Area of the board = 3.6 * 1.8 = 6.48 m^2 = 6.48 * 100 * 100

= 648 * 10,000 = 64,800 cm^2

Area of 1 photo = 36 cm^2

So number of pictures which will fit on the screen

= 64,800 / 36

= 1,800 answer

Since the length and width of the pictures are given in cm, let's convert all lengths to cm.

Remember that 1 m = 100 cm

3.6 m = 360 cm

1.8 m = 180 cm

The area of a rectangle is A = LW. The area of the board is

A = LW = 360 cm * 180 cm = 64,800 cm^2

The area of each picture is 6 cm * 6 cm = 36 cm^2

To see how many pictures fit in the board, we divide the area of the board by the area of one picture.

(64,800 cm^2)/(36 cm^2) = 1,800

Answer: 1,800 pictures

The equation t^3=a^2 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A
ankoles [38]

Answer:

     2√2

Step-by-step explanation:

We can find the relationship of interest by solving the given equation for A, the mean distance.

<h3>Solve for A</h3>

  T^3=A^2\\\\A=\sqrt{T^3}=T\sqrt{T}\qquad\text{take the square root}

<h3>Substitute values</h3>

The mean distance of planet X is found in terms of its period to be ...

  D_x=T_x\sqrt{T_x}

The mean distance of planet Y can be found using the given relation ...

  T_y=2T_x\\\\D_y=T_y\sqrt{T_y}=2T_x\sqrt{2T_x}=(2\sqrt{2})T_x\sqrt{T_x}\\\\D_y=2\sqrt{2}\cdot D_x

The mean distance of planet Y is increased from that of planet X by the factor ...
