Emma cut a square hole out of a block of wood in wood shop. if the block was cube-shaped with side lengths of 12 inches, and the hole had side lengths of 3 inches, how much wood was left after the hole was cut out?

Hello Guest!

\((12^2-3^2)\ in^2\cdot 12in=\color{blue}1620\ in^3\)

\( 1620\ in^3\ \text{wood was left after the hole was cut out.} \)

Why, when I visit this forum, does it often seem like I’m back in junior high school? 

It’s not the junior high students causing this.

We heed to  use z scores here

The formula  is    :

   score - mean

  ___________  =    z score

   std deviation

a.    This one is easy.....to be in the top 50%......since the mean is 18.....then you need a scure greater than or equal to 18 to be in the top 50%

b.    We need to  use a z score table  ( here) : http://www.z-table.com/  and find the z score  closest to .10......this is the z score -1.28

So  we can solve this

x  -  18

_______ =   -1.28                 multiply both sides by  6

   6

x - 18  = -7.68     add  18 to both sides

x =  10.32 =  score we need to be in the 10th percentile

c.  To be in the 99th percentile......we can find the z score closest to  .99.....using the table we find that this is about 2.33

So  we can solve this

x - 18

_____  =   2.33       nultiply both sides by 6

    6

x  -18  = 13.98   add 18 to both sides

x = 31.98  =  the 99th percentile score

d.  To be in the top 25% of the students  we  need  to  find the z score closest  to  .75.....using the table we have the z score of about  .68

So

x - 18

______  =   .68             multiply both sides  by 6

x - 18 =  4.08     add 18 to both sides

x = 22.08  = we need at least this score to be in the top 25%

thank you for your help

What does the high and mighty, MicroDick brain, pansyass, f u c k f a c e want me to cry about?

You like sticking your MicroDick into everything on here.

i cared that you said nobody cares

My first date with Donna was a disaster. I decided to take her to a small Italian restaurant. That my friends told me had reasonable prices. I looked over the menu and realized I could not pronounce the names of the dishes. Such as “veal piccata” and “fettuccini Alfredo.” Then I noticed a burning smell. The candle on the table was starting to blacken. And scorch the back of my menu. Trying to be casual, I quickly poured half my glass of water onto the menu. When the waiter returned to our table, He asked me if I wanted to order some wine. I ordered a bottle of Blue Nun. The only wine that I had heard of and could pronounce. The waiter brought the wine, poured a small amount into my glass, and waited. I said, “You don’t have to stand there.We can pour the wine ourselves.” After the waiter put down the wine bottle and left. Donna told me I was supposed to taste the wine. Feeling like a complete fool. I managed to get through dinner. However, for weeks afterward, I felt like jumping out of a tenth-story window.

Here is my guess:     from 2 to 3.6   = 1.6      from   2 to 7 = 5      1.6/5          or     8/25

In each question , you are given all but one of the variables......plug in the values and solve for the unknown variable....

Example: 1      M1 = 447 kg      M2 =285 kg    r = 27 m     and G is given above....plug in all of the values and solve for  F of gravity.

I do not kow why my posts were flagged....here is the image of the equation

T =Tony's amount

L = 9+T

A = 3T       added together = $ 84

T +    9+T    +   3T = 84      Solve for T, the amount Tony has      then Lisa has  9+T     and       Alonzo has   3T

Here's my attempt for the first one  :

i. Mahowny rolls a 6-sided die five times, and the product of his rolls is 1200. How many different sequences of rolls could there have been? (The order of the rolls matters.)

1200  factors  as      2^4 * 3  * 5^2 =   2 * 2 * 2 * 2 * 3 * 5 * 5  =  4 * 4 * 3 * 5 * 5

So....the number of different identifiable roll sequenes  =

        5!                        120      

    _______  =            ____    =     30

     2!  * 2!                      4

Power = Force * velocity

force parallel to movement would be   F cos 60

Power = F cos 60 * 4 m/s

160 W  = F cos 60 * 4 m/s  

160   kg-m²/s³   = ( F cos 60) kg-m/s²      * 4 m/s     Solve for F  (which will be in Newtons      A newton is  kg-m/s²⁾

Then use the "F" found above:

Work = F * d   =    F  *  2 m   

All of the questions can be answered with the following equation....you are given all of the variables except one.....plug in the given numbers and solve for the unknown:

There are 3 radii:  r=10,  r=7, r=3  

All of these equations are solved using the following equation: (from the internet)

If these  two  measures  were  the shortest sides of an acute triangle.....then  the third side  would  have to be less than √[33^2  +  65^2 ]  ≈  72.89

But  if  the longest side of  the  triangle was 65.....the other side would have to be greater than √[65^2 - 33^2]  = 56

Are we really supposed to be helping you on a test??

Let  angle  A  =  x

Let angle B = 3x

Let angle C = 3x - 23

And the sum of these   =180

So

x  +  3x  +  ( 3x - 23)    =180      simplify

7x  -  23  =  180            add 23 to both sides

7x  =  203                divide both sides by 7

x  = 29°  = angle A

3(29) = 87°  = angle B

3(29)  - 23  = 64° =  angle C

If independent.....then......

P ( A / B )   =  P (A) 

P (A / B ) =   P (A ∩ B) / P(B)   =   .06  /  .3    =   (6/100) / (3/10) = (6/100) * ( 10/3)  = 60 / 300  = 1/ 5  = .2 = P(A)

So......you are correct !!!

Two sides of an acute triangle measure 33 units and 65 units. Which is a possible length for the third side? 

a = 33        b = 65       

Side  'c'  should be longer then 56 but shorter then 72.89718787
