The area of a playground is 336 yd2. The width of the playground is 5 yd longer than its length. Find the length and width of th
kondaur [170]
L=16
W=21

Set up a systems of equations: 
x=length 
y=width 

xy=336
x+5=y

Use substitution to solve: 
x(x+5)=336
x^2+5x=336 

Solve using factoring: 
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21 
Since length can't be negative, l=16 

To find width, plug length into the first equation: 
(16)y=336
y=21 

So...
L=16
<span>W=21</span>

Answer:

<h2>203.5 </h2>

Solution,

Onions less than 60 grams = 2 --> Pickling

Onions greater than 120 grams = 5 + 3 = 8 --> Market

Onions between 60 and 120 = 13---> Processing

Total frequency = 2 + 8 + 13 = 23

Now,

x =  \frac{13}{23}  \times 360

x = 203.48

x = 203.5

Hope this helps ..

Good luck on your assignment...

hodyreva [135]

We assume you intend

D(h)=35e^{-0.15h}

You want to evaluate this function for h=0 and h=8.

D(0)=35e^{0}=35\\D(8)=35e^{-0.15\cdot 8}\approx 10.54

The amount injected was 35 milligrams; 8 hours later 10.54 milligrams remained.
