If he distance from the town of bree to weathertop is 8 miles on a 45 degree upward slope, what is the elevation gain (omit units)?

The elevation gain is 4√2 or 5.6569

Step-by-step explanation:

Consider the provided information.

The distance from the town of Bree to weathertop is 8 miles on a 45 degree upward slope,

The required figure is shown in figure 1.

Here, the triangle is right angle triangle with one angle 45 degree.

Thus, the measure of angles will be: 90°, 45° and 45°

Therefore, both legs of the triangle must be equal. Now by using Pythagorean Theorem,

Hence, the elevation gain is 4√2 or 5.6569

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
