A movie screen has an area of 162 square meters and a perimeter of 54 meters. What are the dimensions of the screen?

____meters by ___ meters

Answers

Answer 1

Answer:

18 meters by 9 meters (or 9 meters by 18 meters)

Step-by-step explanation:

lets say the dimensions are x and y. we have x*y=162, and 2x+2y=54. from the second equation we have x+y=27 so y=27-x. plug this into the first equation to get x(27-x)=162 or -x^2 + 27x = 162. x^2 - 27x + 162 = 0. simplify to get (x-18)(x-9)=0. so x=18 or x=9. when x=18, y=9, when x=9, y=18 so the dimensions are 18 by 9 meters

Answer:

4/5

Step-by-step explanation:

Sin = Opposite / Hypotenuse

Note that hypotenuse = longest side

We want to find sinФ

The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10

So sinФ would equal 8/10 which can be simplified to 4/5

Which ordered pair is a solution to the line whose equation is 2y=-3x-2
A.(2, -3) C. (2, -4)
B. (-3, 2) D. (-4, 2)

Answers

Answer:

The solution would be C. (2, -4)

Step-by-step explanation:  Equation: 2y = -3x - 2

1. (2, -3)

  2(-3) = -3(2) - 2

  -6 = -6 - 2

  -6 = -8   (Not a solution)

2. (-3, 2)

   2(2) = -3(-3) - 2

   4 = 9 - 2

   4 = 7   (Not a solution)

3. (2, -4)

   2(-4) = -3(2) - 2

   -8 = -6 - 2

   -8 = -8   (Solution)

4. (-4, 2)

   2(2) = -4(-4) - 2

   4 = 12 - 2

   4 = 10   (Not a solution)

A sale of wedding gowns is marked at £168, which includes a reduction of 25%. What was the pre-sale price?

ASAP NOW!

Answers

The pre-sale price of the wedding gown is £224.

A reduction decreases the price of an item. As a result of the reduction, the wedding gown would be sold cheaper. The wedding gown would cost  pay 75%(100 - 25%) of the pre-sale price.

This equation can be used to determine the pre-sale price of the wedding gown:  discounted price / 75%

£168  / 0.75 = $224

If 1=3

Then, 6=?
[tex] \: \: \: [/tex]

Answers

Answer:

6 = 3

If u write 1 in word then u will write one and if you count the letter it will give u 3 .

Similarly if u write the number 2,3,4,5 in word and count the number you will get 3,5,4,4 respectively .

So ,If u write 6 in a word you will write six and on counting the letter you will get 3 .

Hence ,

6 = 3

which one? A, B, C or D?​

Answers

Step-by-step explanation:

you can't find that out ?

either simplify the expressions and then insert the values for x, or simply insert the values for x and see.

6 - 5x < 27 + 5x < x + 35

6 < 27 + 10x < 6x + 35

-21 < 10x < 6x + 8

it is then

-21 < 10x

-2.1 < x

and

10x < 6x + 8

4x < 8

x < 2

-2.1 < x < 2

therefore, B is the right answer.

-2, -1, 0, 1

-3 would be too small, and 2 is blocked by the right "<" sign.
