Answer:
0.4kg, 1.4kg and 1.8kg
Step-by-step explanation:
Given parameters:
Mass of alloy = 3.6kg
Ratio of elements in the alloy = 2:7:9
Unknown:
Mass of each element in the alloy = ?
Solution:
To find the mass of each element in the alloy, first find the sum of the ratio;
2+7+9 = 18
Mass of nickel =
x 3.6 = 0.4kg
Mass of zinc =
x 3.6 = 1.4kg
Mass of copper =
x 3.6 = 1.8kg
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
Answer:
try 7,920 miles
Step-by-step explanation:
I just took 8,578 - 658 and got 7,920.
169 needs to be into four parts, by which 2 sides multiply to 169. The sides would be 13 each, that way 13×13=169. You would then subtract 6m from the 13m, which gives you 7 as your answer!
Answer: 7m
