Answer:
the apprentice can complete the job in 30 hours by working alone.
Step-by-step explanation:
Given:
Number of hours required to complete a job by welder = 18 hours
Number of hours welder work on job = 6 hours.
Number of hours required by apprentice to complete the job = 14 hours
We need to find Number of hours required to complete a job by apprentice alone.
Solution:
Let Number of hours required to complete a job by apprentice alone be 'a'.
Also let the job completed be = 1
Now we know that ;
Time required on job is equal to sum of Number of hours welder work on job and Number of hours required by apprentice to complete the job.
framing in equation form we get
Time required on job =
Now we can say that;
each has done a fraction of the work so we will add to two fraction as number of hours of work done by Total number of hours required to do the work to complete 1 job.
so we can frame the equation as;
By reducing the fraction we get;
Now we will make the denominator common to solve the fraction we get;
Now denominators are same so we will solve the numerator we get;
Multiplying both side by 3a we get;
Combining the like terms we get;
Dividing both side by 2 we get;
Hence the apprentice can complete the job in 30 hours by working alone.

Step-by-step explanation:
Area of parallelogram = Base x height
If two parallelograms are similar, then their corresponding sides are proportional.
That means,
Hence,
Answer:
f(25/29) =
Step-by-step explanation:
In order to do this problem, we need to plug in for x. When we plug it in we get
. After this we can start by multiplying. When we multiply
we get
. Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us
because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of
.
