A school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden.
Len [333]

Answer:

18\frac{3}{4} pounds.  

Step-by-step explanation:

Let x be the total amount of potting soil needed to complete the planting in new garden.    

We are told that a school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden. This means 2/5 of x equals to 12 1/2.

\frac{2}{5} x=12\frac{1}{2}

\frac{2}{5} x=\frac{25}{2}  

x=\frac{25}{2}\times\frac{5}{2}

x=\frac{125}{4}

To find the amount of soil needed for the next of planting we will subtract the amount of potting soil used on the first day (\frac{25}{2}) from amount of total potting soil (\frac{125}{4}).

\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25}{2}

\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25\times 2}{2\times2}

\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{50}{4}

\text{Amount of potting soil needed for second day}=\frac{75}{4}

\text{Amount of potting soil needed for second day}=\frac{75}{4}=18\frac{3}{4}

Therefore, the group will need 18\frac{3}{4} pounds of potting soil to finish their work.

Given the roll of paper towels below how much plastic would be needed to cover the role so it can be sold given the diameter of
gladu [14]

Answer:

Amount of plastic need to cover paper role = 565.2 inches

Step-by-step explanation:

Given:

Diameter of paper role = 10 inch

Height of paper role = 13 inch

Find:

Amount of plastic need to cover paper role

Computation:

Radius of paper role = Diameter of paper role / 2

Radius of paper role = 10 / 2

Radius of paper role = 5 inch

Amount of plastic need to cover paper role = Total surface area of cylinder

Amount of plastic need to cover paper role = 2πr(h+r)

Amount of plastic need to cover paper role = 2(3.14)(5)(13+5)

Amount of plastic need to cover paper role = (3.14)(10)(18)

Amount of plastic need to cover paper role = 565.2 inches
