This questions expects us to SOLVE for S, i.e. express the the value of S in terms of other variables, and simplify the answer, if necessary.
We need s to be the subject (on the left hand side), so we need to isolate s.
C=(1/3)m(s+b)
First step, cross multiply to rid of numerical fractions.
C/1=(m(s+b))/3 -> 3C=m(s+b)
If there is a multiplier that does not contain s, divide both side by the multiplier.
3C/m = (m/m)(s+b) -> 3C/m = s+b
We're nearly done. We need to isolate s, so subtract "extra" terms from the side containing s, i.e. subtract b from both sides:
3C/m - b = s + b -b -> 3C/m-b = s
We almost there, but customary practice is to put s on the left-hand side of the equal sign, so just swap sides:
3C/m-b = s -> s=3C/m - b
and that's the answer:
s=3C/m - b
Answer:
Option B - 9 hours
Step-by-step explanation:
Given : Three machines operating independently, simultaneously, and at the same constant rate can fill a certain production order in 36 hours. If one additional machine were used under the same operating conditions.
To find : In how many fewer hours of simultaneous operation could the production order be filled?
Solution :
Let the numbers of hours taken including additional machine i.e. 4 machines be 'x' hours.
So, 3 machines take 36 hours
and 4 machines take x hours.
Then,
i.e. 4 machines spend 27 hours to do work.
Number of fewer hours of simultaneous operation could the production order be filled is given by,
hours
Therefore, the work could be done in 9 hours less.
So, the correct answer is B.
we are given
graph of a quadratic function
Quadratic function:
Those function which has degree=2
we can write it as
Since, the degree is 2
so, the shape of the curve will be parabolic
so, option-B.........Answer
