The time the airplane will arrive at its destination is; 12:30 pm

The relationship between distance, time and speed is;

Speed = Distance/time

Now, we are given;

Distance = 1375 miles

Speed = 550 miles per hour

Thus;

Time = Distance/Speed

Time taken = 1375/550

Time taken = 2.5 hours

Thus, if he leaves by 10 am, then the time to arrive is;

10 am + 2.5 hours = 12:30 pm

The equation of the polynomial on the graph is P(x) = x^2(x - 2)(x + 2)

Expressions are mathematical statements that are represented by variables, coefficients and operators

The graph represents the given parameter

On the graph, we have the following points

The multiplicities at these points are

Using the above as a guide, the equation of the polynomial is

P(x) = (x - x value)^Multiplicity

So, we have

P(x) = (x - 2)^1 * (x + 2)^1 * (x - 0)^2

The above equation becomes

P(x) = (x - 2) * (x + 2) * x^2

Evaluate

P(x) = x^2(x - 2)(x + 2)

Hence, the equation of the polynomial on the graph is P(x) = x^2(x - 2)(x + 2)

The probability that every person gets his or her hat back is 1/n!

If each possibility in a sample space S has the same chance of happening, then all of the outcomes are equally likely. The following experiment shows how easy it is to compute the probability of a single result or an event if all outcomes in a sample space S are equally likely.

Think about the sample space for all hat assignments.

This has n! components (n hat picks for the first person, then n - 1 for the second, etc.),

with each occurrence having a chance of 1/n and being equally likely. Calculation is the issue.

We get the repeated addition as ( - 4 ) + ( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ).

We are given a multiplication expression:

( + 7 ) ( - 4)

We need to write this expression as a repeated addition

Repeated addition means when we add the same digits many times that is repeatedly.

For example: 3 + 3 + 3 + 3 or 8 + 8 + 8 + 8 or 5 + 5 + 5 +5 etc.

Here, we can see that -4 is multiplied by 7

It means that - 4 will be added 7 times repeatedly to form the expression

So, we get that:

= ( - 4 ) + ( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 )

Therefore, we get the repeated addition as ( - 4 ) + ( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ) +( - 4 ).

The hexadecimal representation for the given question is 1. 0xAD 2. 0x27 and the decimal representation of the given question is 1. 10001110 2. 01011100

The hexadecimal numeral system, usually known as base 16 or just "hex," is a positional numeral system used in mathematics and computing that uses the radix (base) of 16 to represent integers. Hexadecimal uses 16 different symbols as opposed to the decimal system's 10 symbols, with the most common being "0"-"9 to represent values 0 to 9 and "A"-"F" (or alternatively "a"-"f") to represent values 10 to 15. Hexadecimal numbers are frequently used by software engineers and system designers because they offer a human-friendly representation of binary-coded data. For example, an 8-bit byte might have values ranging from 00000000 to 11111111 in binary form, which can be succinctly represented as 00 to FF in hexadecimal. Each hexadecimal digit represents four bits (binary digits), often known as a nibble (or nybble).

If, we invested $2,800 at a 6% annual interest rate. We will have $2972.70 in 1 year and $3063 in 1.5 year of time.

In the fields of finance and economics, interest is defined as the payment of a sum over and above the principal amount (the amount borrowed) at a set rate by a borrower or deposit-taking financial institution to a lender or depositor. It is different from a fee that the borrower may pay to the lender or another entity. It also differs from a dividend, which is money given to shareholders (owners) by a company from its profit or reserve, but not at a set rate predetermined beforehand, but rather on a pro rata basis as a portion of the rewards received by risk-taking businesspeople when revenue is earned that exceeds all costs.

Calculations:

1 drink(s) within a 4 hour time span, regardless of height and weight, can get you a BAC of .01%.

Blood Alcohol Content (BAC) is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume.

Here, the BAC = 0.1%

Time span = 4 hours

We know,

BAC is a measure of alcohol in the blood as a percentage

Alcohol leaves the body at an average rate of 0.015 g/100mL/hour

The gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11) is y = 5x + 6

Gradient intercept form Or slope incept form of a linear equation is given by

y = mx + c

where m is the gradient or slope of the equation  and c is the constant

As we are aware that the line passes through a point whose coordinates are (1, 11)

By putting the value of gradient/ slope,  x coordinate in place of x in equation and  y coordinate in place of y in equation we get

11 = 5 (1) +c

11= 5 + c

11-5 = c

6 = c

now, substituting the value of c in the Gradient/ slope intercept form

y = 5x + 6

The area swept by the wiper is 860.75 square inches, as calculated by the formula of area of a sector.

Given:

To find: Area swept by the wiper.

Finding:

As area of the sector = [tex]\frac{1}{2}r^{2}\theta[/tex],

Area swept by the wiper will be given by: (Area of the sector made by the top end of the windshield) - (Area of the sector made by the bottom end of the windshield)

=> Area swept by the wiper = [tex]\frac{1}{2}(30)^{2}\frac{3\pi}{4} - \frac{1}{2}(13)^{2}\frac{3\pi}{4}[/tex]

In order to cover the entire land area of United States with dollar bills, it would cost 9 × 10¹⁴ dollars.

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Conversion:

1 mile = 160934 cm

Length of contiguous land = 160934 × 3000 miles = 482,802,000 cm.

Width of contiguous land = 160934 × 1000 miles = 160,934,000 cm.

Mathematically, the area of a rectangle can be calculated by using this formula;

Area of rectangle = length × width

Area of contiguous land = 482,802,000 × 160,934,000

Area of contiguous land = 77,699,257,068,000,000 cm²

Next, we would determine the area of Alaska:

Area of Alaska = 1/5 × 77,699,257,068,000,000

Area of Alaska = 15,539,851,413,600,000 cm²

Total area = Area of Alaska + Area of contiguous land

Total area = 15,539,851,413,600,000 + 77,699,257,068,000,000

Total area = 93,239,108,481,600,000 cm²

Also, the area of a dollar bill is given by:

Area of dollar bill = 6.5 × 15.5

Area of dollar bill = 100.75 cm²

Now, we can determine the cost:

Cost = Total area/Area of dollar bill

Cost = 93,239,108,481,600,000/100.75

Cost = 9 × 10¹⁴ dollars.

The amount of snowfall in February 2015 was 36.4 inches and the amount of snowfall in February 2020 was 17.9 inches

From the question, we are to determine the amount of snowfall in February 2015 and in February 2020

Let the amount of snowfall in February 2015 be x

and the amount of snowfall in February 2020 by y

From the given information,

"The snowfall in February 2015 was 0.6 inch more than twice the snowfall in February 2020"

That is,

x = 0.6 + 2y

Also, from the information

"The snowfall in February 2015 was also 8.35 inches fewer than 2.5 times the snowfall in February 2020"

x = 2.5y - 8.35

Now,

Solve the system of equations simultaneously

x = 0.6 + 2y             -------- (1)

x = 2.5y - 8.35        -------- (2)

Equate equations (1) and (2)

0.6 + 2y = 2.5y - 8.35

0.6 + 8.35 = 2.5y - 2y

8.95 = 0.5y

y = 8.95/0.5

y = 17.9

Substitute the value of y into equation (1)

x = 0.6 + 2y

x = 0.6 + 2(17.9)

x = 0.6 + 35.8

x = 36.4

Hence, the amount of snowfall in February 2015 was 36.4 inches and the amount of snowfall in February 2020 was 17.9 inches
