How do I find the the perimeter of a triangle in a coordinate plane

Answers

To find the perimeter of a triangle, you need to find the length of each side and add all of them to find the perimeter. To find the distance between two points you use the distance formula with d as the distance between two coordinates, (x1,y1) and (x2,y2). , Hope this helps.

To find the perimeter of the triangle you have to find the number for the base and the sides. Then add them all up and you have your perimeter.

n stands for a whole number, 2n is greater than 30,5n is less than 100 what are all the numbers that n stands for please give me examples

Answers

$2n \ \textgreater \ 30\ \ \ \ |divide\ both\ sides\ by\ 2\n2n:2 \ \textgreater \ 30:2\n\boxed{n \ \textgreater \ 15}\n\n5n \ \textless \ 100\ \ \ |divide\ both\ sides\ by\ 5\n5n:5 \ \textless \ 100:5\n\boxed{n \ \textless \ 20}\n\nn \ \textgreater \ 15\ and\ n \ \textless \ 20\n\nn\in\{16;\ 17;\ 18;\ 19\}\n\nlook\ at\ the\ picture$

2n>30
5n<100

so these are in conjuction with each other so combine them
flip one
30<2n
simplify, divide both sides by 2
15<n

simplify other

5n<100
divide both sides by 5
n<20
combine 15<n and n<20

15<n and n<20
15<n<20
all whole numbers more thatn 15 and less thatn 20

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing strip must be 1/6 of a mile long. With the amount of material that has , what is the greatest possible width the land strip, in miles?

Answers

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:

$(1)/(6) *x$

We also know how big it is:

$(1)/(6) *x= (1)/(1 500)$

now, let's multiply both sides by 6:
$(6)/(6) *x= (6)/(1 500)$
$1 *x= (3)/(750)$
$x= (1)/(250)$

So the answer is that it would be $x= (1)/(250)$ miles wide
