Answer:
e= 2
W= 15
m= 9
Step-by-step explanation:
for e: yout multiply 5 x 7 to get 35 so 2 x 7 = 14
for W: 20/10 = 2 so divide 30/2 to get 15
for m: 11 x 2 = 22 so do 18 divided 2 to get 9
Answer:
E = 2
W = 15
M = 9
Step-by-step explanation:
You just have to make the denominator / numerator the same.
[tex]\frac{E}{5}[/tex] = [tex]\frac{14}{35}[/tex]
Multiply the first fraction by 7 so that their denominators are both 35.
[tex]\frac{7E}{35}[/tex] = [tex]\frac{14}{35}[/tex]
7E = 14
E = 14 ÷ 7
E = 2
[tex]\frac{20}{30}[/tex] = [tex]\frac{10}{W}[/tex]
Multiply the second fraction by 2 so that their numerators are both 20.
[tex]\frac{20}{30}[/tex] = [tex]\frac{20}{2W}[/tex]
2W = 30
W = 30 ÷ 2
W = 15
[tex]\frac{M}{11}[/tex] = [tex]\frac{18}{22}[/tex]
Multiply the first fraction by 2 so that their denominators are both 22.
[tex]\frac{2M}{22}[/tex] = [tex]\frac{18}{22}[/tex]
2M = 18
M = 18 ÷ 2
M = 9
Lines AAA, BBB, and CCC show proportional relationships.
Which line has a constant of proportionality between yyy and xxx of 333?
The line A has the constant of proportionality between x and y as 5.
What do you mean by constant of proportionality?In mathematics, we use the constant of proportionality to determine the type of proportionality, whether direct or indirect.
The proportionality constant aids in the solution of equations encompassing ratios and proportions.If one quantity increases, other quantity increases, the two quantities are considered to be proportional. Furthermore, as one quantity decreases, so does the other.For, the data given in the question;
Given lines A, B, and C Obtaining the equation for the line yields the proportionality constant.
1) Line A intersects (0,0) and (1, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(1 - 0)]×(x - 0)
y = 5x
y/x = 5
The proportionality constant between y and x is 5.
2) Line B traverses (0,0) and (3, 5). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(5 - 0)/(3 - 0)]×(x - 0)
y = 5x/3
y/x = 5/3
The proportionality constant between y and x is 5/3.
3) Line C intersects (0,0) and (3, 2). Line A's equation is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)]×(x - x₁)
Substitute the values;
y - 0 = [(3 - 0)/(2 - 0)]×(x - 0)
y = 3x/2
y/x = 3/2
The proportionality constant between y and x is 2/3.
Therefore, the constant of proportionality between x and y as 5 shown by line A.

What is the quadratic equation whose roots are 3/4 and 1/2 respectively
We need to know about the relation between roots of a quadratic equation for solving the question. The quadratic equation with roots 3/4 and 1/2 is [tex]8x^{2} -10x+3=0[/tex]
Quadratic equation is an equation with the highest order of variable being 2. Roots of a quadratic equation are the values that satisfy the equation.Since quadratic equation has the highest order as 2, the equation has two roots. Roots of a quadratic equation can be real and unique, real and equal or imaginary. The roots of a quadratic equation can be used to get the quadratic equation itself.
Let there be a quadratic equation:
[tex]ax^{2} +bx+c=0\\x^{2} +\frac{b}{a} x+\frac{c}{a} =0[/tex]
Let the roots of the quadratic equation be α and β, then
α+β=-b/a
αβ=c/a
In this question we know the two roots are 3/4 and 1/2. So we can derive the quadratic equation from them
[tex]\frac{3}{4} +\frac{1}{2} =\frac{-b}{a} \\\frac{-b}{a} =\frac{5}{4}[/tex]
[tex]\frac{3}{4}[/tex]×[tex]\frac{1}{2} =\frac{c}{a}[/tex]
[tex]\frac{c}{a} =\frac{3}{8}[/tex]
The quadratic equation is:
[tex]x^{2} -\frac{5}{4} x+\frac{3}{8} =0\\8x^{2} -10x+3=0[/tex]
Therefore we found the quadratic equation with roots 3/4 and 1/2 to be [tex]8x^{2} -10x+3=0[/tex]

i need help finding the angles
Answer:
all angles are 60 degrees
Step-by-step explanation:
since all sides are equal, all angles will be equal so its a equilateral triangle
all angles in a equilateral triangle are 60 as 180/3 is 60
so all angles equal 2x
2x = 60

determine whether each function has line symmetry.
Answer: 1 and 3 dont 2 and 4 do have a line of symmetry
Step-by-step explanation:
Graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The line of symmetry is an imaginary line that runs through the centre of a line or shape creating two perfectly halves.
To check a function to be symmetrical about the origin we need to replace y with minus y and x with minus x and the function must be equal to original function.
In the given graphs, 1 and 3 are not symmetrical and 2 and 4 are symmetrical.
Hence graphs 1, 3 function are not line symmetry and 2 and 4 have line symmetry.

the width, length, and height of a rectangular prism are each increased by $10\%$. what is the percent increase in the volume of the prism? express your answer to the nearest whole number.
The volume of the rectangular prism will increase by 33% if the width, length, and height are each increased by 10%.
Every three-dimensional object occupies some space. This space is measured in terms of its volume. Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
The formula for the volume of a rectangular prism is:
V = l x w x h
where
“l” is the base length
“w” is the base width
“h” is the height of the prism
If the width, length, and height are each increased by 10%, the equation will now become:
[tex]V_{2}= 1.10 l * 1.10 w*1.10h[/tex]
[tex]V_{2}= 1.331* l*w*h[/tex] V = l*w*h
[tex]V_{2}= 1.331* V[/tex]
Hence, if the width, length, and height are each increased by 10%, the volume of the rectangular prism will increase by 33%.

Write a polynomial function of least degree with integral coefficients that has the given zeros.
Answer:
The required polynomial is:
[tex]f\left(x\right)=x^3+8x^2+19x+12[/tex]
Step-by-step explanation:
Given the zeros
-4, -1, -3
Zeros can be written as:
x = -4, x = -1, x = -3
Finding the factors
x = -4
x +4 = 0
x = -1
x + 1 = 0
x = -3
x + 3 = 0
Thus, the factor are:
(x+4) (x+1) (x+3)
The original function can be computed by multiplying the factors
[tex]\left(x+4\right)\left(x+1\right)\left(x+3\right)=0[/tex]
as
[tex]\left(x+4\right)\left(x+1\right)=x^2+5x+4[/tex]
so the expression becomes
[tex]\left(x^2+5x+4\right)\left(x+3\right)=0[/tex]
Distribute parentheses
[tex]x^2x+x^2\cdot \:3+5xx+5x\cdot \:3+4x+4\cdot \:3=0[/tex]
[tex]x^2x+3x^2+5xx+5\cdot \:\:3x+4x+4\cdot \:\:3=0[/tex]
[tex]x^3+3x^2+5x^2+15x+4x+12=0[/tex]
Add similar elements: [tex]3x^2+5x^2=8x^2[/tex]
[tex]x^3+8x^2+15x+4x+12 = 0[/tex]
Add similar elements: [tex]15x+4x=19x[/tex]
[tex]x^3+8x^2+19x+12=0[/tex]
Thus, the required polynomial is:
[tex]f\left(x\right)=x^3+8x^2+19x+12[/tex]

A reasonable estimate for how long the job will take if she has her two sons help if they each work at approximately the same rate as Astrid is 5.75 hours.
Outside of her cabin, Astrid is painting. She is aware that if she works alone, the task will take her 23 hours to finish. If her two boys labor at roughly the same rate as Astrid, a fair estimate of how long the job will take with their assistance is
Astrid is painting the outside of her cabin = 23 hours
Astrid has her two sons help if they each work at approximately the same rate as Astrid is 23/2 = 11.5
Then 11.5/2 = 5.75 hours.
The work is calculated using the work formula. Let's review what work means before learning the formula. When we apply a force to an item and the object is moved, we say that work has been done. The work done becomes zero if there is no displacement in the direction of the force. Calculating the amount of labor required to move an object is done using the work formula.
