The product of the slopes of two non-vertical perpendicular lines is always -1. It is NOT possible for two perpendicular lines t

o both have a positive slope because the product of two positives is positive. So for the product of the slopes to be -1, one of the slopes must be positive and the other negative.

Answer:

<h2>True.</h2>

Step-by-step explanation:

The given statement is true, because the condition of perpendicularity is

m_{1} m_{2} =-1

Where m_{1} and m_{2} are the slopes of the lines.

If you think this through, two perpendicular lines actually have inverse directions, because one must be horizontal regarding the direciton of the other.

So, that "opposite direction" is shown by having an opposite slope, which must also have opposite sign, because remember that signs represents the orientation of the line.

For example, if the first line has slope of 3, the perpendicular line must have a slope of -1/3, which completes the result -1.

Therefore, the statement is completely true.

Answer:

It would take them 6.667 minutes to paint 50 square feet together.

Step-by-step explanation:

This is a classic work problem.  If Sam can do the job in 10 minutes, she can get done 1/10 of the job in one minute.  If you can do the job in 5 minutes, you can 1/5 of the job done in one minute.  To find out how many minutes it will take them together to paint 25 square feet, set the addition of their times equal to 1/x:

\frac{1}{10}+\frac{1}{5}=\frac{1}{x}

x is how long it takes them to get the job done together.  Find the common denominator and multiply it through be everything to get rid of the denominators altogether.  That denominator is 10x:

(10x)\frac{1}{10}+(10x)\frac{1}{5}=(10x)\frac{1}{x}

Simplify to get the simple equation x + 2x = 10 and 3x = 10.  That means that x=3 1/3.  That's how long it takes to do 25 square feet.  Double that time for 50 square feet.

What are the dimensions of a 2x4x8
Vlad [161]

Answer:   Many of you know this, but why is this a thing? You don't go to Subway and pay for a $5-footlong expecting to get 11 inches (although many of you will argue this is the case). And it's not just a 2x4: A 1x4 is actually ¾ inches by 3-½ inches; a 4x4 is actually 3-½ inches by 3-½ inches.
