Answer:
$333.33
Step-by-step explanation:
This question is a little bit confusing, but I am assuming you mean to say that the 72% of the total pay, which is the amount he took home, is $240. So, then you can set up a proportion to solve the problem.
72
Then, you multiply the proportion out, getting
multiply the right side out and then divide by 72 to get $333.33
So, Both lines are perpendicular
Step-by-step explanation:
We need to identify if lines:
Line 1: (8,12)(7,-5)
Line 2: (-9,3)(8,2)
are parallel, perpendicular, or neither?
- Lines are parallel if they have same slopes i.e slope 1= slope2
- Lines are perpendicular if their slopes are negative inverses of each other i.e slope 1= -1/slope 2
The formula used to find slope is:
Finding Slope of Line 1:
The points are: Line 1: (8,12)(7,-5)
Putting values in the formula:
So, Slope of line 1 is 17
Finding Slope of Line 2:
The points are: Line 2: (-9,3)(8,2)
Putting values in the formula:
So, Slope of line 2 is
Since
So, Both lines are perpendicular
