Answer:
81 m^2
Step-by-step explanation:
First find the area of the lower rectangle
A = l*w
A = 12* 5 = 60m^2
Then we find the area of the middle rectangle
The height is 4m - 3m = 1 meter
The length is 12m - 3m = 9m
A = 9*1 = 9m^2
Then we find the area of the top rectangle
The length is 4 m and the width is 3 m
A = 3*4 = 12m^2
The total area is 60+9+12 =81 m^2

Answer:
The temperature outside is 75.6°F
Step-by-step explanation:
We are given the following in the question:
The temperature of dry ice = - 109.3°F
Let x be the temperature outside in Fahrenheit.
It is given that the temperature of dry ice is 184.9°F less than the outside temperature.
Thus, we can write the equation:

Step-by-step explanation:
Given that:
Probability of DVD player breaking down before the warranty expires = 0.034
To find:
The probability that the player will not break down before the warranty expires = ?
Solution:
Here, The two events are:
1. The DVD player breaks down before the warranty gets expired.
2. The DVD player breaks down after the warranty gets expired
In other words, the 2nd event can be stated as:
The DVD does not break down before the warranty gets expired.
The two events here, have nothing in common i.e. they are mutually exclusive events.
So, Sum of their probabilities will be equal to 1.
