A Red bucket has 200 L of water and has been filled at a rate of 6 liters per minute A blue bucket hats 500 L of water and is be

Masteriza [31]

Answer:

<em>Both buckets will have the same amount of water after 25 minutes</em>

Step-by-step explanation:

<u>Equations</u>

Let's call:

t = number of minutes elapsed for both buckets

The red bucket already has 200 L of water and it's flowing in at a rate of 6 liters per minute. Thus, the volume of water in this bucket is:

R = 200 + 6t

The blue bucket has 500 liters of water and is being drained at 6 liters per minute. The volume can be modeled by the equation:

B = 500 - 6t

The condition for both buckets to have the same amount of water is:

R = B

200 + 6t = 500 - 6t

Adding 6t and subtracting 200:

6t + 6t = 500 - 200

12t = 300

t = 300/12

t = 25 minutes

Both buckets will have the same amount of water after 25 minutes

Suppose a drawer contains six white socks, three brown socks, and seven black socks. We draw one sock from the drawer and it is

mojhsa [17]

Answer:

The probability is $1$ .

Step-by-step explanation:

We have a drawer that contains :

Six white socks
Three brown socks
Seven black socks

Let's define the following events :

W : '' The sock we got was white ''

Br : '' The sock we got was brown ''

Bl : '' The sock we got was black ''

We can calculate the following probabilities by counting :

$P(W)=\frac{6}{16}$

Because there are 6 white socks out of 16 socks in the drawer

Using the same reasoning :

$P(Br)=\frac{3}{16}$

$P(Bl)=\frac{7}{16}$

Now to calculate the probability of getting at least two socks of the same color we need to think about the following :

Getting at least two socks of the same color means getting two, three or four (except the brown socks because we only have three brown socks) of the same color.

Again we can calculate the probability by counting :

$\frac{FavorableCases}{TotalCases}$

But giving that we pull out four socks, we always will get at least two socks of the same color.

In the most desfavorable case we will get one white sock, one brown sock and one black sock. And in the last extraction we will complete it with a white, brown or black sock (obtaining two socks of the same color).

Finally, all extractions of four socks will have at least two of the same color.

The probability is $1$ .

Donna donated 30% of the money from her yard sale to charity. One way to compute 30% is to multiply the amount of money from her

Kaylis [27]

Answer:

$16.05

Step-by-step explanation:

The question has been kind enough to provide the solution to you! It suggest multiplying her sales by 0.3 to find 30% of the total, in order to find how much money she donated to charity. To put this into practice:

53.5 * 0.3 = 16.05, which gives us our answer of $16.05.
