Hey there! :)

Answer:

13 packages.

Step-by-step explanation:

Begin by finding the total area of this composite figure. Separate the figure into separate rectangles. Use the formula A = l × w to calculate the area of each:

Smaller rectangle:

Subtract 7 from 9 to find the width:

9 -7 = 2. Therefore:

2 × 2 = 4 ft².

Larger rectangle:

7 × 5 = 35 ft².

Add up the two areas to find the area of the entire figure:

4 + 35 = 39 ft².

If each package of tile covers 3 ft², simply divide to find the package of tiles needed:

39 / 3 = 13 packages.

Answer:

y=0.46591x+7.71591

Step-by-step explanation:

Labelled points are (21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2)

Slope of line (m) =\frac{27.75-17.5}{43-21}  =\frac{10.25}{22} =\frac{41}{88}

Equation of line in point - slope form is given as:

y-y_1 = m(x-x_1)

\therefore y-17.5= \frac{41}{88} (x-21)

\therefore y= \frac{41}{88} x-\frac{861}{88}+17.5

\therefore y= \frac{41}{88} x+17.5-\frac{861}{88}

\therefore y= \frac{41}{88} x+\frac{1,540-861}{88}

\therefore y= \frac{41}{88} x+\frac{679}{88}

\therefore y=0.465909091x+7.71590909

\therefore y=0.46591x+7.71591

If the total operating cost for a 20-acre organic strawberry farm is $551,520, how many acres are on a farm with a total operati
larisa86 [58]

Answer:

16 acres

Step-by-step explanation:

First find the operating cost for 1 acre.  Find that by dividing $551,520 by 20 acres.  That gives us $27,576 per acre.  Now we can set up a proportion to solve for the number of acres that have an operating cost of $441,216:

\frac{cost}{acre}:\frac{27,576}{1}=\frac{441,216}{x}

Cross multiply to get:

27576x = 441216 so

x = 16

We did not have to find the cost per acre to solve this.  We could have set up the proportion with $551,520 on the top of the ratio and 20 on the bottom and we would still have gotten the same answer.  I just figured the numbers wouldn't be as large if we divided to find the cost per unit.
