Drinks at the fair cost 2.50$ use an equation to represent the relationship between the numbers of drinks bought ad the cost define your variable and make a table to help write the equation
Answer:
[tex]C=2.5d[/tex]
Step-by-step explanation:
Your variable is always the number of drinks that you are going to drink, and the independent clause is the cost of the drink, which is $2.5.
Drinks Cost
1 2.5
2 5
3 7.5
4 10
5 12.5
SO now you know that the cos of 3 drinks is 7.5 and that can be escalated to any number that you want just by puttin the number of drinks that are going to be bought and multiply it by the cost.

The pitch of a roof is its slope. The roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft. Find the pitch of the roof.
The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.
What is Slope?
The slope of line is a measure of its steepness.
Given that;
Vertical distance (rise) = 8 feet
Horizontal distance (running) = 15 feet
Now, To find the pitch (slope) of the roof, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Hence, The pitch (slope) of a roof is given by the formula;
Pitch = V / R
Where:
V is the rising vertical distance of an object.
H is horizontal distance an object runs through.
Hence, Substituting the given parameters into the formula, we have;
Pitch = 8/15
= 0.53
Thus, Pitch (slope) = 0.53
So, The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.

If −5e^x^2 y=x and y(−5)=0, find y′(−5) by implicit differentiation
you borrow $200 from a friend to help pay for the new laptop computer. You pay your friend $12 per week. Write and solve an inequality to find when you will owe tour friend less than $60.
You will owe your friend less than $60 if you pay them $12 per week for more than 11.67 weeks, which means you'll need to make payments for at least 12 full weeks.
Explanation:To solve the problem of when you will owe your friend less than $60, we need to set up and solve an inequality.
The amount owed after any number of weeks can be represented by the initial debt of $200 minus the total amount paid off, which is $12 times the number of weeks.
If we let x represent the number of weeks, the inequality we need to solve is 200 - 12x < 60.
To solve this inequality, we subtract 200 from both sides, getting -12x < -140.
Then, we divide both sides by -12, remembering to reverse the inequality sign because we are dividing by a negative number, which gives us x > 11.67.
Since we can't pay off part of a week, we would need to pay your friend for at least 12 full weeks to owe less than $60.
Final answer:
To find when you will owe less than $60, set up the inequality 200 - 12w < 60. After simplifying, we see that it will take just over 11.67 weeks, so you will owe less than $60 after making payments for 12 weeks.
Explanation:
To solve the problem at hand, we need to create an inequality to represent the situation where you will owe less than $60 to your friend. Let's denote the amount owed each week with w and the total amount owed with A. You start with an initial debt of $200, and each week you pay off $12. The inequality we are trying to establish is when the total amount owed will be less than $60.
The inequality will be in the form of A - 12w < 60, where A is the initial amount of $200 and w represents the number of weeks. Plugging in $200 for A, we get 200 - 12w < 60.
To solve for w, we'll perform the following steps:
Subtract $200 from both sides to isolate the variable term: -12w < -140.
Since we are dividing by a negative number, remember to flip the inequality sign: w > 140/12.
Simplify the fraction to get the minimum number of weeks: w > 11.67.
You will owe your friend less than $60 after roughly 12 weeks since fractions of a week don't apply in the context of a weekly payment schedule.

Part A: Solve –vp + 40 < 95 for v. Show your work. (4 points) Part B: Solve 8w – 3r = 45 for r. Show your work. (6 points)
Answer:
A)[tex]v>-\frac{55}{p}[/tex]
B)[tex]r=\frac{8}{3}w-15[/tex]
Step-by-step explanation:
A)
The inequality is
–vp + 40 < 95
Subtract 40 to both sides
–vp < 95 - 40
-vp< 55
Now, divide both sides by -p. Whenever, we divide by a negative number inequality sign changes
[tex]v>\frac{55}{-p}\\\\
B)
The given equation is
[tex]8w-3r=45[/tex]
Subtract 8w to both sides
[tex]-3r=45-8w[/tex]
Divide both sides by -3
[tex]r=-15+\frac{8w}{3}\\\\r=\frac{8}{3}w-15[/tex]
Answer:
Step-by-step explanation:
Part A:
The inequality is–vp + 40 < 95.
Work:
We subtract 40 to both sides = –vp < 55. Now, we divide both sides by -p. = v > 55/-p
Part B: Inequality is 8w − 3r = 45.
Work:
We Subtract 8w to both sides = 3r = 45 - 8w. Now, we divide both sides by -3 = r = -15 + 8w and then r = 8/3w - 15.

Share the advantages and disadvantages of the different methods for solving quadratic equations that you have learned. Share special techniques that you have developed along the way. For example, explain to your classmates your technique for remembering the quadratic formula (song, rhyme, rhythm, etc.) to help others remember it as well.
The factors of a quadratic equation will be (qx + r) and (sx+t). If the solutions are all integers, you may be able to quickly find q, r, s and t. The advantage of this method is that factoring can be very fast. The disadvantage is that factoring may not work; for instance, factoring will not find solutions that are not integers.
Completing the SquareCompleting the square is a multistep process. The main idea is to convert the original equation into one of the form (x + a)^2 = b, where a and b are constants. The advantage of this method are that it always works and that completing the square gives some insight into how algebra works more generally. The disadvantage is that this method is complex.
Quadratic FormulaThe quadratic formula is x = (-b +- (b*2 - 4ac)^.5))/2a. The advantages of this method are that the quadratic formula always works and is straightforward. The disadvantages are that the formula provides no insight and can become a rote technique.
GuessingSometimes, you can guess an approximate solution. Then, you can increase or decrease your guess, depending on whether the result from your first guess is too big or too small. The advantages of this method are that guessing can be very fast if you guess right, and can get an approximate answer quickly, if that is all you need. The disadvantage is that sometimes you won't be able to make a good guess .

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. "Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the fuel gauge. The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter. One copy of the Check-Out sheet will be given to the customer. Another copy will be kept with the on-site records of the vehicle. "The rented vehicle must be returned with a minimum fuel level the same as that indicated on the Check-Out sheet. A vehicle returned with a fuel level less than the approximate level indicated on the Check-Out sheet will be completely refueled with on-site pumps. The price of the fuel used to refuel the vehicle will be added to the Renter's total charge at a cost of $4.50 per gallon plus a $5.00 refueling charge." Tim is running extremely late and has just 5 minutes to return his rental car to the agency. The fuel tank in the car is half empty. It was full when he picked it up. (The car has a 12-gallon fuel tank.) He doesn't think he can get gas and get to the agency to return the car in time. Returning the car a day late will result in an extra daily rental charge of $32.00 and refueling the car on his own will cost $2.59 per gallon at the local gas station. Which of the following statements is true?
a. It would be cheaper to refuel the car and return it a day late.
b. It would be cheaper to return the car on time and pay the refueling costs.
c. It would cost about the same to return the car on time without gas or one day late with gas.
d. Tim is not responsible for refueling the car when he returns it.
