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.
wolverine [178]

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.
