Lets say she cuts squares of x by x in length.
Area of bottom will be (20 - 2x)(11 - 2x) = 80 inches squared
220 - 40x - 22x + 4x^2 = 80
4x^2 - 62x + 140 = 0
x^2 - 15.5x + 35 = 0
Using quadratic equation;
you get x = 2.743753901 0r 12.7562461 inches
The length of the square cannot be more than 11 inches
So the only squares you can cut are:
2.743753901 inches by 2.743753901 inches squares.
Answer:
1.) 18 is decreasing by 83%
2.) 16 is decreasing by 12.5%
Step-by-step explanation:
Part ÷ Whole = Percent (decimal form)
1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.
2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.

\left[x \right] = \left[ \frac{9}{2}\right][x]=[29] solution set of the equation
Y=mx+b, the b is your y-intercept so just rearrange your equation
y=(3/7)x+(2/7)
your y-intercept would be b) (2/7)
