Using inequalities, we can say that Yes, there are more than 1 possible ways to get the answer of inequalities.
What are inequalities?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
Given,
the wavelength is greater than 4/100 nanometer and
less than 4 x 10^-1 nanometer
Let wavelength = λ
4/100 ≤ λ ≤ 4/10
0.04 ≤ λ ≤ 0.4
or
1/50 ≤ λ ≤ 2/5
So, from the above three equations, we can conclude that there can be more possible ways to have more than 1 correct answer.

Find the measurement of the angle indicated for each trapezoid.
Answer:
∠ C = 50°
Step-by-step explanation:
• each lower base angle is supplementary to the upper base angle on the same side.
then
∠ C + ∠ D = 180°
∠ C + 130° = 180° ( subtract 130° from both sides )
∠ C = 50°

Are the functions of g(x)=(x-4)^2 and h(x)=x^2-4 equivalent? Explain your reasoning.
Answer:
[tex]g(x) = (x-4)^2\; and \;h(x)= x^2-4 \;are\;\bold{not}\;equivalent[/tex]
Step-by-step explanation:
For two functions g(x) and h(x) to be equivalent, they must have the same domain and range.
Domain is the set of all values of x(inputs) that result in a real and defined value for the function
Range is the set of all values of the function that it can take given the values of x in the domain
[tex]g(x)=(x-4)^2=16-8x+x^2\\[/tex]
Can be rewritten as
[tex]g(x) = x^2 -8x + 16[/tex] The domain of g is unrestricted, g can be any value so the
Domain of g: [tex]-\infty < x < \infty[/tex]
Range of g: Since [tex](x-4)^2[/tex] is always positive including 0, the range of g(x) is g(x) ≥ 0
[tex]h(x) = x^2 - 4[/tex]
Domain of h : [tex]-\infty < x < \infty[/tex] since x can be any value and we will still get a real number as function output
However x² is always zero or a positive number so we have the restriction
x² ≥ 0
Subtract 4 on both sides
x²-4 >= -4
But the above is nothing but the outputs of h(x)
So h(x) >= -4 and can be written as -4 ≤ x ≤ ∞
So we can see that, while the domains of the two functions are the same, their ranges are different
Hence the two functions g(x) and h(x) are not equivalent
Tip
If you have difficulty determining domain and range, take a specific value of x for both functions and check if the function output values are the same. It may not always be easy choosing an appropriate x value depending on the function
For x = 0
g(0) = (0-4)² = (-4)² = 16
h(0) = 0^2 -4 = 0-4 = -4
So we get different output values for the same input value for both functions and therefore they are not equivalent

5. Slope (m) = 5
6. y-intercept (b) = 15; x-intercept = -3.
7. See attachment below for the graph.
How to Write an Equation that Models a Situation?Using the information given, we can create an equation in slope-intercept form y = mx + b, where m would be the slope and b would be the y-intercept of the linear equation.
Let,
y = total costx = number of calendarm = cost per calendar = slope = 5b = initial value/y-intercept = 151. To create an equation that models the situation, substitute m = 5 and b = 15 into y = mx + b:
y = 5x + 15.
2. The variables and numbers in the equation are:
y = total cost
x = number of calendar
m = cost per calendar = slope = 5
b = initial value/y-intercept = 15
3. Substitute x = 200 into y = 5x + 15
y = 5(200) + 15
y = 1,015
Total cost = $1,015.
4. The equation in slope-intercept form is: y = 5x + 15
5. The slope (m) = 5
6. The y-intercept (b) = 15
To find the x-intercept, substitute y = 0 into y = 5x + 15
0 = 5x + 15
-5x = 15
x = 15/-5
x = -3
The x-intercept = -3.

Michael and Lauren each have a coin collection.
The number of coins in Michael's collection can be represented by x.
The number of coins in Lauren's collection is 5 times the number in Michael's collection.
The total number of coins in both collections is 366.
What is x, the number of coins in Michael's collection?
If the number of coins in Lauren's collection is 5 times the number in Michael's collection and the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61
The number of coins in Michael's collection = x
The number of coins in Lauren's collection is 5 times the number in Michael's collection
Then the number of coins in Lauren's collection = 5x
The total number of coins in both collection = 366
Combine the values and the equation will be
x+5x=366
Add like terms
6x= 366
x=[tex]\frac{366}{6}[/tex]
x=61
Hence, if the number of coins in Lauren's collection is 5 times the number in Michael's collection and the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61

5 friends went out to a tapas restaurant and ordered from the menu that included $4, $6 and $7 options. They ordered a total of 24 items. The number of $4 items was twice the $6 and $7 items combined. When they split the bill at the end, they each owed $23. How many of each type of item did they order?
The 5 friends ordered 16 items of $4 , 5 items of $6 , 3 items of $7 .
How to find solution of system of equations in two variables by substitution?Let p and q be two variables and
a₁p+ b₁q=c₁
a₂p+ b₂q =c₂
Where a₁, a₂, b₁, b₂, c₁, c₂ are constants then we can solve these simultaneous equations by substitution take value of p from equation (1) and then put it in (2) to get an equation for q only and then solve for q. Put value of q in equation (1) to get value of p.
Let the 5 friends ordered x number of $4 items , y number of $6 and z number of $7 items
They ordered total a total of 24 items.
Then, x+ y + z = 24 ....(1)
Given that $4 was twice the $6 and $7 items combined
Then, x =2( y+ z )
Put this expression of x in (1),we get
2(y+ z)+ y + z =24
3y + 3z =24
y + z =8 ....(2)
Also given that they split the bill at the end, they each owed $23
Therefore total bill will be 5 times $23 = 5*23 = $ 115
Total money spent on bill = $ 4x+6y+7z
Thus, 4x+6y+7z = 115
Again put x =2(y+ z) here and get
8(y+ z) +6y+ 7z =115
8y +8z + 6y +7z = 115
14y +15z = 115 ....(3)
Therefore, (2) and (3) is the system of equations we have to solve.
From (2) we get y =8 -z
Put this value of y into (3) and get
14(8-z)+15z =115
112 - 14z +15z =115
z= 115-112 = 3
Then, y = 8-z = 8-3 = 5
x = 2(y+ z)= 2(3+5) =16
Therefore x= 16 , y = 5, z=3 from system of equations generate by (2) and (3)
The 5 friends ordered 16 items of $4 and 5 items of $6 and 3 items of $7.

System of Equations: Setting up a system of equations containing the 2 unknown values, the substitution technique is also accustomed acquire associate degree equation with just one of the unknowns. The ensuing equation could then be resolved to search out the worth of the remaining unknown. From here, the second worth is also obtained by subbing the primary worth back to at least one of the equations.Let the amount of 10 % acid solution be " x " and the amount 40 % acid solution be " y " .
The total volume of the resulting solution is 60 L which can be given by
x + y = 60 .....(1)
The total acid in the resulting solution is 35 % acid solution which is given by 0.10 x + 0.40 y = 0.35(60) .....(2)
