Answer:
34 days 4 hours and 40 minutes
Step-by-step explanation:
First convert 3,962km to miles.
There are 1.609km in 1 mile so:
3,962km/1.609km = 2461.87 miles ≈ 2,462mi
If your walking speed is 3mph then divide the distance by 3.
2462/3 = 820.67hours.
Let's figure out the number of days, hours, minutes.
820.67hr/24 = 34.1944 days since we have a fraction of a day, let's figure out hours.
.1944 x 24 = 4.6666 So 4 hours and some minutes, let's figure out the minutes.
.66666 x 60 = 40
At 3mph it will take you 34 days 4 hours and 40 minutes to walk from New York to Los Angeles if you take no breaks and don't sleep.

Ms. Watts is a famous motivational speaker. She travels across the country by jet and gives an average of ten presentations a week
She gives her speeches in auditoriums that are always full and hold an average of 1000 people each. She charges $40 per person
at each of these speeches. Her average expenses for each presentation, including renting the auditorium, are about $15,000. The
cost of meals, motels, jet travel, and support personnel total $75,000 per week. How many weeks will Ms Watts need to travel if she
wants to earn $1,400,000 per year?
Answers
Answer:
5 weeks
Step-by-step explanation:
We are told that the auditorium holds an average of 1000 people each.
And that she charges $40 each.
Thus;
Total income for each speech is;
1000 × 40 = $40000
Since she gives an average of 10 presentations each week.
Total income per week = 10 × 40000 = $400,000
Now,the expenses she makes for each speech weekly is;
Renting auditorium = $15000
Motel, jet expenses, support personnel = $75000
Thus,
Total expenses per week = 15000 + 75000 = $90000
Now, total profit per week is;
P_weekly = Total income per week - Total expenses per week
P_weekly = $400000 - $90000
P_weekly = $310000
There are 52 weeks in a year, thus, profit in a year is;
P_yearly = 52 × 310000 = $16120000
Now, we want to find out how long it took her to make $1,400,000 a year.
We know that;
$16120000 was achieved in 52 weeks
Thus;$1,400,000 will be achieved in;
(1400000 × 52)/16120000 = 4.52 weeks approximately 5 weeks.

A box is formed by cutting squares from the four corners of a sheet of paper and folding up the sides.
Suppose the paper is 7"-wide by 9"-long.
a. Estimate the maximum volume for this box?
b. What cutout length produces the maximum volume?
Answers
Answer:
B
Step-by-step explanation:
To answer this question it is necessary to find the volume of the box as a function of "x", and apply the concepts of a maximum of a function.
The solution is:
a) V (max) = 36.6 in³
b) x = 1.3 in
The volume of a cube is:
V(c) = w×L×h ( in³)
In this case, cutting the length "x" from each side, means:
wide of the box ( w - 2×x ) equal to ( 7 - 2×x )
Length of the box ( L - 2×x ) equal to ( 9 - 2×x )
The height is x
Then the volume of the box, as a function of x is:
V(x) = ( 7 - 2×x ) × ( 9 -2×x ) × x
V(x) = ( 63 - 14×x - 18×x + 4×x²)×x
V(x) = 4×x³ - 32×x² + 63×x
Tacking derivatives, on both sides of the equation
V´(x) = 12×x² - 64 ×x + 63
If V´(x) = 0 then 12×x² - 64 ×x + 63 = 0
This expression is a second-degree equation, solving for x
x₁,₂ = [ 64 ± √ (64)² - 4×12*63
x₁ = ( 64 + 32.74 )/ 24
x₁ = 4.03 this value will bring us an unfeasible solution, since it is not possible to cut 2×4 in from a piece of paper of 7 in ( therefore we dismiss that value)
x₂ = ( 64 - 32.74)/24
x₂ = 1.30 in
The maximum volume of the box is:
V(max) = ( 7 - 2.60) × ( 9 - 2.60)×1.3
V(max) = 4.4 × 6.4 × 1.3
V(max) = 36.60 in³
To chek for maximum value of V when x = 1.3
we find the second derivative of V V´´, and substitute the value of x = 1.3, if the relation is smaller than 0, we have a maximum value of V
V´´(x) = 24×x - 64 for x = 1.3
V´´(x) = 24× 1.3 - 64 ⇒ V´´(x) < 0
Then the value x = 1.3 will bring maximum value for V

The 7 work days is represented by a linear equation
The expression that represents her gross pay each day is 5h + 8
What are linear equations?Linear equations are equations that have constant rates
How to determine the linear equationThe earning at the end of 7 work days is represented as:
35h + 56
To calculate the gross pay, each day:
We divided the total earnings by 7
So, we have:
[tex]Gross =\frac{35h + 56}{7}[/tex]
Evaluate the quotient
[tex]Gross =5h + 8[/tex]

What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The original price of the coat = $50
Discount = 40%
Now,
The final cost.
= (100 - 40)% of 50
= 60% x 50
= 60/100 x 50
= $30
Thus,
The final cost is $30.
