The diagonal of a square is 14, find the area of the Sqaure

Let the side be x

\(\mbox{The area will be }x^2\;\;units^2\\ x^2+x^2=14^2\\ 2x^2=196\\ x^2=98\\ \mbox{So area is 98 }\;u^2 \)

1) Your Charity should receive a total amount of $713,518.29 each and every year for the first 25 years.

2) It naturally follows that your payments for the following 25 years =$713,518.29 x 2=$1,427,036.58 each and every year.

3) And for the last 25 years, your Charity should receive=$713,518.29 x 4=$2,854,073.16 each and every year.

4) I have verified these calculations on my computer software, and they are accurate to the cent.

If you have any questions, just let us know on this Forum, and will be glad to answer them.

The three men working together can finish the job in the reciprocal of:

1/12 + 1/8 + 1/6=3/8 or in 8/3 =2 2/3 hours. Therefore, when Adam leaves after 2 hours, 2 / (2 2/3) or 75% of the work has already been finished. The remaining 1/4 of the job left, or 2 2/3 / 4=40 minutes, while all 3 men were working together. However, this 40 minutes, or 1/4 of the job remaining can be finished by the two remaining men in: 1/12 + 1/8 =5/24 or (24/5) x 1/4=1.2 hours, or 72 minutes. Therefore, before Mike leaves, the job will have been finished.

What is the standard deviation?

There is a formula for this (2 actually) but

standard deviation is a measure of how far a score deviates from the average.

ex

Say all your class members heights were recorded and the mean and standard deviation was calculated.

If I was told you were 2 standard deviations below the mean (and I was told nothing else) then I would know that you were quite short.

Where as if you were 3 standard deviations above the mean I would know that you were really tall !

Thank You

x + 5 > 2x + 1 and -4x < -8

x + 5 > 2x + 1              -4x<-8

    5  > x+1                      x>2

    4  > x                          2<x

    x <  4

 Put them together and you get

2 < x < 4

Even if your calculator can't handle large numbers such as this number, you can find the answer doing the following: 20^1440. You take the log of 20, which is:1.3010299956639811952137388947245. Then you multiply this number by 1440=1,873.4831937561329211077840084033. You subtract 1,873, which the power or the exponent of 10. Then you raise 10 to power of the remaining fraction, thus:

10^.4831937561329211077840084033=3.0422419887462074119071134929958. These are the initial digits of your number X 10^1,873

im too lazy to solve it since i have to do my homework :P

but for the first 2 hours all of them combine efforts so 

(1/12+1/6+1/8)*2 that much work done

then you use same logic and stuff for when the kids leave and stuff

glhf

if it equaled zero, then

it would factor out to be

(x-3)² 

 So x-3 would equal zero

x=3????

yeah its and expression and im assuming it equaled zero

please post more accurate questions please

The question isnt worded properly, is x an angle? Side? w*f

U cross off 

the you add 32 and46 = 78

then 78 divided by 2 is 39

The answer 39

1.5

lol

since 3*1/2=3/2

3/2=1.5

You in like 3rd grade or something?

Wrong, as long as there is new science, there will always be new math

lol

This number is TOO BIG for this calculator. It cannot handle large number like this one. However, I have a calculator that CAN handle numbers like this:So, 20^1440 = 3.042241988746207411907113492996 x 10^1873

We want to know when

60 + 5x  = x^2   + 46       subtract 60, 5x from both sides

0  = x^2 -5x -14            factor

0= ( x - 7) ( x + 2)   setting both factors to 0

x - 7  =  0                        or                   x + 2  = 0

add 7 to both sides                              subtract 2 from both sides

x = 7  weeks                    or                 x  = - 2   weeks

Only the first answer makes sense.........in 7 weeks they will have the same amount of money

Well that depends on the kind of answer you want exact or an estimate.

Estimate (just punch it into a calculator):

 2.6457513110645906

Exact (cannot be simplified):

\(\sqrt{7}\)

Nope. Simply put, we cannot fathom the amount of mathematical... what's the word... I'll just say math. It would be impossible to stop advancing in math, especially to stop working on it. Mathematical applications are all over, everywhere you look, there may even be some which humanity has not discovered yet. I had a debate with my Calculus teacher about this, he told me something that kind of blew my mind, "Just as math can go to infinity, so can mankind."

A ramp design for people in wheelchairs

1. as part of the works of social inclusion and accessibility, it is required to design a ramp for people in a wheelchair. In the community where you live, you know that you are studying physics, so come to you to carry out your design, which must complywith the following requirements:

That approach to the ramp area is 120 cm wide.

That the slope (slope) is not greater than 6%.

That length is not greater than 600 cm. In case of exceeding this length, including breaks of 150 cm in length.

Uniform and non-skid floor.

A sign prohibiting the obstruction of the ramp.

Place the international symbol of access for people with disabilities.

Data from the space where you want to build is shown in following table. Performs the calculations required to complete and publish the development of these. It takesinto account that the angle should be handled in degrees.

Ben brought a digital camera for $90. The tax rate is 6%. Which proportion can be used to find the amount of tax Ben will pay? Please help me!!!

I suppose the proportion is      6/100

Tax = 6/100  *  90  = $5.40

You add all the data values together, then divide by the number of data values

Simplify the following:
(n^2 p^2)/(p^4 n^5)

Combine powers. (n^2 p^2)/(p^4 n^5)=n^(2-5) p^(2-4):
n^2-5 p^2-4

2-5=-3:
n^-3 p^(2-4)

2-4=-2:
Answer: |  (p^-2)/(n^3)

Thank you! :)

10                      10

----          =       ------

3^2                     9

But ...........

(10 / 3)^2  = (10/3) (10/3)  =  100/9

1/6

-----      =    (1/6) * ( 5/3)   =  5/18

3/5
