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.
12xy i think lol :) hope that helps a bit
The product of two radicals is equal to the radicand. The square root deletes itself.
So the result is y^3
The length of side c would be 8.
Step-by-step explanation:
Given that,
a = 4
b = 6
cosC = -1/4
If we are given two sides and angle, the law of Cosines can be used to find the third side:
By inserting the values in the formula, we get
c = 8.
Therefore, the length of side c would be 8.
Perpendicular bisectors help you find the centroid; altitudes help find the orthocenter. This is all in a triangle.
