Answer:
9.12 m^2
Step-by-step explanation:
14*.305=4.27 m
7*.305= 2.135m
multiplied together is 9.12 m^2
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:
Were
is the area in square kilometers
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
. Lets replace that value in our formula to find
:
Now, to find the population density of the filed, we are going to use the population density formula:
where
is the population density in <span>in burrows per square kilometer
</span>
is the number of burrows
is the are of the field
We know that
and
, so lets replace those values in our formula:
We can conclude that the <span>density of prairie dog burrows is approximately
2444 burrws per square kilometer.</span>
Well you have to substitute the 4 in for X. It would make the equation: 3(4)+6=18. (Multiply 3 and 4)
12+6=18 (Add 12 and 6)
18=18
Hope this helped :)
15-(5)/5-10=10/-5=-2 hope it helps!
Alright, so let's make a function for the number of seats in a row. Number of seats = 25+ (number of row-1)(2) because it goes up by two. We start with 25, so we have that, then we get that it adds by 2 every row. However, for the first row it only has 25, so we have the number of the row -1 .If we figure out the 200th row, we get 25+398=423. Adding that and 25, we get 448. 448*100=44800, and we get that number because with an even number of rows, we add the 1st and 200th, the 2nd and 99th, and so on. This works because as you go up rows, you add two, and as you decrease rows, you decrease by two, so they cancel each other out and form 100 pairs. All pairs are equal.
