Step-by-step explanation:
8-13=s+4s
-5=5s
-5/5=5s/5
-1=s
Answer:
P=40
Step-by-step explanation:
find the distance between each vertices:
between the following points to find the length of each sides, octagon has 8 sides , since it is regular pentagon the distance between each vertices =5
the length of each side of octagon=5
to check :d=√(x2-x1)²+(y2-y1)²
(-2,-4) and (1,0) , d=√[(1-(-2)]²+(0+4)² =√3²+4², d=5
(1,0) and (1,5) , d= 5
(1,5) and (-2,9) , d=5
(-2,9) and (-7,9) , d=5
(-7,9) and (-10,5) , d=5
(-10,5) and(-10,0) , d=5
(-10,0) and(-7,-4), d= 5
(-7,-4) and (-2,-4), d=5
perimeter of octagon = 8a ( a is the length of the side)
p=8(5)
P=40
Make bototm number same
3/10 times 13/13=39/130
4/13 times 10/10=40/130
A.
39/130 and 40/130
they are 1/130 apart
B.
a ratioal number between
39/130=390/1300
40/130=400/1300
between 390/1300 and 400/1300
any number from 391/1300 to 399/1300 example 395/1300
Y>3/5x-1.5. Its only 'or equal to' if the line is bold and not dashed. The shaded area is above the line so it's greater than. Hope this helped!
Answer:
20-5 11/12= 9 11/12
Step-by-step explanation:
we do (3 2/3 + 2 1/4+ 2 1/3 )which is
3 8/12. 2 3/12 2 4/12 (common denominator)
then add 3 8/12 and 2 3/12 and 2 1/3 to get 10 1/12 then we get 20- 10 1/12 to get a final answer of 9 11/12
