Sorry, I have to correct you drwls the slope of 5x + 4y = 4 is -5/4 the slope of 4x + 5y = 8 is -4/5
It's easier to just say 18.6% = 0.186 and so 18.6% of 1,300,000 is simply: 0.186*1,300,000 = 241,800 or, doing it the way you were doing above: 100% = 1,300,0000 18.6% = x x = (1,300,000*18.6%)/100% which gives the same answer. Hope that helps.
Well the area will be the sum of the area of a rectangle and either 1 or 2 triangles depending on what way you draw it. The area of the rectangle will be height*shorter length = 4*5 = 20 The area of the triangle will be (1/2)*base*height base of triangle
Area = Length*Width Information you are given: Area = 105cm^2 and Length = width + 8 therefore: 105 = (width + 8)*width 105 = width^2 + 8*width 105 = w^2 + 8w rearranging we get a quadratic: w^2 + 8w - 105 = 0 w^2 - 7w +15w - 105 = 0 w(w - 7) + 15(w - 7) =
Well it was never used as a fuel for transportation as it is extremely volatile. It's flash point is at 54 degrees F/ 12.2 degrees C. [The flash point of a flammable liquid is the lowest temperature at which it can form an ignitable mixture in air]
You can treat greater than and less than signs kind of like equals signs by you can multiply both sides by a number and not change the result or add the same thing to both sides and not change the result. The only thing you have to be careful about is when
The first one is simpler if you do it this way: Multiply both sides by [sin(x)]^2 then: 1+1/tan^2x=1/sin^2x becomes sin^2x + sin^2x/tan^2x = 1 since tan^2x = sin^2x/cos^2x the equation becomes: sin^2x + sin^2x/(sin^2x/cos^2x) = 1 sin^2x +
Almost, the factors are 1,3,9 and 27 itself. Every number is a factor if itself which can be shown by 1 being a factor of everything. Ok, Hope that helps!
Well a picture frame has 4 sides so you need to add the length of all of them. In other words: 2 lengths + 2 widths the answer is: 4 + 4 + 7 + 7 = 22ft You are being asked, in effect, to calculate the perimeter of the photo frame. Ok, Hope that helps!
1) Firstly we need to find the slope of the line the two points are on by using the equation m = (y2-y1)/(x2-x1) m = (5 - 0)/(0 - [-8]) = 5/(0 + 8) m = 5/8 Then use y-y1=m(x-x1) to find the equation of the line. y - 0 = (5/8)*(x - [-8]) y = 5/8x + 5 So
Okay, first we need to get the slope of the line connecting the two given points by using: Slope (m) = (y2 - y1)/(x2 - x1) Therefore: m = (6 - 4)/(9 - 3) m = 2/6 = 1/3 So the slope of the line joining (3,4) and (9,6) is 1/3. To find the equation of the
Well. If you missed 12 questions you got (60 - 12) correct. I.e. 48 questions were correct. So, the fraction of questions answered corectly is: (Number of Correct Questions)/(Total Number of Questions) so that is: 48/60 which can be simplified as 12
Okay, let's see. Well, in this type of question: Fraction of Ribbons = Specific type of Ribbon/Total Ribbons or more generally: Fraction = Part/Whole [or maybe the word 'Total' instead of 'Whole' ] So, you could say, for the above problem that the 'Part' =
Well, If the Slope (M) = -9 and the point is (4,8). The Equation of the line is: y - y1 = m(x - x1) So it becomes: y - 8 = -9(x-4) y - 8 = -9x + 36 y = -9x + 36 + 8 y = -9x + 44 is the equation of the line [written in the form y = mx + c]. Ok, hope that
I don't know a site but I have a suggestion for your adjective. You could use the word 'stubborn'. Hope that helps!
