " 2nd " on the top left corner. Then the trig functions should switch to inverse trig functions. Then you can click on and use the trig functions. Every time you need an inverse, click " 2nd ", then click what you need.

I think you can also hold down shift and it works like clicking " 2nd " but I haven't done that yet myself.

I hope this was helpful!

3(14.95) * 4(16.88) = 112.37 so Christine bought 3 videos and 4 CDs.

I divided 112.37 by 7 and the answe was closer to 16.88 so I concluded more CDs were bought than videos. And I was right.

Not very mathematical, but it got the job done :)

You do it yourself :)

Convert the answer to scientific notation by moving the decimal point until the number is between 1 and 10. For a number like 652,000,000, you would move the decimal point 8 places to the left. That gives you 6.52.

The number of decimal places you moved is the power of 10 that you will write. The direction the decimal moved determines whether the power of 10 is negative or positive.

Since we moved 8 places to the left, we would right 6.52 x 10⁸  = 652,000,000

Sorry to say, but you must convert the output to scientific notation yourself.

I hope this was helpful :)

3 x 10⁶  * 4 x 10⁶ =12 x 10¹² or 1.2 x 10¹³.

or 12 trillion

Do not be afraid to use the calculator on this website. If you don't know how much a million is, or anything for that matter, look it up on the internet, that shouldn't be too dificult since you found us. A valuable skill that you need to learn is too try and help yourself before you ask others for help. If you can't do that, you will not go far in life.

43680 * 0.05 = 2184

turn 5% into a decimal by dividing it by 100%. 5%/100% = 0.05. "of" means multiply, so multiply the two numbers together.
