- Inorganic
- Solid
- Naturally Occuring
- Ordered Internal Structure
Three ways that minerals form
- Crystalizing of Magma
- Weathering
- Metamorphosis

Answer:
136
Step-by-step explanation:
multiply 4 times 6, divide by two to get the area of the front side, then multiply that by two to get eh area of the two triangles.
Then multiply each side, two sides of 5 time 7 and one side of 6 times 7
Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
This means <u>"if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"</u>
<u />
let's cross multiply and solve for x:
<em>So width is 2/3 feet and length is 0.75 feet.</em>
<em>Converting back to inches (since we need the area in sq. inches):</em>
<em>2/3 feet = 2/3 * 12 = 8 inches, and</em>
<em>0.75 feet = 0.75 * 12 = 9 inches</em>
<em />
<em>Hence, area is 8 * 9 = 72 sq. inches.</em>
Answer:
The answer to your question is -3
Step-by-step explanation:
Data
A (-8, -35)
B (6, 21)
Process
1.- Calculate the slope
slope = m = (y2 - y1) / (x2 - x1)
x1 = -8 y1 = -35 x2 = 6 y2 = 21
-Substitution
m = (21 + 35) / (6 + 8)
-Simplification
m = 56 / 14
-Result
m = 4
2.- Calculate the equation of the line
y - y1 = m(x - x1)
-Substitution
y + 35 = 4(x + 8)
-Simplification
y + 35 = 4x + 32
y = 4x + 32 - 35
-Result
y = 4x - 3
3.- Find the y-intercept
The y-intercept is the number after the x, for this equation is -3.
Answer:
and 
Step-by-step explanation:
If two or more angles have the same terminal side when in standard position, then they are coterminal.
To find a positive angle that is coterminal with 
, we add 
, that is one complete positive revolution t get:
To find a negative angle that is coterminal with , we subtract , that is one complete negative revolution t get:
