Answer:
3 liters
Step-by-step explanation:
There's a simple and effective "visual" way to solve mixture problems that makes short work of this.
In the attached, the concentrations of the contributors are listed on the left. It can work well to put the largest contributor on top (though that is not strictly necessary). The target concentration is put in the middle between them, and the differences along the diagonals are computed.
The diagonal differences are reduced to lowest terms as a ratio in the right-hand column. These numbers can be compared to the problem statement to see how they relate.
In this case, the total is 4 L of juice, and the total of the ratio units is 4. Then the ratio units are the number of liters of the corresponding contributor:
- 3 L of 100% juice
- 1 L of 20% juice
Answer:
90.51 (rounded to the nearest hundredth)
Step-by-step explanation:
We can use trigonometry to figure this out
sin = opposite side / hypothenuse
The 45° angle's opposite side is a leg of the triangle
sin 45 = leg / 128
sin 45 * 128 = (leg / 128 ) * 128
0.7071 * 128 = leg
90.51 = leg
Answer:
If several points are graphed on a number line, the point that is farthest from 0 need NOT be always greater. Consider x axis, our Real number line. We can traverse in positive number direction and negative number direction.
