Surface = 2 x PI x r x H + 2 x PI x r^2

= 2 x r x h + 2 x r^2

= 2 x 6 x 12 + 2 x 6^2

= 144 + 72
 = 216 PI in^2

Find two numbers given that their sum is 60 and
likoan [24]

Answer:

12 and 48

Step-by-step explanation:

let n be the larger number , then \frac{1}{4} n is the smaller number and their sum is

x + \frac{1}{4} x = 60 ( multiply through by 4 to clear the fraction )

4x + x = 240 , that is

5x = 240 ( divide both sides by 5 )

x = 48

smaller number = \frac{1}{4} × 48 = 12

The 2 numbers are 12 and 48

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other. Find the length of the other piece
sergeinik [125]

Answer:

The length of the other piece is 38 inch.

Step-by-step explanation:

Given:

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.

Now, to find the length of the other piece.

Let the length of the other piece be x.

And the length of one piece be 4x.

The total length of the pipe = 190 inch

According to question:

4x+x=190

⇒5x=190

<em>Dividing both sides by 5 we get:</em>

⇒x=38

Therefore, the length of the other piece is 38 inch.

When does the proportion form of newton's second law take the form of an equation?
Brrunno [24]
Newton's law of motion has three parts. The second of which states that the force needed to move an object is directly proportional to the acceleration of the motion. The proportion can be written as,
              F = ka
where k is the constant of proportionality. This can be substituted with the mass of the object such that the equation would become. 
                F = ma
where F is force, m is mass, and a is acceleration.
