6 pints of 20% pure fruit juice and 24 pints of 45 % pure fruit juice is mixed to get 30 pints of mixture of 40 % pure fruit juice
<em><u>Solution:</u></em>
The final volume is 30 pints of mixture of 40 % pure fruit juice
Let "x" be the volume of 20 % pure fruit juice
Then, (30 - x) is the volume of 45 % pure fruit juice
Then, we can say,
"x" be the volume of 20 % pure fruit juice and (30 - x) is the volume of 45 % pure fruit juice is mixed to get 30 pints of mixture of 40 % pure fruit juice
<em><u>Therefore, we frame a equation as:</u></em>
<em><u>Solve the above expression for "x"</u></em>
So, 6 pints of 20% pure fruit juice
Then, (30 - x) = 30 - 6 = 24
24 pints of 45 % pure fruit juice is used
Answer:
Step-by-step explanation:
WX = 23 – 2x,
TV = 64 – 10x,
First, create an equation you will use to find the value of x.
Thus:
(midsegment theorem of a ∆)
(substitution)
Multiply both sides by 2
Collect like terms
Divide both sides by -6
Find TV:
Plug in the value of x
Answer:
You can toss 4 coins 55 times.
Step-by-step explanation:
Each coin would represent a child as there is an equal chance for a boy and girl, like the chance of heads and tails are equal.
You toss it 55 times as the question asks for 55 trials.
