1. given
2. corresponding parts theorem
- segments AB and DB are similar
and segments BC and BE are also similar. lastly the circle at angles C and E indicate that they are congruent
3. SSA similarly theorem
AB and BC are similar and BC and BE are similar and angle C and E are congruent. also the triangles are not congruent in length so that makes them similar.

i apologize if i am incorrect i like just learned this. have a great day and good luck on your studies

The width of a rectangle is 4 meters less than its length, and the perimeter is 51 meters. Find the length and width of the rec

Monica [59]

The dimensions of the rectangle are:

Length = 14.75 m

Width = 10.75 m

<h3>What is the Perimeter of a Rectangle?</h3>

The total length of a rectangle is gotten by adding all it's side lengths together. The formula for the perimeter of a rectangle is given as:

Perimeter = 2(length+ width).

The dimensions for a rectangle is given as:

Perimeter = 51 meters

Length of rectangle = L meters

Width of rectangle = (L - 4) meters.

Therefore:

2(L + (L - 4)) = 51

2(L + L - 4) = 51

2(2L - 4) = 51

4L - 8 = 51

4L = 51 + 8

4L = 59

L = 59/4

L = 14.75

Length of rectangle = 14.75 m

Width of rectangle = (L - 4) = 14.75 - 4 = 10.75 m

Answer:

(A) The rate of change in the price of a bushel of corn in the current year is $7.

(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Step-by-step explanation:

The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.

Part A:

The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.

The formula to compute the slope is:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Consider the ordered pairs: (4, 28) and (10, 70)

Compute the slope of the line as follows:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{70-28}{10-4}\\\\=\frac{42}{6}\\\\=7$

Thus, the rate of change in the price of a bushel of corn in the current year is $7.

Part B:

The data for the price of bushels in the previous year is as follows:

Number of Bushels Price

2 10

4 20

6 30

8 40

Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:

Consider the ordered pairs: (2, 10) and (6, 30)

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{30-10}{6-2}\\\\=\frac{20}{4}\\\\=5$

The rate of change in the price of a bushel of corn in the previous year is $5.

Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Your are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another costs

irga5000 [103]

The sum of the 3 players needs to be 176.4$ since there are 3 players.(58.8$x3players) Since you already know 2 prices, you add them both up (56+62=118) and subtract the total by the 2 players (176.4$-118=58.4). Your answer should be 58.4$.
