Which value for x would make the perimeter of this rectangle equal 48 inches
RSB [31]

Answer:

L = 16; W=8: are the correct values.

Step-by-step explanation:

Start off with 2 math statements:

First, for the perimeter:  2W x 2L = 48

Then, for the area:  W x L = 128

Next, we want to take the 2nd equation; then solve it for "W"

W x L = 128

Divide out both sides by "L", to get the "W" equals:

W = 128/L

Next, go back to the first equation.  Where it indicates "W", put in the value of:  128/L in its place; to get:

2L + 2*(128/L) = 48; which gives us:

2L + 256/L = 48

Multiply everything by "L", to get:

2L2 + 256 = 48L

Next, divide out everything by 2, to get:

L2 + 128 = 24L

Next, move the 24L over to the left, to get:

L2 - 24L + 128 = 0

(L-16)* (L-8) = 0

L-16 = 0; L-8 = 0

Which gives us:  L=16; L=8

Let's go with the L=16 first; back into the original equation:

f(16) = 2*16 + 2W = 48

32 + 2W = 48

-=32         -32

2W = 16

Divide out both sides by 2, to get:

W = 8

Next, test our values, by plugging them back into both original equations:

2*16 + 2*8 = 48

32 + 16 = 48        [Check]

L x W = 128

16 * 8 = 128

128 = 128          [Check]

bacteria colonies can triple in size every 4 days. if you start with 40 bacteria microorganisms, how large would the colony be a
Westkost [7]

<span>Assuming the reaction is of 1st order, we can start using the formula for rate of 1st order reaction:</span>

dN / dt = k * N

Rearranging,

dN / N = k dt

Where N = amount of sample, k = rate constant, t = time

Integrating the equation from N = Ni to Nf and t = ti to tf will result in:

ln (Nf / Ni) = k (tf – ti)

Since k is constant, we can equate to situations. Situation 1 is triple in size every days, situation 2 is after 20 days.

ln (Nf / Ni) / (tf – ti) = k

ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20

Calculating for Nf,

<span>Nf = 9,720 bacteria </span>

6) A demand curve for a product is the number of items the consumer will buy at different prices. At a price of $2 a store can s
ExtremeBDS [4]

Given :

When price is $2 dollars he sells 2400 units .

When price is $8 dollars he sells 600 units .

To Find :

If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.

Solution :

Two points are given :

(x_1,y_1)=(2,2400)

(x_2,y_2)=(8,600)

Now , slope is given by :

m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300

Now , the equation of line containing these two points and slope -300 is :

(y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000

Therefore , equation for the demand curve is y = -300x +3000 .

Hence , this is the required solution .
