9v you just combine like terms
Answer:
its exact form is -1/8
its decimal form is -0.125
Step-by-step explanation:
you do the math to the fractions accordingly and then simplify your answer to whichever form
if they had spend 1500 total for goods and expenses 500 which is total 2000 and
revenue is 3000
1500 + 500 - 3000 = 1000 is profit for the business
<h3>The amount of Chlorine (A) to add to a basin is 112590000000</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>A wastewater treatment operator uses the formula:</u></em>
![A = 8.34 \times FC](https://tex.z-dn.net/?f=A%20%3D%208.34%20%5Ctimes%20FC)
Where,
A = amount of chlorine to add to basin
The flow through the basin is Fand the concentration of Chlorine to water is C
From given,
F = 1800
C = 7, 500, 000
To find: A
![A = 8.34 \times 1800 \times 7500000\\\\A = 15012 \times 7500000\\\\A = 112590000000](https://tex.z-dn.net/?f=A%20%3D%208.34%20%5Ctimes%201800%20%5Ctimes%207500000%5C%5C%5C%5CA%20%3D%2015012%20%5Ctimes%207500000%5C%5C%5C%5CA%20%3D%20112590000000)
Thus amount of Chlorine (A) to add to a basin is 112590000000
