One minute is 1/60 of an hour. So 12 minutes would be 12/60 of an hour, or 1/5 of an hour reduced, and or .2 in decimal.

A woman standing on a hill sees a flagpole that she knows is 40 ft tall. the angle of depression to the bottom of the pole is 14

NemiM [27]

Let distance form the pole = x and height of the hill = y ft

now we can set up 2 equayions
tan 18 = (40-y)/x
tan 14 = y/x

from second equation y = sxtan14 so we have:-
tan 18 = ( 40 - x tan 14) / x

x tan 18 = 40 - x tan 14
x(tan 18 + tan 14) = 40

x = 40 / (tan18 + tan 14) = 69.66 feet Answer

Rewrite each expression without using absolute value notation.<br><br> |x-y| if x>y

anyanavicka [17]

The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.

<h3>What is an absolute function?</h3>

The absolute function is also known as the mode function. The value of the absolute function is always positive.

The absolute function is given as

f(x) = | x |

If the value inside the mode operator is greater than zero, then simply the mode operator is eliminated.

The notation of the absolute function is given below.

|x - y| If x>y

Then the absolute function is given as,

|x - y| = x - y

The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.

More about the absolute function link is given below.

The table shows the number of minutes Garrett practiced his trombone each week in one month. Week Number of Minutes Practiced 1

vredina [299]

Answer:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week 1 2 3 4

Minutes 190 163 327 205

For this case we can find the mean with the following formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If

frutty [35]

For this case we have the following equation:
$w = 0.9* \sqrt{E}$
Where,
w: The weight of a spring in pounds
E: the energy stored by the spring in joules.
Substituting values we have:
$w = 0.9* \sqrt{12}$
Making the corresponding calculation:
$w=3.12$
Answer:
the approximate weight of the spring in pounds is:
$w=3.12$
