Name a pair of adjacent complementary angles
Answers
Supplementary angles are two angles with a sum of 180º.
Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X.
In geometry, complementary angles are two angles whose measures add up to 90 degrees. A pair of adjacent complementary angles could be 30 degrees and 60 degrees.
Explanation:In geometry, complementary angles are two angles whose measures add up to 90 degrees. For example, if one angle measures 30 degrees, the other angle measures 60 degrees because 30 + 60 = 90. So, a pair of adjacent complementary angles could be 30 degrees and 60 degrees.

if 1 factor of 3x3+7x2-7x-3 is (x+3) what are the other two factors
Answers
= (x + 3)(x - 1)(3x + 1)
answer
other two factors (3x + 1) and (x - 1)
To find the remaining factors of the polynomial 3x^3+7x^2-7x-3 after knowing that (x+3) is a factor, divide the polynomial by x+3 and then factor the resulting quadratic polynomial.
If x+3 is a factor of the polynomial 3x3+7x2-7x-3, the other two factors can be found by performing polynomial long division or synthetic division to divide the polynomial by x+3. Once the polynomial is divided, the quotient will be a quadratic equation, which we can then factor or use the quadratic formula to find the remaining factors.
Steps for Polynomial Division:
Divide the polynomial 3x3+7x2-7x-3 by x+3.Obtain the quotient, which should be a quadratic polynomial.Factor the quadratic polynomial or use the quadratic formula to find the other two factors of the original polynomial.The coordinates of the vertices of a polygon are (−5, 1) , (−1, 3) , (2, 3) , (2, −2) , and (−3, −1) .

if three times x is equal to x decreased by 2, then x is
Answers
"Three times x" means 3x.
"x decreased by 2" means x - 2
"Three times x is equal to x decreased by 2" means 3x = x - 2
Let's solve for x:
3x = x - 2
Subtract x from both sides:
3x - x = x - x - 2
2x = -2
Divide both sides by 2:
2x = -2
(2x)/2 = -2/2
x = -1

Eddie is reading a novel for English class he has read 173 out of 480 pages about what percent of the book has he read
Answers
Answer: The percent of the book has he read is 36.04 %.
Step-by-step explanation:
Given: The number of pages read by Eddie= 173
The total number of pages = 480
The percent of the book has he read is given by:_
[tex]P=\frac{\text{number of pages read}}{\text{total pages}}\times100\\\\\Rightarrow\ P=\frac{173}{480}\\\\\Rightarrow\ P=0.36041\times100\\\\\Rightarrow\ P=36.04\%[/tex]
Hence, the percent of the book has he read is 36.04 %.

He calls the farrier (a person who puts shoes on horses) but has a difficult time remembering how many of each animal he owns. He knows that there are a total of 24 animals. The animals have a total of 62 legs (all animals have either two or four legs). How many horses does Tom own?

Triangle MNP is the image of triangle JKL after a 120 degrees counterclockwise rotation about point Q. If the measure of angle L is 47 degrees and the measure of angle N is 57 degrees, determine the measure of angle M. Explain how you arrived at your answer.
Answers
The measure of angle M in triangle MNP is 76 degrees. This is determined by utilizing the sum of interior angles property of triangles and understanding the correspondence of angles in rotated or transformed figures.
Explanation:The problem given is associated with the geometry of triangles. From the problem statement, we know that triangle MNP is the image of triangle JKL after 120 degrees counterclockwise rotation. This indicates that the angles of both triangles are the same. Hence, angle M will correspond to angle J of the original triangle.
However, since we are not given the measure of angle J, we need to calculate it using the property of triangles. In triangles, the sum of the interior angles amounts to 180 degrees. Therefore, the measure of angle J can be found by subtracting the measures of the other two angles (angle K and angle L) from 180 degrees.
Given the measure of angle L is 47 degrees and the measure of angle N (which corresponds to angle K in triangle JKL) is 57 degrees, we use the equation:
Angle J = 180 - (angle K + angle L) = 180 - (57+47) = 76 degrees.
Thus, the measure of angle M in triangle MNP, which is corresponding to angle J in triangle JKL, is 76 degrees.

Consider the function represented by the graph. What is the domain of this function
Answers
Answer: The answer is [tex]\{x:x\geq 0\}.[/tex]
Step-by-step explanation: We are given a graph that represents a function. We are to find the domain of the graphed function.
Domain and Range: If y=f(x) is a function, then the domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements of ordered pairs (y-coordinates).
In the given graph, 'x' takes the values from 0 to infinity and 'y' takes the values from negative infinity to 9.
Therefore, domain of the function is [0, ∞) and the range is (-∞, 9).
Thus, the domain is given by the set [tex]\{x:x\geq 0\}.[/tex]

There is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax. What is the sales tax on the second item?
Answers
Answer:
its 19
Step-by-step explanation:
If a second item costs $294.50 before tax. The sales tax on the second item will be $19.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, there is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax.
We have to apply the ratio as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
$6/$93 = t/$294.5
t = 6 × 294.5 / 93
t = $ 19
Thus, if a second item costs $294.50 before tax. The sales tax on the second item will be $19.

This isosceles triangle has two sides of equal length , a, that are longer than the length of the base , b. The perimeter of the triangle is 15.7 cm. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 cm, which equation can be used to find the length of the base ?
Answers
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
