A monitor with dimension ratio of 16:9 is playing a video imagine with a dimension ratio 3:4 at its fullest size which left a pillar boxed imagine what percent of the screen area is occupied the imagine

  75%

Step-by-step explanation:

The image is 4 : 3 = 12 : 9. It is displayed on a screen that is 16 : 9, so it occupies 12/16 = 3/4 of the screen.

  75% of the screen area is occupied

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

x-3y=4
