Assume that solution with 20% and 50% salt is x and y gallons respectively.
Therefore,
x+y = 300 => y=300-x
Additionally
20x+50y = 300*41 = 12300
Substituting for y
20x+50(300-x) = 12300 => 20x+15000-50x = 123000 => -30x = -2700
x= 90 gallons
y= 300-x = 300 - 90 =210 gallons
The answer is none I’m pretty sure
Hi There! I’m happy to help! Answer: $23.05
Step-by-step explanation:
First, since there is 3 shirts that cost $25.65, multiply them. Product is $76.95. Now, we subtract the $76.95 from the $100, making $23.05 her change. Hope this helps!
Each one of the red, green, and gold necklace have a probability of 1/3.
Each one of the red and black bracelet have a probability of 1/2.
Each one of the silver, yellow, green, gold, black, and white hat have a probability of 1/6.
The probability of Suzy choosing a red bracelet and silver hat is solved by getting the probability of the red bracelet and silver hat which is computed by:
=1/2 * 1/6
= 1/12
The probability is 1/12.
What does "the following" mean ?
Where are the choices ?
