When a negative number is divided by another negative number, <span>sign of the quotient would be positive and always positive</span>
Answer:By definition, perpendicular line are two lines that intersect at right angles. In other words, the angle made by two lines should be 90°. Therefore, the use of distance formula does not help because it only tells you if the sides are equal. It does not tell you about the intercepted angle.
A technique that can help you to know if two straight lines are perpendicular is is you find their slopes. Let's say the slope of line 1 is m1 and the slope of line 2 is m2. If m1*m2 yields a product of -1, then the lines are perpendicular. This is because if m1 is the negative reciprocal of m2, the lines are perpendicular. But if m1=m2, the lines are parallel, meaning they don't intersect at all.
Therefore, the answer is: Find the slopes and show that their product is -1.

55 because 55 divided by 18 is 32%. Hope this helped!
Answer:
There are approximately 1145 vehicles are stuck in the traffic jam. It is very close to option C.
Step-by-step explanation:
To determine:
Estimate how many vehicles are stuck in the traffic jam.
Information Fetching and Solution Steps:
- On a residential single lane road there was a wreck that backed up traffic for 4 miles.
- 70% of the traffic consists of cars and 30% of the traffic consists of trucks.
- The average distance between vehicles is 3 feet.
- The average length of a car is 13.5 feet.
- The average length of a truck is 20 feet.
- There are 5280 feet in 1 mile
Let 'n' be the total number of vehicles stuck in the traffic jam.
So, the equation becomes
Estimating to get the integer vehicle number and rounding it to the nearest integer.
vehicles
Therefore, there are approximately 1145 vehicles are stuck in the traffic jam, which is very close to option C.

<span>For me,
It would be a rational decision if the first worker was more than twice as productive as the second worker.</span>
This can happen in real life, for example 2 workers are hired to do the same type of job but one worker graduated with honors, the company can give a higher pay to the worker with honors compared with the other one who graduated.
It is up to the company on how much they would pay their workers as long as it is above the minimum wage. Though there might be hurt feelings among the workers if they each knew how much they are paid for, it is also better for the company to inform workers that they are paid this certain amount because of the following reasons (graduated w/ honors).
