The percentage of students that use other means to travel school is 24%
What is method for finding percentage?Percentage is the ratio of the number for which you want to find percentage to the total number with which you want to compare or out of and multiply this ratio with 100.
percentage = (part / whole) ×100
Given that a school has 825 total students.
Percentage of students travelling by car = 20%
Percentage of students travelling by bus = 48%
Percentage of students travelling by bicycle = 8%
Number of students travelling by car = 20% of 825 = (20/100)×825 = 165
Number of students travelling by bus = 48% of 825
= (48/100)×825 = 396
Number of students travelling by bus = 8% of 825 = (8/100)×825 = 66
Number of students travelling by other means = 825-165-396-66 = 198
Therefore, the Percentage of students travelling by other means = (198/825) ×100 = 24%

Step-by-step explanation:
The zeros of the given polynomial function are 1, -1 and 2
Given the polynomial function
First, we need to assume a value of x to check if it will give us zero after substituting:
Assuming x = 1
Since f(1) =0, hence x - 1 is a factor
Dividing x - 1 by the given polynomial function, we will have:
Equating the result to zero
x + 1 = 0 and x - 2 = 0
x = -1 and 2

Step-by-step explanation:
slope = rise/run = (difference in y)/(difference in x)
First, we find a difference in y.
Subtract any two values of y.
For example: 35 - 14 = 21
Now we find the corresponding difference in x.
Now subtract the x values corresponding to those y values in the same order.
-1 in x corresponds to 35 in y.
-4 in x corresponds to 14 in y.
That means your difference in x is the subtraction -1 - (-4) = -1 + 4 = 3
The difference in y is 21.
The difference in x is 3.
slope = (difference in y)/(difference in x) = 21/3 = 7

An item costs y dollars and then a 20% discount is applied. Create an expression that could represent the price of the item after the discount. Explain your reasonin
Answers
The percentage 20% of the costs y is given as 0.20y thus the expression which represents the price of the item after the discount is P = y - 0.20y.
What is the percentage?The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
It is known that x% of something y is given as,
x% of y = (x/100)y
Given that discount of 20% of y
20% of y = (20/100)y
20% of y = 0.20y
Now the final price = initial price - discount
Final price (P) = y - 0.20y
Hence"The percentage 20% of the costs y is given as 0.20y thus the expression which represents the price of the item after the discount is P = y - 0.20y".

Area of triangle = 1/2 * base*height
Area of triangle = (1*7*14)/2
Area of triangle = 49 [tex]m^{2}[/tex]
Now, the area of another same triangle will also be 49 [tex]m^{2}[/tex].
Now, we have:
Area of upper rectangle = length*breadth
Area of upper rectangle = 15*14
Area of upper rectangle = 210 [tex]m^{2}[/tex]
Area of middle rectangle = length*breadth
Area of middle rectangle = 15*7
Area of middle rectangle = 105 [tex]m^{2}[/tex]
Area of lower rectangle = length*breadth
Area of lower rectangle = 15.65*15
Area of lower rectangle = 234.75 [tex]m^{2}[/tex]
Now, the area of the wrapping paper will be the sum of all of these areas.
Area of paper = Area of 2 triangles + area of upper rectangle + area of middle rectangle + area of lower rectangle
Area of paper = 49+49+210+105+234.75

How do you proof that sqrt(2) is irrational?
I tried this,
p/q = sqrt(2)
p^2/q^2=2
p^2=2q^2
let p = q * sqrt(2) , (equation from top one)
(q*sqrt(2))^2=2q^2
2q^2=2q^2,
q=q
Is anything wrong or does this also prove that sqrt(2) is irrational, if so how?
Answers
Assume √2 is rational, so
√2 = p/q
for some relatively prime integers p,q - meaning we can't reduce p/q any further - and q ≠ 0.
Then
p = √2 q
and squaring both sides gives
p² = 2q²
This tells us that p² is even, so 2 divides p². But if 2 divides p², it must also divide p, since p is a square number. So p = 2r for some integer r, and we have
(2r)² = 2q²
4r² = 2q²
2r² = q²
We're in the same situation as before - 2 divides q², so 2 divides q. Both p and q are thus divisible by 2, but this contradicts our assumption that p and q are relatively prime, which means √2 cannot be expressed as a rational number p/q. Therefore √2 is irrational.

She walks a distance of 13.45 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.2 meters to the other side of the mirror, until she can see the top of the goalpost clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.35 meters. How tall is the goalpost? Round your answer to the nearest hundredth of a meter.
Answers
The goalpost is 15.13 meters tall which is labeled as X in the figure which has been attached below.
She walks 13.45 meters away from the goalpost, then places a mirror flat on the ground with an X in the center. She next walks 1.2 meters to the opposite side of the mirror, where she can easily see the top of the goalpost depicted in the X. Her partner determines that the distance between her eyes and the ground is 1.35 meters.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
As per the given information, the figure has been attached below.
Set up the proportional and solve for x
1.2 : 13.45 = 1.35 : x
⇒ 1.2 / 13.45 = 1.35 / x
Cross multiplication, and we get
⇒ 1.2x = 1.35 × 13.45
Divided by 1.2 into both sides of the above equation,
⇒ x = (1.35 × 13.45) / 1.2
⇒ x = 15.13
Therefore, the goalpost is 15.13 meters tall.

Answers
The set of the value for which the curve and line have no common point are is k ∈ (0 , 4).
The value for which the line is a tangent is k = 4.
The coordinates of the point where the line touches the curves is point of tangency = ( 1/2 , 2).
What is tangent?
Tangents in geometry are lines or planes that contact curves or surfaces at points where they are closer to the curve than any other lines or planes drawn through those points.
Given equations in the question:
y = kx² + 1
y = kx
Equating y
kx² + 1 = kx
kx² -kx + 1 = 0
This is Quadratic equation is of the form ax²+bx+c=0 where a , b and c are real also a≠0.
D = b²-4ac is called discriminant.
and we know that,
D >0 roots are real and distinct
D =0 roots are real and equal
D < 0 roots are imaginary ( not real ) and different
For no common solution D < 0
For tangent D = 0
so,
kx² -kx + 1 = 0
D = (-k)² - 4k = k² - 4k = k(k - 4)
k(k - 4) < 0
if 0 < k < 4
Hence values of k for which the curve and the line have no common points is k ∈ (0 , 4).
for tangent
k(k - 4) = 0
k is non zero
Hence k = 4
After putting the value of k, given equations are:
y = 4x² + 1
y = 4x
solving these equations to get value of x and y:
4x² + 1 = 4x
4x² - 4x + 1 = 0
(2x - 1)² = 0
x = 1/2
y = 2

What is in slope-intercept form?
Given a line's slope and the intercept it makes with the y-axis, one of the mathematical forms used to determine a straight line's equation is called the slope intercept form. The slope intercept form is expressed as y = mx + b, where m is the slope of the straight line and b is the y-intercept.changing 2x+3y=1470 to slope intercept form is solving for y
minus 2x both sides and divide by 3
y = -2/3x + 490
the slope is -2/3
the y intercept is y=490 or the point (0,490)
to graph it, I would start at the origin and go up 490 units on the y axis and put a point there
then go -2 units up (2 down) and 3 to the right and put a point there
then connect the 2 points with a line
in function notation, replace y with f(x) to get
