Answer:

Figure 4: Square

Figure 1: Parallelogram

Figure 2: Rectangle

Step-by-step explanation:

Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.

Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.

Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.

Use the information given to enter an equation in standard form.

Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17

Kamila has a rectangular lawn that measures 80 by 150 feet. She wants to lay gravel made from colored rock in a border, 6 feet w

Zarrin [17]

Part 1) Create a diagram that shows Kamila’s rectangular lawn and the gravel border. Assign variables to any unknown sides and label the diagram

see the attached figure

Part 2)Use your diagram to determine how many square feet of the gravel border will surround the lawn

area of the border=[162*92]-[150*80]----> 14904-12000-----> 2904 ft²

Part 3) Kamila decided that the depth of the gravel needs to be 2 inches. What is the total volume of gravel needed for the border?

we know that
1 ft-------> 12 in
x--------> 2 in
x=2/12------> x=0.17 ft

volume of gravel needed=area of the border*deep of the gravel
volume of gravel needed=2904*0.17----> 493.68 ft³

Part 4)A large bag of colored rock contains a cubic yard and costs $30. What is the total cost of the rocks needed for the border?

1 yd³--------> 27 ft³
x---------> 493.68 ft³
x=493.68/27-----> 18.28 yd³

if 1 yd³----------> cost $30
18.28 yd³------> x
x=18.28*30------> x=$548.53

the answer Part 4) is
$548.53

A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could represe

Cerrena [4.2K]

Answer:

B. y= -x^2 + 50x - 300

Step-by-step explanation:

Options given

A. y^2=4x^2 - 100

B. y= -x^2 + 50x - 300

C. x= -y^2 - 400

D. x^2= -6y^2 + 200

We are to find profits (y) function in thousands of dollars if the company sells x items.

We will use elimination method to eliminate the wrong options above in order to find the correct answer

Option A. y^2= 4x^2 - 100 is used to find the square of the profit function

Option B. y= -x^2 + 50x - 300 is used to calculate profit (y) function

Option C. x= -y^2 - 400 is for the calculation of the items x sold

Option D. x^2= -6y^2 + 200 is to find items x sold squared.

Since, we are required to find the profit (y) function, option A, C and D will be eliminated.

We are left with option B which is the correct answer to the question.

The weekly profits (y) function in thousands of dollars when the company sells x items is

B. y= -x^2 + 50x - 300
