Answer:
s/(1-r)=R
Step-by-step explanation:
S=R-rR
S=R(1-r)
s/(1-r)=R

Answer: 40 cubic cm</h3>
=====================================================
Explanation:
The triangular face has area of base*height/2 = 4*10/2 = 40/2 = 20 square cm.
Multiply this prism base area by the depth of the prism to get 20*2 = 40 cubic cm.
It might help to place the triangular prism so the triangular face is along the ground, so you can think of that face as the floor of this triangular room. The volume of this room is equal to the floor area times the height of the room.
volume of the room = (floor area)*(height of the room)
volume of the prism = (base area)*(height of the prism)
For any prism, the base faces are always parallel and congruent to each other.

It's 5
Step-by-step explanation:
Good Luck
Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.
Using the binomial distribution, we want all three to be defective.
Refer to the attached image.
Let the height of the Empire State Building = BC = 'x'
John is standing at distance from Empire State Building = AB = 1 mile
The angle of elevation = 11°
In triangle ABC,
Consider
x = 0.194 mile
Since 1 mile =5280 feet
So, x =
= 1024.32 feet.
So, the height of the Empire State Building is 1024.32 feet.
