the top and bottom ends of a windshield wiper blade are 30 inches and 13 inches, respectively, from the pivot point. while in operation, the wiper sweeps through 135°.
Answers
The area swept by the wiper is 860.75 square inches, as calculated by the formula of area of a sector.
What is a sector and its area?A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.Area of a sector = [tex]\frac{1}{2}r^{2}\theta[/tex] (where the angle is in radians)Given:
Top end of windshield = 30 inchesBottom end of windshield = 13 inchesAngle made = 135 degrees = 3π/4 radiansTo 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]
=> Area = [tex]\frac{1}{2}\frac{3\pi}{4}(900 - 169)[/tex]
=> Area = [tex]\frac{1}{2}\frac{3\pi}{4}(731)[/tex] ≈ 860.75 square inches
Hence, the area swept by the wiper is 860.75 square inches, as calculated by the formula of area of a sector.

find the gradient-intercept form of the equation of the line which has a gradient of 5 and passes through the point (1, 11)
Answers
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
Hence, 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

the hats of n persons are thrown into a box. the persons then pick up their hats at random (i.e., so that every assignment of the hats to the persons is equally likely). what is the probability that (a) every person gets his or her hat back?
Answers
The probability that every person gets his or her hat back is 1/n!
What are equally likely function?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.),

SNOWFALL In February 2015, South Bend, Indiana , saw one of its snowiest Februarys on record. The snowfall in February 2015 was 0.6 inch more than twice the snowfall in February 2020. The snowfall in February 2015 was also 8.35 inches fewer than 2.5 times the snowfall in February 2020. Write and solve an equation to find the amount of snowfall in February 2015 and in February 2020 .
Answers
The amount of snowfall in February 2015 was 36.4 inches and the amount of snowfall in February 2020 was 17.9 inches
Solving system of equationsFrom 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

Random groups of 30 teachers were asked the starting annual salary for their
first teaching job. The sampling variability was low. If the average salary of
several of the groups was close to $51,000, which of these is least likely to be
the average salary of another one of the groups?
Answers
If the average salary of several of the groups was close to $51,000 then least likely to be the average salary of another one of the groups are equal to $41,000.
Random groups of teachers are = 30
If the average salary of several of the groups was close to equal to = $51,000
The mean, or average, salary is the amount derived by adding two or more salary values and dividing the sum by the number of values.
So we can write,
The average wage is known to be close to $41,000
$41,000 < $51,000
Therefore,
The average salary of another one of the groups are equal to $41,000.

In order to cover the entire land area of United States with dollar bills, it would cost 9 × 10¹⁴ dollars.
What is a conversion factor?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.

Answers
The time the airplane will arrive at its destination is; 12:30 pm
What is the relationship between distance and time?
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

What do you mean by the term hexadecimal?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).
