Ethan's school has a sports field with an area of 6,450.35 square yards. If the length of the field is 90.85 yards, what is the width of the field?

71 yards.

Explanation:

Since the field is rectangular in shape, the formula for finding the Area is L * W

where L = length, and W = width

From the question Area of the sport field = 6,450.35 square yards

this implies that L*W = 6,450.35 square yards

Also, given that the length of the field L = 90.85 yards

Therefore from the equation 90.85W = 6,450.35 square yards

W = 6,450.35 square yards ÷ 90.85 yards

W = 71 yards

Hence, the Width of the sport field is 71 yards.

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
