The area of a rectangle pool is 192 square meters. The lenght of the pool is 4 meters more than its width. Find the length and w

weqwewe [10]

Answer:

Step-by-step explanation:

The length of the pool is 4 meters more than its width

Let x and (x + 4m) represent the width and length respectively

x(x+4m) = 192 m^2

solving for x

x^2 + 4m - 192 m^2 = 0

factoring

(x+16)(x-12)=0 |OR x+=+%28-4+%2B-+28%29%2F%282%29+ using Quadratic Formula

(x+16)=0 tossing out negative solution for measure

(x-12)=0 x = 12m, the width. The length is 16m (12m+4m)

coldgirl [10]

(a) $P(4\ out\ of\ 4)=0.8^{4}=0.4096$

(b)
$P(2\ out\ of\ 4)=4C2\times 0.8^{2}\times0.2^{2}=0.1536$
$P(3\ out\ of\ 4)=4C3\times0.8^{3}\times0.2=0.4096$
P(4 out of 4)=0.4096
P(at least 2) = 0.1536 + 0.4096 + 0.4096 = 0.9728

demand for a brand of clock radio is given by p+3q=390 , and the supply for these radios is given by p=7q=90 , where is the pric

umka2103 [35]

Answer:

p=$300 and q=30 clock radio

Step-by-step explanation:

we have

p ----> is the price

q ----> is the quantity

$p+3q=390$ ----> equation A

$p-7q=90$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The intersection point is (300,30)

see the attached figure

therefore

The solution is

p=$300

q=30 clock radio
