Answer:the cost of renting one chair is $2.25
the cost of renting one table is $8.25
Step-by-step explanation:
Let x represent the cost of renting one chair.
Let y represent the cost of renting one table.
The total cost to rent 3 chairs and 5 tables is $48. This means that
3x + 5y = 48 - - - - - - - - - -1
The total cost to rent 6 chairs and 2 tables is $30. This means that
6x + 2y = 30 - - - - - - - - - -2
Multiplying equation 1 by 6 and equation equation 2 by 3, it becomes
18x + 30y = 288
18x + 6y = 90
Subtracting, it becomes
24y = 198
y = 198/24 = 8.25
Substituting y = 8.25 into equation 1, it becomes
3x + 5 × 8.25 = 48
3x + 41.25 = 48
3x = 48 - 41.25 = 6.75
x = 6.75/3 = 2.25
Answer: 30 is 53

Answer:
AB ≈ 11.17 m
Step-by-step explanation:
The arc AB is calculated as
AB = circumference of circle × fraction of circle
= 2πr × ![\frac{80}{360}](https://tex.z-dn.net/?f=%5Cfrac%7B80%7D%7B360%7D)
= 2π × 8 × ![\frac{8}{36}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B36%7D)
= 16π × ![\frac{2}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B9%7D)
=
≈ 11.17 m ( to the nearest hundredth )
