14g zinc
Step-by-step explanation:
To get the mass of zinc in the metal bar, you can multiply the percentage of zinc by the total mass.
40g x .35 = 14g zinc
Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,

Hence, this is the required solution.
Answer:
The answer is No.4
Step-by-step explanation:
Giventhat the formula of a cube is, V = x³ where x determine the length of the edge of the cube. By using this formula, you may find out the volume of a rubix cube :
x = 5.7cm
V = 5.7³
= 185.193cm³
The question ask us to find the volume of 2 combined cubes so, we can just multiply it by 2 :
V = 185.193 × 2
= 370.386cm³
It is C a pyramid! They ask for shape but no measurements
