11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.
The number of small tiles are needed is 300 tiles.
<h3>Number of tiles needed</h3>
Using area of rectangular formula
Area of the room = length(l) × breadth (b)
Area of the room=300 cm×180 cm
Area of the room=54,000 cm²
Number of tiles needed = Area of rectangular region / Area of one tile
Number of tiles needed=54,000/180
Number of tiles needed=300 tiles
Therefore the number of small tiles are needed is 300 tiles.

Answer:
<u>z = -4</u>
Step-by-step explanation:
<u>Given</u> :
- x = -2
- y = -5
- z divides xy in the ratio 2 : 1 (m : n)
<u>Solving</u> :
- Take the section formula
- z = [my + nx] / [m + n]
- z = [2 x -5 + 1 x -2] / [2 + 1]
- z = -10 - 2 / 3
- z = -12 / 3
- <u>z = -4 </u>
