Grandma Susette is making a quilt. If the area of the quilt is 24 3/5 square feet and one side has a length of
4 1/10,what is the width of the quilt?

width = 6 ft

Step-by-step explanation:

let  A = 24 3/5 = (24*5 +3)/5 = 123/5 ft^2 the area

l = 4 1/10 = (4*10 + 1)/10 = 41/10 ft the length

w = the width, w>0

since the area = length*width we have:

l*w = A

(41/10)*w = 123/5

by solving we find:

w = 6 ft

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

246
