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
Step-by-step explanation:
There can only be 2 location which is to the right and to the left, this is because it means the difference between is 9. So the two answers are…
13
And
-13
The answer is false
if you solve both sides it says that 627.25 is less than 3.714 which isn't correct because 627.25 is obviously greater than 3.714
First one: x <= -1
Second one: x > 4/3
Since you logically OR them together, the answer will be simply the combination of them two:
x <=-1 or x> 4/3
