We calculate the raised money 
raised money=number of computers x price of a computer.
raised money=12($2150)=$25,800

We calculate the profits:
profit=raised money-money spent
profit=$25,800 - $15,000=$10,800

We calculate the percent profit.

$15,000=100%

therefore:

$15,000------------------100%
$10,800------------------    x

x=($10,800 * 100%) / $15,000=72%

Answer: the percent profit will be 72%.

Is 4-heap Nim with heaps of sizes 22, 19, 14, and 11 balanced or unbalanced? Player I's first move is to remove 6 coins from the
nadya68 [22]

Answer:

Player II should remove 14 coins from the heap of size 22.

Step-by-step explanation:

To properly answer this this question, we need to understand the principle and what it is exactly is being asked.

This question revolves round a game of Nim

What is a game of Nim: This is a strategic mathematical game whereby,  two opposing sides or opponent take turns taking away objects from a load or piles. On each turn, a player remove at least an object and may remove any number of objects provided they all come from the same heap/pile.

Now, referring back to the question, we should first understand that:

                        22₂ = 1 0 1 1 0

                         19₂= 1 0 0 1 1

                         14₂= 0 1 1 1 0

                          11₂= 0 1 0 1 1

and also that the “bit sums” are all even, so this is a balanced game.

However, after Player I removes 6 coins from the heap of size 19, Player II should remove 14 coins from the heap of size 22.

¿Cuántos litros de agua se precisa para llenar una piscina inflable de 1/4 de metro cúbico?
8_murik_8 [283]

Answer:

250 litters

Step-by-step explanation:

To solve this question, we first need to know the conversion from cubic meter to liter.

1 cubic meter is equal to 1000 liters.

So, if we have 1/4 cubic meter, we can use a rule of three to find how many liters we will need:

1 m3 -> 1000 L

1/4 m3 -> x L

x * 1 = (1/4) * 1000

x = 1000 / 4 = 250 L

So we need 250 liters of water.
