L = lenght

1/10 L = width

perimeter = L + L + 1/10 L + 1/10L =  2 2/10 L

area = L x 1/10L

2 x area = perimeter

2 x L  x 1/10 L = 2 2/10  L     Divide both sides by L

 2/10 L  = 2 2/10

L = 22/10 x  10/2

L = 220/20  ===== 11   then  W = 11/10

To find the discount, simply multiply the original selling price by the %discount:

ie:  39 x ³³/₁₀₀= $12.87

So, the discount is $12.87.

To find the sale price, simply minus the discount from the original selling price:

ie: 39- 12. 87=  26.13

So, the sale price is $26.13

Since you want equal amounts in each glass, divide the total amount of juice, 577 pints, by the number of glasses, 15.]

ie 577 ÷ 15= 38.4666666666666667.

So you'd have to pour 38.4666666666666667 pints in each glass

Simply multiply by 100 and add the %.

that is, 5.4 x 100= 540%. Just move the decimal place 2 places to the right.

thanks plz answer my other question cphill

7/8 is bigger.

Simply change the numbers to the same form, whether both to decimals or both to fractions. That way you'll easily see which is bigger

 so changing both to decimal gives:

7/8 is 0.875 which is bigger than 0.78

y-45=.91(x-40).....the equation of a line

cos C  = 2.2^2+2.6^2-2.3^2÷2×2.2×2.3

cos C  = -1.7837   =   does not exist

Push the "2nd" button on the calculator.....find the "atan" function

So use BOMDAS (Brackets of Multiplication,  Division, Addition and Subtraction) rule to start.

Therefore you'd work out all task contained in brackets first, ie:

-> (0.120) (0.08206)(296.15) ÷ (0.30263)

(Note- all i did was to rewrite 8.206 x 10 ^-2 as a decimal not in standard form)

Then do all multiplications, ie:

-> 2.91624828 ÷ 0.30263

Then divide:

-> 2.91624828 ÷ 0.30263= 9. 6363

Since you didnt state the number of significant digits required, I'm just going to leave it at 5.

4x ( 4x + 2)^(1/4)  ( x² + 1)²  + (1/3)( 4x + 2)^(-3/4) (x² + 1)³     factor

( 4x + 2)^(-3/4) ( x² + 1)²  [  4x (4x + 2)  + (1/3)( (x² + 1) ]  =

( 4x + 2)^(-3/4) ( x² + 1)²  [ 16x² + 8x + (1/3)x² + (1/3) ]  =

( 4x + 2)^(-3/4) ( x² + 1)² [ (49/3)x² + 8x + (1/3) ]

2^(-3/4) (2x + 1)^(-3/4)  ( x² + 1)² [ (49/3)x² + 8x + (1/3) ]

cosθ = 3/4.....

sinθ  =  √[1 - (3/4)^2 ]  =√[ 1 - 9/16] = √ [7] / 4

sin( pi + θ) =   sin(pi)cosθ  + cos pi sin θ  =  0 +  ( - √ [7] / 4 )  =  - √ [7] / 4

it equals your life. Oh yeah, the answer doesn't exist.. :D

Thanks, Suki......welcome....!!!!

Here your task simply is to get y  by itself.

start by removing any value on the same side of the  equation as y:

ie. 4x - 9y =20 (bring 4x on the other side of the equation by subtracting 4x from both sides)

-> 4x- 4x -9y= 20- 4x which results in:

-> -9y= 20- 4x

Now since we are solving for y and not -9y, we bring the -9 on the other side of the equation by dividing both sides by -9, like:

-> -9y/ -9= (20-4x) / -9

which is:

-> y= (20-4x) / -9

 therefore your answer is

y= (20 - 4x) / -9

Step 1: 798/ 8= 99.75

Step 2: 99.75 * 41 = 4089.75

The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.

If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.

Since the number following the significant digit, 4, is zero we therefore round down the number.

Resulting in:

4000.

Therefore, your answer is 4000

'k' is the number of times the loan/deposit interest is compounded per year      and 't' is the number of years

      ' r' is the DECIMAL interest rate

 Thanks a lot!

3w * (-w)  =

3w * (-1w)  =

3 * -1 *  w * w  =

-3w^2

Ok, so:

-13 / -10= 1.3

Because a negative divided by a negative results in a positive number

4 - 2a < 3a-1       add 1, 2a   to both sides

5 < 5a             divide both sides by 5

1 < a
