Answer:

82050 people/mi^2

Step-by-step explanation:

The population of the US is 328.2 million people and the area of the US is 4000 mi^2 as given. The population density is found by (population)/(area), so we input our values in:

Population density = 328, 200, 000/4000 = 82050 people/mi^2

I hope this helps! :)

Answer:

D) 54 cm

Step-by-step explanation:

We can use the Centroid Theorem to solve this problem, which states that the centroid of a triangle is $\frac{2}{3}$ of the distance from each of the triangle's vertices to the midpoint of the opposite side.

Therefore, $R$ is $\frac{2}{3}$ of the distance from $U$ to $V$ , since the latter is the midpoint of the side opposite to $U$ . We know this because $R$ belongs to $UV$ , so $R$ must be $QS$ 's midpoint due to the fact that by definition, the centroid of a triangle is the intersection of a triangle's three medians (segments which connect a vertex of a triangle to the midpoint of the side opposite to it).

We can then write the following equation:

$VR=\frac{1}{3} UV$

Substituting $VR = 18$ into the equation gives us:

$18=\frac{1}{3} UV$

Solving for $UV$ , we get:

$18=\frac{1}{3} UV$

$3 *18=3*\frac{1}{3}UV$ (Multiply both sides of the equation by $3$ to get rid of $UV$ 's coefficient)

$54=UV$ (Simplify)

$UV=54$ (Symmetric Property of Equality)

Therefore, the answer is D. Hope this helps!

So he bought 2 pounds of greens apples.

8-2= 6. He bought 6 pounds of red apples.

The radius of a circular plate is 12 centimeters. What is the area, in square centimeters, of this plate? Write your Anwer using

lesya [120]

Answer:

The area of circular plate is <u>144π square centimeters</u>.

Step-by-step explanation :

<h3><u>Solution</u> :</h3>

Here, we have given that the radius of circular plate is 12 centimeters.

So, finding the area of circular plate by substituting the values in the formula :

$\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12)}^{2}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12 \times 12)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(144)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi \times 144}}$

$\longrightarrow{\sf{Area_{(Circle)} = 144\pi}}$

$\star{\underline{\boxed{\frak{\purple{Area_{(Circle)} = 144\pi\: {cm}^{2}}}}}}$

Hence, the area of circular plate is 144π square centimeters.
