A.   Ellipse

A. cylinder

Let the side of the square  = x

So.....the height of the  box will be x

And the base  area is   (12 -2x) (1- 2x)

So....the area is

Base area * height  =

(12 - 2x) (10 - 2x) *x   ⇒     "B"

The max area will be a circle

To find the radius....we have that...

Circumference   = 2pi * radius

40  = 2p  * radius        [ divide  both sids  by  2 pi]

40 / (2 pi)   = radius    =   20 /pi

And the area of the  circle is

pi * (radius)^2  =

pi * ( 20/pi)^2  =

400/pi    m^2  ≈   127.32 m^2

Next smaller text size  =

(1.772) / ( 1.21) =  1.464    ( rounded to  the  nearest thousandth )

The next larger size  =  (1.333) (1.777)  = 2.368741 ≈  2.369   (rounded to  3 decimal places )

1.

[ Sarah's point total -  17 ]

____________________     =    2.8       multiply  both sides by 4

           4

Sarah's point total  -   17 =     11.2        add 17 to both sides

Sarah's point total   =    28.2

2.  A z-score of  2.8 means that she scored more points than about  99.74%  of  the participants.....this would be  considered very unusual

For a certain font, the scale factor is 1.333 and one of the scale sizes is 1.777.
 

What is the next larger scale size?  

Enter your answer as a decimal in the box. Round only your final answer to the thousandth.

First one looks good

Second.....

[ 6 -  8 ]/  3.2  =   -2 / 3.2  =   -0.625    ......Correct   !!!!!

What is the slope of this line?

It is possible that they understood how to solve it and finished the problem for you.

She's trying to teach you part of what we do here is point people in the right direction.

Thank you @emraldwonder. However, you only did half of the question. It then asks you how much 3 boxes are. So, you multiply 1,440 by 3 to get 4,320. Thanks for the help!

P.S. I like your new profile picture!!!

Triangle ABC has vertices at A(5,8), B(3,-2), and C(6,1). The point D with coordinates (m,n) is chosen inside the triangle so that the three small triangles ABD, ACD and BCD all have equal areas. What is the value of 10m+n?

Well, the main reason is the sub-moron English dialect they use is difficult to translate.

English sub-moron dialects range from low-level imbecile to high-level idiot. EmeraldWonder usually writes in the mid-range of idiot, which is why I can understand her most of the time.  HiylinLink writes in low to mid-level imbecile, while LovinLife and the others in that collective are closer to low-level imbecile.

Interestingly, they appear to understand each other. I wish I had more time to study this social structure and its related languages. It reminds me of the semester when I studied wild turkeys. Turkeys are incredibly dumb birds –well dumber than chickens, yet they do communicate information to each other.

The formal definition for summations defined recursively is

\(\sum \limits_{i=a}^{b}g(i)=0 \qquad | \text {for b < a}\\ \sum \limits_{i=a}^{b}g(i)=g(b)+\sum\limits _{i=a}^{b-1}g(i) \qquad| \text {for b > a }\\\)

Note that the zero (0) result is true for all summations where the lower limit is larger than the upper limit.

So, Mr. BB, wouldn’t it be rather pointless to present a finite series only to define it as zero (0)?  I suppose there may be reasons for this, but this series isn’t one of them.

Ginger, I see that you are online. Why haven’t you responded to these rants?

It is 999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

was  there any question?

:D

The centroid of a triangle will divide the  triangle into  3  equal  areas

The coordinates of the  centroid are  given  by

;

 (  [sum of the  x coordinates of  the  vertex points ] / 3 , [ sum of the  y coordinates of the vertex points ] / 3 ) =

( [5 + 3 + 6 ]  /  3  , [ 8 + -2 + 1 ] / 3  )  =  (  14/3, 7/3)

So

10m + n   =

10 ( 14/3) + (7/3) =   140/3  +  7/3   = 147/3   =   49
