Answer:
The coordinates of P is (-1,5.5)
Step-by-step explanation:
Here, we want to find the coordinates of the point that divides the segment into the ratio 1 to 3
To do this, we are going to use the section formula
We have this as;
(x,y) = (nx1 + mx2)/m+ n, (ny1 + my2)/m + n
where m = 1 , n = 3
(x1,y1) = (-3,4)
(x2,y2) = (5,10)
Substituting these values, we have;
(x,y) = (3(-3) + 1(5)/4 , (3(4) + 1(10)/4
(x,y) = (-9+ 5)/4 , (12 + 10)/4
(x,y) = (-1, 5.5)
In a triangle, if the sum of the squares of 2 shortest sides is less than the square of the third side, (as is the case here), the triangle is obtuse.
So, IF a and b are the 2 shortest sides then this is true.

Answer:
Her actual distance for the trip will be 112.5 miles.
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the scale of the map Kelsey is reading is:
And according to the exercise, Kelsey's trip measures 4.5 inches on that map.
Therefore, in order to calculate what will be her actual distance for the trip (Let be this distance), you can set up the following proportion:
Finally, you must solve for . Then, you get:
Therefore, her actual distance for the trip will be 112.5 miles

Answer:
the length is 84 ft
Step-by-step explanation:
65*2= 130
298-130=168
168/2=84
84+84+65+65=298 ft
