ok ill try XD;

2003 --> 2013 = 10 years

total change is 9372-7930 = 1442

1442/10 = change per year (if linear) = 144.2

if you take one year to be one value on the x line

and you take 1 (from the change value) to be on value in the y line

then rise/run = gradient

rise = 144.2

run = 1

therefore gradient = 144.2

equation of a line = mx + c = y

where m=gradient

x=x intercept

c=y intercept

so - y = 144.2x + 0

(as you said that the first point is 2003 - and therefore lies on the y axis)

I may be wrong

1029 - 56 = 976

976 + 5 = 981

anything from 976-->981

for a solution to be neutralised you need the the molar values to be equal

so if your equation was - A + 2B = ...

you would need twice the Bs to neutralise the As

im assuming that mL = milliliters?

for any equation of neutralisation;

concentration (of A) times volume (of A) = concentration (of B) times volume (of B)

and you need to factor in the ratio

just plug in the concentration values (im assuming thats what molarity is) and the volumes (both sets need to be in the same units) and solve

eg.

HCl + NaOH === NaCl + H2O

if i have 20cm3 of NaOH at 0.5mol/dm3 and it neutralises 15cm3 of HCl - what is the concentration of HCl?

ratio of HCl to NaOH = 1:1

convert units - 20/1000 (cm3 to dm3)

therefore;

(20/1000) times 0.5 = (15/1000) times x

where x = concentration

((20/1000) times 0.5)/(15/1000) = x = 0.6recurring mol/dm3

The wall is 800 sq. ft.....thus, you need 2 gallons.......unless you're going to paint both sides.....then, you need 4 gallons

The first term:

(1/x^-1)^-1      = (  1/(1/x)  )^-1     1/ (1/x) =  x   so this simplifies to  x^-1   which equals   1/x

The second term:

(x^-1 + y^-1)  =   ( 1/x + 1/y)

Now Multiply them together

1/x (1/x + 1/y) =  1/ (x^2) + 1/(xy)

5 is right

Hello.

(-5/9)^2  =  25/81

8.99% of 20,000

this equals     20,000 x .0899 = 1798

Very nice, Melody and Guest.....!!!!!

8.25   =   8  25/100 = 8 1/4

Wavelength=c/v, where c is the speed of light, v is the frequency

v=c/w=299,792,458/6.35 X 10^9

v=4.72 X 10^-2 Hertz.

However, you don't state the units of the wavelength, i.e., is it in meters, centimeters, kilometers.....etc. I assumed meters in my calculation.

1  875/1000       Simplified   1 7/8

4 is the answe

Since the interest rate is compounded monthly and the payments are made annually, we must adjust the interest rate from monthly compound into annual compound. Therefore, 7.2%=7.44%.

The annual payments required each year to have an investment of 20,000R at the end of four years is calculated to be 4,475.16R.

To find the answer multiply .16(which is 16% ) with 150

150×.16=24

Neither is warm enough to actually cook the pie.

Old enough to know better.....but still too young to care.

Not sure what you are asking here, but:

This is the Quadratic Equation used for finding the value(s) of 'x' when the form of the equation involving 'x' is

ax^2 + bx + c = 0

First one:

7(4a+2) = 35    Divide both sides by 7                                                              

4a+2=5             Subtract 2 from both sides                                                           

4a=3                  divide both sides by 4

a=3/4

Second one:   8-(6m/5)=2     subtract 8 from both sides

-6m/5 = -6                              multiply both sides by -5/6

m=-6(-5/6) = 5

Sorry, the format of my first answer got garbled!!

Its 3:1

First one:                                                                                    Second one:   8-(6m/5)=2     subtract 8 from both sides

7(4a+2) = 35    Divide both sides by 7                                                                 -6m/5= -6       multiply both sides by -5/6

4a+2=5             Subtract 2 from both sides                                                             m= -6(-5/6)=5

4a=3                  divide both sides by 4

a=3/4
