Answer:

3.5 %

Step-by-step explanation:

508.75 - 500 = 8.75

8.75 = (500) (0.5)

8.75/250 = (250)/250

.035

Move the decimal two places to the right to get 3.5%.

Hope this helps and best of luck!

quester [9]

Answer:

x^2-50x+456=0

Step-by-step explanation:

GIVEN: A 100\text{ foot} fence is used to enclose a rectangular land plot. If the area of the land plot is 456\text{ feet}^2.

TO FIND: equation to determine the length x of the land plot.

SOLUTION:

total length of fence =100\text{ foot}

let the width of land plot be y

perimeter of plot =2(x+y)=100

                            x+y=50

area of rectangular plot =\text{length}\times\text{breadth}

                                       xy=456

                                      y=\frac{456}{x}

putting value of y

x+\frac{456}{x}=50

x^2-50x+456=0

Hence required equation to get length x of land plot is x^2-50x+456=0

on solving

x=38,12

possible length of land plot is 38\text{ foot} and 12\text{ foot}
