twelve -------------------- The original rectangle is 12 feet in length and 5 feet in width. The length (12) is 7 feet greater than the width (5 feet). Were the length decreased by 3 (12 - 3 = 9) and the width increased by 2 (5 + 2 = 7), the perimeter would be 32 feet (9 + 7 + 9 + 7 = 32).
Not enough information: Both the change in absolute terms, and the percentage change, would also depend on the original size of the cube.
rust is iron oxide. so what's happening at the atomic level is oxygen is bonding to the iron. The iron stays with oxygen attached, the oxygen is the increased weight.
Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
Original density = M/VNew density = (KM)/(KV) = (K/K) (M/V) = original density.If the mass and volume both increase by the same factor, the density is unchanged.It only means that you have a larger piece of the same substance.
There were the original British Colonies.
Since the original atmosphere, the gases which have decreased are water vapour and carbon dioxide and the gases which have increased are nitrogen, oxygen
10d+8=12d the origian square is 4x4
The perimeter of a rectangle is just the sum of the lengths of its sides, so taking half of each of the sides would make the total half of its original value also.
The perimeter of a rectangle is given by (2L plus 2W). If you double either the width or length dimension, then it is four times the original dimension, such as (4L plus 2W) or (2L plus 4W).
29 unitsSince each side is increased by two units, and there are seven sides, then each side will be affected.The total effect will be (+2 units) x (7 sides)=+14units for the 7 sidesSince the original perimeter is 15, then15+14=29The perimeter is 29 units.
You need to write two equations with two variables each, for the two facts. Remembering that the perimeter is the sum of the lengths of all the sides:Write an equation for the perimeter of the original rectangle:perimeter = 2(length + width)26 = 2(l+w) (equation 1)Write an equation for the area of the increased rectangle:A = length x widthA = (l+4)(w+3) (equation 2)Solve the two equations simultaneously; and you'll get the width and length of the original rectangle.
The final result is 10.4% more than the original number.
9 feet was the original side lengths
The perimeter is also twice as large.
% change is the % of increase or % of decrease. % change = (difference of the two values / the original value) x 100% =[(original value - new value)/original value] x 100% % increase -if the value increased % decrease -if the value decreased
the medial triangle is 1/2 the perimeter of the original triangle and has 1/4 the area of the original triangle
