Answer:
the rate of change of the area is Ra= 80 mm² per second
Step-by-step explanation:
the area of a rectangle (A) is
A = L * W , L= length and W= width
if the width remains constant the change in the area is only due to the change in length , thus:
ΔA = Δ( L * W ) = W * ΔL , where ΔA represents the change in area and ΔL represents the change in length
ΔA = W ΔL
denoting Δt as the time required to change, and dividing both sides by Δt
ΔA/Δt = W ΔL/Δt
where Ra=ΔA/Δt = rate of change of the area and RL=ΔL/Δt rate of change of the length.
thus
Ra = W * RL
replacing values
Ra = W * RL = 8 mm * 10 mm/second = 80 mm² /second
1 - 1/5 = 5/5 - 1/5 = 4/5
4/5 - 1/5 = 3/5
3/5 - 1/5 = 2/5
2/5 - 1/5 = 1/5
1/5 - 1/5 = 0
We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.
Answer:
The length on the blueprint for an actual length of 65 feet is 
Step-by-step explanation:
Given:
Scale of the blueprint is 
Length of one side of the house is 65 feet.
Now, as per given data;
1 foot in actual = 
on the blueprint.
Therefore, using unitary method, we can find find the length on the blueprint for an actual length of 65 feet by multiplying 65 and 
. Therefore,
Length on the blueprint for 65 feet is given as:
Therefore, the length on the blueprint for an actual length of 65 feet is

4 women, 8 men.
8-4=4.
Answer:
0
Step-by-step explanation:
You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.
