A rectangular parcel of land has an area of 3,000 ft2. A diagonal between opposite corners is measured to be 10 ft longer than o
Kazeer [188]

Answer:

40 ft × 75 ft

Step-by-step explanation:

Let x be the one side ( in feet ) of the rectangular parcel,

So, the diagonal between opposite corners = ( x + 10 ) feet,

Let y be the other side of the rectangle ( adjacent to side x ),

The area of the rectangle,

A = x × y,

According to the question,

A = 3000 square ft,

\implies xy = 3000\implies y=\frac{3000}{x}

∵ In a rectangle,

D^2=a^2+b^2

Where, a and b are the adjacent side of the rectangle and D is the diagonal,

(x+10)^2 = x^2 + y^2

(x+10)^2 = x^2 + \frac{9000000}{x^2}

x^2(x+10)^2 = x^4 + 9000000

x^2(x^2+100+20x) = x^4 + 9000000

x^4+100x^2 + 20x^3 = x^4 + 9000000

20x^3 + 100x^2 - 9000000=0

x^3 + 5x^2 - 450000 = 0

By graphing the equation,

We found that,

The only real zeros of the equation is at x = 75,

Hence, the one side of the rectangle = 75 ft,

And, second side = \frac{3000}{75} = 40 ft

Hence, the dimension of the land is 40 ft × 75 ft

PLEASE HELP THANKS SO MUCH!

Surface area = sum of 2 triangles + sum of the 3 rectangles

= 2 * 84 + 18*24 + 18*25 + 18*7 =  1176 ft^2

volume = 1/2*7 *24 * 18  =  1512 ft^3
surface area to volume = 1176:1512 =  0.78 which is less than 1.
so the company wil manufacture it.

Q.16 please<br> With steps
blsea [12.9K]

The equations

2x^2+9x-5=0

and

2\left(t-\dfrac12\right)^2+9\left(t-\dfrac12\right)-5=0

are really the same, we're just setting x=t-\dfrac12, or t=x+\dfrac12.

2x^2+9x-5=(2x-1)(x+5)=0\implies x=\dfrac12,x=-5

So we get

t=\dfrac12+\dfrac12=1,t=-5+\dfrac12=-\dfrac92

What is the area of the figure:
Luba_88 [7]

For this case we have that the area of the triangle is given by:

A = \frac {b * h} {2}

Where:

b: It's the base

h: It's the height

We have to:

cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}

The atura will be given by:

sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}

So, the area is:

A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144

Answer:

144
