b) How much nickel is needed to mix with 20kg of copper?
12 m
6 m
8 m
Answer:576
Step-by-step explanation:
Volume is all the sides multiplied together. 12 x 6 x 8=576
Answer:
576 m
Step-by-step explanation:
multiply all the sides together
volume= length x width x height
volume= 12 x 6 x 8
The first angle is 130.5 degrees and the second angle is 49.5 degrees. They are supplementary angles since their sum is 180 degrees.
In this problem, we're given that two angles are supplementary, which means the sum of their measures is 180 degrees. If we call the second angle x, then the first angle is described as 3x - 18, as it is 18 degrees less than three times the measure of the second angle.
We can create an equation based on this information: x + (3x - 18) = 180. Solving this equation gives us x = 49.5. That means the second angle is 49.5 degrees.
Substitute x with 49.5 degrees into the expression for the first angle: 3 * 49.5 - 18 = 130.5. Thus, the first angle is 130.5 degrees and the second angle is 49.5 degrees. Both angles sum up to 180 degrees, confirming that they are supplementary.
