Fiona's school is in the shape of a triangle, with three hallways connecting the corners. Fiona enters the building and walks 90
noname [10]

Answer:

between 30 yards and 150 yards

Step-by-step explanation:

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ----> the possible lengths of the third hallway in yards

<em>Applying the Triangle Inequality Theorem</em>

1) 90+60 > x

150 > x

Rewrite

x < 150 yd

2) 60+x> 90

x > 90-60

x > 30 yd

The possible lengths of the third hallway in yards is the interval

(30,150)

All real numbers greater than 30 yards and less than 150 yards

therefore

between 30 yards and 150 yards

A line goes through points (-2, 18) and (4, 3). What is the slope of the line?
sineoko [7]

Answer:

-2.5

Step-by-step explanation:

The slope can be found by

m = (y2-y1)/(x2-x1)

   = (3-18)/(4- -2)

   = -15/(4+2)

    =-15/6

    = -5/2

     -2.5
