<span>You can use the fact that the work done is equivalent to finding the center of mass of the water in the tank(which is at the center of the cylindrical cross section, which is 3 ft below the level to which the liquid is pumped. Call this distance h.
You then need the total mass of the liquid, volume X density=m. This is where pi comes in!

Kayla has a bowl of beads that contains 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a

Ede4ka [16]

Add all bead colors up

42+28+12+18=100

add up yellow and green

42+28=70

now find out how many beads are not yellow or green by subtracting that from 100

100-70=30

so the first answer is 30/100 -> 3/10 -> 30%

now add up red and green beads

28+18=46

so your next answer is

46/100 -> 23/50 -> 46%

An electronics store sells about 40 MP3 players per month for $90 each. For each $5 decrease in price, the store expects to sell

erma4kov [3.2K]

Step-by-step explanation:

Let's establish our equation first:

for every $5 decrease, there's an additional of 4 MP3 players sold.
to get the monthly revenue, we need to multiple the cost of each player to the number of units sold

$\frac{40mp3}{month} \times \frac{90dollars}{mp3} = 3600 \frac{dollars}{month}$

The equation above is for the basis month.

But the next month, we decreased the cost of mp3 player to sold 4 more units.

$\frac{(40 + 4)mp3}{month} \times \frac{(90 - 5)dollars}{mp3} = 3740 \frac{dollars}{month}$

And the next month, we decreased the cost again to gain 4 more additional units sold.

$\frac{(40 + 4x)mp3}{month} \times \frac{(90 - 5x)dollars}{mp3} = revenue per \: month$

If we substitute x with 2, we get 3840.

If we substitute x with 3, we get 3900.

If we substitute x with 4, we get 3920.

If we substitute x with 5, we get 3900.

At fifth time we decreased our price, we also got lesser revenue.

Therefore, our highest revenue would be $3,900.00 per month at our 4th price decrease with a price of $70.00.
