An equilateral triangle has a perimeter of 18 feet. If a square whose sides have the same length as one side of the triangle is

built, what will be the area of the square?

Answer:

36 ft²

Step-by-step explanation:

equilateral means all sides are equally long.

a triangle has 3 sides.

in our case they are all equally long.

and their sum (all 3 sides together) is the perimeter

P = 18 = 3 × side length

side length = 18/3 = 6 ft

a square with the same side length (6) had then an area of

side length × side length = 6×6 = 6² = 36 ft²

it is important to remember : a length is measured e.g. in feet (ft). an area is then meshed in square-feet (ft²). it is important to add this to the calculated numbers to express the right dimension of these numbers.

The least square regression equation for the information provided is y = 9.72x - 40.776

<u>The general equation of a regression model can be expressed thus</u>:

  • y = bx + c

  • Slope, b = r(Sy/Sx)

Calculating slope, b :

  • b = 0.81(177.6 / 14.8) = 9.72

<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :

696 = 9.72(75.8) + c

696 = 736.776 + c

c = 696 - 736.776

c = - 40.776

Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

A theater is selling tickets for a performance. Mr. Smith purchased 8 senior tickets and 5 child tickets for $136 for his friend
ICE Princess25 [194]

Answer:

The price of a senior ticket is $12.

Step-by-step explanation:

Given:

Mr. Smith purchased 8 senior tickets and 5 child tickets for $136. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96.

Now, to get what is the price of a senior ticket.

Let the senior ticket be x and the child ticket be y:

So, according to question

8x+5y=136.........(1)

4x+6y=96...........(2)

Now, we have system of equations:

Multiplying the equation (2) by -2 we get:

-8x-12y=-192.......(3)

Now, adding the equation (3) and (1) the variables and the numbers:

-8x-12y+8x+5y=-192+136

-7y=-56

Dividing both sides by -7 we get:

y=8

Putting the value of y in equation (2) we get:

4x+6(8)=96

4x+48=96

On solving the equation we get:

x=12.

Therefore, the price of a senior ticket is $12.

Plz hurry, brainliest and lots of points plz explain answer and only answer if you are actually gonna do it.
Citrus2011 [14]

Answer and Step-by-step explanation:

1st box:

0, -3

2nd box

-2, -9/4

3rd box:

2, -3/2

4th box:

4, 0

Btw 0, -2, 2, 4 are in the x-coordinate column if you didn’t know, and 1, -9/4, -3/2 are in the y-coordinate column

Basically to solve if you plug in 0 into x, so basically it’s 3(0)-4y=12, which you simplify gives you 0-4y=12, subtract 0 from 12 which is 12 and then do 12 divided by -4 and then you get y = -3 and that’s how you get the box answer

Idk how to the rest srry lol!
