Answer:
Option C.
Step-by-step explanation:
A perpendicular line to 2/3 will be the reciprocal and negative of this fraction. Therefore:
Slope of perpendicular line = -3/2.
Remember, the equation for solving for the slope is:
We must find points that when plugged into this equation, equal to -3/2.
Plugging in the points in option A:
Option B:
Option C: This is the correct answer.
Option D:
If Both carpenters working together hours or 2.1 hours will take to build one shed.
Step-by-step explanation:
The given is,
First carpenter estimates that it will take him 3 hours to build a shed
Other carpenter estimates it will take him 7 hours to build a shed
Step:1
Formula to find 1 hour work of carpenters (Ref. Dr. R.S. Aggarwal book)
One hour's work =
Where, n - Number of working hours
From the given,
First carpenters one hour work =
Other carpenters one hour work =
If both are working together,
One hour work of both carpenters =
=
One hour work of both carpenters
First carpenter and second carpenter will complete to build the shed in
= hours =
hours
Result:
If Both carpenters working together hours or 2.1 hours will take to build one shed.
