leonid [27]
The answer is 36. I know this because since one of the lengths of the room is 8, you take 80 and divide it by 8 which gives you 10. So now that you know the two side lengths you add. 10+10+8+8 which is 36.

What is the slope of the line through (-2, 5) and (4, 9)?
Volgvan




The slope of the line is

(9-5) / (4- -2) = 4/6 = 2/3 .


If the x-intercept is -2 and the y-intercept is 1, then the equation of the line is

y = 1/2 x + 1 .

None of the choices is correct.

The difference between interior angle in centesimal measurement and sexagesimal measurement is 15° of a regular polygon. Find th
DaniilM [7]

Answer:

8

Step-by-step explanation:

x = centesimal angle (100 degrees in a right angle)

y = sexagesimal angle (90 degrees in a right angle)

x - y = 15

x×90/100 = y

x×9/10 = y

x - x×9/10 = 15

10x/10 - 9x/10 = 15

x/10 = 15

x = 150

y = 150×9/10 = 15×9 = 135

using centesimal system :

the sum of all external angles in a polygon is 400 degrees (a full circle).

one external angle is the complement of one internal angle to 200 degrees = 200-150=50 degrees.

to find the number of sides of the polygon we need to find the number of angles or corners. and that is how many external angles fit into the full circle.

n = 400/50 = 8

the polygon has 8 sides
