A use bike costs $75 a new one costs $300. how many times more expensive is a new bike compare with a use bime
Answer:
300-75=225
Step-by-step explanation:
The proportionality constant is k = 4
The cost of the new bike is 4 times the cost of used bike
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportionality constant be represented as k
Now , the cost of used bike A = $ 75
The cost of new bike B = $ 300
The proportionality constant k = cost of new bike B / cost of used bike A
Substituting the values in the equation , we get
The proportionality constant k = 300/75
The proportionality constant k = 4
Therefore , the new bike is 4 times the cost of used bike
Hence , the proportionality constant is 4

this hard:( i need help :(
Answer:
[tex]33,680 cm^2[/tex]
Step-by-step explanation:
The formula needed for this problem is..
[tex]S.A=2(l*w)+2(l*h)+2(w*h)[/tex].
Given that;
The height of the door= 200cm
The length of the door= 3cm
The width of the door= 80cm
Now, substitute the formula with the information given.
[tex]S.A= 2(3*80)+2(3*200)+2(80*200)[/tex]

Answer:
None of given x = -1²/₇Step-by-step explanation:
-(-10x - 8) = -(4x + 10)
10x + 8 = -4x - 10
-8 -8
10x = -4x - 18
+4x +4x
14x = -18
÷14 ÷14
x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇
I think you meant -(10x-8)=-(4x+10)
Then:
-(10x - 8) = -(4x + 10)
-10x + 8 = -4x - 10
-8 -8
-10x = -4x - 18
+4x +4x

which property is needed to solve x/5=13
Answer: Multiplication property of equality
This is the idea that if a = b, then a*c = b*c for any real numbers a,b,c
It allows us to multiply both sides by the same number.
In this case, we multiply both sides by 5 to get
x/5 = 13
5*(x/5) = 5*13 ... multiplying both sides by 5
x = 65

A polynomial has zeros of 7, 6.
What is the minimum degree of the polynomial?
The minimum degree of the polynomial is 2.
Given the polynomial has zeros of 7, 6 means it has total of 2 zeroes. So it has only two factors possible [tex](x-7) and (x-6)[/tex] and on multiplying these factors we finally had a polynomial of degree 2 like[tex](ax^{2} +bx+c)[/tex].
So the given polynomial be a quadratic polynomial which has degree of 2.
Hence the minimum degree of the polynomial is 2.

Part (a)
Answer: -2-----------
Explanation:
Draw a vertical line through -2 on the x axis. This vertical line will cross the blue parabola at some point P. From point P, draw a horizontal line to the y axis. You should arrive at y = -2. Figure 1, in the attached diagram below, shows this process.
================================================
Part (b)
Answers: x = -3 or x = 1-----------
Explanation:
Draw a horizontal line through y = 1 on the y axis. This is because y = f(x).
This horizontal line crosses the parabola at two places. Drop a vertical line straight down to the x axis to note the x values that make f(x) = 1 true.
You should find the solutions to be x = -3 and x = 1
See figure 2.

The triangles shown below must be congruent is True statement.
What is Congruency?Two geometric figures are said to be congruent, or to be in the relationship of congruence, if one can be superimposed on the other and they correspond throughout.
As, Two triangles are congruent if their two angles and included sides are equivalent to the other triangle's two angles and included side.
Confirm that the triangles are congruent:
Both of the triangles given are right-angled triangles.
The included side between the angles 45° and 90° in both triangles is 12 units.
This is a necessary condition for the ASA congruence rule.
