Answer:
m∠A = 60
m∠D = 60
Step-by-step explanation:
∆ABC and ∆DEF are congruent triangles
So,
m∠A = m∠D
x + 30 = 2x
2x - x = 30
x = 30
So,
m∠A = x + 30 = 30 + 30 = 60
m∠D = 2x = 2(30) = 60
Thus, m∠A and m∠D are 60°

A rectangle is 5 inches long and 2x inches wide. The value of the perimeter in inches) is equal to the value of the area (in square inches). Find x.
Answer:
the width of the rectangle is -5/3 inches.
Step-by-step explanation:
To find the perimeter of the rectangle, we add together the lengths of all four sides. Since the rectangle is 5 inches long and 2x inches wide, the perimeter is given by:
Perimeter = 5 + 2x + 5 + 2x = 10 + 4x
To find the area of the rectangle, we multiply the length by the width. The area is given by:
Area = 5 * 2x = 10x
Setting the perimeter equal to the area, we have:
10 + 4x = 10x
Subtracting 10 from both sides, we have:
4x = 10x - 10
Combining like terms, we have:
-6x = -10
Dividing both sides by -6, we have:
x = 10 / -6
Simplifying, we have:
x = -5/3
-6x+3y=24 in slope intercept form

Breaking strengths of a random sample of 28 molded plastic housing were measured, and a sample standard deviation of S=19.52 was obtained. A confidence interval (439.23, 460.77) for the average strength of molded plastic housings were constructed from these results. What is the confidence level of this confidence interval?
The confidence interval of this confidence level as calculate from the given data is 3.68 and 99% respectively.
Number of random sample (n)=28
Sample Standard deviation (S)=19.52
Confidence interval = 439.23 - 460.77 = 21.54
t = s/root of n
=19.52 /5.29
=3.68
v = n -1 = 27
now, confidence level
= 1 - alpha
= 99%
Confidence Interval, put simply, is a range within which we are confident that the genuine value exists. The probability that a confidence interval will contain the real parameter value depends on the confidence level that is chosen for the interval.

The vertices of a rectangle are W(1, 2) X(4, 2) Y(4, 23) and Z(1, 23) Find the perimeter of the rectangle. Use words, numbers, or models to justify your answer.
The vertices of a rectangle are W(1, 2) X(4, 2) Y(4, 23) and Z(1, 23) Find the perimeter of the rectangle is 16.
Step-by-step explanation:We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

5400 dollars is placed in an account with an annual interest rate of 6.75%. To the nearest tenth of a year, how long will it take for the account value to reach 11200 dollars?
The time needed for the account value to reach 11200 dollars is approximately 15.9 years.
What is the time required to reach the accrued amount?Simple interest formula is expressed as;
A = P( 1 + rt )
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given the data in the question;
Accrued amount A = $11200 Principal P = $5400Interest I = 6.75%Time r = ?Plug the given values into the above formula and solve for time t.
A = P( 1 + rt )
A/P = 1 + rt
( A/P - 1 ) = rt
t = ( A/P - 1 ) / r
t = ( $11200/$5400 - 1 ) / 6.75%
t = ( $11200/$5400 - 1 ) / 6.75/100
t = ( 56/27 - 1 ) / 0.0675
t = ( 29/27 ) / 0.0675
t = 15.9 years.
Therefore, the required time to reach the accrued amount is 15.9 years.

We can estimate the number of adult partons at 2187 by solving equations.
What do we mean by equations?The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.
A function is an equation that has only one answer for y for every possible value of x.
When utilizing a function, each input of a specific type receives exactly one output.
A function is commonly referred to as f(x) or g instead of y. (x).
Because f(2) instructs us to do so, we should figure out the value of our function when x is equal to 2.
So, the total number of adults present was thus:
Let a be an adult, and b and c be kids.
Ticket totals:
a + c = 5200
c = (5200-a)
Total amount:
7.50a + 4.50c = 29961
In the first equation, swap out c with (5200-a).
7.5a + 4.5(5200-a) = 29961
7.5a + 23400 - 4.5a = 29961
7.5a - 4.5a = 29961 - 23400
3a = 6561
a = 6561/3
a = 2187
Therefore, we can estimate the number of adult partons at 2187 by solving equations.

For the function in the given case the constraint on domain can be written as x ≥ 182. The correct option is (a).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
Suppose the amount of money spent be x.
And, the number of food items be y.
Now, as per the question the function can be written as follows,
y = x/182
As the number of food items can only be positive integers, the values of x must be the multiples of 182.
Thus, the expression for the domain can be written as x ≥ 182.

Find m in equation, W=1/2*m*v squared?
Answer: To find the value of m in the equation W = 1/2 * m * v^2, you need to know the values of W and v. The variable m represents the mass of the object, and W represents the kinetic energy of the object. The equation states that the kinetic energy of an object is equal to 1/2 of its mass multiplied by its velocity squared.
If you are given the values of W and v, you can solve for m by rearranging the equation as follows:
m = 2 * W / v^2
Plugging in the values of W and v will give you the value of m.
For example, if W = 100 joules and v = 10 meters per second, the equation would be:
m = 2 * 100 joules / 10 m/s^2 = 20 kilograms
This is the mass of the object.
[tex]m=\frac{2W}{v^{2} }[/tex].
Step-by-step explanation:1. Write the expression.[tex]W=\frac{1}{2} mv^{2}[/tex]
2. Divide both sides of the equation by [tex]\frac{1}{2}[/tex] and [tex]v^{2}[/tex].[tex]\frac{W}{\frac{1}{2} v^{2} }=m\\ \\[/tex]

The owner of a factory wants to determine a confidence interval for the average wages at his factory. The population average wages is unknown. However, the owner was able to take a random sample of 64 workers. He found that the average salary for this sample of workers is $50,000. The population standard deviation is $3000. He calculated a 99% confidence interval for the population average wages at the factory. Which of the following choices is correct? Assume the distribution of wages is normally distributed.
4,034.06 ,5,965.94 are confidence interval for the population average wages at the factory.
What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94
