Farmer Donald is selling two parcels of land together. One of the parcels is one square mile and the other parcel is five acres.
Julli [10]

Answer:

The answer to your question is: c) $1354500

Step-by-step explanation:

Data:

Parcel1 = P1 = 1 mi2

Parcel2= P2= 5 acres

Price = $2100 / acre

Total price =

Need to convert 1 mi2 to acres

            1 acre ------------------------ 0.001563 mi2

           x         -------------------------  1 mi2

 x = 639.8 acres

Now  

              1 acre ------------------------- $2100

            639.8 acres -----------------     x

Parcel 1 cost  = $1343580

              1 acre ------------------------- $2100

               5 acres ---------------------   x

        x = 10500

Total cost = cost P1 + cost P2

Total cost = $1343580 + $10500 = $ 1354080   The closest is letter c

write the equation of the line, in standard form, that passes through the origin and is parallel to x+y=6. include your work in
tankabanditka [31]
To solve this problem you must apply the proccedure shown below:
 You have that the line is <span>parallel to x+y=6, this means that both  lines have the same slope. You can calculate the slope as below:
 y=mx+b
 m is the slope and b is the y-intercept

 x+y=6
 y=-x+6
 The slope is m=-1

 As the line passes through the origin, b=0, therefore, you have:
 y=-x+0
 y=-x
 x+y=0

 The answer is: </span>x+y=0

Pls help this is due in an hour!! thank you

Well, we know that it costs $60 plus 5 per month for Alpha Fitness Club.

We also know that it costs $20 plus 10 per month for Omega Fitness Club.

In order to find out which one would cost the most, we must add the additional costs to the original join cost.

(NEVER add the join cost, just do the join cost at the beginning or else the clubs will never become the same cost.)

Club      M1  M2  M3  M4  M5  M6  M7  M8  M9

Alpha:   60   65  70   75   80   85   90  95  100

Omega:20   30  40   50   60   70   80  90  100

If you look above, you realize that there is a time when they both cost the same.

Summary sentence:

After 9 months, the cost to belong to either fitness club would be $100.
