Answer:
Perimeter = 317 m
Step-by-step explanation:
Given track is a composite figure having two semicircles and one rectangle.
Perimeter of the given track = Circumference of two semicircles + 2(length of the rectangle)
Circumference of one semicircle = πr [where 'r' = radius of the semicircle]
= 25π
= 25 × 3.14
= 78.5 m
Length of the rectangle = 80 m
Perimeter of the track = 2(78.5) + 2(80)
= 157 + 160
= 317 m
Therefore, perimeter of the track = 317 m
For example:
(4/9) x=8
Now can solve this equation multiplying each side by 9/4.
(9/4)(4/9)x=(9/4)8
x=18
To check:
(4/9)(18)=(4*18)/9=72/9=8
Answer:
-6.67 im pretty sure
Step-by-step explanation:
4+5=9
9-6=3
3/7=0.43
0.43-7=-6.67
the calculator says sum else but like who cares right? lol

Lola used 3/4 more ink cartridges than her friends
Step-by-step explanation:
Answer:
x + x + 2
Step-by-step explanation:
cuz if its consecutive odd then its every 2 numbers so if x = 3 then you add two to x
