A rectangular flower bed covers an area of 11.76 square feet in the garden. The width of the flower bed is 3.5 feet less than it
Degger [83]
The length and width of the garden will be obtain as follows:
let the length be x ft, the width will be (x+3.5)ft
area of the bed will be:
A=length*width
11.76=x(x+3.5)
11.76=x^2+3.5x
thus
x^2+3.5x-11.76=0
solving this by quadratic formula we get:
x=[-b+/-sqrt(b^2-4ac)]/2a
thus plugging in the values we obtain
x=[-3.5+/-sqrt(3.5^2-4(-11.76*1))]/2
x=[-3.5+/-sqrt59.29]/2
x=[-3.5+/-7.7]/2
x=4.2 or -11.2
thus the length will be x=4.2 ft and the width will be x-3.5=0.7 ft

Which size container of cold farm ice cream is the better deal for Sheldon? Explain.
Art [367]

<u>Cold Farms: </u>

<u>Small box </u>

1 pint = $2.50

1 quart = $4.50

<u>Large Box</u>

1 quart = 2 pints .

2 pints  = $4.50

1 pint = $4.50 / 2 = $2.25

<u>Cone Dreams:</u>

<u>Small box </u>

1 quart = $4.25 and

1 pint = $4.25/2 =  $ 2.125

<u>Large Box</u>

1 gallon = $9.50.

1 gallon = 8 pints

8 pints = $9.50.

1 pint = $9.50 / 8 = $ 1.1875.


<h3>15) Therefore, large size container of Cold Farms ice cream is better deal for Sheldon because it cost $2.25 per pint of ice cream as compared to small box cost $2.50 per pint.</h3><h3 /><h3>16) Cone Dreams Large size container cost just $ 1.1875 per pint of ice cream. So, Cone Dreams Large size container is best deal.</h3>
