Another way of finding Surface Area is

SA= 2LW+2LH+2HW

L= Length

W= Width

H= Height

the answer, and explained, would be this

2. SA= 2(12)(10)+2(12)(16)+2 (10)(16)

(multiply)

3. SA= 240 + 384 + 320

(add)

The answer is..

SA=944ft3

A hotel wants to put a fence around a circular spa. The radius of the spa is feet. If the fence is built along the immediate edg

MariettaO [177]

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

$P = 2 \pi*r$

Where "r" represents the radius of the circle, in this case $r = \frac {5} {\sqrt {2} -1}$

Substituting in the perimeter equation we have:

$P = 2 \pi * \frac {5} {\sqrt {2} -1}$

Rationalizing we have:

$P = \frac {2 \pi * 5 (\sqrt {2} +1)} {(\sqrt {2} -1) * (\sqrt {2} +1)}\\P = \frac {2 \pi*5 \sqrt {2} +2 \pi*5} {2-1}\\P = 10 \pi \sqrt {2} +10 \pi$

Taking out common factor $\pi$ :

$P = (10 \sqrt {2} +10) \pi$

Answer:

$P = (10 \sqrt {2} +10) \pi\ feet$

in the fall semester of 2003, the average graduate management admission test (GMAT) of the students at UTC was 500 with a standa

MAVERICK [17]

Answer:

The 2003 scores have a higher coefficient of variation, so they are more dispersed

Step-by-step explanation:

We have to find the coefficient of variation(CV) for both these tests.

$CV = \frac{\sigma}{\mu}$

In which $\mu$ is the mean and $\sigma$ is the standard deviation.

Whoever has the higher CV has the higher variation, that is, is more dispersed.

2003

$\mu = 500, \sigma = 80$

$CV = \frac{\sigma}{\mu} = \frac{80}{500} = 0.16$

2004

$\mu = 560, \sigma = 84$

$CV = \frac{\sigma}{\mu} = \frac{84}{560} = 0.15$

The 2003 scores have a higher coefficient of variation, so they are more dispersed.
