The measure of the angle of the triangle ∠BCD = 13°
Given data ,
Let the triangle be represented as ΔBCD
Now , in triangle BCD, we are given the following angle measurements:
angle CDE = (9x - 12)°
angle BCD = (2x + 3)°
angle DBC = (3x + 5)°
From the exterior angle theorem , we get
∠CDE = ∠BCD + ∠DBC
On simplifying , we get
9x - 12 = 2x + 3 + 3x + 5
9x - 12 = 5x + 8
Subtracting 5x on both sides and adding 12 , we get
4x = 20
Divide by 4 on both sides , we get
x = 5
So , the measure of angle ∠BCD = 2(5) + 3
m∠BCD = 13°
Hence , the angle is m∠BCD = 13°

Here, we want to find the limit shown
To do this, we start by factorizing the numerator
Thus, we have that as:
\(\begin{gathered} 3t^2-7t\text{ + 2 = 3t}^2-6t-t+2 \\ =\text{ 3t\lparen t-2\rparen-1\lparen t-2\rparen = \lparen3t-1\rparen\lparen t-2\rparen} \end{gathered}\)Now, from here, we have the original fraction reduced to the following:
\(\begin{gathered} \frac{3t^2-7t+2}{2-t}\text{ = }\frac{(3t-1)(t-2)}{2-t}\text{ = }\frac{-(2-t)(3t-1)}{2-t} \\ \\ =\text{ -\lparen3t-1\rparen = 1-3t} \end{gathered}\)Finally, we find the limit as follows:
\(\lim_{t\to2}\text{ }\frac{3t^2-7t+2}{t-2}\text{ = }\lim_{t\to2}\text{ 1-3t = 1-3\lparen2\rparen = 1-6 = -5}\)Multiply with decimal numbers:

Are the graphs of y= 1/3x-4 and y-2=-3(x-4) parallel, perpendicular, or neither
Answers
Answer:
They are perpendicular
Step-by-step explanation:
the first graph has 1/3 as its slope.
The inverse of 1/3 is the negative reciprocal, or -3/1, which is the same as -3.
Thus, as the second graph’s slope is -3, it is the inverse of the first graphs slope, which means the two graphs represent lines which are perpendicular to each other.

What is Linear Equation in Two Variables?
A linear equation in two variables is one that is stated in the form ax + by + c = 0, where a, b, and c are real integers and the coefficients of x and y, i.e. a and b, are not equal to zero.
Solution:
Let,
Number of Soccer Balls = x
Number of T-Shirts = y
Equation 1:
x + y = 84 -----------(i)
Equation 2:
25x + 9.5y = 1046 ----------(ii)
Multiplying Equation 1 by 25
25x + 25y = 2100 ---------(iii)
Substracting Equation2 from Equation 1
15.5y = 1054
y = 68
So, x = 16

Answers
Answer:
There is a 0.15625 = 15.625% probability that you choose each answer at random and get 4 of the questions correct.
The formula for the probability of x successes is:
The parameters are given by:
n is the number of trials of the experiment.
p is the probability of success on a single trial of the experiment.
For this problem, we have that:
There are 5 questions, hence n = 5.
Each question has two options, true or false, p = 1/2.
The probability of 4 correct is given by P(X = 4)
P(X = 4) = 5 x (0.5)^4 x (0.5) = 0.15625.
0.15625 = 15.625% probability that you choose each answer at random and get 4 of the questions correct.

If my bowl of easter candy has colorful foil-wrapped chocolate eggs. there are 5 gold, 7 blue, and 10 pink. The probability that she reaches in without looking and gets a chocolate candy wrapped in pink foil is 0.45.
How to find the probability?Total color = 5 gold + 7 blue + 10 pink
Total color = 22
Now let find the probability that she reaches in without looking and gets a chocolate candy wrapped in pink foil
Probability (pink) = 10/22

A state university is interested in where its students come from. They survey 300 of its students to find out if they are in-state, out-of-state, or foreign students. Match the vocabulary word with its corresponding example.
Answers
In-state corresponds to students who are residents of the same state as the university, out-of-state corresponds to students from different states, and foreign corresponds to students from countries other than the university's country.
To match the vocabulary word with its corresponding example in the context of the state university survey, we need to understand the terms and their meanings.
Here are the vocabulary words and their corresponding examples:
Vocabulary Word: In-state
Example: A student who is a resident of the same state where the university is located.
They pay lower tuition fees compared to out-of-state or foreign students.
Vocabulary Word: Out-of-state
Example: A student who is not a resident of the state where the university is located.
They typically pay higher tuition fees compared to in-state students.
Vocabulary Word: Foreign
Example: A student who is from a country other than the country where the university is located.
They are international students who may have different visa requirements and tuition fees.
To match these vocabulary words with their corresponding examples:
In-state: A student from the same state as the university, paying lower tuition fees.
Out-of-state: A student from a different state than the university, paying higher tuition fees.
Foreign: A student from a country other than the country where the university is located, with potential differences in visa requirements and tuition fees.
By associating each vocabulary word with its respective example, we can accurately describe the three categories of students based on their residency and origin in the context of the state university's survey.

A cylinder has a radius of 4 millimeters. Its volume is 200.96 cubic millimeters. What is the height of the cylinder?
Answers
Answer:
3.999 millimeters.
Step-by-step explanation:
To find the height of the cylinder, we can use the formula for the volume of a cylinder:
V = πr²h
Given that the radius (r) of the cylinder is 4 millimeters and the volume (V) is 200.96 cubic millimeters, we can substitute these values into the formula and solve for the height (h).
200.96 = π(4²)h
200.96 = 16πh
To solve for h, we can divide both sides of the equation by 16π:
200.96 / (16π) = h
Using a calculator, we can calculate the approximate value of h:
h ≈ 200.96 / (16 × 3.14159)
h ≈ 3.999
Therefore, the height of the cylinder is approximately 3.999 millimeters.

Answers
The amount that the taxpayer is owing in taxes is $2,691.05.
We have,
Income tax payable refers to a business organization's tax liability to the government in the jurisdiction in which it operates. The amount of liability will be determined by the company's profitability over a given time period and the applicable tax rates. Tax payable is considered a current liability rather than a long-term liability because it must be settled within the next 12 months.
Based on the table, we are using the tax rate of 15% for the taxable income of $11,757.
The tax payable will equals to:
= 15%*$11,757 + $927.50
= $1,763.55 + $927.50
= $2,691.05

Determine whether each relation is a function. {(3, 2), (-1, 3), (5, 2)} and {(9, -1), (3, 6), (-2, 4), (3, 0)}
Answers
We can state that the given relations:
{(3, 2), (-1, 3), (5, 2)} is a function.
{(9, -1), (3, 6), (-2, 4), (3, 0)} is not a function.
What Makes a Relation a Function?A relation is a function if each of the x-values in the relation has exactly one corresponding y-value it is related to.
Given the relation with the ordered pairs, {(3, 2), (-1, 3), (5, 2)}, we can see that each x-value has exactly one y-value.
For the relation, {(9, -1), (3, 6), (-2, 4), (3, 0)}, we can observe that the x-value "3" has three corresponding y-values, "6, and 0", therefore, it is not function.
Therefore, we can state that the given relations:
{(3, 2), (-1, 3), (5, 2)} is a function.
{(9, -1), (3, 6), (-2, 4), (3, 0)} is not a function.
