Sergio claims that StartFraction 20 Over 20 EndFraction = 1 percent. Which statement is true regarding his claim? Sergio is correct because StartFraction 20 Over 20 EndFraction = 1.
Sergio is correct because 20 out of 20 represents 1 whole.
Sergio is incorrect because StartFraction 20 Over 20 EndFraction = StartFraction 100 Over 100 EndFraction
Sergio is incorrect because the ratio simplifies to 0.

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

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

the answer is 11.2 (i know i’m late)

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
