For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in $. The solution is as follows:

$560/troy ounce * 1 troy ounce/480 grains * 1 grain/64.8 mg * 1000 mg/1 g * 1 g = $18

You purchased concentrated cleaner that must be diluted (watered down)
abruzzese [7]

Answer:

The volume of the concentrated 80 gallons mixture is 20 gallons

The volume of water in the 80 gallons mixture is 60 gallons

Step-by-step explanation:

The given parameters are;

The content of Container A = The cleaner

The concentration of the cleaner = 20% solution

The content of Container B = Pure water

The concentration of the desired solution = 5%

The volume of the required solution = 80 gallons

Let x represent the volume of the concentrated solution and y represent the volume of water in the 80 gallons mixture

Therefore, we have;

20/100 × x + y×0 = 5/100×80

x + y = 80

y = 80 - x

20/100 × x + (80 - x)×0 = 5/100×80

0.2·x = 4

x = 4/0.2 = 20

x = 20 gallons

y = 80 - x = 80 - 20 = 60

y = 60 gallons

The volume of the concentrated solution (80 gallons mixture) = x = 20 gallons

The volume of water in the 80 gallons mixture = y = 60 gallons.

Divide £88 between Bill and Sam. If Sam gets
Lynna [10]
<h3>Answer:  £66</h3>

Your teacher may want you to leave off the pounds sign.

==========================================================

Explanation:

x = amount Bill gets

3x = amount Sam gets, because he gets three times as much

x+3x = 4x = total amount of money

4x = 88

x = 88/4

x = 22

Bill gets £22

3x = 3*22 = 66

Sam gets £66

Note that 22+66 = 88 to help confirm the answer.
