What speed is a car traveling if it goes 240 miles in 4 hours? 60 miles per hour 40 miles per hour 80 miles per hour 30 miles

60 miles per hour

Step-by-step explanation:

Use speed = distance / time

Speed = 240 / 4

240 / 4 = 60

Speed = 60

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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
