If myron receives 10 votes from his class of 25 students, what percentage does he receive?

Step-by-step explanation:

One way to solve this equation is by first creating a fraction. If 25 is the total number of students then it will be the denominator or bottom number of your fraction. 10 will be the numerator or top number. Now you have the fraction 10/25. This fraction can be reduced to the fraction 2/5 by dividing both numbers by 5. Next convert the fraction 2/5 to a decimal by dividing 2 by 5. You should have the fraction 0.4. To turn this decimal into a percentage multiply it by 100. You will end up with number 40 which is your final answer. So Myron received 40% of the votes.

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
