there are 500 coins in a jar, the owrht is 30$, the coins are nickles and dimes. how many of each kind is there?
just need some help this prob
if the value (or total amount) of these two kinds of coins is thirty dollars..
let n = # of nickles, so 500-n = # of dimes.
 
0.05n + 0.10(500-n) = 30.00 expressed the total value; solve for n and you'll then be able to give each count requested.
start with 50 easys. if you solve those quickly, then move into mediums. hards are pretty tricky tbh i just attempt then peek answers/memorize lol * **in** australia, the most common quantity per pack is 25, but some brands have changed them to 26 or to 20 (the minimum by law). 30, 40 and even 50 packs are also sold. christmas jigsaw - christmas jigsaw is a game for children from 2 to 8 that features 40 different puzzles to solve. it has 4 options for the number of pieces: 5x5,6x6,7x7 and 8x8. the game has auto-save when is interrupted. it could be a random drop or a glitch. if you've got the item and nothing else is wrong with the game, enjoy! if the amount is very low. it is normal. dont worry hi,

lots of great explanations below, but i fear they might be difficult to truly conceptualize. 

let's start with a pie!

if there's a pie in front of us, that is the market. we'll call it 100 units of pie

we cut the pie in half - one piece (50 pie units) for you, and one piece (50 pie units) for me

scenario 1: we do nothing, we both have 50% market share.

scenario 2: i eat half my pie. my pie slice is now 25 units, yours is still 50 units. as a result, you have 67% of the market share and i have 33%. my "revenues" have fallen and my market share has fallen. your revenues haven't changed but you've gained market share

scenario 3: not only do i eat half my pie, but you also eat 20% of yours. still, i ate more, so even though your "revenues" are down, you've still gained market share.

scenario 4: we both get given more pie (yay). but, i get a whole other 50 units, and you only get 5 more. your "revenues" are up, but you've still lost market share!

i've created the below image for you to visualize this better (click on it to blow it up)...hope this helps! 500 there are 2 pints in a quart. there are 4 quarts in a gallon. 1 quart = 2 pints answer: `1.00` no, there arent that many.. lets see.. the oscars, the vma's, the ama's, the cma's, the daytime emmys, the primetime emmys, the tonys, the screen actors guild awards, the golden globes, the peoples choice awards, the blockbuster movie awards, the alma awards, the espy's, the bafta's.. oh my, i see your point...
