Answer:
C. O.5s
Step-by-step explanation:
If the wave length is 100m and it goes at a speed of 200m/s then it will only take 0.5 seconds because 100 is half of the speed of 200
Answer:
Exact form: 
Decimal form: 
The solution for x is: The solution for x is of 10.455º
Step-by-step explanation:
We are given the following equation:
Placing into the desired format, the exact format is:
In the decimal part, we divide 8 by 9. So
Solving for x:
We apply the inverse sine. So
The solution for x is of 10.455º
Since, the system of linear equations are parallel
so, they will never cross or intersect each other
And we know that
solution can only be found if both lines intersect atleast one point
But here , lines are parallel
so, they never intersect each other throughout number line
Since, they never intersect
so, we won't get any common value between both lines
Hence,
There is no solution...........Answer
The solution is: 252. 14x18
