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

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

Can someone help me to find tsa of entire solid ?

o-na [289]

Step-by-step explanation:

Radius is same in both cones....

Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )

TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )

= 2816 cm^2

Total height of the solid = 52.8 cm

Height of the upper cone = 52.8 - 48 = 4.8 cm

TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )

= 827..2 cm^2

TSA of the solid = 2816 + 827.2 = 3643.2 cm^2

-3m-1<-10 or -4+2m<-14

Liono4ka [1.6K]

Answer:

m>3 or m<-5

Step-by-step explanation:

First simplify -3m-1 < -10:

-3m < -9

m > 3 (switch direction of sign when dividing by negative number)

Then simplify -4+2m<-14:

2m<-10

m<-5

m>3 or m<-5
