Answer Z = -1/4
Step-by-step explanation:
-1/3+2z= -5/6
Add 1/3 to both sides
-1/3+2z+1/3 = -5/6+1/3
Simplify
2z=-1/2
Divide both sides by 2
2z/2 = -1/2/2
Simplify
z = -1/4
Answer:
15
Step-by-step explanation:
8+8 would be the doubles and that would equal 16.
Then take one away from 16 and that would equal 15
Answer:
12 cm
Step-by-step explanation:
The question is not complete Let us assume the base has a length of 15 cm and width of 10 cm.
A pyramid with a rectangular base is a rectangular pyramid. Its base is rectangular and on each side of the base, it has a triangular face known as lateral face.
The volume of a rectangular pyramid is one third of the product of the length of the base, breadth of the base and height of the pyramid given by:
Volume = (length × breadth × height) / 3
Let us assume the base has a length of 15 cm and width of 10 cm.
Given that the volume = 600 cm³.
Volume = (length × breadth × height) / 3
600 = (15 × 10 × height)/3
1800 = 150 × height
height = 1800 / 150
height = 12 cm
The answer is D)20 degrees since vertical angles equal the same
