In 1 second the object fell 144 - 128 = 16 feet.
From 2 seconds to 1 second the object fell 128 - 80 = 48 feet.
From 2 seconds to 3 seconds the object fell 80-0 = 80 feet.

The distance the object fell increased with time.

 The correct answer would be the last one.

Namely, what is 11.65 in percentage from 24.9

if we take 24.9 to be the 100%, let's see

\bf \begin{array}{ccllll}

\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
24.9&100\\
11.65&x
\end{array}\implies \cfrac{24.9}{11.65}=\cfrac{100}{x}

solve for "x".

A cylindrical piece of iron pipe is shown below. The wall of the pipe is 0.75 inch thick, and the pipe is open at both ends: The
const2013 [10]

Answer:

It's 398

Step-by-step explanation.

Diameter of 8.

height of 12.

8 - .75 - .75= 6.5

6.5/2 = 3.25

3.25 x 3.25 x 12 x 3.14 = 397.995

round to the nearest whole number and you get

398

Take the diameter (8) an subtract is by both sides of the walls (0.75 each wall) that gives you 6.5. Take that 6.5 and half that, because you need to have the radius to solve volume problems, giving you 3.25.  Then multiply 3.25 by 3.25 together ( I know it seems redundant but it just works easier this way) This gives you 10.5625. After that take 10.5625 then multiply it into 12, being the height, which gives you 126.75. Finally take 126.75 and multiply that into 3.14 (pie) giving you the answer.
