Gnesinka [82]

Answer:

(A)398 cubic inches

Step-by-step explanation:

Given a cylindrical piece of iron pipe with the following dimensions:

  • Height = 12 inches
  • Diameter = 8 inches

Therefore: External radius =4 Inches

Since the wall of the pipe is 0.75 inch thick,

Internal Radius =4-0.75 =3.25 Inches

Volume of a Cylinder = \pi r^2 h

Inside Volume of the Pipe

= \pi*3.25^2*12\\=398$ cubic inches

The correct option is A.

Phoenix [80]

Answer:

The sequence converges to 1

Step-by-step explanation:

Given

\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},...

Require

Description of the sequence

The given sequence follows:

\frac{2}{4}. \frac{3}{5}, \frac{4}{6}, \frac{5}{7},... \frac{n+1}{n+3}

i.e.

T_n = \frac{n+1}{n+3}

For every term,

\frac{n+1}{n+3} < 1

In other words,

as the value of n increases, \frac{n+1}{n+3} approaches 1

<em>Hence, (c) is true</em>

yKpoI14uk [10]

Answer:

The Answer is:

Step-by-step explanation:

First, find the 20% that he must pay:

$3,500 * .20 = $700.

The remaining balance is:

$3,500 - $700 = $2,800

He already paid $1,000 of his deductible of $2,000. He has $1,000 left to pay.

Add that to the $700 to get:

$1,000 + $700 = $1,700 out of pocket.
