George's page contains twice as many typed words as bills page and bills page contains 50 fewer words than charlie's page. if each person can type 60 words per minute, after one minute, the difference between twice the number of words on bills page and the number of words on charlie's page is 210. how many words did bills page contain initially?

260

Step-by-step explanation:

Rearrange the equations::

2b + 0 - g = 0

b - c + 0 = -50

2b - c + 0 = 210

Solve the system be any method you know to get:

: b = 260 (# of words on Bill's page)

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

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
