Answer:
Length of the rectangle is = 8 inches.
Step-by-step explanation:
Given :
Area of square = Area of the rectangle
According to the question:
Length of the square be 'x'.
Its area = (Side)*(Side) =
...equation (i)
Length of the rectangle = 
Width of the rectangle = 
Area of the rectangle =Length * Width
⇒
⇒
...equation (ii)
Equating both the equation as area of both the figure are equal.
⇒ 
⇒
...subtracting
both sides
⇒
...dividing both sides with 2
⇒
inches
Plugging the value of x=4 in the length of the rectangle.
We have,
⇒
So the length of the rectangle = 8 inches.
Answer:
First one should be 3 1/4 or 3.25
Step-by-step explanation:
What you do is count up the lines so in this case we have 4 lines so we do 100/4 = 25 so each line is 0.25 or 1/4 and since it's after 3 it should be 3 1/4 or 3.25
P(success) = 0.4 P(failure) = 0.6
8C2 (0.4)² * (0.6)^6
P(2 success) =0.290
