One canned juice drink is 20% orange juice, another is 5% orange juice, how many liters of each should be mixed together in orde
gavmur [86]

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 =0.2x L

<u>5% juice:</u>

Amount = y L

Amount of juice =0.05y L

<u>16% juice:</u>

Amount = 15 L

Amount of juice =0.16\cdot 15=2.4 L

We mixed x L of 20% juice with y L of 5% juice to get 15 L of 16% juice, so

x+y=15

and

0.2x+0.05y=2.4

From the first equation:

x=15-y

Substitute it into the second equation:

0.2(15-y)+0.05y=2.4\\ \\20(15-y)+5y=240\\ \\300-20y+5y=240\\ \\-20y+5y=240-300\\ \\-15y=-60\\ \\15y=60\\ \\y=4\ L\\ \\x=15-4=11\ L

a square measuring 9 inches by 9 inches is cut from a corner of a square measuring 15 inches by 15 inches. what is the area of t
AVprozaik [17]
First, find the area of each figure. Then subtract the smaller area from the larger area. Your work should look something like this:

A = l * w
A = 9 * 9
A = 81

This is the area of the smaller square. Now find the area of the larger square. 
A = l * w
A = 15 * 15
A = 225

Now subtract the two areas to find the area of the shape that is left when the smaller square is cut out. 

225 - 81 = 144 

Your final answer should be:
144 in^2
