Debbie is N years old. Edna is 3 years older than Debbie and Shawn is twice as old as Debbie. The expression n+n+3+2n gives the

34kurt

N + n + 3 + 2n = (sum of age)

First change the problem and add 1 in front of the variables (n)

1n + 1n + 3 + 2n = (sum of age)

Next add the like terms which are 1n, 1n, and 2n

1n + 1n = 2n
2n + 2n = 4n

Now 3 is left by itself add it to the problem

4n + 3

SIMPLIFIED EXPRESSION IS 4n + 3

Mr. Sánchez owns a square field. The side lengths are 0.9 kilometers. There are 1,980 prairie dog burrows in the fields. What is

Simora [160]

The first thing we are going to do is find the area of the field. To do this we are going to use the area of a square formula: $A=s^2$
Were
$A$ is the area in square kilometers
$s$ is one of the sides of the square
We know for our problem that the side lengths of the field are 0.9 kilometers, so $s=0.9$ . Lets replace that value in our formula to find $A$ :
$A=(0.9)^2$
$A=0.81$

Now, to find the population density of the filed, we are going to use the population density formula: $P_{d}= \frac{I}{A}$
where
$P_{d}$ is the population density in <span>in burrows per square kilometer
</span> $I$ is the number of burrows
$A$ is the are of the field
We know that $I=1980$ and $A=0.81$ , so lets replace those values in our formula:
$P_{d}= \frac{1980}{0.81}$
$P_{d}=2444.4$

We can conclude that the <span>density of prairie dog burrows is approximately 2444 burrws per square kilometer.</span>

HELP!!!! if you answer you get 20 points.

Answer:

Very last choice is the answer.

Step-by-step explanation:

Remark

The thing that is most important is that the horizontal line connect h and the radius is parallel to the cut of the sphere if it was placed right in the middle. That line swings around as though the center was a pivot.

Solution

So what you have is a circle when that line goes around that part of the sphere.
To find the length of that line, use the Pythagorean Theorem. Call the line r1.
r1 ^2 = r^2 - h^2
So the area is pi * r1^2
Area = pi (r^2 - h^2)
The very last one is the answer.
