Answer:

Step-by-step explanation:

To determine the number of discs, divide the area of the metal sheet by the area of the discs

The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet

Area of a rectangle = length x breadth

56 x 33 = 1848 cm^2

The disc is in the shape of a circle.

area of a circle = πr²

π = 3.14

r = radius

3.14 x 7² = 153.86 cm²

Number of discs = 1848 /153.86 = 12

As given;

2.52x10^7 people are living in <span>4.05x10^5 km^2 area. then for 1km^2, the number of people can be calculated as:
people in 1km^2 = (2.52x10^7) / (</span><span>4.05x10^5)
=0.62x10^2
or
=6.2x10^1</span>

Graph the linear inequality. 3x-y<6

Sphinxa [80]

Answer:

Step-by-step explanation:

3 x - y < 6

dividing whole equation by 6 equation comes out to be

$\frac{3x}{6}-\frac{y}{6}$

$\frac{x}{2}+\frac{y}{-6}$

from the above equation we can clearly see that the x and y co-ordinate

x co-ordinate will be (2,0) where y coordinate will be(0,-6)

and the plot is given in the attachment given below.

where as the shaded portion gives the desired region.
