A scientist mixes water (containing no salt) with a solution that contains 35 % salt. She wants to obtain 245 ounces of a mixtur

Elenna [48]

Answer:

Answer. 105 ounces of water is needed.

Let W = the volume of water to be mixed in ounces).

Then the volume of the 30% salt solution needed is (210-W).

The balance equation for the salt mass is

0.3*(210-W) = 0.15*210.

Simplify and solve for W:

63 - 0.3W = 31.5,

63 - 31.5 = 0.3W,

0.3W = 31.5,

W = 31.5%2F0.3 = 105.

Answer. 105 ounces of water is needed.

Darina [25.2K]

Answer:

Last year Dr. Potter give<u> 32 </u>Polio vaccination and <u>28</u> measles vaccination.

Step-by-step explanation:

Given:

Each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.

Last year ,Dr. Potter gave a total of 60 vaccinations that consisted of a total of 184 doses.

Now, to find the number of polio vaccinations and many measles vaccination.

Let the number of Polio vaccination be $x.$

And let the number of measles vaccination be $y.$

So, the total number of vaccinations:

$x+y=60$

$y=60-x$ .......(1)

<em>As, given each Polio vaccination consists of 4 doses , and each measles vaccination consists of 2 doses.</em>

Thus, the total number of doses:

$4x+2y=184$

Substituting the value of $y$ from equation (1):

$4x+2(60-x)=184$

$4x+120-2x=184$

$2x+120=184$

<em>Subtracting both sides by 120 we get:</em>

$2x=64$

<em>Dividing both sides by 2 we get:</em>

$x=32.$

<em>The number of Polio vaccination = 32.</em>

Now, putting the value of $x$ in equation (1):

$y=60-x$

$y=60-32$

$y=28.$

<em>The number of measles vaccination = 28.</em>

Therefore, last year Dr. Potter give 32 Polio vaccination and 28 measles vaccination.
