U use the slope formula
slope = (y2 - y1) / (x2 - x1)

and u label each set of points :
set 1 : (2,-6)...x1 = 2 and y1 = -6
set 2 : (-3,-4)...x2 = -3 and y2 = -4

now u sub...pay attention to ur signs
slope = (-4 - (-6) / (-3 - 2) = (-4 + 6) / -5 = 2/-5 = -2/5

The floor of a gazebo is in the shape of a regular octagon. The perimeter of the floor is 72 feet. The distance from the center
Katyanochek1 [597]
The length of one side of the octagon is given by:
 L = 72/8&#10;&#10;L = 9
 Then, the apothem can be determined using the Pythagorean theorem in the following way:
 11.8 ^ 2 = (9/2) ^ 2 + a ^ 2&#10;
 Clearing to have:
 a ^ 2 = 11.8 ^ 2 - (9/2) ^ 2
 a = \sqrt{11.8 ^ 2 - (9/2) ^ 2}
 a = 10.91
 Then, the area is given by:
 A = (8) * (1/2) * (L) * (a)&#10;
 Where,
 L: length of the octagon sides
 a: apotema
 Substituting values:
 A = (8) * (1/2) * (9) * (10.91)&#10;&#10;A = 392.76 feet ^ 2
 Answer:
 
the approximate length of the apothem is:
 
a = 10.91 feet
 
The approximate area of the floor of the gazebo is:
 
A = 392.76 feet ^ 2

When Aristotle Proclaimed his new theory, 87 responded. If this was only 3/5 the number of responses expected, how many response
Genrish500 [490]
3/5 of the total responses expected = 87...
3/5x = 87
x = 87 / (3/5)
x = 87 * 5/3
x = 435/3
x = 145 <=== what was expected

What percent of 40 is 16?
kotegsom [21]

Answer: E. 40

Step-by-step explanation:

<u>Concept: </u>

- When you encounter questions that state "what percent of [a] is [b]"  then it means asking for a fraction of b to a, which is "(b/a)×100%".

- If you are still confused, I would provide some examples

  • What percent of 20 is 5: (5/20)×100% = 25%
  • What percent of 10 is 2: (2/10)×100% = 20%

---------------------------------------------------------------------------

<u>Solve:</u>

(16/40)×100% = 0.4 × 100% = 40%

Hope this helps!! :)
