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.
The square root of 13+29 is <span>6.48074069841 but, you can simply put 6.4</span>
Howdy,
20% is also 1/5 in fraction form, which tells us he spent 1/5 of his money on clothes:
So to solve, we have to multiply 50 by 5:
50 x 5 = 250
