Answer:
Step-by-step explanation:
The inside of a refrigerator is 17 x 18 x 42 inch, to calculate the samples that would fit in the refrigerator is calculating the volume which is length x breadth x height
You can opt to calculate the volume in inch ^3 or cm^3
Both will be discussed here
In inch^3
Volume= 17 × 18 × 42 = 306 x 42= 12852in ^3
In cm^3
Convert inch to cm
I inch is 2.54cm
17 inch = 43.18cm
18 inch = 45.72cm
42 inch = 106.68cm
Volume = 43.18 × 45.72 × 106.68 = 210606.546528cm^3
210606.55cm^3 approximately
For this case we must compare the following expressions:

We convert the mixed number to a fraction:

So, we have to compare:
1.2 and 1.2
It is observed that the expressions are equal, so we have the sign of equality "=":

Answer:

<u>Given</u>:
The number 12 is the geometric mean between 3 and a number x.
We need to determine the value of x.
<u>Value of x:</u>
Since, we know that the geometric mean is the square root of the product of two numbers.
Hence, we have;

where a and b are two positive numbers.
Substituting Geometric mean = 12, a = 3 and b = x, we get;

Squaring on both sides, we get;


Dividing both sides of the equation by 3, we have;

Thus, the value of x is 48.
