16 inches

Step-by-step explanation:

You can separate the screen with a diagonal into 2 right triangles.

The diagonal (hypotenuse) is 19. The base is 10. We need to find the width.

We can apply the pythagorean theorem to this. a^2+b^2=c^2

10^2+b^2=19^2

100+b^2=361

b^2=261

b=16, rounded to the nearest inch.

Therefore, the width of the screen is 16 inches.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
