Final answer:
To find the total number of burgers sold by the fast food restaurant, calculate the burgers sold without cheese using the ratio provided and then find the total by adding burgers with cheese and without cheese.
Explanation:
To find out how many burgers the fast food restaurant sold in total, we first need to determine the number of burgers sold without cheese. Since the ratio of burgers sold with cheese to without cheese is 7:3, we can calculate that for every 7 burgers sold with cheese, 3 were sold without cheese. Therefore, 35 burgers with cheese corresponds to 35 / 7 * 3 = 15 burgers without cheese. Hence, the total number of burgers sold is 35 (with cheese) + 15 (without cheese) = 50 burgers.

two cousin one is five years older. the sum of there age is 37. how old are they
Subtract the difference from the total, then divide by 2, that would be the age of the youngest, then add the difference to that for the age of the oldest.
37 - 5 = 32
32 / 2 = 16
The youngest is 16.
16 + 5 = 21
The oldest is 21.
The ages are 16 and 21.
Timmy writes the equation f(x) = 1/4x – 1. He then doubles both of the terms on the right side to create the equation g(x) = 1/2x – 2. How does the graph of g(x) compare to the graph of f(x)? The line of g(x) is steeper and has a higher y-intercept. The line of g(x) is less steep and has a lower y-intercept. The line of g(x) is steeper and has a lower y-intercept. The line of g(x) is less steep and has a higher y-intercept.
Remark
The best way to answer something like this is to actually graph both equations. I have done that for you below.
Red Line: f(x) = 1/4x - 1
Blue Line: g(x) = 1/2x - 2
Now look at the answers.
A: The first one is incorrect. You don't need the graph to tell you that. The larger the number in front of the x, the steeper the line. Put another way, the larger the slope, the steeper the line. The y intercept is lower however.
B is wrong. g(x) is steeper, but the y intercept is lower not higher than f(x) [Negatives do strange things].
C:The g(x) is steeper (we've said that a couple of times), and it has a lower y intercept.
D is correct.
E is just wrong. Both parts are incorrect.
Shamika is making cakes in the same shape, but different sizes, to sell at a school bake sale. She says that the perimeter for each cake is porportional to the length of one side. What shape are her cakes?
Answer: Square.
Shamika is making cakes that are of the same shape but they differ in sizes. According to her, the perimeter of one cake is proportional to one the side lengths.
If we consider a few basic shapes, we can think of a circle, a triangle, a square.
For circle, it cannot be true because it has no sides.
For this to be true for a triangle, the triangle must be equilateral.
However, a square is such a shape which has equal length of all the sides. So for squares of different sizes, the perimeter of each cake would be proportional to one of its side.
Perimeter of square = x + x + x + x = 4x
Therefore 4x/x = 4
A square of perimeter 4 will have a proportion of 1:4 from its length to perimeter.
51 is the product of diego’s score and 3
Translate into an equation
Answer:
3d = 51 is the desired equation; its solution is d = 17.
Step-by-step explanation:
Let d represent Diego's score. Then 3d = 51, or d = 17.
"51 is the product of Diego's score and 3" is written as 51=3x. We know this because "is" means "=", and "the product of" means multiplication. Since "Diego's score" is unknown, it would be a number x (multiplied by 3 would make it 3x). The answer to this is 17, because 51/3=17. :)
The table shows the rates at which Ajay and Tory are biking along the same trail.
Person: Rate:
Ajay: 200
Tory: 250
a. Suppose Ajay began the trail 325 meters ahead of Tory. Write a system of equations to represent the distance y each person will travel after any number of mimutes x.
Answer:
For Ajay , [tex]y=200x+325[/tex]
For Tory, [tex]y=250x[/tex]
Step-by-step explanation:
Formula to find distance = rate × time
Rate of Ajay = 200
Rate of Tory = 250
In x minutes
Distance travelled by Ajay = 200 ×x = 200x
Distance travelled by Tory = 250 ×x = 250x
But Ajay was already ahead by 350 meters.
So for Ajay, the distance y traveled in x minutes
[tex]y=200x+375[/tex]
For Tory
[tex]y=250x[/tex]
Answer:
The rates are:
Ajay : 200
Tory : 250
I assume those are in meters per minute.
Now, we suppose that Ajay began the trail 325 meters ahead, so if we put the zero in Tory position, we got:
Ajay position = 325 meters + 200*x meters
Tory position = 250*x meters
Where x is the number of minutes after they started to bike.
From this, we can compare their positions, and see in which minute x Tory position and Ajay position are the same.
325 + 200x = 250x
325 = 250x - 200x = 50x
x = 325/50 = 6.5 minutes.
So before of x = 6.5 minutes, Ajay is ahead. After x =6,5 minutes, Tory is ahead.
which values are possible rational roots of 9x3+14x2−x+18=0 according to the rational root theorem
+-1/3
+-1/8
+-3
+-1/2
According to the Rational Root Theorem, the potential rational roots of the equation 9x^3 + 14x^2 - x + 18 = 0 are ±1/3 and ±3. The values ±1/8 and ±1/2 are not valid since their denominators are not factors of the leading coefficient, which is 9.
Explanation:The possible rational roots of the polynomial equation 9x^3 + 14x^2 - x + 18 = 0 can be determined using the Rational Root Theorem. This theorem states that any rational solution, expressed in the form of a fraction p/q, where p is a factor of the constant term and q is a factor of the leading coefficient, must be among these possible roots.
The constant term in this equation is 18, and its factors are ±1, ±2, ±3, ±6, ±9, ±18. The leading coefficient is 9, with factors of ±1, ±3, ±9. According to the Rational Root Theorem, we take each factor of the constant term and divide by each factor of the leading coefficient to find the possible rational roots. Thus, the potential rational roots are ±1/1, ±1/3, ±1/9, ±2/1, ±2/3, ±2/9, ±3/1, ±3/3, ±3/9, and so forth, including their negative counterparts.
From the options provided in the question, the potential rational roots that fit the criteria set by the theorem are: ±1/3, and ±3. The other options, ±1/8, ±1/2, do not satisfy the theorem as their denominators are not factors of the leading coefficient.

hope this answers your question.
Final answer:
The variable expression for the age of Kayli's dad, in terms of Kayli's age (x), is 6x - 4, where x represents Kayli's age.
Explanation:
The question asks for a variable expression for the age of Kayli's dad, given that his age is 4 years less than 6 times Kayli's age. To create this expression, we first recognize that "6 times Kayli's age" can be represented as 6x, where x is Kayli's age. To account for "4 years less," we simply subtract 4 from this expression. Therefore, the age of Kayli's dad, in terms of Kayli's age (x), is represented by the variable expression 6x - 4.

Step-by-step explanation:
Miguel rode his bike 20 miles in 2.5 hours
Miguel rode his bike 20 miles in 2.5 hours
(1)Starting information is , In 2,5 hours Miguel traveled 20 miles
(2)Now we complete the table
In 2,5 hours distance traveled = 20 miles
So in 1 hour distance traveled = [tex]\frac{20}{2.5} =8 miles per hour[/tex]
Time 0 0.5 1 1.5 2 2.5
Distance 0 4 8 12 16 20
(3) The graph is attached below
(4) Equation y = kx
y is the distance
x is the time
Distance = k (time)
We know speed is 8 miles per hour
So k is 8
y = 8k is the final equation
(5) k is the constant of proportionality
the value of k= 8
so 8 is the constant of proportionality.
Answer:
Step-by-step explanation:
1). Miguel rode his bike 20 miles in 2.5 hours.
2). Since Miguel rode his bike with the speed = [tex]\frac{20}{2.5}=8[/tex] miles per hour
So the table will be
Time 0 0.5 1 1.5 2 2.5
Distance 0 4 8 12 16 20
3). Graph for the given equation is attached.
4). Since y = kx represents the situation then for Distance y = 4 miles in time x = 0.5 hours
4 = k(0.5)
k = [tex]\frac{4}{0.5}=8[/tex]
Therefore, equation will be y = 8x.
5). Since y = kx
⇒ k = [tex]\frac{y}{x}[/tex]
Proportionality constant k represents the speed of Migual.

A veterinarian needs to know an animal's weight in kilograms if 20 lb is about 9 kg in a dog weighs 30 lb use a ratio table to find the dogs weigh in kilograms explain your reasoning
Answer:
13.5 kgs.
Step-by-step explanation:
Here we have to find conversion factor of lbs into kg.
For this we use the given information.
Given that the weight of a dog is 20 lbs and also 9 kg.
Hence we have conversion factor as
20 lbs = 9 kg
Or 1 lb =9/20 = 0.45 kg.
Using this, we find the 30 lb converted into kg.
For 1 lb, equivalent kg = 0.45
Hence for 30 lbs equivalent kg= 30(0.45) = 13.5 kg.

Help! Geometry question.
Start with congruencies of 130°:
∠1 and 130° are vertical angles
∠2 and 130° are corresponding angles
∠5 and 130° are alternate exterior angles
m∠1 = m∠2 = m∠5 = 130°
∠7 and 130° are supplementary angles (which means their sum is 180°). So, ∠7 = 50°
Next, find congruencies of ∠7:
∠3 and ∠7 are vertical angles
∠4 and ∠7 are corresponding angles
∠6 and ∠7 are alternate exterior angles
m∠3 = m∠4 = m∠6 = m∠7 = 50°

Let's just figure out what f(1) and f(3) are and what equation to use.
f(1)
f(1) is defined by the top condition. Look at the condition carefully. -3 ≤ x ≤ 1
So the value of f(1) is
(x + 1)² -1
(1 + 1)² - 1
2² - 1
4 - 1 = 3
f(3)
f(3) is governed by the middle condition. 1 < x ≤ 3
The value of f(3) is - x + 2 = - 3 + 2 = - 1
Conclusion
f(1) > f(3)

What is one light year in seconds need it to written out in the conversion format
In one year there are 365 days of 24 hours. Each hour has 60 minutes and each minute is 60 seconds long. So, 60s/min x 60 min/hr x 24hr/day x 365 days equals 31,536,000s.
Hope this helps you with your answer. If it is incorrect, then I am sorry.
I'm going to do this in meters which will turn into km. which you can then convert into miles.
The speed of light is 2.998 * 10 ^8 meters /second
2.998*10^8m/s[3600 s/hr]*[24 hrs/day]*[365 days/year]
2.998*10^8 * 3600 * 24 * 365 = 9.45*10^15 m/year
9.45*10^15 m/year / 1000 m/km = 9.45 * 10^12 km/year
If you want miles, just divide this number by 1.6
9.45 * 10^12 / 1.6 = 5.91 * 10^12 miles / year. When you google this, the answer they give is 5.87 * 10^12 miles / yr. The difference is in where you round, the use of an approximate 1.6 and the length of a year.
max and his friend eke are comparing their ages. They figure out that if they double max's age from 3 years ago and add it to zee's current age, the sum is 26.If zeke is currently 8 years old determine how old max currently is.
Answer:
Max is currently 12 years old.
Step-by-step explanation:
Zeke's current age = 8 years
Lets take Max's current age as [tex]x[/tex] years.
Then Max's age 3 years ago = [tex]x-3[/tex]
Double Max's age 3 years ago = [tex]2*(x-3)[/tex]
Double Max's age 3 years ago + Zee's current age = 26
⇒ [tex]2*(x-3)[/tex] + [tex]8[/tex] = [tex]26[/tex]
=[tex]2*(x-3)+8=26[/tex]
=[tex]2x-6+8=26[/tex] (Simplifying the brackets)
=[tex]2x+2=26[/tex]
=[tex]2x+2-2=26-2[/tex][tex]2x=24
=[/tex][tex]x=12[/tex]
So Max's current age is 12 years.
7.5x+20y=900 models how many hours (x) and how many lawns mowed (y) Jon has to work in order to save $900. Give 3 combinations of hours worked and lawns mowed that result in $900.
Final answer:
The equation 7.5x + 20y = 900 can be solved for y by substituting different values for x to find three combinations that satisfy the equation: (0 hours, 45 lawns), (40 hours, 30 lawns), and (80 hours, 15 lawns).
Explanation:
The equation 7.5x + 20y = 900 models the relationship between the hours worked (x) and lawns mowed (y) for Jon to save up $900. To find combinations that result in $900, we can select different values for x or y and solve for the other variable.
Let x = 0 (no hours worked), then 7.5(0) + 20y = 900, which simplifies to 20y = 900. Dividing both sides by 20 gives us y = 45. So, one combination is (0 hours, 45 lawns).Let x = 40 (hours worked), then 7.5(40) + 20y = 900, which simplifies to 300 + 20y = 900. Subtracting 300 from both sides gives us 20y = 600, and dividing by 20 results in y = 30. Thus, another combination is (40 hours, 30 lawns).Let x = 80 (hours worked), then 7.5(80) + 20y = 900, which simplifies to 600 + 20y = 900. Subtracting 600 from both sides gives us 20y = 300, and dividing by 20 results in y = 15. Therefore, a third combination is (80 hours, 15 lawns).These three combinations represent different ways Jon can work hours and mow lawns to reach his goal of saving $900.
