The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of va

kow [346]

Answer:

$16\ acres$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

substitute the values of x and y

$k=\frac{551,520}{20}=\$27,576\ per\ acre$

The linear equation is equal to

$y=27,576x$

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

Two numbers are in the ratio of 10:6 if they differ by 36 what are the numbers

Simora [160]

Answer:

51.4 and 15.42

Step-by-step explanation:

let 1st No=10x

2nd No=3x

10x-3x=36

7x=36

x=36/7=5.14

1st No=10x

=10×5.14

=51.4

2nd No=3x

=3×5.14

=15.42

Therefore the numbers are 51.4 and 15.42

What is the sum ? (2x^2-4x+1)+(5x+x^2-1)

Ipatiy [6.2K]

$Hello$ $There!$

The answer is...

$3x^2+x$

HERE'S A EXPLANATION!

$2x^2-4x+1+5x+x^2-1$

$=2x^2+-4x+1+5x+x^2+-1$

Combine these like terms!

$=2x^2+-4x+1+5x+x^2+-1$

$=(2x^2+x^2)+(-4x+5x)+(1+-1)$

$=3x^2+x$

ANSWER!

$=3x^2+x$

Hopefully, this helps you!!
