If he eats 2 carrot he left with 4 carrot.
If he eats 3 carrot he left with 3 carrot.
If he eats 4 carrot he left with 2 carrot.
Step-by-step explanation:
Consider the provided information,
Max has 6 carrots. He eats more than 1 carrot. He has more than 1 carrot left.
He eats more than 1 carrot that means he can eat 2, 3, or 4 carrots.
Note. He can't eat 5 carrots because 6-5 = 1 which is not more than 1.
If he eats 2 carrot:
6-2=4
If he eats 2 carrot he left with 4 carrot.
If he eats 3 carrot:
6-3=3
If he eats 3 carrot he left with 3 carrot.
If he eats 4 carrot:
6-4=2
If he eats 4 carrot he left with 2 carrot

The markup indicates the difference between the selling price and the item's cost to the business.In general, a corporation generates more money the higher the markup.The retail price of a product less its cost is known as markup, although the margin percentage is determined in a different way.
Calculate percentage on markup based on cost ?
The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.Selling price = cost + markup
= 1.17+0.78
=1.96
percentage markup based on cost = markup/cost*100
0.78/1.17*100
= 66.66
percentage on selling = percentage on markup cost/100+percentage on cost
= 66.66/100%+66.66

The area of the Great Lakes is 988 square miles.
According to the question,
We have the following information:
The area of the Great Lakes is about 9.5 x 104 square miles.
Now, the area of the Great Lakes can simply be found by multiplying the given two numbers.
Now, in the multiplication involving numbers with decimal points, we know that the numbers are multiplied first as if there is no decimal point but in the result obtained we put the decimal point to exactly counting the digits where the decimal point was placed in the input. We move the decimal point to the left hand side according to the number of digits.
In this case, point is after 1 digit.

2. What is a relation? What makes it different from a function?
3. How can you determine the domain and range from a function?
4. What is Slope and how is it determined from a graph?
5. How do you determine the intercepts from an equation and graph.
6. Provide an example of the different forms linear equations and functions can be written.
Answers
Answer:
1 These 5 main features are the title, scale, points, labels, and line.
2. Relations are a group of ordered pairs from one set of objects to another set of objects while functions are relations that connect one set of inputs to another set of outputs. So all functions are relations while all relations are not functions.
3. To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
4. The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. In other words, Pick two points on the line and determine their coordinates.
5. To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'. To find the y-intercept, plug 0 in for 'x' and solve for 'y'.
6. An example of a linear equation is: 2x + y - 3 = 0. It can be written in the standard form, the slope-intercept form, and the point-slope form. Here we mainly used the slope-intercept form y=mx+c y = m x + c . To write linear equations find the slope and y-intercept and then substitute these values into the equation.

If Sarah were to paint her living room alone, it would take 5 hours. Her sister Rachel could do the job in 8 hours. How long would it take them working together?
Answers
It takes a specific amount of time (T) to finish a particular task (W). The rate of work is the quantity of units of work completed per unit of time (R). Work (W) = Rate (R) Time, thus (T).
They spent 40/13 hours together painting her living room.
What is the relationship between time and work?Time = 1 divided by the rate of work. If a task is completed across x days, then the amount of work completed in a single day is equal to 1/x. Total Work Done = Days * Productivity. Time and effectiveness are inversely related to one another.Time and work concerns concern the simultaneous performance of a person or a group's productivity and the amount of time it takes for them to finish a task. Work is the energy expended to complete a task or produce a deliverable.It takes a specific amount of time (T) to finish a particular task (W). The rate of work is the quantity of units of work completed per unit of time (R). Work (W) = Rate (R) Time, thus (T)sarah does the 1/5 of the job per hour.
Rachel does the 1/8 of the job per hour.
Together, they do 1/5 + 1/8 of the job per hour.
= 13/40 of the job each hour
The inverse of job/hour = hours per job
---> 40/13 hours to do it together.
For a shortcut:

The probability that fewer than three of the selected consumers believe that cash will be obsolete in the next 20 years is 0.538.
How to calculate the probability?The following can be deduced:
p = 40.3% = 0.403

n = 6
Therefore X follows the Binomial (6 , 0.403)

Julia's text messaging plan charges 15 cents for each messages over 650 in addition to a $15 base charges. If she owes $49.50 for text messaging in the month of May, how many test messages did she send for that month?
Answers
Julia sent 880 text messages in the moth of May .
In the question ,
it is given that
Cost for first 650 messages = $15
additional text message charge = $0.15
Amount owed by Julia for the month of May = $49.50
Let the number of Additional messages be x.
So, according to the question
15 + 0.15x = 49.50
0.15x = 49.50 - 15
0.15x = 34.5
x = 34.5/0.15
x = 230
number of extra messages = 230
total messages = first 650 messages + extra messages

distributed across each month, after how many months will the company recover its
investment in Program X?
Answers
The business will need 10.5 months to make back the money it invested in Program X.
How do you determine monthly costs?Actual or anticipated costs for each monthly expense are needed to calculate the average monthly expenses.
How do you figure out the return on investment?By dividing an investment's net profit (or loss) by its initial cost or outlay, we can determine the return on investment.
Program X costs $35,000 per year, but is anticipated to save $40,000 for Company C in the first year.
Considering that the savings and the cost are equal over the course of each month
So, 40000/35000 = 0.875
No. of months to recover = 0.875 × 12
= 10.5 months

To which axis is the graph of the equation given symmetrical about?It follows from the task content that the axis about which the given graph is symmetrical be determined as follows.
Since it follows that for a function to be symmetric about the y-axis;
f(-x) = f(x).
Therefore, we have;
f(-x) = (-x)² + 20.
f(-x) = x² + 20 = f(x).
Hence, the graph is symmetrical about the y-axis.
Also; Since; f(-x) = x² + 20 ≠ - f(x).
