HELP ME PLZZ I NEED HELP WITH THIS 50 POINTS!! Mr. Hamilton decorates his U. S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long.

Each president's picture is 6 inches wide.

(THE FIRST PICTURE WOULD GO HERE)

If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?

8 pictures

Step-by-step explanation:

Given

Step-by-step explanation:

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

Convert fraction to decimal

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

Convert feet to inches

Hence, 8 pictures can fit the wall

step-by-step explanation:

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
