Answer:
30
Step-by-step explanation:
This problem can be done without the Distance Formula (which is a way to find the distance between any two points in the plane).
The attached image shows the points and segments joining them.
PQ = 5 because the points are on the same horizontal line, and you can count spaces between them (or subtract x-coordinates: 4 - (-1) = 5).
PR = 12 because the points are on the same vertical line; count spaces or subtract y-coordinates, 7 - (-5) = 12.
The triangle is a right triangle, so the Pythagorean Theorem can be used to find the length of the hypotenuse.
![(\text{leg})^2+(\text{leg})^2=(\text{hypotenuse})^2](https://tex.z-dn.net/?f=%28%5Ctext%7Bleg%7D%29%5E2%2B%28%5Ctext%7Bleg%7D%29%5E2%3D%28%5Ctext%7Bhypotenuse%7D%29%5E2)
![(QR)^2=5^2+12^2=25+144=169\\QR=\sqrt{169}=13](https://tex.z-dn.net/?f=%28QR%29%5E2%3D5%5E2%2B12%5E2%3D25%2B144%3D169%5C%5CQR%3D%5Csqrt%7B169%7D%3D13)
The perimeter of the triangle is 5 + 12 + 13 = 30
Answer:
148
Step-by-step explanation:
5 times 29.6
X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
