Molly can prepare a report in 6 hours. Jere can prepare a report in only 4 hours.
mrs_skeptik [129]

Answer with explanation:

Time taken by Molly to prepare the Report = 6 hours

Work done in 1 hour =\frac{1}{6}

Time taken by Jere to prepare the Report = 4 hours

Work done in 1 hour =\frac{1}{4}

Their Combined Work , is given by the equation

          =\frac{1}{6}+\frac{1}{4}\\\\=\frac{6+4}{6\times 4}\\\\=\frac{10}{24}

Time it would take for Molly and Jere to prepare a report together is equal to

       =\frac{24}{10}\\\\=2.4

= 2.4 hours

6. A catalog sells two different shaped tablecloths. One is a square with sides
user100 [1]
Square has 4 sides that are each 12 feet long, therefore the total perimeter of the square is 48. (12+12+12+12 or 12x4)

Hexagon has 6 sides. If each side is equal to another, the total perimeter of the square must equal the total perimeter of the hexagon. 

Perimeter = 48. Hexagon with 6 sides, therefore you divide 48/6 to find the length of each side. In this case, 48/6 = 8. 

So, each side of the hexagon tablecloth is 8 feet long.
