40 POINTS. When they form conical piles, granular materials such as salt, gravel, and sand settle at different "angles of repose

grandymaker [24]

Answer:

34.0 degrees, 29.6 feet in Diameter.

This is a right triangle trigonometry question.

Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.

Use Inverse Tangent function to find the angle of repose

round to 34.0

then use the angle of repose to solve trigonometric function of the tangent for the radius of the other cone.

switch denominator and tangent

multiply by 2 to get diameter of second cone

14.82*2≈29.6

hopefully this helps!

Coordinates (-3, 5), ( -3, 8), and (2, 5). The triangles was dilated by a scale favtor of 3. What is the area of the dilated tri

Otrada [13]

Answer:

The area of the triangle is 7.5 unit²

Step-by-step explanation:

Here we have the coordinates given as

(-3, 5) (-3, 8) and (2, 5)

Let us call the points A = (-3, 5)

B = (-3, 8) and

C = (2, 5)

Therefore the lengths of the sides of the triangle are

AB = a = $\sqrt{(-3-(-3))^2+(5-8)^2} = 3$

AC = b = $\sqrt{(-3-2)^2+(5-5)^2} = 5$

BC = c = $\sqrt{(-3-2)^2+(8-5)^2} = \sqrt{34}$

Therefore the Area can be derived from Heron's formula which is

A = $\sqrt{s\times (s-a)\times (s-b)\times (s-c)}$ where s = semi perimeter or (a + b + c)/2

Therefore, plugging the values, we get

s = (3 + 5 + √34)/2 = 6.9155≈6.92

A = $\sqrt{6.92\times (6.92-3)\times (6.92-5)\times (6.92-\sqrt{34} )}$ = 7.499≈7.5.
