We calculate this problem as follows:
<span>3:4:13
Total mass = 4 kg
3x + 4x + 13x = 4
x = 0.2
nickel = 3x0.2 = 0.6
zinc = 4x0.2 = 0.8
<span>copper = 13x0.2 = 2.6
Hope this answers the question. Have a nice day.

Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
Hence, the rotational speed is 0.38 rotation per second.
140*.20=28
140-28= $112
so, the current price is $112
Answer:
c =
Step-by-step explanation:
a3 = -27
a5 = -162
a5 = a3 * c^2
6 = c^2
c =
