we know that
If two lines are perpendicular, then the product of their slopes is equal to minus one
so
[tex]m1*m2=-1[/tex]
In this problem we have
[tex]m1=\frac{2}{3}[/tex]
Substitute in the formula and solve for m2
[tex]\frac{2}{3}*m2=-1[/tex]
[tex]m2=-\frac{3}{2}[/tex]
therefore
the answer is
The slope is equal to [tex]-\frac{3}{2}[/tex]

What is the common ratio for this geometric sequence?
Answer:
Common ratio for the sequence is 3
Step-by-step explanation:
Given sequence is

2. During a 5-day training at your department, the number of visitors tripled each day. If the training started on a Monday with 345 attendees, what was the attendance on Thursday?
The number of attendance on Thursday would be 9,315.
Given that,
During a 5-day training at your department, the number of visitors tripled each day.
Here, the training started on a Monday with 345 attendees.
Hence, the number of visitors on Tuesday is 3 times with 345 attendees.
That is, On Tuesday;
Number of attendees = 345 x 3
= 1,035
On Wednesday;
Number of attendees = 1,035 x 3
= 3,105
On Thursday;
Number of attendees = 3,105 x 3
= 9,315

It takes 54 minutes for 4 people to paint 6 walls. How many minutes does it take 6 people to paint 7 walls?
Answer:
It will take 42 minutes.
Step-by-step explanation:
In order to solve this we first have to calulate how long will it take one person to paint one wall:
54/6=9minutes
That is between 4 people it will take 9 minutes to paint a wall, one person alone supposing they all work at the same rate will take 36 minutes.
Now we just multiply that by the number of walls to be painted:
36*7=252
And we divide that by the number of people painting:
252/6=42
So it will take 42 minutes to paint 7 walls with 6 people painting.

Option B is correct
The median of the following string of values is 52
Step-by-step explanation:
Median defined as the median is the middle number.
To find the median of the following string of values:
55, 18, 58, 49, 8, 77, 62, 26, 7, 91
Arrange the string of values from least to greatest.
7, 8, 18 , 26, 49, 55, 58, 62, 77, 91
As you can see that we have two numbers, there is no middle number.
Simply, take the mean of the two middle numbers.
then;
Median = [tex]\frac{49+55}{2} = \frac{104}{2} = 52[/tex]
Therefore, the median of the following string of values is 52

The floor of a one-story building is 14 feet longer than it is wide. The building has 1715 square feet of floor space. Find the length l and width w of the floor.
Final answer:
To find the floor dimensions of a building that is 14 feet longer than it is wide with an area of 1715 sq ft, we solve the quadratic equation w * (w + 14) = 1715, resulting in w=100 feet and length l=114 feet.
Explanation:
The student is asked to find the length (l) and width (w) of a one-story building floor which is 14 feet longer than it is wide, with a total area of 1715 square feet. To solve this, we set up an equation where w represents the width and w + 14 feet represents the length. Since the area of a rectangle is length times width, the equation is w * (w + 14) = 1715.
After solving this quadratic equation, we find that w=100 feet which makes the length l = w + 14 = 114 feet. Therefore, the actual dimensions of the building are 114 ft by 100 feet.
