Line segment tv bisects angle stu. the measurement of angle stv is equal to (1/4x+8) degrees and the measurement of angle utv is (x+2) degrees. find the measurement of angle stu
The measurement of ∠STU is 20°.
Define Angle
When two rays are connected at their endpoints, they form an angle in geometry. We refer to these rays as the angle's sides or arms.
Components of an Angle
An angle is composed of the arms and the vertex as its two basic components:
The arms of the angle: The arms of the angle are the two rays that combine to form it at a common point.Point of the angle: The two rays share a vertex as a common terminus.Given, ∠STU = [tex](\frac {1}{4} x+8)[/tex]°
∠UTV = x+2°
Given, that the line TV bisects ∠STU,
∠STV = ∠UTV
Substitute their values,
[tex](\frac {1}{4} x+8)[/tex]° = x+2°
Calculating,
[tex]\frac{1}{4}x-x[/tex] = 2-8
[tex]-\frac{3}{4}x[/tex] = -6
x = [tex]-6*(-\frac{4}{3})[/tex]
x = 8
So, we know that:
∠STU = ∠STV + ∠UTV
= [tex](\frac {1}{4} x+8)[/tex]° +( x+2°)
= [tex](\frac {5}{4} x+10)[/tex]
Now, substitute the value of x,
∠STU = [tex](\frac {5}{4} )*8[/tex]°+10°
= 10° + 10°
= 20°
Therefore, the measure of ∠STU is 20°.

One cotton candy at the rodeo cost $5.25. When 4 friends purchases cotton candy, the expression 5.25(4) can be used to determine the total cost. What other expression can be used to determine the total cost?
The other expression for this scenario is 5.25 + 5.25 + 5.25 + 5.25
How to determine the other expression?From the question, we have the following parameters that can be used in our computation:
Cost of cotton candy = $5.25
Number of friends = 4
So, the expression is given as
Expression = 5.25(4)
Express 4 as 1 + 1 + 1 + 1
So, we have the following representation
Expression = 5.25(1 + 1 + 1 + 1)
Open the bracket
Expression = 5.25 + 5.25 + 5.25 + 5.25
Hence, the other expression is 5.25 + 5.25 + 5.25 + 5.25

Emma works at the library putting books away. She put away 3 carts ofbooks in 45 minutes. The function f(b) represents the number of booksEmma put away per hour. Which of these statements are correct interpretations of the function?a) The term 3b represents the number of books Emma puts away in an hour .b) The variable b represents the number of book on one cart .c) The number 3 represents the number of hours Emma worked .
You have the following function:
f(b) = 3b ÷ 45/60
Consider Emma put way 3 carts of books in 45 minuntes.
The factor 45/60 means the conversion to hours of the number of books Emma put way. 45 minutes in hours is the same as 45/60.
the factor 3b means that Emma put way 3 carts of books, and the division stablish the rate of time in one hour. This means b is the number of book on one cart.
Hence, the following statement is a correct interpretation of the function f(b):
b) the variable b represents the number of book on one cart.

Write an expression that represents the change in elevation
What was the change in elevation?
The expression to represent the change in elevation would be 13 - 150.
The change in elevation would be - 137 feet.
How to find the change in elevation?The change in elevation refers to the difference between the elevation that a person ends up in, from the elevation that they started out at.
The change in elevation for the goat would therefore be:
= Ending elevation - Starting elevation
= 13 - 150
= - 137 feet

We see that 22 and 23 are Choose one And since the lines u and y are parallel, 22 and 23 are Choose one So, mZ3 = ° We see that 21 and 22 are Choose one Thus, 21 and 22 are Choose one So, mZ1 = 1 Therefore, 21 and 23 are Choose one We also see that 21 and 23 are Choose one < The relationship between 21 and 23 is an example of the following rule. When parallel lines are cut by a transversal, Choose one
Answers:
We see that ∠2 and ∠3 are corresponding angles
And since the lines u and v are parallel, ∠2 and ∠3 are congruent.
So, m∠3 = 150
We see that ∠1 and ∠2 are vertically opposite angles
Thus, ∠1 and ∠2 are congruent
So, m∠1 = 150
The relationship between ∠1 and ∠3 is an example of the following rule
When parallel lines are cut by a transversal, alternate interior angles are congruent.
Explanation:
The angles formed by two parallel lines and a transversal that are on the same side of the transversal and in the same position from the parallel lines are called corresponding angles. These angles have the same measure so they are also congruent.
So, we can fill the first part as:
We see that ∠2 and ∠3 are corresponding angles
And since the lines u and v are parallel, ∠2 and ∠3 are congruent.
So, m∠3 = 150
On the other hand, two opposite angles formed by two lines that cross are called vertically opposite. So, these angles have the same measure.
So, we can fill the second part as:
We see that ∠1 and ∠2 are vertically opposite angles
Thus, ∠1 and ∠2 are congruent
So, m∠1 = 150
Finally, we can fill the third part as:
The relationship between ∠1 and ∠3 is an example of the following rule
When parallel lines are cut by a transversal, alternate interior angles are congruent.
Because alternate interior angles are the angles that are inside the parallel line and on opposite sides of the transversal.
12g + 21 and 3(4g + 7) are equivalent. true or false
Answer: TRUE
Step-by-step explanation:
12g+21 equals to 3(4g+7) because you have to multiply 3 and 4g which will equal 12g and then multiply 3 and 7 which will equal 21.
So your final answer would be 12g+21 equals to 12g+21.

solve y=5x-3 -x+7y=-21
Given the equation system:
[tex]\begin{gathered} y=5x-3 \\ -x+7y=21 \end{gathered}[/tex]You can find the solution to this equation system using the subtitution method.
Since the first expression is written in terms of y, you can replace it into the second expression and calculate for x
[tex]\begin{gathered} -x+7y=21 \\ -x+7(5x-3)=21 \end{gathered}[/tex]-Distribute the multiplication on the parentheses term:
[tex]\begin{gathered} -x+7\cdot5x-7\cdot3=21 \\ -x+35x-21=21 \end{gathered}[/tex]-Simplify the x-terms, by solving the operation between them
[tex]34x-21=21[/tex]-Pass 21 to the right side of the equation by applying the opposite operation to both sides of the equal sign
[tex]\begin{gathered} 34x-21+21=21+21 \\ 34x=42 \end{gathered}[/tex]-Finally, divide both sides of the equation by 34 to determine the value of x
[tex]\begin{gathered} \frac{34x}{34}=\frac{42}{34} \\ x=\frac{21}{17} \end{gathered}[/tex]Now that we have determined the value of x, we can replace it into the first equation to calculate the value of y:
[tex]\begin{gathered} y=5x-3 \\ y=5(\frac{21}{17})-3 \\ y=\frac{105}{17}-3 \\ y=\frac{54}{17} \end{gathered}[/tex]This system has one solution at the point
