Answer:

A) 23 · 32

Step-by-step explanation:

The easiest way to decompose (or factor) a number is to start by trying to divide it by 2 if the number is even, or by 3 if the number is odd. If this division gives a whole number, continue dividing by 2 or 3, until you obtain a prime number:

72/2 = 36

36/2 = 18

18/2 = 9

9/3 = 3

The multiple of all the bold numbers is the prime factorization of 72: 2 · 2 · 2 · 3 · 3. This is more commonly expressed as powers of 2 and 3: 23 · 32. The last answer choice is also equal to 72, but is not a prime factorization of 72 because it contains 8, which is not a prime number.

A circle with radius 9 has a sector with a central angle of 120°.
Vitek1552 [10]

120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.

A circle with radius 9 has area 9^2 π = 81π.

So the sector has area 81π/3.

Put another way: The area <em>A</em> of a circular sector and its central angle <em>θ</em> (in degrees) occur in the same ratio as the area of the entire circle with radius <em>r</em> according to

<em>A</em> / <em>θ </em>º = (π <em>r </em>^2) / 360º

==>  <em>A</em> = π/360 <em>θ r</em> ^2

In this case, <em>r</em> = 9 and <em>θ</em> = 120º, so

<em>A</em> = π/360 * 120 * 81 = 81π/3

Step-by-step explanation:

The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Reason -

Option A is incorrect because the statistics can not be incorrect.

Option B is incorrect because they are not talking about the city.

Option C is correct because Urban rail reduces congestion.

Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.

Option E is incorrect because they are providing an explanation for why the commuters data given by opposers is not relevant. The opposers talked about commuters.
