Answer:

AA (Angle-Angle): If triangles have two of the same angles, then the triangles are similar. SAS (Side-Angle-Side): If triangles have two pairs of proportional sides and equal included angles, then the triangles are similar.

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.

5 pigs: 3 chickens

pigs have four feet, so if 20 feet belong to the pigs, there's 5 pigs, because 5x4=20.
chickens have 2 feet, so if 6 feet belong to the chickens, there's 3 chickens, because 2x3=6.

3. A straight line passes through two points with
kirza4 [7]

Answer:

Step-by-step explanation:

Find the slope of the line

(x₁ , y₁) = (6 , 8)   & (x₂ , y₂) = (0 , 5)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{5-8}{0-6}\\\\=\frac{-3}{-6}\\\\=\frac{1}{2}

m = 1/2  ;(x₁ , y₁) = (6 , 8)

y - y₁ = m(x - x₁)

y - 8 = \frac{1}{2}(x - 6)\\\\y - 8 =\frac{1}{2}x -\frac{1}{2}*6\\\\y - 8 =\frac{1}{2}x- 3\\\\y = \frac{1}{2}x - 3 + 8\\\\y = \frac{1}{2}x + 5
