Answer:

9465 people/square mile.

Step-by-step explanation:

If there are  646,449 people in 68.3 square miles for the district of columbia, the unit rate in terms of people per square mile for the District of Columbia will be expressed as shown;

646,449 people = 68.3 square miles

x people = 1 square mile

Cross multiply

646,449 people *  1 square mile = 68.3 square miles * x people

x = 646,449 people *  1 square mile/68.3 square miles

x = 646,449/68.3 square miles

x =  9464.8463 square miles

x ≈ 9465 people/square mile.

<em>Hence the unit rate in terms of people per square mile for the District of Columbia is approximately 9465 people.</em>

Rudik [331]

Answer:

<u>i think</u> it is 40%

she made 2/5 shots so

2/5*2=4/10

i times it by 2 because its out of 100

Answer:

  (c)  27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20

Step-by-step explanation:

As with many multiple-choice questions, you only need to look at something that will discriminate the correct answer from the wrong one.

The highest-degree product term is the product of the highest-degree terms in the factors:

  (3x^5)(9x^6) = 27x^11

This matches choice C only.

_____

In case you're interested in actually performing the rest of the multiplication, the distributive property applies.

  (1 +3x^5)(17x^2 +9x^6 -20)

  = 1(17x^2 +9x^6 -20) +3x^5(17x^2 +9x^6 -20)

  = 17x^2 +9x^6 -20 +51x^7 +27x^11 -60x^5

Writing these terms in order of decreasing exponents gives ...

  = 27x^11 +51x^7 +9x^6 -60x^5 +17x^2 -20
