x + 77 + 47 + 2x + x = 360

4x = 236

You answer: x = 59

59+77+59+47+59+59=360

the radius of a cylindrical water tank is 6.5ft, and its height is 16ft what is the volume of the tank?​
dimulka [17.4K]

Answer:

Volume of cylindrical tank is 2122.64 cubed feet.

Step-by-step explanation:

It is given that:

Radius of cylindrical tank = 6.5 feet

Height of tank = 16 feet

Volume of tank = πr²h

Putting the values in the formula

Volume = 3.24 * (6.5)² * 16

Volume = 3.14 * 42.45 * 16

Volume = 2122.64 cubed feet.

Therefore,

Volume of cylindrical tank is 2122.64 cubed feet.

Step-by-step explanation:

√3×sinx+cosx=0

√3sinx=-cosx

√3sinx/-cosx=1

(tan(180-30))=1/√3

tan(-30)=1/√3

Therefore, x= -30

The age of Oscar is 1/3of his sister .after 12 years his age will be half that of his sister. What is Oscar's current age
Radda [10]

Answer:

Let's denote:

Age of Oscar : x

Age of Oscar's sister : y

Then, we have:

3x = y(1)

2(x + 12) = y + 12(2)

Substitute y from (1) into (2), then:

=> 2(x + 12) = 3x + 12

=> 2x + 24 = 3x + 12

=> x = 24 - 12

=> x = 12

=> Oscar's current age: 12
