percent of change  =  (amount of change) / (original amount) x 100

amount of change  =  83 - 56  =  27

original amount = 83

percent of change  =  27 / 83 x 100  =  32.53%  (approximately)

Area = length x width

length = 41 1/5 inches = 41.2 inches

width = 23 3/4 inches = 23.75 inches

Area  =  41.2 x 23.75  =  978.5 square inches

cos^-1(24) does not exist because the value of cos must be between -1 and 1, inclusively.

What is x approaching?

you use the divide sign

$$f=ma$$

$$a= f/m$$

Sure it is, sure

Rise  over Run my friend :)

$$|-5-3|=|-8|$$

now the absolute value of a number is how far it is from 0 on a number line.

SO positive numbers stay positive and negative numbers become positive.

so the answer is  just      8 

(66 - 2^x) / ( 2^x + 3)  = (4 - 2^x) / (2^(x+1) + 6)

The easiest way to solve this is to graph both sides and see if there are any points of intersection

Check if there was anything level with their height, then meausre the thing that is near their height.

You do the / sign. So, if I was doing one tenth, it would look like this: 1/10

It is larger because it is closer to one.

the woodchuck would chuck as much wood as the woodchuck could

-12=f/0.2   multiply both sides by 0.2

(0.2)(-12) = f = -2.4

Y=1/2x+3 does x=3 and y=4

If x = 3  then y = (1/2)(3) + 3  =  3/2 + 3  = ( 1 + 1/2) + 3  = 4 + 1/2  = 4.5

I have put another answer post on the original question.

If you still do not understand let us know.   :)

WE ALWAYS WANT PEOPLE TO ASK WHEN THEY DO NOT UNDERSTAND. :)

Thank you for asking anon :)

I have used the formula 

$$FV = PV*(1+i)^n$$

where FV is furure value

FV = $5000

PV is present value

PV = ?     This is what we need to find

i is the interest rate per compounding period 

i= 4% = 0.04   and this is yearly

n is the number of compounding periods

n =10 because it is 10 years

so

$$\\5000=PV(1+0.04)^{10}\\\\
5000=PV*(1.04)^{10}\\\\
$You need to divide both sides by $1.04^{10} $ to get the PV by itself$\\\\
PV= 5000\div(1.04)^{10}\\\\$$

$${\frac{{\mathtt{5\,000}}}{{{\mathtt{1.04}}}^{{\mathtt{10}}}}} = {\mathtt{3\,377.820\: \!844\: \!128\: \!994\: \!282\: \!6}}$$

you will need to invest $3377.82 

Now let me know if you do not understand and try to explain which bit is giving you problems.   :)

2+(19/3)=(4/3)x+(3/4)x

(6/3)+(19/3)=(16/12)x+(9/12)x

(25/3)=(25/12)x

4=x

The largest cube we can use would be 7

And we can pair this with the integers (1 trough 5 cubed)...."6' is too large!!!

So that's 5 numbers right there

And 6 cubed can be paired with integers (1 through 5 cubed) = 5 numbers

And 5 cubed can be paired with (1 through 4 cubed) = 4 numbers, etc.

So we have....

5 +  [ 5(6)/ 2 ] =   5 + 15  = 20 numbers

We need to see what you do not understand.

Do you know how to copy the other address and post it in here?

That was very nice, saseflower......!!!!
