You are running a fuel economy study. One of the cars you find is blue. It can travel 40 1/2 miles on 1 1/4

gallons of gasoline. Another car is red, it can travel 28 4/5

miles on 4/5

gallon of gasoline. What is the unit rate for miles per gallon for each car ? Which car could travel the greater distance on 1 gallon of gasoline

the unit rate for miles per gallon for each car? Which car could travel the greater distance on

1 gallon of gasoline?

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

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
