Answer:
Here is the missing part.
Cups and liters:-1 litre = 2.1 cups
Cups and pints:- 1 pint = 2 cups
Pints and liters:-1 litre = 2.1 pints
Step-by-step explanation:
Step 1:
7 cups + 3 liters = 9.8 pints
5 liters - 9 cups = 6 pints
Cups and Liters
(put in equation 2)
1 Liter = 2.1 Cups.
Step 2:
Cups and Pints
(put in equation 2)
1 Pint = 2 Cups.
Step 3:
Pints and Liters
(put in equation 2)
1 Liter = 2.1 Pints.
The amount of acid in the solution is obtained by multiplying the volume by the percent acid composition of the solution.
amount of acid = volume x percent composition
Substituting,
amount of acid = (5 L) x (0.20) = 1 L
Therefore, the answer of 1L.
I don't know if you know something called PEMDAS
Parentheses
Exponent
Multiply
Divide
Add
Subtract
So you would do the -2(-7) first giving you 14
So now we have -62/12 +14
now you would do -62/12 giving you -5.16666667
and now the equation is -5.16666667 + 14 = 8.83333333
I know for a fact, being in Calculus Honors, that what I did to simplify is correct. Using the Order of Operations, or PEMDAS (Commonly remebered as "Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".) to simplify this answer is necessary.
If your teacher wrote this problem please inform him or her of Order of Operations before your classmates use it even though its wrong.</span>
