Answer:
11 L of 20% juice and 4 L of 5% juice
Step-by-step explanation:
Let
x L = amount of 20% juice
y L = amount of 5% juice
<u>20% juice:</u>
Amount = x L
Amount of juice L
<u>5% juice:</u>
Amount = y L
Amount of juice L
<u>16% juice:</u>
Amount = 15 L
Amount of juice L
We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so
and
From the first equation:
Substitute it into the second equation:
There's a 1/10 chance of drawing the yellow card once. Putting it back in the deck doesn't change this probability on the second draw. So the probability of drawing it twice is (1/10)(1/10) = 1/100

Answer: 15 & 2/3</h3>
=======================================================
Explanation:
Use a calculator or long division to find that 47/3 = 15.667
Erase the decimal portion to get 15
Then note how 15*3 = 45, which is 2 short of 47.
This means 47/3 = 15 remainder 2.
The remainder 2 portion forms the numerator of the fractional part of the mixed number.
The improper fraction 47/3 converts to the mixed number 15 & 2/3
---------------
Here's another way to do the problem
47/3 = (45+2)/3
47/3 = 45/3 + 2/3
47/3 = 15 + 2/3
47/3 = 15 & 2/3
Im pretty sure it is D :)
