how do I find x and y? I don't really want the answer but I want to know what to solve in order to get x and y
Answer:
y = 21°
Step-by-step explanation:
both are parallel lines, and that means
16x - 23 = 10x + 1
16x - 10x = 23 + 1
6x = 24
x = 4
---------------------------
taking 16x - 23
16 (4) - 23 = 64 - 23 = 41
both angles value is = 41°
------------------------------------
62° + x = 180
x = 180 - 62 = 118°
----------------------------------
the sum of all the angles inside the triangle is equal to 180°
41° + 118° + y = 180°
y = 21°
4 more than 3 times a number is 5
Answer:
0.33
Step-by-step explanation:
To solve this, you first write the problem as an algebra equation as follows: 3x + 4 = 5
Then you solve the equation by subtracting 4 from both sides, and then divide both sides by 3. Here is the math to illustrate better:
3x + 4 = 5
3x + 4 - 4 = 5 - 4
3x = 1
3x/3 = 1/3
x = 0.33
Answer = 0.33

at the city museum child admission is $5.90 and adult admission is $9.90 on Tuesday twice as many adult tickets as child tickets were sold for a total sales of $745.30how many child tickets were sold that day
To find how many child tickets were sold on Tuesday you must first call:
X= number of child tickets
Y= number of adult tickets
Then you can propose the following equation:
Also, adult tickets sold were double of child tickets so
\(Y=2\cdot X\)Replacing in the equation:
\(\begin{gathered} X\cdot5.90\text{ + (2}\cdot X)\cdot9.90\text{ = 745.30} \\ X\cdot5.90\text{ + 19.80 }\cdot X\text{ = 745.30} \\ 25.70\cdot X\text{ = 745.30} \\ X=29 \\ Y=58 \end{gathered}\)So the child tickets sold that day were 29 tickets.

Step-by-step explanation:
measure of a = 9 degree
angle POM = 48 degree = angle NMO [ AIA}
HOPE IT HELPS
Answer:
Below
Step-by-step explanation:
We are given that <PMO= (3a+15)° and NMO= (6a-6)°
Notice that the sum of <PMO and <NMO gives a right angle.
● <PMO+<NMO = 90°
● 3a+15+6a-6 = 90
● 9a + 9 = 90
Substruct 9 from both sides
● 9a +9 -9 = 90 -9
● 9a = 81
Divide both sides by 9
● 9a/9 =81/9
● a = 9
So the value of a is 9°
■■■■■■■■■■■■■■■■■■■■■■■■■■
MN and PO are parallel since MNOP is a rectangle.
MO is crossing MN and PO so <POM and < NMO are alternate interior angles wich means that they have the same size.
● <NMO = <POM
● <POM = 6a-6
The value of a is 9°
● <POM = 6*9-6 = 48°
So <POM = 48°
write the equation of a quadratic function that contains the points (1,21), (2,18), and (-1,9)
Answer:
The equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is \(y = -3\cdot x^{2}+6\cdot x +18\).
Step-by-step explanation:
A quadratic function is a second order polynomial of the form:
\(y = a\cdot x^{2}+b\cdot x + c\) (1)
Where:
\(x\) - Independent variable.
\(y\) - Dependent variable.
\(a\), \(b\), \(c\) - Coefficients.
From Algebra we understand that a second order polynomial is determined by knowing three distinct points. If we know that \((x_{1}, y_{1}) = (1, 21)\), \((x_{2},y_{2}) = (2,18)\) and \((x_{3}, y_{3}) = (-1, 9)\), then we construct the following system of linear equations:
\(a+b+c = 21\) (2)
\(4\cdot a + 2\cdot b + c = 18\) (3)
\(a - b + c = 9\) (4)
By algebraic means, the solution of the system is:
\(a = -3\), \(b = 6\), \(c = 18\)
Therefore, the equation of a quadratic function that contains the points (1, 21), (2,18) and (-1, 9) is \(y = -3\cdot x^{2}+6\cdot x +18\).

A consultant charges $45 for each hour she works on a consultation, plus a flat $30
consulting fee. How many hours of work are included in a $210 bill for a consultation?
A. 2 4/5
B. 4
c. 4 2/3
D. 5 1 / 2
E. 7
Answer:
A. 2 4/5
Step-by-step explanation:
To find how many hours she worked for $210, you must get the amount of money she gets in 1 hour.
Because she charges $43 dollars every hour, and fines a fee of $30 flat, we must add both of the amount to get how many she earns in 1 hour.
So:
$45 + $30= $75
She earn $75 in 1 hour.
Next, divide $210 dollars that she earned for working for hour(s) to the amount of money she earned in 1 hour to find how many hours she worked.
So:
$210 ÷ $75= 2.8 hours
The answer is 2.8 hours
Because the given answers is in fraction, we must change the decimal into a fraction.
To change a decimal into a fraction, you must place the decimal over its place value.
Because 8 in the decimal 2.8 is in the tenths place, you must place it over 10
So:
2.8 into a decimal is 2 8/10
Simplify (only simplify if possible):
Divide 8 and 10 to their GCF which is 2.
So:
8 ÷ 2= 4
10 ÷ 2= 5
So the fraction and the answer is now:
2 4/5

The age of the decaying sample according to the decay formula is 42,009 years.
The rate of radioactive carbon-14 decay depends on the function
\(A(t) = A_{0} e^{-0.0001216t}\)
where \(A_{0}\) is the quantity found in living plants and animals, t is in years, and is the age.
60% of the carbon-14 of a current-day sample was present in a sample taken from a refuse deposit close to the Strait of Magellan. We need to evaluate the age of the sample,
A = 60 % of \(A_{0}\) = (3/5)\(A_{0}\)
Putting this in the decay equation, we have,
\(\frac{3}{5} A_{0} = A_{0} e^{-0.0001216t}\\\\ 0.6= e^{-0.0001216t}\\ \\ln0.6 = -0.00001216t\\\\-0.51082 = -0.00001216t\\\\t = 42,008.68\)

the number of distinct seating arrangements when two seatings are considered the same when everyone has the same two without neighbors regard to whether they are right or left neighbors is:5!6⋅2=10.6⋅25! = 10
There are $(6-1)! = 5! = 120$ ways to seat six people around a circular table if the seatings are considered distinct. However, we must divide this number by $6$ to account for the fact that rotations of the same seating arrangement are considered the same. We also must divide by $2$ to account for the fact that reflections (i.e., reversing the order of people) of the same seating arrangement are also considered the same.

The robot moves in the positive direction along a straight line so that after t minutes its distance is s=6t^4 feet from the origin. (a) Find the average velocity of the robot over intervals 2, 4. We have the following data: Initial time, t₁ = 2 min.
Final time, t₂ = 4 min.The distance from the origin is given by s = 6t^4Therefore, s₁ = s(2) = 6(2^4) = 6(16) = 96 feet s₂ = s(4) = 6(4^4) = 6(256) = 1536 feet
We can find the average velocity of the robot over the interval 2, 4 as follows: Average velocity = (s₂ - s₁) / (t₂ - t₁)Average velocity = (1536 - 96) / (4 - 2)Average velocity = 1440 / 2Average velocity = 720 feet per minute(b) Find the instantaneous velocity at t=2.To find the instantaneous velocity at t = 2 min, we need to take the derivative of the distance function with respect to time. We have the distance function as:s = 6t^4 Taking derivative of s with respect to t gives the velocity function:v = ds / dt Therefore,v = 24t³At t = 2, the instantaneous velocity is:v(2) = 24(2)³v(2) = 24(8)v(2) = 192 feet per minute Therefore, the instantaneous velocity at t = 2 min is 192 feet per minute.

How many possible values can be assigned to type "logic"?
a.4
b.5
c.2
d.6
e.3
The number of possible values that can be assigned to the type "logic" is 2, and the correct answer is option c.2.
In logic, the type "logic" refers to a variable or proposition that can take on one of two possible values: true or false.
These values are commonly denoted as 1 (true) and 0 (false), or alternatively as "T" and "F".
Since the type "logic" can only have two possible values, the correct answer is option c.2.
There are no other valid values for this type.
It is important to note that in some programming languages or systems, additional representations or extensions of logic may exist.
For example, some languages may include a "null" or "undefined" value in addition to true and false.
However, in the context of a basic logic type, the number of possible values remains restricted to two: true and false.

Use a triple integral to find the volume of the solid enclosed by the paraboloids y = x^2 + z^2 and y = 32 - x^2 - z^2
The volume of the solid enclosed by the two paraboloids is approximately 1365.34π cubic units.
Here, we have to find the volume of the solid enclosed by the two paraboloids \(y = x^2 + z^2\) and \(y = 32 - x^2 - z^2\),
we need to set up a triple integral in cylindrical coordinates.
In cylindrical coordinates, we have:
x = r cos(θ)
z = r sin(θ)
y = y
The limits of integration for r, θ, and y will depend on the region of integration.
First, let's find the intersection points of the two paraboloids:
\(x^2 + z^2 = 32 - x^2 - z^2\\2x^2 + 2z^2 = 32\\x^2 + z^2 = 16\)
This represents a circular region with radius r = 4 in the x-z plane.
Now, let's find the limits of integration for r, θ, and y:
For r:
Since the circular region has a radius of 4, the limits of r will be from 0 to 4.
0 ≤ r ≤ 4
For θ:
The intersection points form a complete circle in the x-z plane, so the limits of θ will be from 0 to 2π.
0 ≤ θ ≤ 2π
For y:
The lower paraboloid is given by \(y = x^2 + z^2\), and the upper paraboloid is given by \(y = 32 - x^2 - z^2\).
The limits of y will be from the lower paraboloid to the upper paraboloid.
\(x^2 + z^2 \leq y \leq 32 - x^2 - z^2\)
Now, we can set up the triple integral to find the volume V:
V = ∫∫∫ (y) dy dθ dr
V = ∫∫∫ \((r^2 cos^2(\theta) + r^2 sin^2(\theta)) dy d\theta dr\)
V = ∫∫∫ \((r^2) dy d\theta dr\)
V = ∫∫ \((r^2) y|_{(x^2+z^2)}^{(32-x^2-z^2)} d\theta dr\)
V = ∫∫ \((r^2) (32 - 2x^2 - 2z^2) d\theta dr\)
V = ∫ \((32r^2 - 2r^2(x^2 + z^2)) d\theta dr\)
V = ∫ \((32r^2 - 2r^2r^2) d\theta dr\)
V = ∫ \((32r^2 - 2r^4) d\theta dr\)
Now, integrate with respect to θ from 0 to 2π:
V = ∫(0 to 2π) ∫(0 to 4) \((32r^2 - 2r^4)\) dr dθ
Now, integrate with respect to r from 0 to 4:
V = ∫(0 to 2π) \([(32/3)r^3 - (1/3)r^5] |_0 ^4\) dθ
V = ∫(0 to 2π) \([(32/3)(4^3) - (1/3)(4^5)]\) dθ
V = ∫(0 to 2π) [(32/3)(64) - (1/3)(1024)] dθ
V = ∫(0 to 2π) [682.67] dθ
V = 682.67 * (2π) - 682.67 * (0)
V = 1365.34π cubic units
Therefore, the volume of the solid enclosed by the two paraboloids is approximately 1365.34π cubic units.

The value will be $371.39.
What is compound interest?Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
The formula to calculate the compound amount after t years is given by :-
A =P \((1 + R)^{T}\)
where the interest rate is r and P represents the principal amount.
Given: $150 is the principal sum.
Interest is charged at a rate of 12%/0.12
A = 150 will be the amount compounded after 8 years.
A = 150 \(( 1 + 12 )^{8}\)
A =371.3944
A = $371.39
Hence, the value of $150 after eight years if you earn 12 percent interest per year would be $371.39.

Suppose a firm can sell it's output at p per unit and that its production function is given by y = AK∝Lβ, where K > 0 is capital input measured in machine-hours, L > 0 is labor input measured in worker-hours and A,∝, ß > 0 are parameters. The firm is perfectly competitive and the factor prices are r per hour and w per hour. (a) Show by partial differentiation that the production function has the property of increasing marginal productivity of capital (if ∝ > 1) and of labor (if ß > 1). Explain the economic significance of this. Does it explain why we normally assume that a and 3 are less than 1?
Increasing marginal productivity infers that extra units of capital and labor contribute more to yield, driving productive asset allotment. ∝ and ß < 1 expect reducing returns, adjusting with reality.
The production function has the property of increasing the marginal productivity of capital through Partial Differentiation.To appear that the generation work has to expand the marginal productivity of capital (in case ∝ > 1) and labor (on the off chance that ß > 1), we ought to take fractional subsidiaries with regard to each input calculation. For capital (K), the fractional subsidiary of the generation work is:
\(\dfrac{dy}{dK }= \alpha AK^{(\alpha-1)}L^\beta\)
Since ∝ > 1, (∝ - 1) is positive, which implies that the fractional subordinate \(\dfrac{dy}{dK}\) is positive. This shows that an increment in capital input (K) leads to an increment in yield (y), appearing to expand the marginal efficiency of capital.
Additionally, for labor (L), the fractional subordinate of the generation work is:
\(\dfrac{dy}{dL} = \beta AK^{\alpha}L^{(\beta-1)}\)
Since \(\mathbf{\beta > 1, (\beta-1)}\) it is positive, which implies that the halfway subordinate \(\dfrac{dy}{dL}\) is positive. This demonstrates that an increment in labor input (L) leads to an increment in yield (y), appearing to increase the marginal productivity
The economic importance of increasing marginal productivity is that extra units of capital and labor contribute more to yield as their amounts increment. This suggests that the more capital and labor a firm employments, the higher the rate of increment in yield. This relationship is vital for deciding the ideal assignment of assets and maximizing generation effectiveness.
In most generation capacities, it is accepted that ∝ and ß are less than 1. This presumption adjusts with experimental perceptions and financial hypotheses.
In case ∝ or ß were more prominent than 1, it would suggest that the marginal efficiency of the respective factor increments without bound as the calculated input increments.
In any case, there are decreasing returns to scale, which suggests that as calculated inputs increment, the Marginal efficiency tends to diminish. Therefore, accepting ∝ and ß are less than 1 permits for more reasonable modeling of generation forms and adjusts with the concept of diminishing marginal returns.

Since x is positive in the first and second quadrant, in the second quadrant, the value of x will be 180°-0° = 180°
Subsequent value of x equivalent to 0° will be addition of 180° to each previous value gotten. The values of x within the range given are as shown
x1 =0°
x2 = 180°-0° = 180(2nd quadrant)
x3 = 180°+180° = 360°
x4 = 360°+180° = 540°
x5 = 540°+180°=720°
x6 = 720°+180° = 900°
x7 = 900°+180° = 1080°
We can see from the values above that the values of x that falls within the given range are 540°, 720° and 900°. This gives the required answers in degrees.
How to find a quadratic equation with y-intercept and vertex? Explain with examples.
To find a quadratic equation with the y-intercept and vertex, follow these steps: identify the coordinates of the y-intercept and vertex, substitute them into the general form of the quadratic equation, solve for the coefficients, and substitute the coefficients back into the equation. For example, if the y-intercept is (0, 3) and the vertex is (-2, 1), the quadratic equation would be y = x^2 + x + 3.
To find a quadratic equation with the y-intercept and vertex, we can follow these steps:
Step 1: Identify the coordinates of the y-intercept. The y-intercept has the form (0, c), where c is the y-coordinate.Step 2: Identify the coordinates of the vertex. The vertex has the form (-b/2a, f(-b/2a)), where a, b, and c are the coefficients of the quadratic equation.Step 3: Substitute the coordinates of the y-intercept and vertex into the general form of the quadratic equation, y = ax^2 + bx + c.Step 4: Solve the resulting system of equations to find the values of a, b, and c.Step 5: Substitute the values of a, b, and c back into the general form of the quadratic equation to obtain the final equation.For example, let's say the y-intercept is (0, 3) and the vertex is (-2, 1). We can substitute these coordinates into the general form of the quadratic equation:
3 = a(0)^2 + b(0) + c
1 = a(-2)^2 + b(-2) + c
Simplifying these equations, we get:
c = 3
4a - 2b + c = 1
By substituting c = 3 into the second equation, we can solve for a and b:
4a - 2b + 3 = 1
4a - 2b = -2
2a - b = -1
By solving this system of equations, we find a = 1 and b = 1. Substituting these values back into the general form of the quadratic equation, we obtain the final equation:
y = x^2 + x + 3

To find a quadratic equation with a given y-intercept and vertex, you need the coordinates of the vertex and one additional point on the curve.
Start with the standard form of a quadratic equation: y = ax^2 + bx + c, where a, b, and c are constants.Use the vertex form of a quadratic equation: y = a(x - h)^2 + k, where (h, k) represents the coordinates of the vertex.Substitute the vertex coordinates (h, k) into the equation to obtain the equation in vertex form.Use the y-intercept to find another point on the curve. The y-intercept has the form (0, c), where c is the value of y when x is zero.Substitute the coordinates of the additional point into the equation to obtain a system of two equations. Solve the system to find the values of a, b, and c.Substitute the determined values of a, b, and c into the standard form of the quadratic equation to obtain the final equation.Example:
Suppose we want to find a quadratic equation with a y-intercept of (0, 4) and a vertex at (2, -1).
Using the vertex form, we have y = a(x - 2)^2 - 1.Substituting the y-intercept coordinates, we get 4 = a(0 - 2)^2 - 1, which simplifies to 4 = 4a - 1.Solving the equation above, we find a = 1.Substituting the values of a and the vertex coordinates into the vertex form equation, we have y = 1(x - 2)^2 - 1.Expanding the equation and simplifying, we get y = x^2 - 4x + 3.The final quadratic equation with the given y-intercept and vertex is y = x^2 - 4x + 3.To find a quadratic equation with a given y-intercept and vertex, you can use the vertex form of a quadratic equation and substitute the coordinates to obtain the equation. Then, use the y-intercept to find an additional point on the curve and solve a system of equations to determine the coefficients. Finally, substitute the coefficients into the standard form of the quadratic equation to get the final equation.
