y = 25x + 128.8

Step-by-step explanation:

y = total cost

x = amount of days the car was rented

25 represents the daily charge for the fee and the insurance (15+10=25)

128.8 represent the cost for miles driven by Jerry

This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)

644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes

Answers

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?

Answers

Answer:

625

Step-by-step explanation:

Let two number be x and (50-x).

The product of numbers be x(50-x).

P = 50x-x²

For maximizing the product,

[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]

So, the maximum product, P = 50(25)-(25)²

P = 625

Hence, the maximum value of the product of these two numbers is 625.
