Kevin uses 84 fluid ounces of water to make an all-purpose cleaner. the directions call for 4 fluid ounces of concentrated soap for every 3 cups of water. how many fluid ounces of soap should he use? ( 1 cup = 8 fl oz

using unit rates to convert measurement

He should use 14 fluid ounces of soap.

Step-by-step explanation:

1. The first step is to make the conversion from cups to ounces. Knowing that:

You get:

2. According to the information given in the exercise, Kevin must use 4 fluid ounces of concentrated soap for every 3 cups of water or 24 fluid ounces of water.

Then, knowing that he uses 84 fluid ounces of water to make an all-purpose cleaner, you can set up the following proportion:

Where "x" is the total fluid ounces of soap that he should use.

3. Solving for "x", you get this result:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
