How does proportional change in the dimensions affect the perimeter of a figure?
If you are asking how the perimeter of an object changes if the whole object is proportionally changed: The perimeter changes by the same factor as the change in proportion of the whole object. For example: given a square that is 2 units by 2 units, changed by a factor of four, the new size would be 8 units by 8 units. The original perimeter was 2+2+2+2=8. The new perimeter is 8+8+8+8=32. So, multiplying the original perimeter, 8, by the factor of proportional change, 4, we get 8x4=32. For any object, multiply the original perimeter by the factor of proportional change to arrive at the new perimeter.
How does the perimeter change when the dimensions are changed by a scale factor of 3?
The perimeter, being a linear measure, also changes by a factor of 3.
How does the perimeter of a figure change if the dimensions are changed from yards o feet?
The absolute value of the perimeter doesn't change, only the unit value which increases by a factor of 3.
What happens to surface area when dimensions are changed by a scale factor?
The area changes by the square of the same factor.
Which change will triple the lateral surface area of a cone?
Any area is proportional to the square of its linear dimensions. So, in order to triple the surface area of a cone, you would have to multiply its radius and height each by sqrt(3) = 1.732 (rounded). It could be done by increasing only the radius, or only the height, but then the proper factor would depend on the other dimension that isn't being changed.

When the sides of a polygon are tripled in length the perimeter increases by a factor of and the area increases by a factor of?
Perimeter is proportional to the linear dimensions, so it increases by 3x .Area is proportional to (linear dimensions)2, so it increases by 9x .

The area changes by the square of the same factor.
If the dimensions of a figure are increased by a factor of 7 By what factor does the volume change?
if all 3 dimensions increase b factor of 7 then volume changes by 7 cubed or a factor of 343
What does it mean to say momentum is directly proportional to mass and velocity?
Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.
What happens to the current if the voltage is reduced by a factor of 3 and the resistance is constant?
Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)
