A half-acre building lot is five times as long as it is wide. What are its dimensions?

Gnoma [55]

we know that

A half-acre is equal to----------> $2,023.43\ m^{2}$

Let

x---------> the length side of the building lot

y--------> the width side of the building lot

A------> Area of the building lot

x=5y-------> equation 1

$A=2,023.43\ m^{2}$

$A=x*y$

$2,023.43=x*y$ --------> equation 2

substitute equation 1 in equation 2

$2,023.43=[5y]*y$

$5y^{2}= 2,023.43\\y^{2}= 404.686\\y= 20.11\ m$

<u>Find the value of x</u>

$x=5y---> x=5*20.11--> x=100.55 m$

therefore

<u>the answer is</u>

the dimensions of the building lot are 100.55 m* 20.11 m

Estimates of the number of cells in the human body vary over an order of magnitude. Indeed, the precise number varies from one

Amiraneli [1.4K]

Answer:

a) 2.00 × 10¹⁰; b) 2.00 × 10¹³

Step-by-step explanation:

a) No. of cells in 1 cm³

$\text{No. of cells} =\text{1 cm}^{3} \times\left( \dfrac{\text{1 m}}{\text{100 cm}}\right )^{3} \times \left (\dfrac{1 \, \mu \text{m} }{10^{-6}\,\text{ m}}\right )^{3} \times \dfrac{\text{1 cell}}{\text{50 $\,\mu$m}^{3}} = \mathbf{2.00 \times 10^{10}} \textbf{ cells}$

b) No. of cells in 1 L

$\text{No. of cells} = \text{1 L} \times \dfrac{\text{1000 cm}^{3}}{\text{1 L}} \times \dfrac{2 \times 10^{10} \text{ cells}}{\text{1 cm}^{3}} = \mathbf{2.00 \times 10^{13}} \textbf{ cells}$

Which answers describe the end behaviors of the function modeled by the graph? f(x)=4 1/3x+3 , Select each correct answer.

bezimeni [28]

Answer:

As x decreases without bound, f(x) approaches the line y=3 .

As x increases without bound, f(x) increases without bound.

Step-by-step explanation:

From the given graph f(x), we can see that

When x increases the value of y also increases

When x decreases the y values goes close to 3 but it does not cross 3

As x goes to positive infinity , y approaches positive infinity

As x increases without bound, f(x) increases without bound.

As x goes to negative infinity, y values approaches +3

As x decreases without bound, f(x) approaches the line y=3
