Answer:

7 1/2 cups

Step-by-step explanation:

20 gallons is ten times 2 gallons.

Ten times the amount of water will require ten times the disinfectant (we assume).

... 10 × 3/4 cup = 30/4 cups = 7 1/2 cups

If FC IS RS 4430 and the BEP in unitsis 89, then contribution margin is ?
Umnica [9.8K]

Answer: RS 49.8

Step-by-step explanation:

Given the following :

Fixed cost = RS 4430

Break even point = 89 units

Recall:

Break even point in units = Fixed cost ÷ contribution margin

Therefore,

Contribution margin equals;

(Fixed cost ÷ break even point in units)

= 4430 / 89

= 49.775280

= RS 49.8

If m and n can be any integers such that n<4 and 4m - 3n < 20, which of following is the solution set for m?A m <7.25B
soldier1979 [14.2K]

If we multiply the inequality n<4 by 3 we get the following:

(n

Now, on the next inequality we have the following:

\begin{gathered} 4m-3n

By transitive property, we have:

\begin{gathered} 3n

therefore, the solution set for m is m<8

Write the equation y= -1/3x -5 in standard form.
melomori [17]

Answer:

Standard form is another way to write slope-intercept form (as opposed to y=mx+b). It is written as Ax+By=C. You can also change slope-intercept form to standard form like this: Y=-3/2x+3. Next, you isolate the y-intercept(in this case it is 3) like this: Add 3/2x to each side of the equation to get this: 3/2x+y=3.
