Obi's age is twice oba's age 4 years ago obi was three times as old as oba. find their ages​
frutty [35]

Answer:

Obi's age is 18 and Oba's age is 9

Step-by-step explanation:

Let Obi's age be x and Oba's age be y

<u><em>Condition 1:</em></u>

x = 2y -----------(1)

<u><em>Condition 2:</em></u>

(x-4) = 3(y-4)

=> x -4 = 3y-12

=> x - 3y = -9  -----(2)

<u><em>Putting eq (1) in (2)</em></u>

2y - 3y = -9

=> -y = -9

=> y = 9

Now,

x = 2y

=> x = 2(9)

=>  x= 18

Answer:

320 ft²  (nearest whole number)

Step-by-step explanation:

Given:

  • height of fence post = 8 ft
  • diameter of fence post = 1 ft  ⇒  radius = 0.5 ft
  • total number of posts = 12
  • π = 3.14

Surface area of a cylinder = 2πr² + 2πrh

⇒ SA of one fence post = 2 · 3.14 · 0.5² + 2 · 3.14 · 0.5 · 8

                                       = 1.57 + 25.12

                                       = 26.69 ft²

As there are 12 fence posts,

Total paint needed = 12 × 26.69

                                = 320.28 ft²

                                = 320 ft² (nearest whole number)
