A,B,C,D,E,F,G,H,I,J,K are the points of intersections of the dotted lines and the wire.....plz check the attachment Now the total length of the wire (L wire) can be calculated as follows,L wire = length of straight line AB + circumference of semicircle BCD + length of straight line DE + circumference of semicircle EFG + length of straight line GH + circumference of semicircle HIJ + length of straight line JK= (4.1 cm) + (pi* 0.9) + (5.9 cm) +...http://www.enotes.com/homework-help/can-you-help-me-work-out-length-wire-used-make-479572Sat, 23 May 2015 07:56:31 PSTOk from there we move the numbers over to the opposite side by adding 11...

Ok from there we move the numbers over to the opposite side by adding 11 to each side -1=-11+4x +11 +11 Now we can solve! 10=4x Dovide each side by 4 to get the variable by itself 10/4= 4x/4=x x=2.5http://www.enotes.com/homework-help/12-2x-1-1-2x-479775Sat, 23 May 2015 03:23:30 PSTHere is your equation... 12-(2x+1)=1+2x Now, let's start with and easy...

Here is your equation... 12-(2x+1)=1+2x Now, let's start with and easy step- subtracting 12 from both sides 12-(2x+1)=1+2x -12 -12 Here is what we have now -(2x+1)=-11+2x Lets put the 'invisible' one in front of the positive side to make things clearer -1(2x+1)=-11+2x So now we can use distribution. We need to multiply both the 2x and the +1 by the -1. Now we have... -2x-1=-11+2x Now we need to get the like terms to one side.

Given , 28 = 6x - 4y As all the coefficients are even numbers ,so they are divisible by 2 . By dividing with 2 we get 14 =3x-2y => Again divide the present equation by 2 so we get 7=(3/2) x-y => 7+y= (3/2) x => now we can rewrite the above equation as y= (3/2) x -7 simple :)http://www.enotes.com/homework-help/how-do-rewrite-that-y-function-x-28-6x-4y-479600Fri, 22 May 2015 16:24:48 PSTplz check the full solution of ur question in the attachments ..........

The demand equation is a linear equation and it defines the algebraic representation of quantity and price of product. The form of equation of linear function is the following, such that: `P(x) = a*x + b` The price point elasticity of demand can be evaluated using derivative of demand function Q, with respect to price P, such that: Point Price Elasticity of Demand = `(Delta Q)/(Delta P)` Given `Q(x) = 600 - 3P(x) + 0.04I - 2P(z)` and...http://www.enotes.com/homework-help/please-help-suppose-we-have-following-hypothetical-479797Thu, 21 May 2015 18:13:41 PSTGiven 12-(2x+1)=1+2xlet (2x+1) = (1+2x)=yso 12-y=y=> 12=2y=>...

Since 3 men and 3 women needs to be part of delegation, and since selection is from 5 men and 3 women....it implies that all the women would always be part of the delegation. Since either youngest woman or youngest man can be in delegation, and since all women are in delegation; the youngest man will never be a part of the delegation. That leaves the selection of 3 men from a set of 4 men and this can be done in 4 ways. So, there are only 4...http://www.enotes.com/homework-help/dear-educator-please-help-me-find-solution-this-479838Thu, 21 May 2015 15:24:44 PSTdear Educator please help me find solution for this math problem ; here...
