Similarity means that the two rectangles have the same shape and proportions, but not the same size.
Set up a proportion for the two rectangles to find the missing width of rectangle B:
The numerator represents the length, and the denominator represents the width of the rectangles.
Cross multiply the fractions:
Divide both sides by 10 to get x by itself.
The width of the second rectangle is 15 centimeters.
The area of a rectangle is given by the following:
width * length
Multiply the width by the length to find the area of this rectangle.
The area of rectangle B is
450 square centimeters.
You plug it in 3(5) + 6(-2.4) = 15 + (-14.4) = 0.6.

Step-by-step explanation:
Answer:
The probability that the person gets a speeding ticket is 0.27
Step-by-step explanation:
The probability that the person receives a speeding ticket is the probability that the person passes through any of the speed limits and the radar is operating at that time.
Let is the probability that the person passes through radar and it is operating at that time is
Where
P(1) is the probability of person passes through
P(2) is probability that the radar is operating
Similarly the probabilities are calculated for other radars in the similar manner as
Thus the reuired probability of the reuired event is
