Answer:
Step-by-step explanation:
Total number on the trip is 24
Let the number of girls be x
Then the boys are x + 8
So... x + x + 8 = 24
2x + 8 = 24.......... This is the equation
2x = 24 - 8
2x = 16
x = 16/2
x = 8
Number of girls = 8
And number of boys = x + 8
Which is = 8+8 = 16
There were 8 girls and 16 boys on the trip.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Bradley and 23 of his classmates went on a trip to the aquarium.
∴ There are a total of 24 students.
There are 8 more boys than girls on the trip.
Assuming the no.of girls to be x, hence no. of boys is (x + 8).
So, x + (x + 8) = 24.
2x + 8 = 24.
2x = 16.
x = 8.
So, no. of girls on the trip is 8, and no. of boys on the trip is (8 + 8) = 16.

The width of a rectangle is 4 1/6 feet, and its area is 35 square feet. What is the perimeter of this rectangle?
Answer:
25 2/15
Step-by-step explanation:
A = length x width
width is 4 1/6
35 = 4 1/6 x length
solve for length
divide both sides by 4 1/6
35 divided by 4 1/6 or multiply 35 x 6/25 (reciprocal)
210/25
8 10/25 = 8 2/5 is the length
to find perimeter 2xlength + 2xwidth
2 x 4 1/6 + 2 x 8 2/5 = 2 x 25/6 + 2 x 42/5 = 50/6 + 84/5
convert to common denominator and add
use 30 as common denominator
250/30 + 504/30= 754/30
25 4/30 or 25 2/15
Final answer:
To find the perimeter of the rectangle, calculate the length using the given area and width. Then, apply the perimeter formula P = 2l + 2w. The perimeter is approximately 25.1 feet.
Explanation:
Calculating the Perimeter of a Rectangle
To find the perimeter of a rectangle, you need to know both the width and the length of the rectangle. The perimeter is the total distance around the rectangle, which is the sum of twice the width and twice the length: P = 2l + 2w.
The width of the rectangle is given as 4 1/6 feet. To find the length, we can use the provided area of the rectangle which is 35 square feet. The area of a rectangle is found by multiplying the length by the width: A = l × w. Let's call the length 'l'.
First, convert the width to an improper fraction: 4 1/6 = (4 × 6 + 1)/6 = 25/6 feet. Now set up the equation using the area: 35 = (25/6) × l. Solving for 'l' gives us l = (35 × 6)/25 = 210/25 = 8.4 feet.
Now that we have the length, calculate the perimeter using the equation P = 2l + 2w:
P = 2 × 8.4 + 2 × 4 1/6
P = 16.8 + 2 × 25/6
P = 16.8 + 50/6
P = 16.8 + 8.333...
P = 25.133... feet
Therefore, the perimeter of the rectangle is approximately 25.1 feet when rounded to one decimal place.

The line passing through (11,y) and (2,0)is parallel to the line joining (7,5) and (-2,2). Find y.
Answer: y = 3
Step-by-step explanation:
Two lines are said to be parallel if they have the same slope. All we need to do is to find the slope of each line . The formula for finding slope is given as :
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
For the first line
[tex]x_{1}[/tex] = 11
[tex]x_{2}[/tex] = 2
[tex]y_{1}[/tex] = y
[tex]y_{2}[/tex] = 0
substituting into the formula , we have
m = [tex]\frac{0 - y}{2 - 11}[/tex]
m = [tex]\frac{-y}{-9}[/tex]
m = [tex]\frac{y}{9}[/tex]
Also Finding the slope of the second line we have
[tex]m_{2}[/tex] = [tex]\frac{2-5}{-2 - 7}[/tex]
[tex]m_{2}[/tex] = [tex]\frac{-3}{-9}[/tex]
[tex]m_{2}[/tex] = [tex]\frac{1}{3}[/tex]
Since the two lines are parallel , we will equate their slope , that is
[tex]\frac{y}{9}[/tex] = [tex]\frac{1}{3}[/tex]
3y = 9
y = 3

in general, f−1(f(x)) = f(f−1(x)) =
Answer:
f−1(f(x)) = f(f−1(x)) = x
Step-by-step explanation:
Follow this simple example using the function f(x) = x + 2
f(x) = x + 2
NOw we find the inverse function f^(1)(x).
y = x + 2
x = y + 2
y = x - 2
f^(-1)(x) = x - 2
The inverse function is f^(-1)(x) = x - 2
Now we do the two compositions of functions:
f^(-1)(f(x)) = x + 2 - 2 = x
f(f^(-1)(x)) = x - 2 + 2 = x
Both are equal to x.
Answer: f−1(f(x)) = f(f−1(x)) = x
The expression [tex]f^{-1}(f(x)) = f(f^{-1}(x)) = x[/tex]
We are to prove the relationship;
[tex]f^{-1}(f(x)) = f(f^{-1}(x)) = ?[/tex]
To get the unknown, let f(x) = x - 2
Find its inverse:
Let y = x - 2
Replace y with x;
x = y - 2
y = x+2
Hence [tex]f^{-1}x = x+2[/tex]
Next is to get [tex]f(f^{-1}(x))[/tex]
[tex]f(f^{-1}(x))=f(x+2) = (x+2) - 2\\f(f^{-1}(x))= x\\[/tex]
We can conclude that [tex]f^{-1}(f(x)) = f(f^{-1}(x)) = x[/tex]

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is twice the measure of the first angle. The third angle is 12 more than the second.
Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.
x = first angle
y = second angle
z = third angle
x + y + z = 180
The sum of the measures of the second and third angles is twice the measure of the first angle. ----> y + z = 2x
The third angle is 12 more than the second. ----> z = y + 12
Use substitution to find each variable. Since z is already isolated/by itself, plug it into the other equation
y + z = 2x Plug in (y + 12) for z
y + (y + 12) = 2x Simplify
2y + 12 = 2x Divide 2 on both sides
y + 6 = x Isolate "y"
y = x - 6 Next you could plug this into z = y + 12, so that z has the x variable
z = y + 12
z = x - 6 + 12
z = x + 6
Now that you have y and z, you can do this:
x + y + z = 180
x + (x - 6) + (x + 6) = 180 Simplify
3x = 180 Divide 3 on both sides
x = 60 Now that you found x, plug it into the other equations to find y and z
y = x - 6
y = 60 - 6
y = 54
z = x + 6
z = 60 + 6
z = 66
x = 60°
y = 54°
z = 66° [sorry if this is confusing]
PROOF
x + y + z = 180
60 + 54 + 66 = 180
180 = 180
The problem can be solved by setting up and solving a system of equations based on the information given in the problem. Using these equations, we are able to establish a relationship between the angles and thus calculate their individual measures.
Explanation:To solve this problem, we need to set up and solve a system of equations based on the information provided. We know from the problem that:
The sum of the angles of a triangle is 180 degrees, so x + y + z = 180.The sum of the measures of the second and third angles is twice the measure of the first, so y + z = 2x.The third angle is 12 more than the second, so z = y + 12.First, let's substitute z = y + 12 into the other two equations:
In x + y + z = 180, replace z with y + 12 to get x + y + y + 12 = 180; or, simplifying further, x + 2y = 168.In y + z = 2x, replace z with y + 12 to get y + y + 12 = 2x or, simplifying further, 2x = 2y + 12 or x = y + 6.We now substitute x = y + 6 into the equation x + 2y = 168 to find the values of x and y and hence z.

What is the equation of the line that has a slope of -4 and goes through (-1,6)
Answer:
y = - 4x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + c ← is the partial equation
To find c substitute (- 1, 6) into the partial equation

[tex]A=\frac{1}{4}\pi (12)^{2}-\frac{1}{2}(12)(12)[/tex]
[tex]A=(36\pi-72)\ cm^2[/tex]
simplify
Factor 36
[tex]A=36(\pi-2)\ cm^2[/tex]

All of the 4th grade teachers and students from Cambridge went on a field trip to an art museum. Tickets were $5.50 per teacher and $3.00 for each student. This group paid $29.00 in total. The next month, the same group visited a science museum where the tickets were $22.00 for teachers and $11.50 for students. The group paid $113.00 in total. Find the number of teachers and students on the field trips.
Answer:
Students= 6
Teachers= 2
Step-by-step explanation:
Given: Art museum trip:
Cost of ticket= $5.5 per teacher and $3 per student.
Total amount paid= $29.
Science trip:
Cost of ticket= $22 per teacher and $11.5 per student.
Total amount paid= $113.
Lets assume number of teacher be "x" and number of students be "y".
Now, forming an equation for cost of each trip.
we know, total cost= [tex]cost\ of \ each\ ticket \times numbers\ of\ tickets[/tex]
∴Art museum trip, [tex]5.5x+3y= 29[/tex] ---- 1st equation
Science museum trip, [tex]22x+11.5y= 113[/tex] ---- 2nd equation
Next using elimination method to find number teacher and students
[tex]5.5x+3y= 29\\22x+11.5y= 113[/tex]
Multiplying both side of 1st equation by 4
∴ [tex]22x+12y= 116\\22x+11.5y= 113[/tex]
changing sign of 2nd equation on both side and solving it.
∴ [tex]0.5y= 3[/tex]
Dividing both side by 0.5
[tex]y= \frac{3}{0.5}= 6[/tex]
Hence, number of students on field trip was 6.
Subtituting the value of y in 1st equation to find the number of teachers in field trip.
[tex]5.5x+3y= 29[/tex]
⇒ [tex]5.5x+3\times 6= 29[/tex]
⇒ [tex]5.5x+18= 29[/tex]
Subtracting both side by 18
⇒ [tex]5.5x= 11[/tex]
Dividing both side by 5.5
⇒ [tex]x= \frac{11}{5.5}= 2[/tex]
Hence, there were 2 teachers on field trips.

What is the equation of the line that is parallel to the line y - 1 = 4(x + 3) and passes through the point (4, 32)?
A: y=-1/4x +33
B: y=-1/4x + 36
C: y = 4x - 16
D: y = 4x + 16
Answer:
Option D: y = 4x + 16
Step-by-step explanation:
Given the line: y - 1 = 4(x + 3) ⇒ y = 4x + 13
The slope of the given line = m = 4
The required line is parallel to the given line
So, the slope of the required line = m = 4
So, the general equation of the required line: y = 4x + c
Where c is constant represents y-intercept
To find the value of c, substitute with the point (4,32)
At x = 4 y = 32
∴ 32 = 4 * 4 + c
∴ c = 32 - 16 = 16
∴ y = 4x + 16
The answer is option D: y = 4x + 16

Which equation represents the line shown
on the graph?
x = y + 2
y = x + 2
y = 2x
x = 2y
Answer: Third option:
Step-by-step explanation:
The equation in Slope Intercept form of a line that does not pass through the point (0,0), which is known as "Origin, is the following:
[tex]y=mx+b[/tex]
Where "m" is the slope of the line and "b" is the y-intercept.
The equation in Slope Intercept form of a line that passes through the Origin, is:
[tex]y=mx[/tex]
Where "m" is the slope of the line.
In this case you can observe in the picture attached that the line passes through the point (0,0).
You can also notice that "y" would be the Dependent variable and "x" the Independent variable.
Therefore, the equation of this must have this form:
[tex]y=mx[/tex]
The only equation that matches with that form, is the one given in the Third option. This is:
[tex]y=2x[/tex]
The linear equation shown in the graph can be written as.
y = 2x
Which equation represents the line shown on the graph?A general linear equation is written as:
y = ax + b
Where a is the slope and b is the y-intercept.
In this graph, we can see that the line intercepts the y-axis at y = 0, so we have:
y = ax
We also can see that the line passes through the point (1, 2), replacing these values in the equation we will get:
2 = a*1
2 = a
Then the linear equation is:
y = 2x
The third option.

To solve this, we need to consider that for every book purchased, he gets an additional book without cost. Therefore, Julian gets 2 books each time he makes a purchase for one book. As he bought 8 books, we simply need to double that amount to account for the free books he received.
To calculate: 8 books purchased × 2 = 16 books altogether.
Julian would have a total of 16 books by the end of the year after his purchases and receiving the complementary books.
1. Justin divided 403 by a number and got a quotient of 26 with a remainder of 13. What was the
number Justin divided by?
a. 13
b. 14
c. 15
d. 16
Answer:
15
Step-by-step explanation:
First subtract the remainder from 403 to get 390. then divide 390 by 26 to get 15.
The number used by Justin used to divide 403 to get a quotient of 26 with a remainder of 13 is 15.
What number was used to divide 403?
Division is theartimetic process used to divide a number into equal parts using another number. The sign used to denote division is ÷.
In order to detemine the number used to divide 403, take the following steps:
Subtract 13 from 403 = 403 - 13 = 390
Now divide 390 by 26: 390 / 26 = 15

Answers:
These are the three major and pure mathematical problems that are unsolved when it comes to large numbers.
The Kissing Number Problem: It is a sphere packing problem that includes spheres. Group spheres are packed in space or region has kissing numbers. The kissing numbers are the number of spheres touched by a sphere.
The Unknotting Problem: It the algorithmic recognition of the unknot that can be achieved from a knot. It defined the algorithm that can be used between the unknot and knot representation of a closely looped rope.
The Large Cardinal Project: it says that infinite sets come in different sizes and they are represented with Hebrew letter aleph. Also, these sets are named based on their sizes. Naming starts from small-0 and further, prefixed aleph before them. eg: aleph-zero.

The vertex of a parabola is at (8,-1)and its y-interpret is-17. Which function represents the parabola
Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 1), thus
y = a(x - 8)² - 1
To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.
- 17 = a(0 - 8)² - 1
- 17 = 64a - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
a = [tex]\frac{-16}{64}[/tex] = - [tex]\frac{1}{4}[/tex]
y = - [tex]\frac{1}{4}[/tex](x - 8)² - 1 → D
