Answer:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle, of length l and height h, is given by:

The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet.
This means that 
Estimate of the area:
To use an "easy" multiplication, lets consider
. So

Cameron determines the area of the wall to be 1423.125 square feet.
Very far from the area of 153, which means that he made a confusion with the decimal places. Thus, the correct answer is:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
Answer:
55,7425
Step-by-step explanation:
Since there are 60 minutes in one degree and 3600 seconds in one degree, the formula is:
Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600)
Here Degrees stay the same 55;
44' = 44/60 ≈ 0,733...
33" = 33/3600 ≈ 0,009166...
I've divided and added those three numbers by calculator in one operation and it shows exactly 55,7425. If you add them separately, you'll need to round the result.
Hello!
Let's make each of these ratios have a common denominator of 36.
5/36, 8/36, 6/36, 12/36
As you can see, our largest ratio is 12/36.
Therefore, our answer is D) 1:3.
I hope this helps!
