What is the factorization for 140?
The process: 70x2 35x2 5x7 The answer is 2x2x7.
How many tomatoes do you need for 70 people?
140 tomatos 70x2=140
What is the greatest common factor of 140 and 70?
Since 70 is a factor of 140, it is automatically the GCF.
How do you factor 20x cubed minus 70x squared plus 60x?
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
A box is made from a rectangular piece of metal whit length 20 inches and width 15 inches. The box has no top. What are the limitations on the size of x?
x<7.5 To find the maximum volume of the box: A square of side x inches is cut from each corner of the sheet and the remaining flaps folded up to make the topless box. The box therefore has a height of x", length of 20 - 2x and width of 15 - 2x. Volume is thus x * (20 - 2x) * (15 - 2x) ie 300x - 70x2 + 4x3 The volume is greatest when this has a maximum value: f(x) = 300 - 140x + 12x2 (or 12x2 - 140x + 300) Quadratic formula gives a value within the limit of x = 2.83 representing a box 14.34 * 9.34 * 2.83 ie 379.04 cu in.
How do you get an estimate for skirting a trailer?
The panels are typically 16" wide, and 12 feet long. Measure the height of your trailer from the ground to about 6" above the bottom of the frame (for the top piece that holds it in place). You can use this to calculate how many pieces you will need. For example, if your trailer is 14 x 70', that means you need panels to cover 14 x 2 + 70x2 = 168 feet WIDE, that is, 2016 inches. So, 2016 divided by 16 inches = 126 panels. So, you would need 126 panels that are 16" wide. Then, take into account the length. If you want a really accurate estimate, you should measure the height of your trailer every 16" all the way around your trailer (126 times), and use this to tell how many feet (length) you will need. You will also need 168 feet of the bottom rail which attaches to the ground and holds it in place, also 168 feet of the back top rail and 168 feet of the front top rail (which holds it in place at the top). You should also allow a little for "waste", i.e., little pieces left over that are too small to be used. Hope this helps.
